Green Peas: Nutrients, What Research Shows and Safety

Green peas are the fresh, round seeds of the pea plant (Pisum sativum L.), a member of the legume family (Fabaceae). The seeds are eaten from the pod, fresh, frozen or canned, and people eat them for protein, fiber and vitamins. This page keeps the whole food apart from supplements, protein powders and hype, and says plainly what research does and does not show.

Read this first

• Allergy: pea is a known legume allergen. In one children's clinic study, pea was the most common legume allergy and caused half of the severe reactions to the legumes studied. [7] For trouble breathing or swelling of the face or throat, call 911.
• Digestion: peas, like other pulses, can cause gas and bloating in people with a sensitive gut or irritable bowel syndrome (IBS). [10] A clinician or dietitian can help with this.
• Medicines and kidneys: peas have some vitamin K (important if you take warfarin) and some potassium (important with kidney disease or certain blood pressure medicines). Ask your clinic. [2][4]
• Evidence in one line: peas are a good everyday source of fiber, vitamin C, vitamin K and folate. We found no trial showing that eating green peas treats or prevents a disease; most health findings are about legumes in general.

What is in it (USDA values)

Raw green peas, USDA FoodData Central item 170419 (SR Legacy). [1] USDA household portion: 1 cup = 145 g.

% Daily Value uses the FDA 2016 Daily Values; values vary with variety, ripeness and storage. [1]

Plant compounds. USDA lists lutein plus zeaxanthin (2,477 µg per 100 g) and beta-carotene (449 µg per 100 g) in raw green peas. [1] These are plant pigments (carotenoids). We did not read a human trial of green peas for eye or other outcomes, so no benefit is claimed. Peas also contain sugars called raffinose-family oligosaccharides, studied in the lab as a cause of digestive gas; this is chemistry, not a health benefit. [11]

What research says

Eaten as food vs taken as a supplement or extract. The findings above are about eating peas or legumes as part of a diet. Pea protein powders and extracts are different products, studied separately; we did not read a trial of them and make no claim. A food being rich in a nutrient is not proof that eating it treats a disease, and observational links cannot show cause.

How much is a normal serving

This is information, not a prescription. The WHO healthy diet fact sheet (January 2026) says at least 400 g of fruits and vegetables a day for people older than 10. [15] The NHS counts 80 g of fresh, canned or frozen vegetables as one portion (last reviewed 9 June 2026). [16] The USDA household portion for raw green peas is 1 cup (145 g). [1]

Fresh vs frozen. A laboratory study of eight fruits and vegetables, peas included, found frozen produce was generally comparable to fresh, with exceptions: peas were lower in riboflavin and in beta-carotene after freezing. [6] Vitamin C did not differ for most items in that study. [6] Cooking effects on peas: proper evidence not found in the sources we read. See fresh, frozen and canned produce.

Safety, allergy and medicines

• Pea allergy. In a 2026 study of 55 children with legume allergy, pea (71%) and lentil (69%) were the most common, many children were allergic to several legumes, and pea caused half of the severe reactions to the legumes studied. [7] A 2025 study of 203 children with non-priority legume allergy (lentil, chickpea, pea, bean) found that about a quarter outgrew a pea allergy by age 15 (23.5%). [8] Peanut is also a legume; the studies do not mean everyone allergic to one legume reacts to all. Ask an allergist. See food allergy basics and emergency signs.
• FODMAPs and gas. A trial in 21 people with a sensitive gut or IBS and 21 controls found pulse meals caused more symptoms in the sensitive group. [10] A review says the low-FODMAP diet (cutting fermentable carbohydrates) has evidence in IBS, but is hard to do safely without help. [12] We did not read an official FODMAP rating for green peas specifically: proper evidence not found. A dietitian can test it with you.
• Warfarin and vitamin K. MedlinePlus says people taking warfarin may need to watch vitamin K foods, that sudden changes can change the medicine's effect, and to ask a provider. [2] Raw green peas have 24.8 µg per 100 g, less than leafy greens. [1] Do not change a prescribed medicine yourself. See foods and medicine interactions.
• Potassium, kidney disease and medicines. MedlinePlus says people with kidney problems, particularly on dialysis, should not eat too many potassium-rich foods, and that ACE inhibitors are a common cause of high blood potassium. [4] Peas have 244 mg per 100 g. [1] See foods, kidney disease, potassium and oxalates.
• Pregnancy. MedlinePlus says people planning pregnancy are advised to take folic acid because it can be hard to get enough from food. [3] See foods in pregnancy.
• Gout. The NHS gout page does not name vegetables to avoid and says a doctor may give a food list. [13] Proper evidence not found for or against green peas, so we make no claim.
• Pesticide residues, oxalate, goitrogens, histamine: proper evidence not found in the sources we read; no claim is made.

Choosing, storing and food safety

• Keep perishable produce, and all pre-cut or packaged produce, in a refrigerator at 40°F (4°C) or below. [14]
• Rinse fresh pods or peas under running water; do not use soap, detergent or produce wash. Washing reduces bacteria but does not remove all of them. [14]
• Choose packaged produce only if it is refrigerated or on ice, and keep produce away from raw meat. [14] Cooking produce thoroughly kills harmful bacteria. [14]
• The FDA page does not address frozen peas, so we make no claim about them.
