Lentils, chickpeas and peas

Lentils, chickpeas, split peas, pigeon peas, black-eyed peas, fava and lupini beans: dried seeds of the legume family, rich in fiber and protein.

Beans

Black, kidney, pinto, navy, white, lima, mung and adzuki beans. Raw kidney beans are toxic, so how you cook them matters.

Soy foods

Soybeans, edamame and tofu: soy has its own allergy and isoflavone questions.

Legume flours and prepared foods

Hummus, canned and baked beans, falafel, bean pasta, legume flours, soy and pea protein, and sprouts: legumes in ready-to-eat forms. Raw sprouts carry a food-poisoning risk.

Regional and lesser-known legumes

Moth beans, horse gram, urad dal, hyacinth and winged beans, bambara groundnut and jack beans: staple foods in parts of Asia and Africa. Some must be cooked carefully to be safe.

Legume pods and tree legumes

Carob and mesquite are legume-family trees whose pods are eaten. Tamarind is listed from Spices. They are not beans, and each has its own uses and cautions.

Related minerals, nutrients and supplements

Legumes work alongside other nutrients. Here is what our sources link to them.

  • Beta-carotene

    Vitamin A: The body can convert beta-carotene to vitamin A.

  • Vitamin E

    Vitamin A: Vitamin E and beta-carotene were tested together in the Finnish smoker trial.

  • Calcium

    Vitamin D: Vitamin D increases calcium absorption; both matter for bones, and treatment of rickets and osteomalacia includes both.

  • Phosphorus

    Vitamin D: NHS says vitamin D helps regulate calcium and phosphate.

  • Vitamin K

    Vitamin E: MedlinePlus says vitamin E helps the body use vitamin K; both affect blood clotting, which matters for people on blood thinners.

  • Selenium

    Vitamin E: Vitamin E and selenium were tested together and apart in the SELECT prostate cancer trial.

  • Vitamin C

    Vitamin E: Vitamin C and vitamin E were pooled with other antioxidants in the Cochrane mortality review.

  • Vitamin D

    Vitamin K: Vitamin D with K2 products exist; the site page does not claim an added benefit.

  • Folate

    Vitamin B1 (thiamin): The NHS page covers B vitamins together; MedlinePlus says doctors may recommend other vitamins alongside thiamin for beriberi.

  • Other B vitamins

    Vitamin B2: MedlinePlus says riboflavin works with the other B vitamins.

  • Tryptophan

    Vitamin B3 (niacin): Pellagra comes from too little niacin or tryptophan in the diet, so both matter for avoiding deficiency.

  • Biotin

    Vitamin B5: MedlinePlus covers pantothenic acid and biotin together; both are needed for growth and metabolism and for making fatty acids.
