Chickpea Flour (Besan): Nutrients, What Research Shows and Safety

Chickpea flour, called besan in India and garbanzo flour in the US, is dried chickpeas (Cicer arietinum, a legume) ground to a fine, pale yellow powder. It is used for flatbreads, batters, pancakes, fritters and gluten-free baking. People choose it for plant protein and fiber and for its possible help with blood sugar and weight. [6] This page is about the flour as food. It keeps the flour apart from whole cooked chickpeas, hummus and pasta made from chickpeas, which are covered elsewhere on the site.

Read this first

• Cook it. The CDC says most flour is not treated to kill germs such as E. coli and Salmonella, and baking or cooking is what does it. [9] Do not eat raw batter or dough, and do not "taste" raw flour.
• Evidence in one line: trials of chickpea foods found a lower blood sugar rise after meals and more fullness in small studies, but the certainty is low, and some results come from bread, pasta or whole chickpeas, not plain flour. [2] [3] [4]
• Allergy: chickpea allergy is reported, mostly in case reports and in children who are also allergic to peas or lentils. For trouble breathing or swelling of the face or throat after any food, call 911 (or your local emergency number). [7] [8] [16]
• Know what is in the bag. Grass pea (Lathyrus sativus) flour is a different flour that carries a nerve toxin and has been linked to a paralysis disease. [14] [15] See "Safety" below.
• Gluten-free? Chickpeas are not wheat, rye or barley, but a flour is only certain to be gluten-free if the label says so, and the FDA limit for that claim is under 20 parts per million. [13]

What is in it (USDA values)

The values are for chickpea flour (besan) (USDA FoodData Central item 174288, SR Legacy) [1]. The serving is the USDA household portion of 1 cup (92 g), which is a lot of flour for one meal; most recipes spread it across several servings. The form is the dry flour, not cooked.

% Daily Value uses the FDA 2016 Daily Values (per cup this is the 100 g percentage scaled by 0.92). USDA lists no Daily Value for energy or sugars. Values vary with variety, growing place and how the flour was milled. Canned or cooked chickpeas have very different numbers because of the water.

Plant compounds: USDA lists 39 mg of phytosterols in 100 g of the flour. [1] Harvard's Nutrition Source says legumes contain resistant starch and oligosaccharides that ferment in the colon, and also soluble fiber. [17] We did not read a measurement of other compounds in chickpea flour specifically.

What research says

Eaten as flour in food vs. whole chickpeas or extracts. Most trials used whole chickpeas, a cooked product or a flour blended into bread. Particle size mattered in the bread trial: only the larger-particle flour lowered the glucose response, which shows that fine milling may change the result. [3] The 15-person trial was funded by a Greek research foundation. [3]

How much is a normal serving

We did not find an official serving size for chickpea flour. The USDA household portion is 1 cup (92 g, about 356 kcal). [1] The bread trial replaced 30% of the wheat flour in the loaf; that describes the study, not advice. [3] Whole chickpeas have a different serving guide; see chickpeas. This page gives information, not a prescription.

Safety, allergy and medicines

• Raw flour. The CDC investigated outbreaks linked to flour or cake mix in 2016, 2019, 2021 and 2023. Grinding does not remove germs and children should not play with or eat raw-flour dough. [9] A UK survey of 882 flour products found Salmonella in 0.1% and Shiga toxin-producing E. coli in 0.8%. [10] We did not find data on chickpea flour specifically. A 2026 study found home oven heating of wheat-based and gluten-free flours did not reach a 5-log reduction in Salmonella, and the authors said it is unknown whether it is good enough for consumers; it tested no legume flour. [11]
• Chickpea allergy. A 2024 review calls chickpea allergy low in incidence but describes exercise-related anaphylaxis after chickpea in two teenagers (case reports), and lists chickpea among legumes with cross-reactions to peanut, lupine, soy and lentil. [7] In a 2026 Italian study of 55 children with legume allergy, the allergies to pea, lentil and chickpea often occurred together (56% to 86%), and 25.5% also had peanut allergy. [8] Neither source discussed chickpea flour specifically. A pediatric review adds that lentils, peas and chickpeas are mainly implicated in the Mediterranean area and India. [18] Chickpea is not on MedlinePlus's list of major food allergens, which includes peanuts and soy, and MedlinePlus says anaphylaxis is a 911 emergency. [16] See food allergy basics and emergency signs.
• Grass pea mix-ups. Grass pea (Lathyrus sativus) contains a toxin called beta-ODAP and is linked to neurolathyrism, a disease that causes stiff, weak legs. [14] In a 2026 survey in Ethiopia, 11.9% of 470 people reported neurolathyrism. [15] A 2024 study of grass pea flours found some varieties above and some below a "safe level" cited by the authors (0.15%). [14] We did not read a source on how often grass pea is mixed into besan. Buy from a trusted maker.
• Acrylamide. FDA says acrylamide can form in plant foods, such as grain products and potatoes, when they are fried, roasted or baked with dry high heat, and not when boiled or steamed. Its advice is to cook to a golden color rather than dark brown, and it does not tell people to avoid such foods. [12] We did not find measurements for chickpea flour fritters or flatbreads.
• Gas and digestion. Legumes contain oligosaccharides and resistant starch that ferment in the colon and can cause gas and bloating in some people. [17] We found no measurement for chickpea flour specifically. See beans, gas, FODMAP and digestion.
• Kidney disease, medicines, pregnancy, children: USDA lists 846 mg of potassium and 318 mg of phosphorus in 100 g of the flour. [1] We did not read a source with limits for chickpea flour, or on medicines or pregnancy. See foods, kidney disease, potassium and oxalates, food and medicine interactions and foods in pregnancy, and ask a clinician.

Choosing, storing and food safety

• Cook all batters and doughs fully. Only baking or cooking kills germs in flour. [9]
• Gluten. Under FDA rules a "gluten-free" label means under 20 ppm of gluten, and a naturally gluten-free food may or may not carry the claim. [13] If you have celiac disease, choose flour labeled gluten-free; see gluten, celiac disease and gluten sensitivity basics.
• Check labels for blends: some "pulse flour" mixes contain other flours.
• Store flour dry and sealed. Because flour keeps for a long time, the CDC advises checking your pantry against recall lists and throwing away recalled flour. [9]
