Saul, who had a good reputation, changed into Paul. In much the same way, T. Colin Campbell, author of The China Study, underwent a major transformation. In The China Study, CAMPBELL summarizes an overwhelming amount of evidence from renowned scientists and shows that eating significantly less animal protein is the most important step in preventing common lifestyle diseases. He also discusses the fact that it is often possible to cure yourself by making changes to your diet.

Since the food and pharmaceutical industries have almost unlimited means and actively prevent change toward a healthy diet, evidence of this magnitude is required for the public to have a change of opinion. Business, government, media, and the health care system are closely linked. A good fable (lie) persists forever. But understanding the truth requires the ability to perceive and think.


The images below serve to break up the text and provide space for additional comments. The book itself contains few pictures, but it does have numerous tables. These images are from Wikipedia, taken by me, or have public domain status.

The author, CAMPBELL, describes quite convincingly how he swore by animal protein as a child and young adult. His dissertation was also based on his conviction that animal protein was of particular importance. He wanted to promote a higher consumption of meat, milk, and eggs as he believed this would help to improve people’s overall health. For a number of years, the author worked on a related project in the Philippines.

During this ten-year project, the main goal was to get children to eat more animal protein. One of the ways they did this was to establish “self-help” education centers. Then he discovered that “Children who ate the highest-protein diets were the ones most likely to get liver cancer” (p. 5).

The author then found out that rat experiments conducted in India had come to the same conclusion, but the results were considered implausible. However, his team came to the same results with experiments using transgenic mice. It is not genes that are the deciding factor of whether a person falls victim to one of the ten leading causes of death; instead, it is what they eat.

Tasty, healthy, and raw

Roasted and salted foods are
unhealthy and cause cravings.

Unhealthy choice for when you’re
on the go

This was a defining moment for CAMPBELL.

The tests carried out by his team over a period of 27 years were funded by major national institutions and verified a second time by some of the best scientific journals. The results were shocking for scientists: a low-protein diet inhibited the development of cancer caused by aflatoxin. This type of diet also inhibited any existing cancer growth.

Some proteins did not promote cancer. However casein, which makes up to 87% of the protein in cow’s milk, promoted all stages of cancer growth. Plants, on the other hand, delivered safe proteins.

Dr. CAMPBELL writes how four decades of biomedical research und results of long-term studies have shown (with provocative results) that a healthy diet can save your life. He then lists out the following benefits:

Dietary change can enable diabetic patients to go off their medication.
• Heart disease can be reversed with diet alone.
• Breast cancer is related to levels of female hormones in the blood, which are determined by the food we eat.
• Consuming dairy foods can increase the risk of prostate cancer.
• Antioxidants, found in fruits and vegetables, are linked to better mental performance in old age.
• Kidney stones can be prevented by a healthy diet.
• Type 1 diabetes, one of the most devastating diseases that can befall a child, is convincingly linked to infant feeding practices
 (p. 3).

He came to these conclusions after conducting a massive human study in which 6,500 Chinese from rural areas in several different provinces of China participated. Two universities in the United States and one in China worked jointly on the project—under the direction of the author.

Finally, CAMPBELL concludes that the boundaries between politics, government, the food industry, pharmaceutical companies, science and medicine have blurred over time. Justice and health are the losers. Since this is not recognized for what it is, it is more dangerous than corruption.

“The result is massive amounts of misinformation, for which average American consumers pay twice. They provide the tax money to do the research, and then they provide the money for their health care to treat their largely preventable diseases” (p. 8).

Since these facts are so contrary to the information provided by the food industry, government, medicine, and others, you may find them hard to accept unless you have already discovered this information on your own or you actually read the book, which contains overwhelming evidence from studies of many leading scientists.

The main author didn’t gain fame because of this book or his work in China. It’s quite the reverse; he received this large and important task because of his reputation, his integrity and his ability. You cannot compare this book with one written by an author who made a name for himself by publishing his own views as this book is written by a person with great professional and personal credibility. It includes 708 references, which are listed out for each chapter at the end of the book.

Since much sound and convincing evidence was required for these conclusions, my book review is much longer than it would usually be. The findings are extensive.

The book begins with a preface by Howard Lyman, author of Mad Cowboy. He respects COLIN CAMPBELL because of his courage and integrity and explains how even with solid evidence not much is able to be done against the mainstream.

Lyman served as codefendant for Oprah Winfrey when some cattlemen sued her after she announced her intention not to eat beef any more.

The foreword was written by John Robbins, author of Diet for a New America, Reclaiming Our Health, and The Food Revolution. Robbins writes, “It’s easier to find a Snickers bar, a Big Mac or a Coke than it is to find an apple. And your kids eat at a school cafeteria whose idea of a vegetable is the ketchup on the burgers.”

Robbins then describes the glossy magazine called Family Doctor: Your Essential Guide to Health and Well-Being, which all doctors in the US get for free from the American Academy of Family Physicians. It is filled with full-page ads for McDonald’s, Dr Pepper, and the like and advertising for chocolate pudding and Oreo cookies. It is similar in Europe, but perhaps even more sophisticated. There you will find ads paid for by convenience food manufacturers (PR, public relations) in which “so-called dieticians stress the advantages of instant soups and frozen foods.” Critical scholars at Yale University call it a toxic food environment.”

Robbins describes The China Study as a “brave and wise book” and the author as a “man of humility and human depth.” Robbins adds, “He always shows you how he has arrived at his conclusions.” Robbins mentions some of the aspects in the book that he feels to be most important and interesting.

Dr. Gunter R. Neeb, from Idstein, Germany, wrote the preface for the German edition. He is a practitioner of traditional Chinese medicine and has been a visiting professor at numerous universities around the world (Since some of the information in the German edition is of particular interest, I have included it in this book review as well).

Neeb writes that The China Study, the largest epidemiological study on the human diet ever conducted, would not be easy for people to believe as the subject matter is too different and unfamiliar. He thought that this would be the case even though the evidence cited in the book on hundreds of substudies is very convincing and believable. The conclusions are based on studies that involved more than 10,000 test subjects over a period of more than 20 years.

He continues, “It says in the book, for example, that dairy products accelerate tumor cell division, presumably through cell stimulation caused by IGF-1 (somatomedin C). Yet doctors still recommend emaciated oncology patients to increase their protein intake by means of consuming more concentrated dairy products such as cheese and yogurt.”

IGF-1 is a kind of insulin-like growth factor (insulin-like growth factor 1), also called somatomedin C (SM-C).

Wikipedia on the problems with IGF-1:
“It is now widely accepted that signaling through the insulin/IGF-1-like receptor pathway is a significant contributor to the biological aging process in many organisms. ... Reduced IGF-1 signaling is also thought to contribute to the ‘anti-aging’ effects of calorie restriction. ... The IGF signaling pathway has a pathogenic role in cancer. Studies have shown that decreased levels of IGF lead to decreased growth of existing cancer cells. People with Laron syndrome
have also recently been shown to have a much lower risk of developing cancer.”

Neeb criticizes how the German Nutrition Society, whose members include many business organizations, “plays down” these facts. This is particularly frustrating since studies demonstrate that not only the insulin-like growth factor IGF-1 of cows (bovine IGF) enters the bloodstream, but also the production of human IGF-1 is increased by the casein found in milk. See also this book review on the dangers of milk.

Neeb further mentions that consumers are not informed about the different effects of externally supplied vitamin D (cholecalciferol and calcium) and its role in the causation of breast cancer and osteoporosis versus active vitamin D (calcitriol) obtained through sunlight. He suspects the reason for this is that sunlight is free and doesn’t offer any business opportunities for the industry.

After reading The China Study, Dr. Neeb changed over to a nearly vegan (some fish) diet, and he now swears by this “modern” diet.

The liver binds the storage form calcidiol (25(OH)vitamin-D3) to the vitamin D-binding protein (gc-globulin), which the kidney activates, and it becomes the active compound calcitriol (1α,25(OH)2Vitamin D3). The medium to longer-term supply of vitamin D is best determined through the level of 25(OH)Vitamin D3. The bound calcidiol has a biological half-life of about 19 days in the blood. The 25(OH)Vitamin-D3 level in the blood shows the supply over the last three to four months, while the vitamin D3 level shows only the supply over the last few hours to days.

It is best to get your vitamin D from the sun. However, people in northern countries often get too little sun exposure. In 100 g of food, young salted herring contains 27 µg, salmon 16 µg, veal 3.8 µg, avocado 3.43 µg, and mushrooms 1.9 µg. For vitamin D, 1 IU = 0.025 µg of vitamin D3 = 65.0 pmol. IU stands for international unit. The IU is usually a randomly selected, reproducible drug dosage based on its effect rather than its amount. The World Health Organization defines these units.

Summary on Amazon

You can find a summary of The China Study on Wikipedia by clicking here.

On amazon.de, the book is described as follows:

“Be healthy and let animals live!

Even small amounts of animal products can have a negative impact on our health. In this book, you will find the scientifically based answers as to why this is. If we only all knew what already is considered a proven fact in science: that there is a direct relationship between diet and the development of chronic diseases!

Renowned nutritionist T. COLIN CAMPBELL led the China Study, the most comprehensive study of diet, lifestyle, and disease in the history of biomedical research. Two Western universities and the Chinese Academy of Preventive Medicine participated.

The study shows clear links between a diet high in animal protein and the development of chronic diseases. To substantiate the benefits of a vegan diet, the authors have evaluated hundreds of other nutritional studies. The results are included in this book and presented in a clear and understandable way. Our eating habits affect our general health and also the development of cancer, coronary heart disease, diabetes, obesity, and autoimmune diseases such as multiple sclerosis and rheumatism.

The authors give practical advice on how we can combat chronic diseases and existing damage to our health simply by eating a vegan diet.”

Personal comments

I refer to both authors with the name CAMPBELL, father Dr. T. Colin Campbell (PhD in nutrition, biochemistry, and microbiology) and son, Dr. Thomas M. Campbell II, MD. I normally write using the singular, but in certain places, I do write using the plural and title “Drs.” to make it clear that I am referring to two authors. The introduction, which is more than eight pages long, contains several interesting statements, such as the following: “But the real science has been buried under a clutter of irrelevant or even harmful information—pseudoscience, fad diets, and food industry propaganda.” Wikipedia has an entry for the China-Cornell-Oxford project.

The book reviews of Salt Sugar Fat by Michael Moss, which deals with the American situation and Lügen Lobbies Lebensmittel (Lies lobbies food), which looks at the situation in the EU, take up the problem of younger readers who eat a large amount of convenience foods and junk food.

This book, however, is addressed to “typical Western consumers,” who probably think they are eating a healthy diet.

The general public really doesn’t eat a healthy diet, and this is reflected in the large number of lifestyle diseases. These usually only develop after a few decades, similar to the problems connected with tobacco smoking.

The danger is that we often don’t notice that our health is deteriorating because this happens very slowly over several decades. And we often look to those around us when it comes to determining what is right or healthy. We consider lifestyle diseases normal.

Here is a link to a book review of Die Ernährungslüge (The nutrition lie), which deals with the additives in our food.

Book Review

Dr. CAMPBELL states that he was part of the system at the highest levels for nearly fifty years (at that point). He also describes why we now are where we are. For this, he lists out several important points:

  • Synthetic chemicals in the environment and in your food, as problematic as they may be, are not the main cause of cancer. 
  • The genes that you inherit from your parents are not the most important factors in determining whether you fall prey to any of the ten leading causes of death.
  • The hope that genetic research will eventually lead to drug cures for diseases ignores more powerful solutions that can be employed today.
  • Obsessively controlling your intake of any one nutrient, such as carbohydrates, fat, cholesterol, or omega-3 fats, will not result in long-term health.
  • Vitamins and nutrient supplements do not give you long-term protection against disease.
  • Drugs and surgery don’t cure the diseases that kill most Americans.
  • Your doctor probably does not know what you need to do to be the healthiest you can be (p. 2).

Dr. CAMPBELL writes how four decades of biomedical research und results of long-term studies have shown (with provocative results) that a healthy diet can save your life. He then lists out the following benefits:

  •  Dietary change can enable diabetic patients to go off their medication.
  •  Heart disease can be reversed with diet alone.
  •  Breast cancer is related to levels of female hormones in the blood, which are determined by the food we eat.
  •  Consuming dairy foods can increase the risk of prostate cancer.
  •  Antioxidants, found in fruits and vegetables, are linked to better mental performance in old age.
  •  Kidney stones can be prevented by a healthy diet.
  •  Type 1 diabetes, one of the most devastating diseases that can befall a child, is convincingly linked to infant feeding practices (p. 3).

Based on the experiences my wife and I have had and the experiences of others we know who have also changed their diet, I can confirm that both the first two statements and the fourth statement quoted here are very true. But most doctors would probably still say that it can’t be that easy.

Usually the reason for such a reaction is ignorance and doesn’t have to do with money at all. Medical school does not include in-depth study of nutrition. And nutritional guidelines are largely determined by the food industry.

After reading The China Study or this text, a responsible doctor would want to inform patients about what actions they should take on their own. This would be an adjuvant to the treatment provided. If the patients aren’t interested, at least the doctor would have done his or her best.

The results of the hundreds of studies summarized in The China Study provide evidence that proper nutrition is the most powerful weapon against disease. CAMPBELL also explains why misinformation or even disinformation persists so stubbornly. He believes that half of the American people are suffering from health problems that require them to take prescription drugs regularly. Hundreds of millions of Americans have elevated cholesterol levels.

Further processing

I think this situation is making its way to Europe as well. Such a book doesn’t usually reach the masses. And neither do the findings. And if this were to happen, the information would normally be dismissed. This information will therefore most likely benefit only a very small part of the population. Above all, the readers themselves must be interested in reading something like this; in other words, it’s the readers responsibility to inform themselves, not the authors responsibility to make sure they do so. But I am definitely still committed to this cause.

Dr. CAMPBELL writes on page 4: “I just ate what everyone else did: what I was told was good food. We all eat what is tasty or what is convenient or what our parents taught us to prefer.” He grew up on a dairy farm, where milk production was the major food and income source. His dissertation at Cornell University was about better methods for faster growth of cows and sheep. He wanted to promote a higher consumption of meat, milk, and eggs as he believed this would help to improve people’s overall health.

The author was the last graduate student under the guidance of Professor Clive Maine McCay (1898–1967). Clive McCay was known for conducting experiments with rats in which they were fed much less food than they would normally eat. These rats actually had significantly longer and more active lives than rats that were allowed to eat as much as they pleased. The same thing happened with dogs. McCay died from a serious illness.

At the Massachusetts Institute of Technology (MIT), CAMPBELL then investigated why millions of chicks were dying as a result of an unknown toxic chemical in their food und determined that dioxin was the cause (polychlorinated dibenzodioxins and dibenzofurans), probably the most toxic chemical compound. See also this devastating story of the Seveso disaster and information about the Ukraine and Victor Yushchenko, who ingested the carcinogen TCDD. This is what humanity does to itself.

Original: "I initially worked at MIT, where I was assigned a chicken feed puzzle. Millions of chicks a year were dying from an unknown toxic chemical in their feed, and I had the responsibility of isolating and determining the structure of this chemical. After two and one-half years, I helped discover dioxin" ... (p. 4)

After that, CAMPBELL examined the unusually high incidence of primary liver cancer in children in the Philippines. For ten years, the main goal of this development aid project was to get children to eat more animal protein. One of the ways they did this was to establish “self-help” education centers. Then he discovered that “Children who ate the highest-protein diets were the ones most likely to get liver cancer” (p. 5).

He next heard about some rat experiments in India. The rats there received carcinogenic aflatoxin. One group was given 20% protein in their diet, the other 5%—both groups received the same amount of aflatoxin. The result was that all of the rats receiving 20% protein developed liver cancer. But with the group receiving only 5%, there were no cases of cancer! It was heretical to claim that a high-protein diet was unhealthy. This was contrary to everything he had learned before. It was a defining moment for CAMPBELL.

The tests carried out by his team over a period of 27 years were funded by major national institutions and verified a second time by some of the best scientific journals. The results were shocking for scientists: a low-protein diet inhibited the development of cancer by aflatoxin. This type of diet also inhibited any existing cancer growth.

Some proteins did not promote cancer. However casein, which makes up to 87% of the protein in cow’s milk, promoted all stages of cancer growth. Plants, on the other hand, delivered safe proteins.

Again, I confirm his findings on the basis of my own experiences and that of others I know. My life expectancy in 1978 was only an additional 2.6 years. However, with such a short life expectancy, I didn’t want to go through surgery and chemotherapy, but instead wanted to start anew and make a radical lifestyle change.

Finally, CAMPBELL concludes that the boundaries between politicsgovernment, the food industrypharmaceutical companies, science, and medicine have blurred over time. At best, they represent a mix between the making of profit and what is best for society. Justice and health are the losers. The problems are much more subtle than, for example, corruption and therefore are also much more dangerous. “The result is massive amounts of misinformation, for which average American consumers pay twice. They provide the tax money to do the research, and then they provide the money for their health care to treat their largely preventable diseases” (p. 8).

Part I: The China Study

The actual China Study is covered in the chapter “Lessons from China” on 40 pages. Before this, we learn interesting things about CAMPBELL’s life that also show how he made the transformation from a Saul to a Paul in the biblical sense, something that only few people are able to accomplish. The rest focuses on the findings from The China Study and the reasons why these have not yet been truly put into practice.

Problems We Face, Solutions We Need (p. 11)

CAMPBELL tells briefly about growing up on a farm, the heart attack his father suffered at age 61, and his father’s death at age 70 due to coronary artery occlusion.

Eating his meat-based Atkins diet, Dr. Robert Atkins lived only one year longer than CAMPBELL’s father. He died in 2003 at the age of 71 from stroke complications. According to Wikipedia, Atkins had previously suffered from a long history of illness, including myocardial infarction, heart failure, and high blood pressure. His profession: cardiologist!

CAMPBELL includes a graph showing that 47% of men and 38% of women are likely to contract cancer. Readers can see that cancer death rates increased from 1972 to 1992 rather than decreased. At the same time, the percentage of obese (BMI = >30) people in the population more than doubled from 1976 to 1999. Expenses for diabetes alone are around $100 billion a year. CAMPBELL highlights studies showing that a healthy diet not only has the ability to prevent coronary artery disease (also coronary heart disease) but can also partially reverse it (p. 3).  

In the meantime, treatment costs have spiraled out of control. In 1997, a trillion dollars or $3,912 per person was spent on health care in the US. This is more than twice as much per person as compared to Japan ($1,760), which, if we disregard microstates like Monaco, is the country with the highest life expectancy. Germany spent $2,364 per person.

OECD data from 2009 shows that health care costs increased to $7,290 per person in the US, $3,588 in Germany, $3,763 in Austria, and $4,417 in Switzerland.

These costs also rose considerably based on gross national income (see also GDP and GNP) and in 2009 were at 16 percent of the GDP in the United States. The US, in particular, is expecting more rapid rises in health care costs.

CAMPBELL discusses the first wave of promised weight loss in the 1970s, which began with a protein drink. Within a short period of time, almost 60 women died from this diet (life expectancy). Other diets soon appeared on the market and received similar praise, for example, Dr. Atkins diet, Protein Power, and the South Beach Diet. In many cases, these have led to dangerous health problems (p. 19).

The author also states that diets from “health” books such as Sugar BustersThe Zone, or Eat Right For Your Type have made health information even more confusing for consumers who are interested in learning about how to improve their diet. He regrets that scientists focus on details such as extremely specific food components, rather than taking the broader scope into consideration. The consequences are contradictions (falsificationism), misleading fad diets (food faddism), and consumer uncertainty. For him, these kinds of fad diets and emphasis on individual dietary components such as vitamin E or calcium supplements embody “the worst of medicine, science and popular media.”

Dr. T. COLIN CAMPBELL writes, “I did not begin with preconceived ideas, philosophical or otherwise, to prove the worthiness of plant-based diets. I started at the opposite end of the spectrum: as a meat-loving dairy farmer in my personal life and an ‘establishment’ scientist in my professional life. I even used to lament the views of vegetarians as I taught nutritional biochemistry to pre-med students” (p. 21).

That the author lists out his numerous works and extraordinary awards may seem a bit arrogant to some readers. However, there are so many “experts” and charlatans in the field of nutrition that it is necessary for him to list out his qualifications. How else would readers be able to evaluate this new and impressive evidence?

In the book, the author doesn’t explain why he does this. But we are reading something from a highly respected top scientist and results from large-scale studies. These were conducted in collaboration with two US universities and numerous other professors. As the author or coauthor, he has written 350 scientific papers. These have included large-scale human studies as well as animal studies. Collaboration with the Chinese for The China Study began in the early 1980s.

CAMPBELL explains how the findings from these studies were met with resistance. Since many medical professionals are not familiar with the subject, they either have difficulty accepting the following statement or can’t accept it at all: “Additionally, impressive evidence now exists to show that advanced heart disease, relatively advanced cancers of certain types, diabetes, and a few other degenerative diseases can be reversed by diet” (p. 23).

I frequently hear doctors and sick people making the excuse that certain diseases are the result of genetics. Of course, genetic predisposition is an important factor, but the following statement is also true: “We now know that we can largely avoid these ‘genetic’ diseases even though we may harbor the gene (or genes) that is (are) responsible for the disease” (p. 23).

A proper diet not only prevents or reduces diseases, it also generates physical and mental well-being. To this effect, CAMPBELL lists some world-class athletes such as Ironman triathlete Dave Scott, track and field stars Carl Lewis (vegan since 1990) and Edwin Moses, and tennis ace Martina Navratilova. He also mentions the 68-year-old marathoner Ruth Heidrich. Ruth Heidrich is on the list of notable vegans on Wikipedia.

Human studies conducted by Dr. Russell Henry Chittenden (1856–1943) a century ago at Yale University describe superior physical performance in people on a purely vegan diet (only plant-based foods). This was confirmed by rat experiments carried out by the author. He came to the conclusion that fewer people would have to spend their final years with lengthy and costly battles against chronic diseases in hospitals. His motto: “It is time to stand up, clear the air, and take control of our health” (p. 25).  

A House of Protein (p. 27)

Nitrogen-containing protein has been considered the most sacred of all nutrients since it was discovered by Dutch chemist Gerardus Johannes Mulder in 1839. The word “proteios” even means “of prime importance.” In the 19th century, protein was considered tantamount to meat or foods of animal origin. This myth still exists, even among physicians.

German physiologist Carl von Voit (1831–1908) discovered that humans need 48.5 g of protein, but still recommended 118 g per day. He thought that too much of a good thing didn’t exist. What a setback this caused because of his ignorance of the fundamental laws of nature!

Several students under Voit adopted this concept without critical inspection. W.O. Atwater (1844–1907) even advocated 125 g daily when he was head of the USDA. Today, the recommendation is less than half this. Max Rubner (1854–1932) believed that “a large protein allowance is the right of civilized man” (p. 29).

CAMPBELL notes that protein is essential to life and after digestion provides essential amino acids, which are used for the development of new cells and other processes. He explains that with the past euphoria about high-quality protein—with a composition as close as possible to human protein—actually human flesh would be the best. But of course, we don’t act like cannibals, but instead turn to animals.

It was not until a few years ago that scientists discovered that animal protein, which was seen as the best quality protein (biological value), does not result in the best health, but that it is rather quite the opposite. For over a hundred years, we have believed that “more quality equals more health” (p. 31).

We then read about “a mountain of compelling research showing that ‘low-quality’ plant protein, which allows for slow but steady synthesis of new proteins, is the healthiest type of protein. ...

We now know that through enormously complex metabolic systems, the human body can derive all the essential amino acids from the natural variety of plant proteins that we encounter every day” (p. 31).

It makes sense then that the West tries to help starving people in developing countries primarily by providing them with protein sources. The author describes how Professor Charlie Engel (1912–2007, actually Ruben W. Engel), the head of the Department of Biochemistry and Nutrition at Virginia Tech at the time, recruited him in 1967 to work on a “mothercraft” project in the Philippines. As a staunch meat eater, CAMPBELL wanted to teach the mothers of malnourished children about what types of locally grown foods would be best for their children. He did this as part of his job as campus coordinator, with several extended stays on-site.

Peanuts were to be developed as a primary source of protein, but there was a high incidence of liver cancer in the area due to the aflatoxin found in peanut butter. The good peanuts were sold as cocktail nuts, but the moldy ones ended up in factories and were used to make peanut butter.

Peanut butter is similar to the Western diet, and in the Philippines, only wealthy families were able to afford this “more healthy food.” Their children were also the ones to be affected with liver cancer most often, which in the West doesn’t usually occur until about age 40.

At the same time, a study was being conducted in India comparing liver cancer incidence in rats with the amount of protein they consumed. Rats were either given 5% or 20% protein, and both groups received the same amount of aflatoxin. All of the rats receiving 20% protein developed liver cancer or the prior typical cell damage, but not a single rat in the other group showed any detectable signs. “No one seemed to accept the report from India” (p. 37).

On a flight, CAMPBELL happened to meet a former colleague from MIT, Professor Paul Newberne, who was studying the relationship between diet and cancer at the time. He vehemently denied that there was any relationship between the two and believed that the opposite was true.

The author explains how different the process of “establishing scientific proof” is in the areas of physics, medicine, and medical research.

If you ask the question, does a ball fall down when we throw it in the air, we know the answer and it is 100% correct. But the question if a person smokes four packs of cigarettes a day, will they get lung cancer, can only be answered with a “maybe.” CAMPBELL stresses that statistics only provide percentages but can’t give a reliable prognosis for an individual person.

He then explains the various strategies and possibilities used in investigations. Researchers usually confirm or reject hypotheses by means of comparisons, measurements, and observations. Correlation and causality are used to describe these. The China Study is based primarily on the cause-and-effect relationship, that is causality from a holistic perspective. “We observed whether there were patterns of associations for different dietary, lifestyle and disease characteristics within the survey of 65 counties, 130 villages and 6,500 adults and their families” (p. 39).

CAMPBELL stresses the importance of finding root causes. For example, there is a greater incidence of heart disease in countries that have more telephone masts. So these are positively correlated, but that is not causality because relevance is not a given. Telephone poles don’t cause heart disease.

The China Study utilized more than 8,000 statistically significant correlations. The statistical significance is also of importance. If an investigation proves with the probability of 95% that chance didn’t play a role, the result is significant, and at 99% it is highly statistically significant. Known mechanisms of action: the results of other studies are capable of strengthening the reliability of a result or decreasing it. Meta-analyses of a variety of studies may potentially improve certainty.

The greatest dangers are animal proteins (meat, eggs, milk, and dairy products), pasta, and baked goods.

We rarely know the all-important background information of such studies or meta-studies. And when a strong representation from the industry is behind these, the result is problematic. You can almost count on it—if something hits the tabloids, consumer magazines, and the like, it is most likely supported by financial interest groups and you will only be reading part of the story.

Turning Off Cancer (p. 43)

The author describes how Americans react with panic to any report about carcinogens. He gives the example of how it used to be common practice to routinely spray Alar, a chemical that was used as a growth regulator. CAMPBELL then lists out other carcinogenic substances such as DDT, nitrites, and artificial sweeteners.

He next explains how such scientific publications come into being. As an example, he tells about a study using rats that looked at nitrosamine (N-nitrososarcosine). Even the “low-dose” group received extremely high levels of NSAR. As a comparison, to get the equivalent amount of NSAR, you would have to eat a bologna sandwich with a pound of meat on it every day for thirty years. That would be 270,000 bologna sandwiches! Nevertheless, this report received so much attention that even the consumer advocate Ralph Nader, stated that hot dogs were “among America’s deadliest missiles” (p. 46).

CAMPBELL then describes the three stages of cancer (carcinogenesis): initiation (for lipid peroxidation as well), promotion, and progression. Another term for progression is metastasis. He includes a chart that clearly illustrates the four steps of initiation with aflatoxin. Aflatoxin enters a liver cell, it gets metabolized by an enzyme, and converted into a dangerous product, which attacks the cell’s DNA. Sometimes the cell multiplies before the damaged deoxyribonucleic acid (DNA) gets repaired, and then permanently damaged, cancerous cells arise.

As part of a study he conducted, CAMPBELL investigated the mixed-function oxidase (MFO) enzyme, which is very complex and acts as a catalyst to convert various materials. This serves to detoxify aflatoxin, but also activates in, converting it into aflatoxin metabolites. Just changing the amount of protein consumed strongly alters the enzyme activity (catalytic activity).

Experiments conducted by Dr. CAMPBELL’s undergraduate student, Rachel Preston, showed that when the milk protein (casein) was 5% of the total food intake, instead of 20%, the dangerous aflatoxin-DNA adducts decreased dramatically. The results were as follows:

  • Less aflatoxin entered the cell.
  • Cells multiplied more slowly.
  • Multiple changes occurred within the enzyme complex to reduce its activity.
  • The quantity of critical components of the relevant enzymes was reduced.
  • Less aflatoxin-DNA adducts were formed.

Conclusion: “Lower protein intake dramatically decreased tumor initiation” (p. 53).

This was consistent with the earlier studies in India that had been ridiculed. Another study conducted by Scott Appleton and George Dunaif dealt with the foci, that is microscopic cell clusters that are considered precancerous. They discovered that even if the levels of aflatoxin consumed were much higher, the foci grew a lot less with the 5% protein diet and the same amount of aflatoxin than with the 20% protein diet and less aflatoxin.

The studies carried out by Linda Youngman prove that the process can even be controlled at a later stage, just by changing the amount of protein. Cancer development that has been prevented by a low protein intake can later be stimulated with a lot of protein in the diet without giving aflatoxin. The foci then act as a kind of memory. With more than 10% dietary protein, the foci increase dramatically in response to the increase of protein in the food. Some time later, the Japanese visiting professor, Fumiyiki Horio, came to the same conclusions.

An intake of 10% protein is already considerably more than humans need, but the 10% is recommended in order to ensure adequate intake for virtually everyone. Anything above that is harmful. Americans consume approximately 15–16% protein. As a comparison, a 1.5 ounce (45 g) porterhouse steak contains 13 grams of protein.

A porterhouse steak weighs between 700 and 1000g. Photo Wikipedia/Thiago R. Ramos.

A porterhouse steak weighs 24.5 to 35.5 ounces (700 to 1,000 grams) and is 2½ inches thick (6 cm), while a T-bone steak is 1½ inches thick (4 cm) and weighs about 21 ounces (600 grams).

The bone weight is factored in. But 500 g of meat would “only” be 650 calories and would contain 112 grams of dangerous animal protein plus 22 grams of “bad” fat.

But in the long term, it is the 350 milligrams of cholesterol that is the biggest problem.

After obtaining these results, CAMPBELL had David Schulsinger examine whether or not plant protein acted the same way. The answer is no. Plant protein did not promote cancer, but cow’s milk protein did.

The same results were obtained with completely developed liver cancer. Tumor growth decreased by 35–40% when the animals were given lower levels of milk protein. And despite high aflatoxin levels, 100% of the animals that received only 5% milk protein lived a long life without cancer, whereas none of the animals that received 20% milk protein survived. The book describes the study more fully and in much greater depth.

People who are chronically infected with hepatitis B virus (HBV) are 20–40 times more likely to get liver cancer. To find out how the virus causes liver cancer, researchers bred transgenic mice infected with the virus. CAMPBELL had Jifan Hu, one of his graduate students, and later also Dr. Zhiqiang Cheng study this form of liver cancer in mice. They received the two different strains of transgenic mice. The casein showed the same effect. The details are on page 63 and followed by a chart with images of the different tissues. After this, the author gives reasons why these findings suggest that they are also relevant for humans.

Finally Tom O’Connor and Youping He investigated the effects of fish protein, fats, and carotenoids and their relationship to liver cancer and pancreatic cancer. CAMPBELL writes, “The results of these, and many other studies, showed nutrition to be far more important in controlling cancer promotion than the dose of the initiating carcinogen” (p. 66).

The findings of these experiments: “Nutrients from animal-based foods increased tumor development while nutrients from plant-based foods decreased tumor development.” Another group researching breast cancer and different carcinogens came to the same conclusion (p. 66).

The big question is whether these experimental studies on animals really apply to all different types of cancer and to people. Evidence from a large human study was needed. Dr. Junshi Chen from China made that possible in 1980. And that is what just a little later became The China Study.

Lessons from China (p. 69)

In 1983, the premier of China, Zhou Enlai (1898–1976), was diagnosed with cancer. That is why he initiated a nationwide survey on the occurrence of 12 types of cancer in more than 2,400 Chinese counties and 880 million (96%) of their inhabitants. This is how the most ambitious biomedical project ever came into being—one with 650,000 employees. The result of the project was a map that showed how cancer rates differed greatly according to the area and lifestyle. Some counties had over 100 times the rate of cancer incidence than others. In the US, the ratio is only 1 to 3 from one state to the next. Overall, there were significantly fewer cancer cases in China than in the US.

CAMPBELL lists out the participants of this joint study, the actual China Study: Dr. Junshi Chen, deputy director of the most important government diet and health research laboratory in China, Junyao Li, one of the authors of the Cancer Atlas Survey, Richard Peto of Oxford University (UK), one of the leading epidemiologists worldwide, and Dr. T. COLIN CAMPBELL as the director.

The team looked at the mortality rates of more than four dozen different diseases such as various types of cancer, heart disease, and infectious diseases. They took blood and urine samples from 6,500 adults and recorded all of the foods that these families consumed during a three-day period.

In addition, the team also analyzed food samples from markets across the country. Selecting rural areas where people had lived for generations and had consistent eating habits gave the study great validity with “more than 8,000 statistically significant associations between lifestyle, diet, and disease variables” (p. 73).

The differences between the eating habits in China and the US are enormous. The Chinese who do more physical work ate 2,641 cal/day (findings are standardized for a body weight of 65 kg or 143.3 pounds) compared with 1,989 cal/day in the United States. In the US, people with a body weight of 77 kg (or 169.8 pounds) would eat about 2,400 cal/day. In China, it would be 3,000 cal/day for a body weight of 77 kg (or 169.8 pounds).

“Experimental variation (i.e., a range of values) is essential when we investigate diet and health associations. Fortunately, in the China Study considerable variation existed for most of the measured factors. There was exceptional variation in disease rates (Chart 4.2) and more than adequate variation for clinical measurements and food intakes. For example, blood cholesterol ranged—as county averages—from highest to lowest almost twofold, blood beta-carotene about ninefold, blood lipids about threefold, fat intake about sixfold, and fiber intake about fivefold. This was crucial, as we primarily were concerned with comparing each county in China with every other county” (p. 74).

“The media called The China Study a ‘landmark study.’ ” It compared diets that were more or less based on plant-based foods, but all of which were significantly richer in plant-based foods than Western diets. Western studies, in contrast, had so far only compared different types of Western diets, that is diets based more or less on a relatively high proportion of animal protein.

Whereas in the West we primarily see diseases caused by excess, China has a higher incidence of diseases caused by poverty. These are quite different from cancer, diabetes, and coronary heart disease. And if they aren’t corrected, they lower life expectancy below that in the West.

CAMPBELL writes: “I have never pursued health hoping for immortality. Good health is about being able to fully enjoy the time we do have. It is about being as functional as possible throughout our entire lives and avoiding crippling, painful, and lengthy battles with disease” (p. 75).

Age-standardized comparisons of causes of death between industrialized countries and other countries show that coronary heart disease and breast cancer occur much more frequently in Western countries. The author calls these “Western diseases” diseases of affluence” and diseases of “nutritional extravagance” (p. 76).

Blood cholesterol comes from two main sources, the body’s own synthesis to covers its needs and animal-based foods. The blood cholesterol level is usually much lower with a diet that doesn’t include any animal-based foods. Cholesterol is also an excellent early indicator of coronary heart disease.

Cholesterol biosynthesis occurs mainly in the liver, but also in the intestines and skin (by eukaryotes) using simple starting materials. From Taschenatlas der Ernährung (Pocket atlas of nutrition) by Biesalski and Grimm:A low cholesterol intake, which can only be achieved by a strict diet regimen, lowers the dietary cholesterol portion of the overall cholesterol level quite considerably ... and constitutes ... only 10–15% of the daily cholesterol level. The plasma cholesterol levels and LDL receptors (responsible for the cellular uptake) remain in a steady state (equilibrium).

“In fact, a smaller part of the population (about 20–25%) reacts to a exogenous cholesterol supply pathologically.” The internal process of cholesterol homeostasis can no longer be maintained.

The average blood cholesterol level in China is 127 mg/dL and in the US, it is 215 mg/dL. In China, there are counties with high levels and others with very low levels. One county had an average of 94 mg/dL, and two groups of young women had levels of only 80 mg/dL. The US has been upholding the myth that levels below 150 mg/dL can lead to health problems!

In the counties in China, there was a strong correlation between cholesterol and disease rates: “As blood cholesterol levels decreased from 170 mg/dL to 90 mg/dL, cancers of the liver, rectum, colon, male lung, female lung, breast, childhood leukemia, adult leukemia, childhood brain, adult brain, stomach, and esophagus (throat) decreased.” ... “At the time of our study, the death rate from coronary heart disease was seventeen times higher among American men than rural Chinese men” (p. 78–79).

It is a known fact that higher blood cholesterol levels lead to coronary heart disease, but it is not so well known that this can also cause cancer. The three most renowned heart researchers and physicians Bill Castelli, Bill Roberts, and Caldwell Esselstyn Jr. confirmed Dr. COLIN CAMPBELL’s findings by stating that they had never seen a patient die of heart disease who had had blood cholesterol levels below 150 mg/dL. See also information on Wikipedia about cholesterol. “Dr. Castelli was the long-time director of the famous Framingham Heart Study of NIH; Dr. Esselstyn was a renowned surgeon at the Cleveland Clinic who did a remarkable study [on] reversing heart disease (chapter five); Dr. Roberts has long been editor of the prestigious medical journal Cardiology” (p. 79). (NIH stands for National Institutes of Health.) Castelli's study was a cohort study.

While saturated fats and dietary cholesterol also cause blood cholesterol to increase slightly, animal protein increases it dramatically. Plant-based foods, in contrast, contain no cholesterol and, in various other ways, help to decrease the amount of cholesterol made by the body.” ... “In rural China, animal protein intake (for the same individual) averages only 7.1 g/day whereas Americans average a whopping 70 g/day” (p. 80).

But even in China, where the protein intake is generally quite low, there are the same differences in areas with a higher consumption of animal-based products. However, these levels are still far below Western standards.

On the pages that follow, Dr. CAMPBELL explains the effect that fat has on our health. He describes the history of why we consume too much “bad” fat today. His conclusion: “The correlation between fat intake and animal protein intake is more than 90%” (p. 83).

Professor Ken Carroll, who taught at the University of Western Ontario in Canada, “showed a very impressive relationship between dietary fat and breast cancer.” He is also known for including immigrants in his studies to prove that cancer incidence cannot be explained by heredity. Sir Richard Doll and Sir Richard Peto of the University of Oxford (UK) “concluded that only 2–3% of all cancers could be attributed to genes” (p. 85).

There is an article on Ken Carroll (1923–1998) in the JN, The Journal of Nutrition. (He also helped to create the ChinesePod: Chinese Learning for Busy People.)

The average amount of fat consumed in China is 14.5% of the caloric intake, but does vary depending on the area from between 6–24%, while the average in the US is at 36%. In contrast to the US, the industry in China is not (yet) tinkering with the fat content of food. In China, fat comes primarily from animal products.

CAMPBELL also looks at menarche in young women and finds it to be between 15 and 19 years of age in China, with an average age of 17. The average age in the US is about 11 years! He lists out the resulting consequences and concludes that children should consume a diet that is low in animal-based foods, that is dairy and meat products. This is because there are great disadvantages to an early onset of menstruation. The author gives several reasons for this.

Finally, CAMPBELL addresses the importance of dietary fiber, which is found exclusively in plant-based foods. Fiber consists of highly complex carbohydrate molecules. It binds water and also attracts harmful chemical substances, similar to sticky tape. It reduces the caloric density of our food and creates a feeling of satiety.

Denis Parsons Burkitt, a specialist in tropical medicine at Trinity College in Dublin, published work on the benefits of fiber, for which he received the prestigious Bower Award. However, for almost 200 years, we have known that a low-fiber diet is associated with an increased risk of cancer, primarily breast and “intestinal” cancers.

Many experts claim that too much dietary fiber reduces iron absorption. However, the reverse was actually found in The China Study. Iron consumption in China is surprisingly high with 34 mg of iron per day as common high-fiber foods such as wheat and corn (but not polished rice) are also high in iron. In the United States, it is 18 mg/day.

Finally, the author discusses the importance of the many colors of fruit that come from antioxidants and their importance for our health. CAMPBELL describes the relationships and the reasons why plants, in particular, need to contain a great deal of antioxidants and how that affects us. He mentions, for example, various carotenoids, of which there are hundreds, such as beta-carotene in pumpkins, lycopene in tomatoes, and cryptoxanthin and ascorbic acid (vitamin C) in oranges. In this context, he lists out diseases that occur in areas with increased consumption of animal products: esophageal cancer, leukemia, and cancer of the nasopharynx, chest, stomach, liver, rectum, colon, and lung.

He also states that increased fruit consumption reduces heart disease, hypertensive heart disease, and strokes—thanks to the high amount of natural vitamin C (p. 94).

In the section titled “The Atkins Crisis,” CAMPBELL critically examines the Atkins diet and makes very good arguments against the diet. He debunks the “low-carb diet” that has become so popular as follows. According to a report that summarized the government food statistics, Americans consumed 13 pounds more fats and oils per person in 1997 than in 1970. In other words, fat consumption increased from 52.6 to 65.5 pounds. Because of the enormous increase in the total amount of food intake, the proportion in percent did decrease slightly. The reason for this increase in food intake is that Americans now eat more sugary junk food.

He calls statements in popular diet books either “severe ignorance or opportunistic deceit” (p. 95). These books are popular because people who eat a low-carb diet and a large portion of meat really do lose weight in the short term. This is not surprising as people on this diet reduce their calorie consumption from an average of 2,250 cal/day to only 1,450 cal/day.

However, the subjects on the Atkins diet complained of many side effects including 68% who complained of constipation, 63% of halitosis (bad breath), and 51% of headaches. In addition, the participants excreted 53% more calcium in their urine, which is a catastrophe for bone health.

The initial high loss of fluid is also very unhealthy. Australian scientists came to the following conclusion: “Complications such as heart arrhythmias, cardiac contractile function impairment, sudden death, osteoporosis, kidney damage, increased cancer risk, impairment of physical activity and lipid abnormalities can all be linked to long-term restriction of carbohydrates in the diet” (p. 97).

Atkins wrote in one passage that “many of them [the patients] take over thirty vitamin pills a day.” CAMPBELL concludes the section on Dr. Atkins as follows: “Perhaps it is a testament to the power of modern marketing savvy that an obese man with heart disease and high blood pressure became one of the richest snake oil salesmen ever to live, selling a diet that promises to help you lose weight, to keep your heart healthy and to normalize your blood pressure” (p. 97).

Of course, when it comes to carbohydrates, you have to distinguish between natural fruits, vegetables, and whole grains and highly refined simple and therefore harmful carbohydrates. In industrialized countries, people often primarily consume refined carbohydrates—which is the main problem. And then they eat iceberg lettuce, one of the vegetables with the least amount of nutrients.

The author states that our major sins are junk food containing a lot of fructose, pasta made with refined flour, potato chips, soda, sugary cereals, and low-fat candy bars.

He lists out differences between China and the United States such as, “Average calorie intake, per kilogram of body weight, was 30% higher among the least active Chinese than among average Americans. Yet, body weight was 20% lower” (p. 99).

He explains why a genetically determined “faster metabolism” is not the cause, but that this difference is the result of the different diet and greater activity in China. He mentions for example, how Chinese people ride their bikes to work. He is critical of the Chinese government for recommending a diet high in animal protein as a way to increase the body size of the Chinese, despite the fact that they have seen the results of The China Study. The country is welcoming the dairy industry and repeating the same mistakes that the West has made (p. 102).

Other problems that became evident during the studies were malnutrition, plant-based diets with insufficient variety and inadequate quality, parasitic diseases, childhood diseases, and tuberculosis—and this with a poor health care system.

Chronic infection with hepatitis B virus (HBV), in particular, was something that occurred often. In some areas, half of the people had a chronic infection, compared with 0.2–0.3% in the US. Liver cancer was therefore very common, but this again was mostly in areas with high casein or meat consumption—just like in the animal experiments!

His finding: casein, and very likely all animal proteins, may be the most relevant cancer-causing substances that we consume” (p. 104).

He often fought against the old theory of examining individual substances, such as the effect of selenium on breast cancer. We should approach this issue holistically. “Everything in food works together to create health or disease. The more we think that a single chemical characterizes a whole food, the more we stray into idiocy” (p. 106).

Here is another important statement from the author: “Sadly, it’s also ‘normal’ to have heart disease in America. Over the years, standards have been established that are consistent with what we see in the West. We too often have come to the view that US values are ‘normal’ because we have a tendency to believe that the Western experience is likely to be right” (p. 107).

CAMPBELL reports that he stopped eating meat 15 years ago, and later cut out almost all animal-based foods and that his blood cholesterol levels have improved although he has gotten older. He is physically fitter now than he was at age 25 and weighs 45 pounds less than he did at age 30—and he is now at an ideal weight for his height. As a child, he drank two quarts (almost 2 liters) of milk daily. He admits that he scoffed at vegetarians early on in his professional career.

Part II: Diseases of Affluence

In this part of the book, we learn specifics about individual diseases of affluence, which are also called lifestyle diseases. These are diseases triggered by lifestyle, behavior, and environmental factors that are prevalent in industrialized countries. The positive aspects of our current civilization, as far as health is concerned, are improved hygiene, medical advances in disease prevention (e.g., vaccinations), treatment possibilities (e.g., antibiotics), and a secure food supply.

Broken Hearts (p. 111)

CAMPBELL tells the reader that about 3,000 Americans suffer a heart attack each day. This is about the same number of people who died in the September 11, 2001, attack on the World Trade Center (WTC) (p. 111). And on page 123, he says that almost 2,000 Americans die from this disease each day. This information comes from a publication of the National Heart, Lung, and Blood Institute titled Morbidity and Mortality: 2002 Chart Book on Cardiovascular, Lung, and Blood Diseases.

As early as 1953, at the end of the Korean War, researchers studied 300 hearts of dead soldiers, who were all about 22 years old. They found that 77.3% of them had clear signs of heart disease. They had never suffered from or been diagnosed with a heart problem.

The author then explains the relationship between plaque (atherosclerosis) and collaterals, which the body forms to be able to somewhat maintain blood flow. About 15 the young men’s hearts had plaque that clogged 90% of an artery. But that isn’t usually the reason for a heart attack. “It turns out that it’s the less severe accumulations of plaque, blocking under 50% of the artery, that often cause heart attacks” (p. 113).

We then read important details about the Framingham Heart Study. It showed, for example, that men with cholesterol levels above 244 mg/dL suffer three times more heart attacks than men with values below 210 mg/dL.

We have our lipid levels tested. The results are listed in mmol/L. Cholesterol (T-Cho) should be <5.0, triglycerides (TG) <2.0, and HDL-cholesterol (HDL-c) >1.0. HDL is short for high density lipoprotein.

For total cholesterol, LDL or HDL, 100 mg/dL correspond to 2.6 mmol/L or vice versa 1 mmol/L would be 39 mg/dL. For triglycerides, the conversion is: 100 mg/dL corresponds to 1.1 mmol/L or 1 mmol/L corresponds to 88 mg/dL.

It has long been known that, for example, men of Japanese ancestry who live in Hawaii or California have much higher blood cholesterol levels than those who live in Japan. In 1946, Dr. Lester Morrison (Los Angeles) did a study of more than 100 people who had survived a heart attack. Half of them continued to eat their normal diet, and the other half reduced the amount of meat they ate significantly. Eight years later, 24% of the people in the first group were alive. But in the second group, 56% were still alive. After 12 years, every single person in the first group had died, but 38% of the second group was still alive.

A group of doctors in Northern California selected a large number of people with advanced heart disease and put them on a low-fat, low-cholesterol diet. They achieved a mortality rate four times lower than patients who did not participate.

It was determined “that eating plant protein has even greater power to lower cholesterol levels than reducing fat or cholesterol intake” (p. 119).

Despite these findings, the battle between representatives of the status quo and representatives of prevention through nutritional education continue. Surgery and drugs are used and considered important—but what about prevention? For decades, the establishment refused to accept any evidence about the effectiveness of diet changes and went so far as to negate it.

This occurred in spite of successful studies conducted by Dr. Caldwell B. Esselstyn Jr. at the treatment center for heart disease in Cleveland. He began his study in 1985 with 18 patients who combined had suffered 49 coronary events within the last eight years prior to the study. These included angina pectoris, bypass surgery, heart attacks (myocardial infarction), strokes, and angioplasty. At the beginning, their average cholesterol level was 246 mg/dL. Esselstyn saw his patients every 14 days, took blood samples, and did other tests, and also discussed the process. Soon the patients had an average cholesterol value of only 132 mg/dL. The LDL-cholesterol decreased dramatically. “In the following eleven years, there was exactly ONE coronary event among the eighteen patients who followed the diet. That one event was from a patient who strayed from the diet for two years. After straying, the patient consequently experienced clinical chest pain (angina) and then resumed a healthy plant-based diet. The patient eliminated his angina, and has not experienced any further event” (p. 127).

Seventy percent of Esselstyn’s patients experienced an opening of their previously clogged arteries. CAMPBELL includes images (angiography) of a patient’s coronary artery with arterial stenosis (narrowing) from before and after the diet program. These images show very clear differences (p. 128).

By 2003, all except one of the 18 patients were still alive, and after these 17 years had gone by, they were now all heading into their seventies and eighties.

Dr. Dean Ornish, a graduate of Harvard Medical School, had similar experiences. He treated 28 patients as part of his Lifestyle Heart Study, with solely a change in diet that excluded animal-based products except for one egg white and a cup of low-fat milk or yogurt a day, plus one hour of stress management daily and three hours of physical activity a week.

After one year, this group had a cholesterol level of 172 instead of the initial 227 mg/dL, and the LDL cholesterol level had dropped from 152 to 95 mg/dL. The frequency, duration, and severity of their chest pain (angina pectoris) had also decreased sharply. Not everyone stuck to the diet program strictly, but the best participants decreased their arterial blockages by more than 4%, while the group treated with conventional medicine had an increase of 8% in the blockages in their arteries within the same time period.

The group who participated experienced a 91% reduction in the frequency of chest pain, whereas the conventional group experienced a 165% increase (p. 130).

“As of 1998, almost 200 people had taken part in the Lifestyle Project, and the results are phenomenal. After one year of treatment, 65% of patients had eliminated their chest pain. The effect was long lasting, as well. After three years, over 60% of the patients continued reporting no chest pain” (p. 131).

CAMPBELL points out that 35% of all heart attacks happen to Americans with a cholesterol level between 150 and 200 mg/dL. This means that 65% have levels higher than 200 mg/dL, or 5.2 mmol/L and above. A truly safe cholesterol level is below 150 mg/dL or 3.9 mmol/L. The total fat intake should be no more than 10% of the total calories.

Obesity (p. 135)

The next problem with our Western diet is that it causes us to gain weight. A person with a BMI greater than 25 is considered overweight and with a BMI greater than 30 obese. Approximately 15% of children and adolescents in the US between the ages of 6 and 19 are overweight or obese and “another 15% are at risk of becoming overweight” (p. 136).

CAMPBELL describes the consequences for adults, the things they may not be able to do because they are overweight or obese. He also points out that medical care costs related to obesity came to $70 billion in 1999 and rose to $100 billion by 2002, just 3 years later. The $30–40 billion dollars spent on preventative measures (special diet plans and pills) is not even included.

He cites studies showing that vegetarians and vegans weigh on average of 5 to 30 pounds (2.3 to 13.6 kg) less. An independent intervention study encouraged obese participants to eat as much food that was low-fat, whole-food, and plant-based as they liked. These people lost an average of 16 pounds (7.7 kg) within three weeks. At the Pritikin Center, 4,500 patients achieved similar results. They lost 5.5% of their body weight (p. 139).

Another long-term study resulted in an average weight loss of 24 pounds (11 kg) after one year. But these reductions will not occur if a large percentage of your diet consists of sweets, pasta, baked goods, and the like. The author writes:

“Some people become vegetarian only to replace meat with dairy foods, added oils and refined carbohydrates, including pasta made with refined grains, sweets and pastries. I refer to these people as ‘junk-food vegetarians’ because they are not consuming a nutritious diet” (p. 140).

The author also discusses the importance of regular physical activity and thermogenesis, which is the production of body heat. He observes that “vegetarians … have a slightly higher rate of metabolism during rest, meaning they burn up slightly more of their ingested calories as body heat rather than depositing them as body fat” (p. 142). He does not say that natural vegetarian food would be harder to digest.

Diabetes (p. 145)

The author explains differences between type 1 diabetes, when the body no longer produces the proper amount of insulin, and type 2, when there is enough insulin but the cells no longer respond appropriately to it. This is called insulin resistance. In the US, diabetes costs come to $130 billion a year.

He goes on to describe the complications that arise because of diabetes such as heart disease with two to four times the risk of death, strokes, high blood pressure, blindness, kidney diseases, nervous system disorders, and increased susceptibility to other diseases. Seventy percent of people with diabetes also have high blood pressure.

A graph from H. P. Himsworth shows the relationship between diet and death rate due to diabetes at around 1925, a time when today’s treatment methods didn’t yet exist. It clearly demonstrates: “As carbohydrate intake goes up and fat intake goes down, the number of deaths from diabetes plummets from 20.4 to 2.9 per 100,000 people” (p. 149).

CAMPBELL describes several studies that all point in the same direction: less animal-based food equals less diabetes. This is difficult to imagine. Studies in England and Wales during the war and immediately thereafter, from 1940 to 1950, demonstrate the same pattern. Since people were eating fewer animal-based foods during this time, the rate of diabetes dropped significantly.

He next looks at a study conducted by physician Dr. James Anderson. In this study, he used only dietary means to treat 25 type 1 diabetics and 25 type 2 diabetics who had to take insulin shots. “After just three weeks, the Type 1 diabetic patients were able to lower their insulin medication by an average of 40%” (p. 152). And their cholesterol levels also decreased by 30%.

Of the type 2 patients who ate this high-fiber, low-fat diet, 24 of the 25 were able to discontinue their insulin medication! This included a man who had suffered from this disease for 21 years and previously was taking 35 units of insulin daily. The Pritikin Center achieved similar results: “Of forty patients on medication at the start of the program, thirty-four were able to discontinue all medication after only twenty-six days” (p. 152).

A later study examined groups with elevated blood sugar levels, which is a precursor to diabetes. One group received metformin and diet guidelines, and the other group participated in intensive lifestyle counseling that included an exercise program. After three years, the metformin group had 31% fewer cases of diabetes than the placebo group. Both groups followed the same standard dietary guidelines. However, the lifestyle group had an astounding 58% fewer cases of diabetes. In addition, this group also benefited in terms of improving other health problems.

Common Cancers: Breast, Prostate, Large Bowel (p. 157)

CAMPBELL discusses breast cancer first. He goes over the genetic risk factors BRCA1 and BRCA2 and the greater impact one’s lifestyle has. He states that if the problem is recognized earlier, that this doesn’t automatically mean a prolongation of life. He summarizes several studies, some of which suggest that the anti-estrogen tamoxifen can prevent the occurrence of breast cancer. However, European studies have denied any statistically significant benefit of tamoxifen, and instead stress the risk of stroke, uterine cancer, cataracts, deep vein thrombosis, and pulmonary embolism.

Even just a moderate change in diet brings greater benefits: “Using diet as an effective treatment of already-diagnosed disease has been well documented in human studies with advanced heart disease, clinically documented Type 2 diabetes (see chapter seven), advanced melanoma (a deadly skin cancer) and, in experimental animal studies, liver cancer” (p. 165).

Our body can transform and excrete environmental toxins such as PAHs (polycyclic aromatic hydrocarbons), but this “is very much controlled by what we eat” (p. 166). The right kinds of food prevent the PAHs from binding to our DNA and causing damage.

The author describes the various correlations with respect to breast cancer risk and also addresses the subject of hormone replacement therapy (HRT). He believes that it does more damage than good. He explains five reasons for this.

It is known that colorectal cancer, including rectal cancer, is very different from culture to culture. Previously, genetic differences were thought to be the cause. But today science recognizes lifestyle as the actual cause. The China Study also strongly confirms this. Thirty years ago, a comprehensive study was conducted in 32 countries (Ferlay J, Bray F, Pisani P, et al.) that showed a major link between colon cancer and meat consumption. Denis Parsons Burkitt also believes that consuming enough dietary fiber is also essential for general digestive health. And fiber is only found in plant-based foods (p. 170)—and much less in processed foods made from plants.

We read about different study results including those of the EPIC study, which is based on data from over 519,000 people from Europe, and a study of white South Africans (European Prospective Investigation into Cancer and Nutrition). The best results are achieved from leafy and fruit-like vegetables, less so from root vegetables. Animal-based foods definitely have the most unfavorable effect.

Amazing for Wikipedia:

“Participants with a high BMI died more frequently from cancer or cardiovascular disease than participants with a moderate BMI. Participants with a low BMI, however, died more frequently from diseases of the respiratory system.” ...

“In March 2013, Rohrman et al. published an analysis of the EPIC data (full text) that examined the relationship between the consumption of red meat, processed meat, and poultry and the risk of premature death. The researchers analyzed data from a total of 448,568 men and women who were not suffering from cancer at the beginning of the study and also had not had a stroke or heart attack. Information on each participant was recorded, including how much they ate, how much they exercised, whether they smoked, and what their body mass index was. At the beginning of the study, all participants were between 35 and 69 years old. They came from ten European countries and on average were part of the study for 12.7 years. A total of 26,344 participants died during this period. The analysis showed that the consumption of processed meat (e.g., sausage) had a significant statistical correlation with a higher mortality rate. The participants who consumed more than 160 grams of processed meat daily had a 44 percent higher risk of dying during the study period than those who consumed only about 20 grams per day” (Wikipedia, German version).

“The maxim of ‘fruit and vegetables 5 times a day’ (5 A Day), which was recommended years ago, is based on desirable health policy assumptions, but lacked a scientific basis.” Professor CAMPBELL had a similar suggestion—if meat consumption was at the same time more than 10% of the protein in one’s diet.

And other factors did enter into the study. Calcium was demonstrated to inhibit the growth of critical cells in the colon and bind intestinal bile acid. This is a statement that the dairy industry likes to use to justify their claim that it is necessary to drink milk. The truth is: “The parts of the world that consume the most calcium, that is Europe and North America, have the highest rates of colorectal cancer” (p. 175). Physical exercise is also effective in providing protection against colon cancer.

The author recommends a colonoscopy every 5 to 10 years starting at 50 and for at-risk patients starting at age 40. Genetic predisposition to colorectal cancer is effective for only 1 to 3 percent, but previous incidence in the family is more significant. Family members also tend to have similar eating habits.

Regarding prostate cancer, the author explains that about half of all men over 70 have latent prostate cancer. But only 7% of those diagnosed with prostate cancer die within five years. He confirms that nutrition plays a key role as to whether prostate cancer develops or not. “Surprisingly, one of the most consistent, specific links between diet and prostate cancer has been dairy consumption. A 2001 Harvard review of the research could hardly be more convincing” (p.186).

In these studies, men with the highest consumption of dairy products had up to a fourfold increased risk for metastatic or fatal prostate cancer in comparison to those who had a low consumption of dairy products. “Let’s consider that again: dairy intake is ‘one of the most consistent dietary predictors for prostate cancer in the published literature’ ” (p. 178).

CAMPBELL believes the reason to be mainly the Insulin-Like Growth Factor 1 (IGF-1). Under unhealthy conditions, it directly increases the division rate and growth of new cells. He references seven studies that have demonstrated this. High IGF-1 levels and low blood levels of a particular protein cause men to “have 9.5 times the risk of advanced-stage prostate cancer” (p. 179). According to various studies, the human body produces more IGF-1 when we eat more animal-based foods such as meat and dairy products.

Animal protein and calcium contained in cow’s milk also block the formation of vitamin D in the body.

The author explains: “The widespread communities of nutrition professionals, researchers, and doctors are, as a whole, either unaware of this evidence or reluctant to share it. Because of these failings, Americans are being cheated out of information that could save their lives” (p. 182).

Autoimmune Diseases (p. 183)

In this group of diseases, the body systematically attacks itself. This is difficult to treat, and the result is a progressive loss of physical and mental function. The author lists out 17 autoimmune diseases, including multiple sclerosis (MS), type 1 diabetes, rheumatoid arthritis, thyroid disorders (such as Graves’ disease), vitiligo, and pernicious anemia due to type A gastritis.

The author explains that the immune system is a system and not an organ. It is like a military network that exists to ward off foreign invaders. He then explains its individual parts, their function, and how they work. The white blood cells formed from stem cells in the bone marrow (leukocytes) are called B-cells (bones). In addition, immature cells migrate to the thymus, which specializes them as needed. These are called T-helper cells. Foreign invaders, such as viruses and bacteria, are protein molecules called antigens. The body develops a kind of “mirror image” protein that fits perfectly onto the antigen and destroys it. The mirror image protein is called a receptor protein.

“During the process of digestion, for example, some proteins slip into our bloodstream from the intestine without being fully broken down into their amino acid parts. ... One of the foods that supply many of the foreign proteins that mimic our own body proteins is cow’s milk” (p. 186).

Concerning type 1 diabetes CAMPBELL writes: “What most people don’t know, though, is that there is strong evidence that this disease is linked to diet and, more specifically, to dairy products. The ability of cow’s milk protein to initiate Type 1 diabetes is well documented.” Here, he cites three reports (p. 187).

He then explains in eight steps what can happen when a baby isn’t nursed long enough and is instead fed cow’s milk proteins (such as in infant formula) and quotes from one of the reports: “cow’s milk may cause one of the most devastating diseases that can befall a child” (p. 187).

A 1992 study demonstrated how incompletely digested cow’s milk protein called bovine serum albumin (BSA) can bring the antibody levels above 3.55 if type 1 diabetes is present—all other children had values below that.

CAMPBELL explains why genes don’t work in isolation but instead need a trigger to produce effects. Other researchers came to the same conclusions after observing identical twins.

“Cow’s milk consumption by children zero to fourteen years of age in twelve countries shows an almost perfect correlation with Type 1 diabetes. The greater the consumption of cow’s milk, the greater the prevalence of Type 1 diabetes. In Finland, Type 1 diabetes is thirty-six times more common than in Japan” (p. 190).

Two well-known studies conducted in Finland that began in the late 1980s and mid-1990s prove this point. One of them even shows “that cow’s milk consumption increases the risk of Type 1 diabetes five- to sixfold.” The second study shows that milk increases the development of at least three other antibodies in addition to the ones previously discussed in the book. 

The author lists numerous proofs and examples that clearly show the significant connection established between the consumption of milk and dairy products and various diseases. But he knows that the industry will make sure that these findings don’t find their way into doctors’ offices. That would put the existence of the industry at risk. The huge budget for PR, marketing, and direct manipulation facilitates the industry’s endeavors. Meanwhile, the incidence of type 1 diabetes increases by 3% each year (p. 191).

The very powerful tobaccoindustry used controversies for decades to make sure that the harmfulness of cigarettes wasn’t discovered, and today, the dairy industry is doing much the same thing and having just as much success. It learned from war how to completely obscure a hazard. An umpteen number of studies exist that are designed to obtain different results. And with the media’s marketing power, these results can also be easily spread. In contrast, reliable scientific studies rarely make their way into politics or to the consumer. How could they?

Next, we read about multiple sclerosis (MS). The author explains the effects of the disease and that MS is 100 times more frequent in the northern climates than at the equator. Dr. Roy Swank, who conducted research in Norway and then at the Montreal Neurological Institute, was the first well-known researcher to study the effect of diet on the progression of MS.

Dr. Swank conducted a trial on 144 MS patients and kept records on them for the next thirty-four years. “He summarized his work in 1990, concluding that for the sub-group of patients who began the low-saturated fat diet during the earlier stages of their disease, ‘about 95% ... remained only mildly disabled for approximately thirty years.’ Only 5% of these patients died. In contrast, 80% of the patients with early stage MS who consumed the ‘poor’ diet (higher saturated fat) died of MS (pp. 195 and 196).

Success stories like these about people’s experiences eating a diet with as little animal protein as possible do not usually appear on Wikipedia. The results are probably better than with drugs, but people don’t have to buy any products to get these results and therefore don’t have a lobby.

In recent years, numerous studies have confirmed Dr. Swank’s results. If this were a medication, the company producing it would now be making billions in sales, says CAMPBELL. James Anderson, mentioned above, also practiced diet therapy successfully.

Researchers believe there is much less incidence of MS in the far northern coastal areas, where there is a high level of fish consumption, because of the consumption of omega-3 fatty acids. The people in those areas also consume far fewer dairy products, which, however, is not mentioned.

Websites to help people with MS do not address the fact that dairy products are the biggest problem for MS patients. ...

We consider regular eating habits and common lifestyle diseases to be “normal.” Healthy eating habits, on the other hand, are thought to be weird—only exercise is considered healthy.

Wide-Ranging Effects: Bone, Kidney, Eye, and Brain Diseases (p. 203)

CAMPBELL tries to get us to seriously consider the very significant correlations between plant-based food and good health versus animal-based products and lifestyle diseases by discussing an overwhelming diversity and number of studies conducted by other researchers. You can support virtually any viewpoint with an individual study, but when thousands of scientific studies show that a predominantly plant-based diet leads to better health, people should pay attention.

In regards to osteoporosis, he shows that regions where people consume more cow’s milk and dairy products also have a greater incidence of osteoporosis and vice versa. American women over 50, for example, have one of the highest rates of hip fractures in the world. Some European countries, Australia, and New Zealand consume more dairy products and have even higher rates!

An example of how the dairy industry manipulates the information available is the following entry on the German Wikipedia site from February 2014:

Adequate calcium intake (about 1 g/day) contributes significantly to prevention (basic therapy, DVODachverband Osteologie e.V., [German umbrella organization for osteology]). One gram of calcium is contained in one liter of milk or 100 g of hard cheese. In addition to dairy products (in this case, milk and yogurt in particular), green vegetables such as kale and broccoli are especially good calcium suppliers. People who do not drink milk or eat cheese should take 800 mg of calcium in tablet form daily.

This is typical for German Wikipedia and does not appear in the English version, where they advise against taking tablets.

“As of 2013, there is insufficient evidence to determine if supplementation with calcium and vitamin D results in greater harm or benefit in men and premenopausal women. Low dose supplementation (less than 1 g of calcium and 400 IU of vitamin D) is not recommended in postmenopausal women as there does not appear to be a difference in fracture risk. It is unknown what effect higher doses have. There however may be some benefit for the frail elderly living in nursing homes.

While vitamin D supplementation alone does not prevent fractures, combined with calcium it might. There is, however, an increased risk of myocardial infarctions and kidney stones. Vitamin K supplementation may reduce the risk of fractures in postmenopausal women; however, there is no evidence for men.”

The fact that animal protein results in excess acid in the body has been known since the 1880s and was documented in 1920. But the body keeps the pH in the blood very constant at a pH of 7.36 to 7.44. It uses calcium as a very effective base to neutralize the acid. Since the calcium must come from somewhere, it is pulled out of the bones, which, in turn, weakens the bones enormously.

This can lead to calcium excretion in the urine. The author gives summaries of studies conducted in 1974, 1981, and 1990. These demonstrate that an increase in protein intake of 35 to 78 g per day leads to an alarming 50% increase of calcium excretion in the urine. This was shown in a study conducted by the Atkins Center.

On page 207, the author provides an impressive graph that shows the relationship between the intake of animal-based protein versus plant-based protein and hip fractures in different countries. Hip fracture incidence increases from virtually zero to 200 per 100,000 persons a year. See also alkaline diet.

CAMPBELL goes over the work conducted by Harvard professor Mark Hegsted and explains the body’s mechanisms that regulate calcium and calcitriol and how this ability becomes impaired if high levels of calcium are consumed over a long period of time. This is virtually a guarantee for osteoporosis, and yet doctors still recommend that their patients consume more milk. In addition, milk has a relatively high level of phosphorus, which also negatively affects the body.

The author states that “there are some devilishly contradictory and confusing details in this great circus of osteoporosis research,” and lists out six facts related to the topic. Ultimately, though, these studies show that a “much better, predictor of osteoporosis is the dietary ratio of animal-to-plant protein” (p. 210).

He then gives some other advice on how to decrease your risk of osteoporosis: “Plenty of calcium is available in a wide range of plant foods, including beans and leafy vegetables. As long as you stay away from refined carbohydrates, like sugary cereals, candies, plain pastas, and white breads, you should have no problem with calcium deficiency” (p. 211). In this case, he is speaking to people who live exclusively or almost vegan. In addition, he mentions that excessive salt consumption can be a problem.

Animal-based products are also a burden on the kidneys. Professor W.G. Robertson from the Medical Research Council in Leeds is one of the world’s foremost experts on diet and kidney stones, and a research group of his has investigated the relationship between food and kidney stones more closely. The most impressive graph from his research can be found on page 213. Two other graphs show the effect animal protein has on calcium and oxalate in the urine.

Note from Wikipedia: “Since oxalic acid and its salts bind with calcium (needed for bone structure) to form insoluble salts, the body can eliminate it only very slowly. We should therefore consume oxalic acid and its salts only in small doses. Oxalic acid is also present in chocolate, nuts, cocoa powder, spinach, and rhubarb.”

CAMPBELL next discusses a variety of eye problems. What we eat at meals primarily has an effect on cataract (clouding of the lens in the eye) and macular degeneration. Millions of older Americans suffer from diseases such as these.

Cataract surgery, in particular, is common for people age 70 and up. It’s a fairly simple procedure today, but macular degeneration is incurable and progressively and slowly leads to blindness. It begins with a yellow spot at the site of the retina, where the eye sees best—and continues with a gradual loss of function.

Antioxidants from fruits and vegetables can play a significant role in preventing this disease. The author explains the relationships involved and discusses two authoritative studies. “The findings of these two studies suggested that as much as 70–88% of blindness caused by macular degeneration could be prevented if the right foods are eaten” (p. 215).

Five eye care centers worked together with 356 people between the ages of 55 and 80 to study advanced macular degeneration. The study showed that “five out of six plant-based foods measured also were associated with lower rates of macular degeneration (broccoli, carrots, spinach or collard greens, winter squash and sweet potato). Spinach or kale conferred the most protection” (p. 215). Study participants who consumed a lot of carotenoids with these foods had 43% less disease than the group with a low intake of plant-based foods.

“There was 88% less disease for people who ate these greens five or more times per week when compared with people who consumed these greens less than once per month. The only food group not showing a preventive effect was the cabbage/cauliflower/brussels sprout group, which sports the least color of the six food groups” (p. 215).

In a review of the five carotenoids in food, those from dark green leafy vegetables showed the highest protective effects. “In contrast, supplements of a few vitamins, including retinol (preformed ‘vitamin’ A), vitamin C and vitamin E showed little or no beneficial effects” (p. 216).

The second study compared 421 patients suffering from macular degeneration with 615 people that did not have the disease. The researchers measured the levels of antioxidants in the blood instead of the levels of antioxidants consumed and came to similar conclusions. The reduction was about 65–70%. In this case as well, carotenoids had statistically significant results while selenium and specific vitamins did not.

People who consumed more dark green leafy vegetables also had 40% less cataracts. This is based on a study of 1,300 people conducted from 1988 to 1998. The researchers found that the people who consumed more lutein had a lower rate of cataracts. And this makes sense since lutein is a major component of the lens tissue in the eye. The carotenoid zeaxanthin is also a key factor.

Old age is often accompanied by a slowly decreasing ability to remember and think. Some people, however, develop dementia, which ultimately becomes a life-threatening mental disorder. This includes vascular dementia, a disease caused by multiple small brain strokes and Alzheimer's disease. Alzheimer’s disease is about four times more common. With Alzheimer’s, the protein amyloid beta accumulates in important parts of the brain as a plaque.

The German Wikipedia entry discusses genetic predisposition, but also describes the following: “There are also food-related risk factors such as cholesterol level. When there is a lack of cholesterol, amyloid beta peptides do not form in vitro. This may have to do with the fact that Aβ (amyloid beta) production occurs exclusively in lipid rafts of the cell membrane, and that these structures contain high levels of cholesterol.”

“However, there also seem to be other risk factors involved. Several drugs (medications) increase Aβ42 production to dangerous levels in vitro and in a mouse model. Specific inhibitors of cyclooxygenase 2 and certain isoprenoids are suspect.”

CAMPBELL continues: “Alzheimer’s is surprisingly common. It is said that 1% of people at age sixty-five have evidence of Alzheimer’s, a figure that doubles every five years thereafter” (p. 218). People with cognitive impairments have a tenfold risk for Alzheimer’s—but also develop more cardiovascular diseases, strokes, and type 2 diabetes. Hypertension (high blood pressure) and elevated blood cholesterol levels are considered risk factors. Both are influenced by diet, as is the third factor, free radicals.

“Animal-based foods lack antioxidant shields and tend to activate free radical production and cell damage, while plant-based foods, with their abundant antioxidants, tend to prevent such damage” (p. 219).

Studies on children of people who, for example, left Africa or Japan and adopted the Western lifestyle, clearly demonstrate that lifestyle is much more important than genetic predisposition.

In practice, new studies are constantly appearing that focus on specific food components such as vitamin E or beta-carotene. But people often forget that the “great orchestra of nature” functions a certain way and a single instrument by itself cannot counter that. Sometimes, this is unavoidable, but in other circumstances, this manner of research is foolish and has no practical relevance.

The Framingham Study showed, for example, “that for every three additional servings of fruits and vegetables a day, the risk of stroke will be reduced by 22%” (p. 220). The author reasons that with a radical change in diet the risk reduction can get close to 100%.

He describes a large number of studies that, for example, also showed that low homocysteine levels and high folic acid levels are desirable.

He further describes how friends and people he grew up with often said that they considered him to be a health nut and that they would eat a steak whenever they wanted to, and smoke, and do whatever else they wanted. Some of them have already died, while others are living in nursing homes. The author himself is about 80 years old (born in 1934) and is still enjoying the benefits of having a healthy and strong body.

Part III: The Good Nutrition Guide

The author stresses the negative effects of the low-carb Atkins diet and its successor the South Beach Diet, which was developed by Dr. Arthur Agatston. When CAMPBELL was at a restaurant one day, he saw Pasta Primavera, a huge portion of noodles with vegetables, listed as a “low-carb dish” on the menu. This dish consists almost entirely of carbohydrates “of the bad kind” and just a few of “the good kind” from the vegetables.

The fact that chefs can’t even distinguish between low-carb and high-carb dishes shows just how great the confusion must be. The South Beach Diet is actually the regular American diet, which is successfully being sold as a healthy option, but which in fact is a “toxic diet that has been shown to make us fat, give us heart disease, destroy our kidneys, make us blind and lead us to Alzheimer’s, cancer and a host of other medical problems” (p. 224).

CAMPBELL shares two common adages with readers: “Americans love hogwash” and “Americans love to hear good things about their bad habits” (p. 224).

“Very little of the nutrition information that makes it to the public consciousness is soundly based in science, and we pay a grave price. One day olive oil is terrible, the next it is heart healthy. One day eggs will clog your arteries, the next they are a good source of protein. One day potatoes and rice are great, the next they are the gravest threats to your weight you will ever face” (p. 224).

Eating Right: Eight Principles of Food and Health (p. 225)

Drs. CAMPBELL begin this chapter with 20 reasons why you should choose a healthy lifestyle. And who of us who are 50 or older don’t want to look younger, feel younger, have more energy, and avoid impotence for as long as possible? But we can achieve even more with a better lifestyle.

His eight principles are as follows:

1. Nutrition represents the combined activities of countless food substances. The whole is greater than the sum of its parts.

They explain how the body absorbs food, which already begins in the mouth. As an example, he provides a table showing all of the nutrients contained in spinach. These include 9 vitamins, 8 fatty acids, and 18 amino acids. They also include the fact that spinach contains many types of phytosterols.

2. Vitamin supplements are not a panacea for good health.

“Because nutrition operates as an infinitely complex biochemical system involving thousands of chemicals and thousands of effects on your health, it makes little or no sense that isolated nutrients taken as supplements can substitute for whole foods. Supplements will not lead to long-lasting health and may cause unforeseen side effects” (p. 228).

Nevertheless, interest in dietary supplements has become a huge business in recent years. It provides lucrative opportunities for disinformation. For example, a large-scale study conducted from 1994 to 1996 showed that beta-carotene does not decrease lung cancer as expected, and instead users developed more lung cancer after four to eight years.

3. There are virtually no nutrients in animal-based foods that are not better provided by plants.

A table is included that compares a number of plant-based foods with animal-based foods. It clearly shows the great superiority of plant-based foods. Readers can see for themselves that plant-based foods contain about the same amount of protein but about 10 times less fat. In addition, plant-based foods contain a lot more of the other nutrients, sometimes up to ten times more. Meat contains zero dietary fiber. And the authors also address the problem of vitamin B12 (cobalamin). They point out that people who are eating a vegan diet should take vitamin B12  supplements or eat foods that are enriched with vitamin B12. Depending on a person’s geographical location and/or lifestyle, the authors make the same recommendation for vitamin D.

A reference for this is Mozafar A. “Enrichment of some B-vitamins in plants with application of organic fertilizers.” Plant and Soil 167 (1994) 305–311.

However, I believe CAMPBELL is mistaken with the following statement: “Research has convincingly shown that plants grown in healthy soil that has a good concentration of vitamin B12 will readily absorb this nutrient. However, plants grown in ‘lifeless’ soil (non-organic soil) may be deficient in vitamin B12” (p. 232).

At this time there is no separation of the analogs. The German Wikipedia entry says the following: “Some vegetables preserved through lactic fermentationsome types of algae and legumes (e.g., peasbeans, and lupines), and also zingiberales such as ginger contain some B12 coenzymes, if only in very small amounts. And a few types of edible mushrooms, especially button mushrooms, are also said to contain small amounts of vitamin B12.”

Under the term cobalamins, the German Wikipedia entry still lists about the same amount of B12 for spirulina and calf’s liver (57 µg). If this were true, 10 g of spirulina daily would be all you would need. However, spirulina also contains B12 analogs that can even decrease vitamin B12 absorption. Nori is listed as having 15 µg. I have not yet completed my research in this area.

4. Genes do not determine disease on their own. Genes function only by being activated, or expressed, and nutrition plays a critical role in determining which genes, good and bad, are expressed.

Once again, Drs. CAMPBELL emphasize the fact that dormant genes do not have any effect on our health. The environment, particularly one’s diet, activates or deactivates genes. (EE: And that leads to gene regulationepigenetics, and heredity).

5. Nutrition can substantially control the adverse effects of noxious chemicals.

The authors describe the commotion that occurred in 2002 over acrylamide in cooked potatoes, which acts as a carcinogen. But according to Maillard, a potato treated with high temperatures has at least 450 such Maillard reactions that cause inflammation in the cells. They include an interesting section on gene expression. “We do not want to hear that our favorite foods are a problem simply because of their nutritional content” (p. 236).

6. The same nutrition that prevents disease in its early stages (before diagnosis) can also halt or reverse disease in its later stages (after diagnosis).

“In humans, we have seen research findings showing that a whole food, plant-based diet reverses advanced heart disease, helps obese people lose weight, and helps diabetics get off their medication and return to a more normal, pre-diabetes life. Research has also shown that advanced melanoma, the deadly form of skin cancer, might be attenuated or reversed by lifestyle changes” (p. 237).

In 1978 I got to meet the wife of a vegan raw foodist. I was at the Bircher-Benner clinic at the time and refused the cooked anticancer meals served there. Instead, I requested vegan raw food, and the chef was very happy to prepare these meals for me. I wanted to know why. After all, this meant overtime for him.

He actually invited me to his home and introduced me to his family. I found out that they had changed to a vegan raw food diet five years before because his wife had suffered from malignant melanoma with numerous metastases. She seemed to be in her mid-twenties. Cancer at this stage almost always ends in death within a few months. But she had cured herself by making the radical and permanent change to an exclusively vegan raw food diet. Later, I met a 35-year-old Austrian, who had also cured himself from cancer. At least, the doctors couldn’t find any signs of the cancer in his blood. But after he had just barely recovered, he reverted back to his previous eating habits and died a little over a year later, just as I had expected. The same type of cancer had come back.

The woman mentioned above definitely remained healthy. And so did I, after healing myself from mantle cell lymphoma stage 3a, which at least back then was incurable. Today, bone marrow transplants offer a small chance of survival.

7. Nutrition that is truly beneficial for one chronic disease will support health across the board.

We learn again that a healthy diet prevents all types of diseases; it is not selective. This actually seems self-evident, but even the editor of a publishing house for the topic said that a separate diet plan for each disease would sell better and be more marketable.

8. Good nutrition creates health in all areas of our existence. All parts are interconnected.

“The process of eating is perhaps the most intimate encounter we have with our world; it is a process in which what we eat becomes part of our body. ... people have more energy when they eat well. This synergy between nutrition and physical activity is extremely important, and is evidence that these two parts of life are not isolated from each other. Good nutrition and regular exercise combine to offer more health per person than the sum of each part alone. We also know that physical activity has an effect on emotional and mental well-being” (pp. 238–239).

How to Eat (p. 241)

CAMPBELL opposes deprivation and complex weight loss plans that usually only lead to a yo-yo effect. He writes, “My advice is to try to eliminate all animal-based products from your diet, but not obsess over it” (p. 242). However, this requires a radical change in your thinking. Cutting out only some animal-based products simply takes more work. He believes that a radical change for just one month, to try it out, is much better. “Give it one month. You’ve been eating cheeseburgers your whole life; a month without them won’t kill you” (p. 244).

I personally think that it takes three months—without any exceptions—it is only then that your sense of taste has truly changed. You can find the same time span (in relation to salt) in the book review on Salt Sugar Fat by Michael Moss and certainly in the book itself. He recommends having a blood test done before and after.

CAMPBELL emphasizes the fact that the large number of plant-based foods and herbs and spices available make it possible for you to have a varied and tasty diet—even without pasta and baked goods.

When you switch to eating a lot of raw foods, your digestive tract will have to adapt. You should not expect support from your family, friends, and colleagues because many people perceive it as threatening when someone they know eats a vegetarian or even vegan diet.

One of CAMPBELL’s associates gives numerous tips to help you make the change, such as buying cookbooks with interesting and easy-to-make menus and asking friends and families for good recipes. The associate’s sister, for example, gave him a delicious recipe for West African peanut stew.

There are dozens of herbs and spices that you can use to cook and prepare your food.

And then your vegan food will be very tasty. Wikipedia lists a large number of culinary herbs and spices here.

Even restaurants rarely prepare rich and tasty vegetable dishes. When I do eat cooked food, it has been my experience that the dishes prepared at restaurants are often too salty—unless the chef is given special instructions.

Part IV: Why Haven't You Heard This Before? 

People who are new to this subject often wonder why they generally have heard the opposite: that milk and meat are practically the best types of food. The author explains why and begins with this statement: “As you will come to see, much is governed by the Golden Rule: he who has the gold makes the rules. There are powerful, influential and enormously wealthy industries that stand to lose a vast amount of money if Americans start shifting to a plant-based diet” (p. 249).

CAMPBELL doesn’t believe that the industry pays scientists to “cook the data” or conduct other illegal activities. However, he writes, “The entire system—government, science, medicine, industry and media—promotes profits over health, technology over food and confusion over clarity” (p. 250).

Science - The Dark Side (p. 251)

The author first explains how great the need is for people with advanced cancer and how by the end of the 1970s, Americans were spending a billion dollars a year for various “miracle cures.” He then describes how myths are kept alive such as in the case of the supposed “miracle cure” called Laetrile (also known as amygdalin), which was touted to be a newly discovered vitamin (B17). There was, of course, no scientific basis for this—only commercial reasons.

The link above to amygdalin includes additional information. Sensational books have been published on amygdalin for decades, such as Vitamin B17 Die Revolution in der Krebsmedizin (Vitamin B17, the revolution in cancer therapy), which have proven to be unfounded. In this context, CAMPBELL also mentions pangamic acid, which was initially called vitamin B15. However, the body can produce both of these substances in sufficient quantities. Both are marketed strictly for commercial reasons or, at best, faith. They are good examples for the subject at hand. This issue is covered in the book on page 252.

Dr. COLIN CAMPBELL outlines the positions he has held in various organizations, societies, and committees. For example, he worked with the Federation of American Societies for Experimental Biology and Medicine, FASEB, which now has 26 member organizations and at that time included more than 20,000 scientists. He also worked for two of its member organizations, in societies on nutrition and pharmacology. CAMPBELL was especially active in the late 1970s at the American Institute of Nutrition, now called American Society of Nutritional Sciences (ASN).

On the following pages, he describes what he experienced there and how things work in this world of its own. His “principle work was to chair, under contract to the Food and Drug Administration, a committee of scientists investigating potential hazards of using nutrient supplements” (p. 253). There was a dispute at the time regarding what “eating right” really meant. The industry wanted to expose the McGovern Report from 1977 as a fraud. For this report, Senator George McGovern, a Vietnam War opponent, had led a committee to establish a healthy eating plan.

“Within the scientific community it was widely known that the NAS [National Academy of Sciences] Food and Nutrition Board was strongly influenced by the meat, dairy and egg industries” (p. 255).

CAMPBELL was the only one of the 18 committee members who had no connections to the commercial food and pharmaceutical industries and their coalitions.

Some of his colleagues “enjoyed handsome benefits, including first-class travel expenses and nice consulting fees, paid by animal foods companies” (p. 256).

He compares this situation with the problem of cigarettes and health. “When scientific evidence first emerged to show that cigarettes were dangerous, there were hordes of health professionals who vigorously defended smoking” (p. 256).

The United States has a large number of organizations that provide information about nutrition, and some of them have huge budgets. Could this be the reason that the US has the worst diet when compared to other countries? CAMPBELL concludes with the following:

“Only someone familiar with the inside of the system can distinguish between sincere positions based in science and insincere, self-serving position. ... It far too often involves money, power, ego and protection of personal interests above the common good. Very few, if any, illegal acts need to occur” (p. 267–268).

You will only be able to really understand this statement by reading the 18 pages of this chapter. I’m surprised at how objectively “cool” he writes about it as if it were just an ordinary news story. An American drama unfolds. See also the book review on Lügen Lobbies Lebensmittel (Lies lobbies food). This book describes similar situations in Europe.

Scientific Reductionism (p. 269)

We learn how a recommendation must be greatly simplified so as to be understood by a large number of people. CAMPBELL goes over how the 1982 National Academy of Sciences (NAS) report on Diet, Nutrition and Cancer, of which he was a co-author, was the first expert panel report that deliberated on the association of diet with cancer. It included chapters on individual nutrients. Although they recommended getting these nutrients such as vitamins, from natural foods and not pills or supplements, the report found its way to the corporate world and was used as a money-making opportunity. The next thing you know vitamin pills are being advertised as products that prevent cancer. As an example, CAMPBELL describes a product called Healthy Greens, which is “a multivitamin supplement of vitamins A, C and E, beta-carotene, selenium and a miniscule half-gram of dehydrated vegetables” (p. 269).

This led to a year-long legal process initiated by the Federal Trade Commission (FTP) against General Nutrition Corporation (GNC). The FTP used CAMPBELL as an expert on the case. Despite the fact that this was a pretty clear case, GNC managed to get it settled by agreeing to pay what was a ridiculously low fine as compared to the revenues the product generated.

The 1982 National Academy of Sciences (NAS) report was published only as a watered-down version. For example, the original data on the fat content of food was altered “and recommended reducing our fat intake from 40% to 30% of calories, although this goal of 30% was an arbitrary cutoff point.” This is because “the director of the United States Department of Agriculture (USDA) Nutrition Laboratory told us that if we went below 30%, consumers would be required to reduce animal food intake and that would be the death of the report” (p. 271).

He then discusses a study started in 1976, which had enrolled 120,000 nurses “to investigate the relationship between various diseases and oral contraceptives, post-menopausal hormones, cigarettes and other factors, such as hair dyes.5 Beginning in 1980, Professor Willett added a dietary questionnaire to the study and four years later, in 1984, expanded the dietary questionnaire to include more food items. This expanded dietary questionnaire was mailed to nurses again in 1986 and 1990” (p. 272).

The data was collected by the organization for two decades with a budget of 4–5 million dollars annually. This prospective cohort study gained a lot of attention. Frank E. Speizer and Walter C. Willett are regarded as the founders of the Nurses’ Health Study. Willett also wrote the book Eat, Drink, and Be Healthy.

The author criticizes this study harshly and gives some very good reasons for his criticism. “For example, the United States Department of Agriculture (USDA) national school lunch program counts French fried potatoes as a vegetable” (p. 273).

The nurses’ diet turned out to contain even more meat than that of the average American diet. The nurses consumed twice the recommended daily amount of 9 to 10% protein. And of the total protein consumed, 78–86% came from animal-based foods. Their diet included very few whole plant-based foods. He includes a graph developed by Professor Carroll (p. 275) to show the significance of this in terms of cancer.

The group was definitely not homogeneous. Those with a high intake of fat were up to 50–55% fat relative to total calories. Those who reduced the fat content simply consumed less fatty meat, such as chicken and fish, and chose low-fat crackers and low-fat chipscookies, and other types of junk food.

We therefore find only small differences in overall health, but a big difference in terms of the proportion of fat consumption. The study had serious flaws and as a result, false conclusions were drawn. Such studies that attempt to isolate just one substance don’t reveal the whole truth, but The China Study does indeed cover the full spectrum.

CAMPBELL shows a number of false conclusions from studies he had criticized. Just one example: “we found no evidence that lower intake of total fat or specific major types of fat was associated with decreased risk of breast cancer” (p. 279). Of course, a study like this would come to such a conclusion—and it cost more than $100 million to boot.

The author then exposes the conflicts he has encountered by publishing his correspondence with Dr. Hu and Professor Willett. In personal conversation, Willett said to him, “You may be right, Colin, but people don’t want to go there” (p. 287).

The “Science” of Industry (p. 289)

In this chapter, the author shows just how much power the industry has by listing several sales figures that I am not going to repeat here, as I have already taken up this subject in the book review on Salt Sugar Fat.

The author then lists a number of “industry groups that work to increase general demand for their products. ... the most powerful among them have yearly budgets in the hundreds of millions of dollars” (p. 290).

When CAMPBELL was just starting The China Study, he learned about a group of professors who had formed a committee under the direction of Professors E. M. Foster and Michael Pariza. Their committee was financed by the meat and dairy industries and had been given the task of monitoring people and institutions who “might do ‘harm’ to their industry” (p. 290) With a marketing budget of, for example, $165 million in 2003, Dairy Management Inc. was and is able to increase the demand for dairy products. Their target group: young children and their mothers. CAMPBELL then describes some of their marketing campaigns.

The public and press like short headlines like drinking milk reduces cancer risk” (p. 297). These attract attention even if they are just empty talk. To give an example, CAMPBELL describes how Professors Bauman and Pariza used tricky experimental methods to get results showing that the CLA (conjugated linoleic acid) in milk reduces tumors in rats that are given carcinogens. Had they not used these tricky methods, their research results would most likely have been completely different.

Soon after the discovery of the carotenoid lycopene in 1995, the food industry reported that eating more tomatoes and tomato-based dishes including pasta sauces lowers a person’s risk for prostate cancer. This immediately opened up a new market for dietary supplements.

The citrus industry constantly praises the vitamin C content in citrus fruits, and they do so very successfully. Other natural foods that contain even more vitamin C just don’t have a lobby. That’s why you probably think that citrus fruits are the best source of vitamin C (p. 303).

CAMPBELL gives a few examples of other foods containing a high amount of vitamin C. He states that papayas, for example, contain (at 80 mg/100 g) four times more vitamin C than oranges. However, this is not entirely true, as oranges and lemons contain about 50 mg/100 g of vitamin C, definitely significantly less but not four times less.

But for peppers (capsicum, chili peppers, and bell peppers) this does hold true as 0.1 to 0.4 percent of their weight is vitamin C. Other vegetables are also good sources of vitamin C, for example, brussels sprouts contain 112 mg, kale 105–120 mg, fennel 93 mg, cauliflower 69 mg, kohlrabi 65 mg, and spinach 40–150 mg. That is definitely more vitamin C than is contained in oranges. In the fruit category, acerola (also called Barbados cherry) is in the lead with 1,400–4,500 mg! (at least in acerola fruit juice.) Rose hips are more well-known for their high vitamin C content at 1,250 mg, in other words 25 times more vitamin C than in citrus fruits, followed by the common sea-buckthorn with 450 mg and currants with 177 mg.

Back to The China Study: Yes, strawberries and garden strawberries with 64 mg and broccoli (raw 115 mg; cooked 90 mg) contain more vitamin C than oranges, but peas contain less than 50 mg at 41 mg. Now do you know what I mean about the power lobbies have—or were you already aware of this?

Government: Is It for the People? (p.305)

“Expert government panels have said it, the surgeon general has said it and academic scientists have said it. More people die because of the way they eat than by tobacco use, accidents or any other lifestyle or environmental factor” (p. 305).

The author explains how the government acts in practice. He shows the nonsense that occurs by providing various examples from a report issued in 2002 by the Food and Nutrition Board (FNB) (part of the Institute of Medicine, IOM): “To meet the body’s daily energy and nutritional needs while minimizing risk for chronic disease, adults should get 45% to 65% of their calories from carbohydrates, 20% to 35% from fat and 10% to 35% from protein. ...

... added sugars should comprise no more than 25% of total calories consumed. ... added sugars are those incorporated into foods and beverages during production” (p. 306).

Drs. CAMPBELL write the following about this in The China Study, “This report says that we can consume a diet containing up to 35% of calories as fat; this is up from the 30% limit of previous reports. It also recommends that we can consume up to 35% of calories as protein; this number is far higher than the suggestion of any other responsible authority” (p. 306). This is an incredible travesty in the face of the scientific evidence that exists on the subject.

With what you know now from The China Study, the above presents a pretty grim picture of what’s going on. The reason for this are explained below. But bear in mind that “the news release starts off by stating the report’s objective of ‘minimizing risk for chronic disease’ ” (p. 306).

According to these recommendations, a daily menu plan could look like this:

Breakfast: 1 cup Froot Loops, (very sugary breakfast cereal containing harmful food colors), 1 cup skim milk, 1 package M&M’s milk chocolate candies. Lunch: grilled cheddar cheeseburger. Dinner: 3 slices pepperoni pizza, 1 soda (16 oz.), 1 serving Archway sugar cookies. Although this would only add up to 1,800 cal, it would be anything other than healthy.

And for lunch, a grilled cheeseburger with cheddar cheese. Image: Renee Come. See paragraph above.

To avoid any confusion, I would like to add a note here about “pepperoni pizza.” Per Wikipedia: Pepperoni, also known as pepperoni sausage, is an American variety of salami, usually made from cured pork and beef mashed together.” However, The term pepperoni is a corruption of peperoni, the plural of peperone, the Italian word for bell pepper. The first reference using pepperoni to refer to a sausage dates to 1919. In Italian, the word ‘peperoncino’ (diminutive of peperone) only refers to hot and spicy peppers, or sometimes to small, sweet kinds, while ‘peperoni’ refers only to sweet peppers, such as bell peppers.” This term sometimes causes confusion. The author is using it in the American sense of the word.

What would be right? The body needs a minimum of 5 to 6% dietary protein, but responsible scientists recommend 9–10% in order to maintain a safety margin in case of poor composition.

About the same time, an expert panel of the World Health Organization (WHO), and the panel’s spokesperson Professor Phillip James wanted to recommend an upper safe limit of 10% for added sugar.

“According to the Guardian newspaper of London, the U.S. sugar industry was threatening ‘to bring the World Health Organization to its knees’ unless it abandoned these guidelines on added sugar” (p. 310). In spite of these efforts, the U.S. and WHO recommendations for added sugar are now quite different.

CAMPBELL then gives several other examples of ways that individuals and committees are connected to the food industry and how this affects the public. He writes that the Food and Nutrition Board Report discussed above sets us back by years.

The author also describes a positive example in which Dr. Antonia Demas’ Food is Elementary educational program was incorporated into 300 school lunch and behavioral rehabilitation programs around the United States. Her program, which is entirely plant-based, is the total opposite of the government requirement that schools have to offer cow’s milk—and rely mostly on an inventory of animal-based products.

Big Medicine: Whose Health Are They Protecting? (p. 321)

The author asks the question: “So why doesn’t the medical system take nutrition seriously? Four words: money, ego, power and control.” The author isn’t referring to individual doctors, but instead to the system with which they work, the system that should be responsible for promoting good health.

He tells us the story of the successful surgeon Dr. Esselstyn. After Esselstyn read the book, The McDougall Plan by Dr. John A. McDougall, he realized that patients who ate a lot of meat, fat, and refined foods needed to be treated with a low-fat, plant-based diet.

With the official guidelines to back him up, one of Esselstyn’s colleagues said the following to a patient who wanted to take part in Esselstyn’s dietary program: “Now you listen to me. There is no way to reverse this disease” (p. 325). 

Esselstyn believes that the problem lies in the lack of nutrition training doctors have in medical school and in the form of continuing education. Big companies wouldn’t develop an interest in a natural diet. “This situation is dangerous. Nutrition training of doctors is not merely inadequate; it is practically nonexistent. ...”

“It gets even worse! When nutrition education is provided in relation to public health problems, guess who is supplying the ‘educational’ material? The Dannon Institute, Egg Nutrition Board, National Cattlemen’s Beef Association, National Dairy Council, Nestlé Clinical Nutrition, Wyeth-Ayerst Laboratories, Bristol-Myers Squibb Company, Baxter Healthcare Corporation and others have all joined forces to produce a Nutrition in Medicine program and the Medical Nutrition Curriculum Initiative” (p. 327).

The Dannon Institute was founded and is “fed” by dairy giant Danone. Danone has 81 thousand employees and generates annual sales of more than 15 billion euros. It is interesting to see how well the egg industry uses Wikipedia. Go here to see for yourself. The same goes for the National Cattlemen’s Beef Association (NCBA) (the meat industry) and Dairy Management Inc. (the dairy industry). Wyeth is a pharmaceutical corporation with $22 billion in annual sales, which is now owned by Pfizer, a company with around $60 billion in annual sales—and $15 billion in profit. In 2009, Bristol-Myers Squibb, in the same industry, had sales of $18.8 billion and achieved a net profit of $10.6 billion. Baxter International makes its money off of people’s kidney problems.

It is therefore understandable that physicians recommend that osteoporosis patients drink more milk. “The health damage that results from doctors’ ignorance of nutrition is astounding” (p. 329).

CAMPBELL describes some exceptions, for example, the experiences of Dr. John A. McDougall, who suffered a severe stroke at age 18 and as a result, developed a special appreciation of life. It is particularly interesting to read about his experiences as a junior doctor and the conflict he had with the establishment. His new understanding of nutrition and desire to share this with his patients nearly cost him his job and career. (p. 330, EE: From then on, his diet was mostly vegan, Wikipedia)

In the next section “Hooked on Drugs,” the author describes the ties between the medical profession and the drug industry. For example, big companies pay PR agencies to write scientific articles and then find researchers who agree to be listed as the authors of these ghostwritten articles (p. 333).

“Twenty percent of all new drugs have serious unknown side effects, and more than 100,000 Americans die every year from ‘correctly’ taking their ‘properly prescribed’ medication” (p. 335).

On the following pages, the author describes the fates of the successful, if not exactly conventional medical doctors Dr. McDougall (see his website www.drmcdougall.com) and Dr. Esselstyn. “Both Esselstyn and McDougall have now been denied reentry into the establishment, after headline-making success at healing people with a nutritional approach” (p. 341). But just before that, he describes the following: “An interesting situation is now developing: just as with Dr. McDougall, many of the Clinic ‘bigwigs’ with heart disease have themselves gone to Esselstyn for treatment and lifestyle counseling. They know it works, and they seek out the program on their own” (p. 341).

Repeating Histories (p. 343)

In 1985 during a sabbatical in England, CAMPBELL had the opportunity to read much on the topic of diet and cancer at the Bodleian Library in Oxford, and at the Royal College of Surgeons (RCS) and the Imperial Cancer Research Fund (now called Cancer Research UK) in London.

He found several books written by George Macilwain (1797–1882), who was a prominent surgeon in the early 19th century. “He became vegetarian at the age of forty, after identifying ‘grease, fat and alcohol’ as being the chief causes of cancer.” (EE: Please note how old he lived to be, which was remarkable for his time.)

He described the concept of the constitutional nature of disease and that a disease is not the result of the failure of a single organ or cell. “It is the result of multiple systems throughout the body breaking down” (p. 343).

Plato and Socrates knew that 2,500 years ago. Macilwain describes a conversation between them and Glaucon. Glaucon’s arguments seem particularly interesting. Frederick L. Hoffman, who was instrumental in founding the American Cancer Society, also “knew that diet was the way to prevent and treat disease” (p. 345).

The authors again list out a number of facts and demonstrate how “unhealthy” most Americans are. To this end, they present 15 impressive statistics on the state of the population. Europe is currently heading in the same direction. ...

Mein Lebenslauf hat mich motiviert, die "Stiftung G+E, Gesundheit und Ernährung" zu gründen. Im Beitrag "Schicksalsschläge, tödliche Krankheit, Gesundheit, Leben!" schildere ich etwas davon. Ein ebenso wichtiger Punkt bildet die Erfahrung aus dem Aufbau von Radiomuseum.org: Es bekommen zu viele Männer bereits ab Alter 65 schwerwiegende Krankheiten. Das gilt sicher auch für Frauen - und ganz allgemein altern wir zu rasch. So lange wie möglich zu leben ist nicht das Ziel, sondern so aktiv, positiv und glücklich wie möglich. Der Weg des geringsten Widerstands führt nicht dazu. Ganz im Gegenteil: nur im Leid schafft man grössere persönliche Veränderungen. Im Alter von 41 Jahren brachte mich die Todesangst vor meinem Krebsleiden dazu, über mein Leben zu reflektieren und auch bezüglich Krankheit selbstverantwortlich zu handeln. Heute bin ich froh, dass ich durch sehr schwierige Lebensphasen gehen musste. Dadurch konnte ich meine Lebensführung so verändern, dass ich auch im achtzigsten Lebensjahr (2015) >60 Stunden pro Woche am PC arbeiten und dabei leistungsfähig bleiben kann. Es ist falsch, so viele Stunden sitzend zu verbringen (früher waren es mehr), doch versuche ich das durch Ausdauersportarten (schnelles Wandern, Bergwandern, seit 2014 auch durch Joggen) und leider nicht immer jeden Tag ausgeführte Übungen (7 Min Workout ab iPhone) auszugleichen. Ich darf aber annehmen, dass die langjährige (Pesci-)vegane Ernährung mit ca. 90% Rohkostanteil den Ausschlag für meine Gesundheit gibt. Leider sind es mit Sicherheit nicht meine Gene. Auch als Angestellter sah ich meine Arbeit nie als Job, sondern als Hobby, das mich interessierte. Als ich eigene (kleine) Firmen aufbaute, war mir das Wohlergehen der Mitarbeiter besonders wichtig. Erfolg oder Misserfolg hing zu einem grossen Teil von ihnen ab. Es war nie mein Ziel, reich zu werden, sondern etwas individuell und intelligent aufzubauen, so dass es vielleicht Erfolg haben kann. Trotzdem kann ich es mir nun erlauben, mit meiner Erfahrung und meinen Möglichkeiten etwas aufzubauen, das interessierten Menschen zugut kommen kann. Zum Glück geben mir auch junge Menschen, die an "diet-health.info" mitarbeiten, das Gefühl echter Teamarbeit. Einige arbeiten mit mir persönlich zusammen, wie ein Software-Entwickler neben einem Studium. Doch mit Skype und TeamViewer ist es möglich, mit geographisch weit verstreuten MitarbeiterInnen zu arbeiten, wie z.B. mit professionellen ÜbersetzerInnen. Selbst Professoren oder Ärzte beteiligen sich an diesem etwas speziellen Projekt, indem sie eigene Texte beisteuern. Unsere Themenbereiche erfassen eigentlich alles, was uns Menschen ausmacht: Gesundheit - Prinzipien/Allg. - Heilkunde - Ernährung - Produktion/Handel - Drogen - Aktivität - Lifestyle - Politik - Wellness - Natur - Umwelt - Persönlichkeit - Ethik - Soziales / Religion. Noch weiss ich nicht, ob "diet-health.info" mit diesem Versuch, den Menschen "nur" solide Zusammenhänge zu vermitteln, auch die notwendige Beachtung erhalten kann. Doch meine ich, dass es reflektierende Menschen gibt, die Zusammenhänge verstehen wollen, statt jedem Modetrend lemmingehaft nachzugehen oder sich zu einem leicht begehbaren Weg (ver-)führen zu lassen. Ob die auch die notwendige Aufmerksamkeitsspanne und den Willen zum Lesen mitbringen? Jedenfalls fehlte mir eine solch umfassende Quelle, die mir ungefärbte Antworten auf wichtigste Fragen geben kann. Deshalb versuche ich diesen "vorher vergeblich gesuchten Hafen" aufzubauen. Hoffentlich habe ich auch die Zeit und Kraft dazu.
