Chickpea flour: the blood sugar effect depends on what else is in the dough

By a 2025 meta-analysis of 28 single-meal crossover studies, mostly in healthy adults, chickpea meals lowered the rise in blood glucose after eating, a mean difference of -47.89 in the area under the glucose curve (95% CI -64.20 to -31.58). The studies disagreed widely, the certainty was rated low, and three of the authors work for PepsiCo. Chickpea powder or flour was the most tested form, in 19 subgroups against 16 for boiled or canned chickpeas, yet the data were too thin to give flour its own estimate. The single trials show why. In a randomized crossover trial in 38 adults, flatbread with 15 g chickpea flour in a 100 g flour mix did not differ significantly from plain flatbread on post-meal glucose, and each bread was tested in only 9 to 14 people, fewer than planned. Adding guar gum to the same mix cut glucose by 30% or more. In 11 healthy adults, white bread made with chickpea flour gave only a trend toward lower glucose (P=0.087) and a higher insulin response than plain white bread. The big drops belong to a different product. In 20 healthy adults, bread with 30% of a specially processed chickpea powder, whose plant cells stay intact, gave a more than 40% lower glucose response after one meal than plain white bread. That powder was made for research and is not the besan on a shop shelf.

The numbers, per 3.5 oz (100 g)

How much is actually in it

• USDA lists 22.4 g protein, 437 mcg folate and 0.91 mg copper per 3.5 oz (100 g) of chickpea flour (besan), from a single reference record with no sample spread. — USDA SR Legacy record Chickpea flour (besan), FDC 174288, Legumes and Legume Products Evidence E source

What a real portion looks like

• UK national diet survey data link chickpea eating, with chickpea flour among the most consumed chickpea foods, to a doubling of consumers from 6.1% to 12.3% between 2008-2012 and 2016-2019. — 15,655 UK individuals aged 1.5 years and over, NDNS 2008/09-2018/19, four-day food diary (n = 15655) Evidence C source

What your body absorbs

• In a crossover trial in 30 Malawian infants, fractional iron absorption from an iron-fortified infant cereal of whole wheat and chickpea flour was 12.8%, similar to refined wheat (12.1%) and higher than whole oat cereals (7.4 to 9.2%). — Malawian children aged 6-14 months, 70% anemic; 25 g cereal servings with 2.25 mg labeled iron and 13.5 mg ascorbic acid (n = 30) Evidence B source

Safety, limits and interactions

• The FDA tells consumers that flour is a raw food and should never be eaten or tasted raw, in dough or in batter, in advice written about grain flours that does not name chickpea flour. — consumers handling flour at home (US) Evidence E source
  Agency advice: cook flour before eating; home heat treatment is not considered safe

What people believe that the data does not support

• In a crossover trial in 38 adults, 15 g chickpea flour in a 100 g flatbread flour mix lowered post-meal glucose by 30% or more only when combined with guar gum, and chickpea flour alone did not differ from control. — 38 normal-weight adults, flatbreads from 100 g flour mix (n = 38) Evidence B source
  15 g CPF plus 2 or 4 g guar gum: PPG reduced >=30% (p < 0.01); 15 g CPF alone: not significant
• In a small crossover trial in 11 healthy adults, white bread with chickpea flour only trended toward a lower glucose response (P=0.087) and raised the insulin response compared with white bread. — 11 healthy adults (9 men, 2 women), 50 g available carbohydrate breakfasts (n = 11) Evidence B source
  Glucose IAUC trend lower (P=0.087); insulin IAUC and insulinemic index higher (P<0.05); no change in GI, satiety or intake

Who this works differently for

• Records from a London children's allergy clinic suggest chickpea allergy is outgrown slowly, with 19.3% resolved by age 15. — 203 children aged 5-15 years with IgE-mediated non-priority legume allergy, Evelina London Children's Hospital (n = 203) Evidence C source
  Chickpea allergy resolution 4.9% by age 5, 8.8% by age 10, 19.3% by age 15
• In 55 Italian children with legume allergy, co-allergy among pea, lentil and chickpea was frequent (56 to 86%). — 55 children under 18 years with IgE-mediated legume allergy, single center in Italy, 2022-2024 (n = 55) Evidence C source
  Multi-legume allergy 74.5%; co-allergy among pea, lentil and chickpea 56-86%

What is still unknown

• A scoping review of 47 studies found research on chickpea and other non-priority legume allergies focused on prevalence, with no studies on allergen labeling or education. — 47 original studies on chickpea, pea, lentil and lupine allergy (n = 47) Evidence C source

The bottom line

What ordinary chickpea flour gives for certain is its make-up. Per 100 g, USDA lists 22.4 g protein, 437 mcg folate (109% of the Daily Value) and 0.91 mg copper, from a single reference record with no spread across samples. The one trial longer than a single meal ran for 5 weeks in 27 adults. A diet with whole chickpeas and baked goods made with 30% chickpea flour lowered total cholesterol by 9.7 mg/dL (0.25 mmol/L) and LDL cholesterol by 7.7 mg/dL (0.20 mmol/L) against a wheat diet matched for fiber. The authors put part of that down to a change in the fats people ate. Glucose tolerance did not change. The rest are tests of one meal. In 56 healthy Indian adults, flatbread with 15% chickpea flour plus 3 or 4% guar gum cut the glucose response by at least 15% and insulin by at least 28%, an effect of the mixture. In 12 healthy men, flatbread with chickpea flour and 4% guar gum did not slow glucose absorption, and cut liver glucose output by 64% over 4 hours, mostly through the gum. Corn snacks with 40% chickpea flour lowered blood glucose before the next meal in 26 young adults without changing appetite or how much they ate, and the abstract gives no size for the drop. Pasta with 40% sprouted chickpea flour gave better blood vessel dilation 2 to 3 hours later than semolina pasta in 22 healthy young adults, 10.3% against 7.9%. That is a marker after one meal, with no clinical outcome behind it. Purees of the intact-cell flour raised fullness and lowered hunger in 22 people compared with ordinary chickpea flour, on rating scales, with no size given. In laboratory digestion the same intact-cell flour released its nutrients more slowly than ordinary chickpea flour. For iron the only test is in infants. In 30 Malawian children aged 6 to 14 months, 70% of them anemic, 12.8% of the iron in a fortified cereal of whole wheat and chickpea flour was absorbed, close to the 12.1% from refined wheat and above whole oat cereals. That iron was added to the cereal together with vitamin C at a 2 to 1 molar ratio, so the result says nothing about the iron already in the flour. The chickpea cereal carried one of the highest phytate to iron ratios in the trial, 1.96 to 1. In UK diet surveys the share of people eating chickpea foods, chickpea flour among them, doubled from 6.1% in 2008 to 2012 to 12.3% in 2016 to 2019, a figure for chickpeas as a whole. Do not eat the flour raw. The FDA advises never to eat or taste raw flour, dough or batter, in guidance written about grain flours that does not name chickpea flour, so it applies here by analogy. The rest of the safety data are about allergy. In the records of one London children's allergy clinic, among 203 children aged 5 to 15 allergic to legumes such as chickpea, lentil and pea, 4.9% had outgrown a chickpea allergy by age 5 and 19.3% by age 15. In 55 Italian children with legume allergy at a single specialized center, co-allergy among pea, lentil and chickpea ran from 56 to 86%. If your child reacts to pea or lentil, ask the allergist about chickpea flour before trying it. In a French-language registry of 2999 food anaphylaxis cases from 2002 to 2023, chickpeas caused 7. Those are voluntarily reported cases with no population behind them, so the registry gives no rate. A review of 47 studies on these allergies found none on labeling or on teaching families, so read ingredient lists yourself. We found no study of chickpea flour with medicines or in pregnancy, so those questions are open.
