A healthy and cheap source of protein!

Like all dried legumes, red kidney beans are among the plant-based foods that are richest in protein, yet unlike animal proteins, they are still fat-free.

These two characteristics provide major health benefits, contributing to a balanced, low-cost diet!

A natural plant-based diuretic

Red kidneys are rich in potassium and low in sodium, naturally giving them diuretic properties.

They also contain:

  • calcium
  • magnesium

Red kidney beans are also:

  • a source of vitamin B9 (for cellular renewal, particularly important for pregnant women for fetal development, for growing children, and for convalescents).
  • a source of potassium (for the nervous system, muscular function, and blood pressure)
  • a source of iron (for cognitive function, red blood cells, the immune system, energy, and fatigue reduction)
  • a source of phosphorus (for energy, bone and teeth health, and cellular membranes)
  • a source of fiber (bowel movement regulation, satiety)

Vegetable patch or
urban balcony?

Red kidney beans are annuals that can be bushy or climbing. Each pod holds four to twelve seeds. Red kidneys grow well in light, rich, deep, aerated, well-drained soil, in a hot and temperate climate.

Choosing and storing
your red kidney beans

Choose your red kidneys well:

  • Choose the “freshest” ones; they should take less time to soak before being cooked and are easier to digest, making them less likely to cause flatulence.

Properly store your red kidneys:

  • Store them in a cool, dark place, in a sealed container, for one year maximum. Otherwise they will be more difficult to digest.

Tips and

How to prepare red kidney beans

Like most dried legumes, they need to be soaked in cold water overnight before being cooked. Cooking times vary depending on their size and range from 30 to 90 minutes in boiling water.

If they are canned, you can add them directly to your dishes. They can be eaten cold or lightly reheated.

Red kidney beans go well with…

They are well-known as one of them main ingredients of chili con carne, literally “chili with meat.” Contrary to popular belief, this internationally renowned dish is not native to Mexico but instead hails from the southern United States in the pure Tex-Mex tradition, with red kidneys, tomatoes, meat, onions, and spice.

Vegetarians can leave out the meat and eat the chili with bread for plant-based protein balanced between dried legumes and grains.

Chatrou fricassee is a national dish from the French West Indies made of red kidneys slow cooked with tomatoes and spices, to which octopus pieces (chatrou) are added.

Finally, red kidneys can also be a good base for salads, for example with shallots, garlic, tomatoes, olives, and a spicy vinaigrette (the same ingredients as in chili, but cold!).

Can everyone
eat them?


Young children

Red kidney beans can irritate the bowel, be difficult to chew, and present a risk of pulmonary aspiration. Therefore they should not be given to children before the age of 15 months.

And everyone else

To fully benefit from pulse proteins, eat a grain product or nuts and seeds along with red kidneys.

They are rich in lysine (an amino acid) but have very little methionine (another essential amino acid). As for grain products (wheat, rice, etc.), nuts, and seeds, they contain essential amino acids that pulses lack or contain only in small quantities. So the two together are a winning combination!

Where do they come from?
Origins and varieties

Origins: For thousands of years, dried beans, along with corn, have been the dietary cornerstones of the Americas, where people continue to eat them today. Red kidneys are one of the most consumed foods in the world.

The main dried bean producers are Myanmar, India, Brazil, China, the United States, Tanzania, and Mexico. Around 85% of dried beans are eaten in their country of production. Latin America has the highest rate of consumption per capita, mainly of colorful pinto beans, black beans, and red beans.
