Kidney beans

Ripe kidney beans contain toxic lectins and should only be eaten in small quantities. The name of the bean comes from its shape that resembles a kidney.
Macronutrient carbohydrates 71.09%
Macronutrient proteins 27.93%
Macronutrient fats 0.98%

The three ratios show the percentage by weight of macronutrients (carbohydrates / proteins / fats) of the dry matter (excl. water).

Ω-6 (LA, 0.2g)
Omega-6 fatty acid such as linoleic acid (LA)
 : Ω-3 (ALA, 0.3g)
Omega-3 fatty acid such as alpha-linolenic acid (ALA)
 = 1:2

Omega-6 ratio to omega-3 fatty acids should not exceed a total of 5:1. Link to explanation.

Here, essential linolenic acid (LA) 0.18 g to essential alpha-linolenic acid (ALA) 0.28 g = 0.64:1.
Ratio Total omega-6 = 0.18 g to omega-3 fatty acids Total = 0.28 g = 0.64:1.
On average, we need about 2 g of LA and ALA per day from which a healthy body also produces EPA and DHA, etc.

Nutrient tables

Raw kidney beans should only be eaten in very small amounts as they contain toxic substances. However, these are inactivated when the beans are heated. Read more in the section below titled “Toxicity of raw kidney beans.” Kidney beans are sold dried (bulk and packaged) and canned (in cans or jars).

General information.

From Wikipedia: “The kidney bean is a variety of the common bean (Phaseolus vulgaris) bean. It is named for its visual resemblance in shape and color to a kidney. Red kidney beans should not be confused with other red beans, such as adzuki beans.”


“There are different classifications of kidney beans, such as:

  • Red kidney bean (also known as: common kidney bean, Rajma in India, Surkh (Red) Lobia in Pakistan).
  • Light speckled kidney bean (and long shape light speckled kidney bean).
  • Red speckled kidney bean (and long shape light speckled kidney bean).
  • White kidney bean (also known as cannellini or Lobia in India or Safaid (White) Lobia in Pakistan).”

Culinary uses:

“Red kidney beans are commonly used in chilli con carne and are an integral part of the cuisine in northern regions of India, where the beans are known as rajma and are used in a dish of the same name. Red kidney beans are used in New Orleans and much of southern Louisiana for the classic Monday Creole dish of red beans and rice. The smaller, darker red beans are also used, particularly in Louisiana families with a recent Caribbean heritage. Small kidney beans used in La Rioja, Spain, are called caparrones. In the Netherlands and Indonesia, kidney beans are usually served as soup called brenebon.”

Toxicity of raw kidney beans:

“Raw kidney beans contain relatively high amounts of phytohemagglutinin, and thus are more toxic than most other bean varieties if not pre-soaked and subsequently heated to the boiling point for at least 10 minutes. The US Food and Drug Adminisitration recommends boiling for 30 minutes to ensure they reach a sufficient temperature long enough to completely destroy the toxin. Cooking at the lower temperature of 80 °C (176 °F), such as in a slow cooker, can increase this danger and raise the toxin concentration up to fivefold. Canned red kidney beans, though, are safe to use immediately.”
