Pigeon Peas: Nutrients, What Research Shows and Safety

Pigeon peas are the seeds of Cajanus cajan, a legume (pulse) grown in warm regions. They are eaten cooked, fresh-green or dried, in stews, rice dishes and dals. People eat them for fiber, plant protein, folate and potassium, and in some places the plant is also used in traditional remedies. This page keeps those uses apart: it covers the cooked seed as a food, says plainly that human evidence for health claims is thin, and does not cover leaf or seed extracts.

Read this first

• Evidence is very limited. We found no trial of eating pigeon peas as a food for cholesterol, blood sugar or any disease in the sources we read. What the pooled pulse studies show (small LDL and blood sugar effects) is for pulses as a group. [6] [7]
• Traditional use is not proof. A 2026 survey of 400 people in Nigeria found pigeon pea and neem extracts are used for malaria and typhoid because of access, cost and family tradition. The survey does not test whether they work. [4]
• Gas and bloating are common with pulses; people on a low-FODMAP plan are usually asked to limit them for a short time with a dietitian. [11]
• Kidney disease: pigeon peas are a source of potassium (about 14% of the Daily Value per cooked cup). Ask your kidney dietitian before changing how much you eat. [1] [12]
• Allergy: we read no source on pigeon pea allergy. Allergy to other legumes is reported, and for trouble breathing or swelling of the face, lips or throat you should call 911 (or your local emergency number). [9]

What is in it (USDA values)

The table is for cooked pigeon peas: mature seeds, boiled, without salt (USDA FoodData Central item 172437, SR Legacy). [1] The serving column is the USDA household portion of 1 cup, 168 g. [1] Raw dry pigeon peas (item 172436) are 343 kcal, 21.7 g of protein and 1392 mg of potassium per 100 g because they hold little water, so do not compare raw and cooked rows. [2]

% Daily Value uses the FDA 2016 Daily Values; the serving figures are the per-100-g values multiplied by 1.68, and values vary with variety, growing place and cooking.

Plant compounds: a 2026 laboratory study found that wild-fermented pigeon peas had higher antioxidant readings in test-tube assays. The authors say bioavailability and compound identity still need study, and the work used extracts, not people. [5] We read no study showing these readings matter for health.

What research says

Eaten as food vs extracts. Everything above that touches health claims for pigeon pea used extracts or surveys, not cooked peas eaten as a meal. Nothing here supports using pigeon pea leaf or seed extracts as a treatment.

How much is a normal serving

The USDA household portion for cooked pigeon peas is 1 cup (168 g), about 203 kcal, with 11.3 g of fiber, 11.4 g of protein and 645 mg of potassium. [1] NHS counts 80 g of pulses as one portion of your 5 A DAY, and pulses count only once a day however much you eat. [15] In the US, guideline targets of at least 1.5 cups a week of cooked pulses were met by 19.9% of people in 2017-2018, and we found no pigeon-pea-specific intake figure. [17] This is information, not a prescription for you.

Safety, allergy and medicines

• Allergy: the 2024 review of legume allergens covers pea, chickpea, lentil and lupine, not pigeon pea; it says peanut allergy can bring cross-reactions with other legumes. Proper evidence about pigeon pea allergy was not found in the sources we read. [9] See peanuts and food allergy basics and emergency signs. Call 911 for trouble breathing or swelling of the face or throat.
• Lectins: Health Canada's page on lectins in dry legumes names soybeans, lentils, lima beans and kidney beans; it does not name pigeon peas. We read no source on pigeon pea lectin poisoning, so eat them fully cooked. [10] See lectins in beans.
• Gas, bloating and FODMAPs: a hospital leaflet says galacto-oligosaccharides are mainly found in beans and pulses and asks patients to avoid them for 4 to 6 weeks as a temporary diet with a dietitian. It does not list pigeon peas, so we give no portion. [11] See beans, gas, FODMAP and digestion.
• Kidney disease and potassium: cooked pigeon peas have 384 mg potassium and 119 mg phosphorus per 100 g. [1] The National Kidney Foundation says animal sources of phosphorus are absorbed better than plant sources and that additive phosphate is absorbed at more than 90%. [12] A 2021 review found human data suggest at least 50% of phytate phosphorus is absorbed. [13] Ask a kidney dietitian. See foods, kidney disease, potassium and oxalates.
• Extracts and sickle cell disease: the Cochrane review does not support using a Cajanus cajan extract for sickle cell disease and calls for better trials. [3] Do not replace prescribed treatment with plant extracts.
• Pregnancy and breastfeeding: MedlinePlus says anyone pregnant should be sure to get enough folate. USDA lists 111 mcg folate per 100 g of cooked pigeon peas; MedlinePlus names lentils and dried beans, not pigeon peas. [14] [1] NHS says to take a folic acid supplement in pregnancy as well; its page does not name pigeon peas. [16] We read no pregnancy advice about herbal pigeon pea extracts.
• Young children: CDC advises preparing food in a shape and texture that suits the child and says mashing helps prevent choking; it lists whole beans among foods to avoid and does not name pigeon peas. [18]
• Medicines: we did not find a source we could read that ties pigeon peas as a food to a specific medicine interaction.

Choosing, storing and food safety

• We did not read a source with storage times for dry or cooked pigeon peas. A 2026 review says fungal infection generally lowers the nutritional value of pulse seeds and that the main fungi were studied in corn, peanut and cotton, so look for mold or damp in dry pigeon peas and discard moldy ones. [19]
• Canned pigeon peas exist but we have no USDA data in our file; read the label for sodium. See dried vs canned beans, soaking and sodium.
