Chickpea Flour (Besan)
Cicer arietinum · also called Besan, gram flour, garbanzo flour, chickpea flour, harina de garbanzo
Chickpea flour, also called besan or gram flour, is dried chickpeas ground to a fine, pale yellow flour. It is used in flatbreads, pancakes and batters. By USDA data it is rich in plant protein, fibre and folate. Research on the flour itself is very thin: one small bread trial of 15 people, plus studies of whole chickpeas and other legumes. The main cautions are chickpea and other legume allergy, germs in raw flour or batter, gluten-free labelling for people with coeliac disease, and a possible mix-up with toxic grass pea flour.

About Chickpea Flour (Besan)
Chickpea flour (besan) is the whole ground chickpea, rich in protein, fibre and folate. It is a food, not a proven remedy. Almost all the health findings come from whole chickpeas or legumes in general, and the flour has one small bread trial. Cook it fully: raw flour and batter can carry germs.
What it is
Chickpea flour, known as besan or gram flour, is made from dry chickpeas (Cicer arietinum, family Fabaceae per GBIF) ground to a fine, pale yellow flour. Some regions roast the seeds first. It is used in flatbreads, pancakes, batters and fritters.
USDA data for dry chickpea flour, per 100 g: 387 kcal, 22.39 g protein, 6.69 g fat, 57.82 g carbohydrate, 10.8 g fibre, 437 micrograms folate (DFE), 4.86 mg iron, 846 mg potassium, 318 mg phosphorus and 64 mg sodium. One cup (92 g) has about 356 kcal, 20.6 g protein, 9.94 g fibre and 402 micrograms folate. These are values for the dry flour, not for cooked flatbreads or fritters, which add water, oil and other ingredients.
What the research shows
Blood sugar: a 2025 review of 28 single-meal studies (40 comparisons) found a lower blood sugar rise after chickpea foods than after carbohydrate-matched foods. Peak glucose and insulin did not change significantly, and the certainty was very low by GRADE. The authors work for PepsiCo and Biofortis.
Flour: the only flour trial is a 2025 crossover study of 15 healthy adults. Bread with 30% of the wheat flour replaced by large-particle chickpea flour gave a lower glucose rise than white bread, and higher fullness. Bread with finely milled chickpea flour did not differ from white bread. Chickpea pasta that was cooked, cooled and reheated had a glycaemic index of 33 against 39 when fresh, in 12 people. That is a pasta result.
Cholesterol and fasting blood sugar: pooled trials of pulses and legumes found LDL about 0.16 to 0.17 mmol/L lower and fasting glucose 0.18 mmol/L lower. Chickpea flour was not separated out.
Frying, baking and acrylamide
The FDA says acrylamide forms mainly in plant foods cooked at high heat, and that longer cooking and higher temperatures generally mean more. It advises golden rather than dark brown. The FDA page does not mention chickpea flour, batters or fritters, and we found no measurement for them.
Flour versus whole chickpeas and other products
Most blood sugar studies used whole chickpeas, bread or pasta, not plain flour. Hummus, falafel, protein powders and extracts are different products and are not covered here.
Pregnancy and breastfeeding
No advice about chickpea flour in pregnancy or breastfeeding was found. The NHS pregnancy diet page lists beans and pulses as protein foods and advises a folic acid supplement; it does not mention chickpea flour or raw flour. Ask your doctor or midwife.
Amounts
This page gives no amounts to eat. Ask a doctor, pharmacist or dietitian what is right for you, especially if you have a food allergy, coeliac disease or kidney problems.

Isolated compounds versus whole extracts
Chickpea flour is the whole ground seed, so it keeps the fibre and protein. The blood sugar results come from whole chickpeas, a bread made with chickpea flour and a chickpea pasta, not from plain flour on its own. The bread trial shows that milling matters: finely milled flour did not lower glucose, large-particle flour did. Protein powders and extracts are not the flour and were not covered.
Nutritional composition
Nutrition from USDA FoodData Central (SR Legacy, April 2018 release; item 174288 read 2026-10-26 from a saved copy held with the project). DRY CHICKPEA FLOUR, per 100 g: 387 kcal, 22.39 g protein, 6.69 g fat (0.693 g saturated), 57.82 g carbohydrate, 10.85 g total sugars, 10.8 g fibre, 437 micrograms folate (DFE), 4.86 mg iron, 0.912 mg copper, 1.6 mg manganese, 166 mg magnesium, 846 mg potassium, 318 mg phosphorus, 45 mg calcium, 2.81 mg zinc, 64 mg sodium, 0.486 mg thiamin (B1), 0.492 mg vitamin B6 and 39 mg phytosterols. One cup of flour (92 g) is about 356 kcal, 20.6 g protein, 9.94 g fibre, 402 micrograms folate, 4.47 mg iron, 778 mg potassium and 293 mg phosphorus. A cup is a lot of flour for one meal; recipes spread it over several servings. These are the values for the dry flour, not for cooked flatbreads, pancakes or fritters, which add water, oil and other ingredients. Figures vary with variety, growing place and milling.

Blood sugar after a meal (chickpea foods)
Very low certaintyIn small single-meal trials, chickpea foods gave a lower blood sugar rise after eating than matched foods. Plain chickpea flour has not been tested on its own. The best flour result is one small bread trial.
3 studiesFoods eaten at one meal: whole chickpeas, bread with chickpea flour, …
Studies, doses and limits
What the trials found
A 2025 review of 28 acute studies (40 comparisons) of chickpea meals found a lower glucose rise (iAUC) than with carbohydrate-matched foods, but no clear change in peak glucose or insulin. In a 2025 crossover trial of 15 healthy adults, bread with 30% of the wheat flour replaced by large-particle chickpea flour gave a lower glucose rise than white bread and than bread made with finely milled chickpea flour. In 12 healthy adults, chickpea pasta that was cooked, cooled and reheated had a glycaemic index of 33, against 39 when freshly cooked.
Results
Chickpea foods lowered the blood sugar rise after one meal in small studies. The finely milled chickpea flour bread did not differ from white bread. Plain flour was not tested alone.
Effect sizes as reported
Review: glucose iAUC mean difference -47.89 (95% CI -64.20 to -31.58); peak glucose and insulin not significantly changed. Bread trial: glucose iAUC lower for large-particle chickpea bread than for wheat bread (p<0.05). Pasta: GI 33 against 39 (p=0.0022).
Why this rating
The review authors rate glucose iAUC very low by GRADE because the studies differ a lot, and call the overall evidence low to very low. The flour-specific evidence is one trial of 15 people, so we rate it very low. The review was written by employees of PepsiCo and Biofortis.
Form and dose studied
Foods eaten at one meal: whole chickpeas, bread with chickpea flour, chickpea pasta. Trial amounts are not advice.
Who was studied
Mostly healthy adults with normal blood sugar.
Limits
Single meals only, no long-term data, mostly healthy people, and only one trial used chickpea flour (as 30% of a bread). Finely milled flour did not work. It does not show that chickpea flour treats diabetes.
Why researchers looked
Chickpea flour is the whole ground legume, rich in fibre and protein, so researchers ask whether foods made from it change the blood sugar rise after a meal.
Traditional use
Chickpea flour (besan) is eaten as a food, in flatbreads, batters and fritters. Long use as food is not proof that it treats any condition.
Proposed mechanism Unknown
The papers read do not prove a mechanism. The bread authors point to flour particle size and to the gut hormone GLP-1, which was higher after the large-particle bread.
A proposed mechanism does not show that the effect happens in people.
None specific. Raw flour must be cooked; see the Safety tab.
Fullness and appetite after a meal
Very low certaintyIn one small bread trial, large-particle chickpea flour bread left people feeling less hungry and more full than wheat bread. This is a short, single-meal result from 15 people.

Studies, doses and limits
What the trials found
In the 2025 crossover trial of 15 healthy adults, hunger and desire to eat were lower and fullness higher after the large-particle chickpea bread than after wheat bread (visual rating scales). A 2010 review says short meal studies of pulses (not flour) show more fullness for 2 to 4 hours.
Results
More fullness ratings after one test bread, in a small group.
Effect sizes as reported
Hunger and desire to eat lower and fullness higher after large-particle chickpea bread than wheat bread (p<0.05).
Why this rating
One trial of 15 healthy adults, ratings reported by the people themselves, a single meal. The 2010 review is about whole pulses.
Form and dose studied
Bread with 30% of the wheat flour replaced by chickpea flour. Not advice.
Who was studied
Healthy adults.
Limits
Very small, one meal, self-rated hunger. Long-term effects on weight were not shown for the flour.
Why researchers looked
Fibre and protein can slow digestion, so researchers also ask whether chickpea flour foods change hunger.
Traditional use
Chickpea flour (besan) is eaten as a food, in flatbreads, batters and fritters. Long use as food is not proof that it treats any condition.
Proposed mechanism Unknown
The bread authors link the result to a higher GLP-1 response. This is not proven by the abstract.
A proposed mechanism does not show that the effect happens in people.
None specific.
Cholesterol (LDL), pulses and legumes as a group
Low certaintyPooled trials of pulses and legumes found a small fall in LDL cholesterol. Chickpea flour was not tested alone, so this is a group result.
3 studiesWhole pulses and legumes. Trial amounts are not advice.
Studies, doses and limits
What the trials found
A 2014 review of 26 trials (1,037 people) found LDL 0.17 mmol/L lower on diets with about 130 g a day of pulses. A 2024 review of 24 trials (1,938 adults, at least 6 weeks) found LDL 0.16 mmol/L lower, rated moderate certainty by its authors. Harvard cites an 11-trial analysis with LDL about 6% lower.
Results
LDL fell slightly in pooled trials of pulses and legumes. No trial of chickpea flour was found.
Effect sizes as reported
2014: LDL -0.17 mmol/L (95% CI -0.25 to -0.09). 2024: LDL -0.16 mmol/L (-0.24 to -0.08); total cholesterol -0.23 mmol/L.
Why this rating
The 2024 authors rate it moderate for legumes as a whole; for chickpea flour we rate it low because none of the trials used flour and the control foods and legume types varied.
Form and dose studied
Whole pulses and legumes. Trial amounts are not advice.
Who was studied
Adults with and without raised cholesterol.
Limits
Not about flour. Different legumes and forms in each trial; the 2014 pulse effect did not extend to apolipoprotein B or non-HDL cholesterol.
Why researchers looked
Legumes are high in fibre, which is linked to cholesterol, so many trials test pulses.
Traditional use
Chickpea flour (besan) is eaten as a food, in flatbreads, batters and fritters. Long use as food is not proof that it treats any condition.
Proposed mechanism Unknown
Not established. The Harvard page attributes it mainly to soluble fibre, oligosaccharides and phytochemicals.
A proposed mechanism does not show that the effect happens in people.
None specific.
Fasting blood sugar (legumes as a group)
Low certaintyPooled trials of legumes found a small fall in fasting blood glucose. This is not about chickpea flour.
1 studiesLegumes as food. Not advice.
Studies, doses and limits
What the trials found
A 2024 review of 24 trials (1,938 adults, legumes at 86 g a day on average, at least 6 weeks) found fasting glucose 0.18 mmol/L lower, rated moderate certainty by its authors.
Results
A small fall in fasting glucose with legumes in general.
Effect sizes as reported
Fasting glucose -0.18 mmol/L (95% CI -0.30 to -0.06).
Why this rating
Moderate for legumes as a group by the authors; low for chickpea flour because no flour trial was included in what we read.
Form and dose studied
Legumes as food. Not advice.
Who was studied
Adults, with and without conditions.
Limits
Legumes as a group, results differed with the type and form of legume.
Why researchers looked
Legumes are digested slowly, so researchers test whether eating them for weeks changes fasting blood sugar.
Traditional use
Chickpea flour (besan) is eaten as a food, in flatbreads, batters and fritters. Long use as food is not proof that it treats any condition.
Proposed mechanism Unknown
Not established in the abstract.
A proposed mechanism does not show that the effect happens in people.
None specific.
Body weight (pulses as a group)
Very low certaintyA review found pulses may help weight loss when combined with eating less, but not without it. Chickpea flour itself has no weight trial.
1 studiesWhole pulses. Not advice.
Studies, doses and limits
What the trials found
A 2010 review says weight trials of pulses were few and short (3 to 8 weeks for whole pulses) and generally supported weight loss when pulses came with energy restriction, but not without it.
Results
Possible help for weight loss only with eating less; unproven for flour.
Effect sizes as reported
Not given in the abstract.
Why this rating
Old review, few short trials, nothing on flour.
Form and dose studied
Whole pulses. Not advice.
Who was studied
Adults.
Limits
Not about flour. Short trials. Observational links to lower body weight may be confounded, as the authors say.
Why researchers looked
Pulses are high in fibre and protein, so they are studied for weight.
Traditional use
Chickpea flour (besan) is eaten as a food, in flatbreads, batters and fritters. Long use as food is not proof that it treats any condition.
Proposed mechanism Unknown
The review points to slowly digested carbohydrate, fibre and protein.
A proposed mechanism does not show that the effect happens in people.
None specific.
Folate, plant protein, fibre, copper and manganese
High certaintyChickpea flour is a rich source of folate, plant protein, fibre, copper and manganese by USDA data. This is a nutrient fact, not a trial of health benefits.
1 studiesDry flour, USDA values per 100 g and per cup.
Studies, doses and limits
What the trials found
USDA FoodData Central lists, per 100 g of dry flour: 22.39 g protein, 10.8 g fibre, 437 micrograms folate (DFE, 109% of the Daily Value), 0.912 mg copper, 1.6 mg manganese and 4.86 mg iron. One cup (92 g) gives about 20.6 g protein, 9.94 g fibre and 402 micrograms folate.
Results
A nutrient-dense dry flour. Values describe the dry flour, not cooked flatbreads or fritters.
Why this rating
Composition values come from a national database; they say what is in the flour, not what it does for health.
Form and dose studied
Dry flour, USDA values per 100 g and per cup.
Limits
Values vary with variety, growing place and milling. Cooking changes what is left and adds other ingredients.
Why researchers looked
The flour is the whole ground legume, so it keeps the seed nutrients.
Traditional use
Chickpea flour (besan) is eaten as a food, in flatbreads, batters and fritters. Long use as food is not proof that it treats any condition.
Proposed mechanism Unknown
Not applicable. These are food composition values.
A proposed mechanism does not show that the effect happens in people.
None specific. See the Safety tab for allergy and raw flour.

The evidence
The research centre for Chickpea Flour (Besan). Every record here was checked against PubMed or the publisher's page; we never list a study we have not verified.
Evidence by outcome
Bars show how many studies we found for each outcome, not how well it works. People are added up across trials only (reviews are not added, to avoid double counting).
How we rate evidence
High certainty
Several well-run trials or reviews agree; further research is unlikely to change the picture much.
Moderate certainty
Good trials point the same way, but some doubt remains.
Low certainty
Small, short or inconsistent trials. The finding could change with better research.
Very low certainty
Very little or very weak human data. Treat as a possibility only.
Mixed findings
Trials or reviews disagree with each other.
Not enough evidence
Not enough human research to say either way.
Evidence against
Good research found no benefit, or found harm.
We take the reviewers' own risk-of-bias and GRADE statements where they exist, and otherwise judge from study size, design, consistency, directness and whether a product matches what is sold. Many publications do not make evidence high. Method note: We started from our existing chickpea flour nutrient summary, took nutrition from USDA FoodData Central, read agency pages (CDC, FDA, MedlinePlus, NHS, Harvard Nutrition Source) and searched PubMed for reviews, trials and safety studies. Only abstracts were read for studies. Items we could not verify are flagged in the research gaps.

Review of allergy to non-priority legumes | Not applicable (allergy review) Seed |
Beans, pea, lentil, chickpea, lupine and other legumes can cause mild to severe allergic reactions. Severe reactions are described particularly for pea and lupine. Exercise-linked anaphylaxis has been highlighted for soybean, lentil and chickpea. Most reactions come from cross-reacting IgE to similar proteins. Most studies are case reports. Not applicable (Not applicable) Methods, limits and fundingOutcomes: Allergic reactions to legumes Limitations: Mostly case reports, so it cannot say how common chickpea allergy is. It does not discuss chickpea flour. Funding and conflicts: The authors declare no conflict of interest. Read: abstract |

Safety
What studies and official sources say about side effects, medicines and who should check first. Each point shows what kind of evidence it comes from.
Main points to know 5
- Raw flour can carry germs: cook or bake it fully. The CDC says most flour is raw and not treated to kill germs such as E. coli and Salmonella. Grinding does not remove them, and germs are killed only when flour is baked or cooked. Do not eat raw batter or dough, and do not taste raw flour. We found no measurement for chickpea flour specifically. Authoritative guidance 13 6 10
- Chickpea and other legume allergy can be severe. Chickpea is a legume, and allergy to it is reported, from mild reactions to anaphylaxis. A 2024 review describes exercise-linked anaphylaxis with chickpea in case reports. In a 2026 Italian clinic study of 55 children with legume allergy, most were allergic to more than one legume and 25.5% also had peanut allergy. Chickpea is not on MedlinePlus list of major food allergens. For trouble breathing or swelling of the face or throat, call emergency services. Observational 1 11 18
- Check what is in the bag: grass pea flour is a different, toxic flour. Grass pea (Lathyrus sativus) flour carries a nerve toxin (beta-ODAP) linked to neurolathyrism, a disease with stiff, weak legs. A 2026 Ethiopian survey found 11.9% of 470 people reporting it. We did not find a source read that says how often grass pea is mixed into besan, so we cannot say how common this is. Observational 9 12
- Gluten-free only if the label says so. Chickpeas are not wheat, rye or barley. The FDA says a gluten-free label means under 20 parts per million of gluten. We found no source on gluten cross-contact in chickpea flour mills, so people with coeliac disease should choose flour labelled gluten-free. Authoritative guidance 15
- Gas and bloating in some people. Legumes contain resistant starch and oligosaccharides that gut bacteria ferment, which can cause gas, bloating and cramps in some people (Harvard Nutrition Source). No measurement for chickpea flour was found. Authoritative guidance 17
Side effects 3
| Effect | How often | Severity and recovery | Evidence |
|---|---|---|---|
| Food poisoning from eating raw flour, dough or batter The home-oven heating study tested wheat-based and gluten-free flours, not legume flour, and none of its home methods reached the 5-log kill it aimed for. | In a UK survey of 882 raw flour products, Salmonella was found in 0.1% and Shiga-toxin-producing E. coli in 0.8%. No chickpea-flour figure was found. | can be serious Not assessed here | Authoritative guidance 13 6 |
| Allergic reactions to chickpea, from mild symptoms to anaphylaxis Clinic studies and case reports of people already allergic. They do not show how common chickpea allergy is, and neither discusses flour. | Not known for the general population. Co-allergy among pea, lentil and chickpea was 56 to 86% in 55 Italian children with legume allergy. | can be severe (anaphylaxis) Not assessed here | Observational 1 11 |
| Gas, bloating and cramps Harvard Nutrition Source describes this for legumes in general. | Not measured for chickpea flour. | mild, in some people Not assessed here | Authoritative guidance 17 |
Liver
No liver injury from eating chickpea flour was found in the sources read. A liver-safety database such as LiverTox was not searched for this page.
How often. No frequency was found.
Monitoring. No agency monitoring advice was found.
This is a safety connection. It is not evidence that Chickpea Flour (Besan) supports liver health.
Medicines and supplements 1
| With | Why it matters | Importance | Evidence | What to do |
|---|---|---|---|---|
| Medicines that raise blood potassium (ACE inhibitors, angiotensin II receptor blockers, potassium-sparing diuretics) and kidney disease prescription | MedlinePlus lists these medicines among causes of high blood potassium and says people with kidney problems, particularly on dialysis, should not eat too many potassium-rich foods. USDA lists 846 mg of potassium in 100 g of the dry flour. | MedlinePlus does not name chickpea flour; the link is our reading of two separate facts. Ordinary food amounts are not known to be a problem for most people. | Authoritative guidance Low certainty 19 21 | If you have kidney disease or take one of these medicines, ask your kidney team, doctor or pharmacist about potassium-rich foods. |
Who should check first 4
| Situation | Advice | Evidence |
|---|---|---|
| Known or suspected chickpea or other legume allergy | Avoid chickpea flour until an allergist has advised you. For trouble breathing or swelling of the face or throat, call emergency services. | Observational 1 11 18 |
| Coeliac disease or a medical gluten-free diet | Choose chickpea flour that is labelled gluten-free, because the label is the only guide we found. | Authoritative guidance 15 |
| Raw batter, dough or flour eaten as is | Do not eat it raw. Cook or bake it fully. | Authoritative guidance 13 |
| Kidney disease with a potassium or phosphorus limit | Ask your kidney team before using a lot of this flour. | Authoritative guidance 19 21 |
Overdose, product quality and regulators
Summary. No toxicity from pure chickpea flour, cooked, was found in the sources read. The cautions are germs in raw flour, allergy, and possible mix-ups with grass pea flour.
Animal. Not reviewed.
Overdose response. Not found.
Genotoxicity. Not researched.
Toxic or hazardous parts. Chickpea flour: none found. Grass pea (Lathyrus sativus) is a different plant whose flour carries the toxin beta-ODAP.
Raw flour can carry bacteria. Grass pea flour is a possible adulterant; how often is unknown. Acrylamide can form when starchy foods are fried or baked at high heat, but no figure for chickpea-flour foods was found.
Bacteria in raw flour. CDC: most flour is raw and not treated to kill germs; baking or cooking kills them. A UK survey of 882 flour products found Salmonella in 0.1% and STEC in 0.8%. Home oven heating of wheat-based and gluten-free flours did not reach a 5-log Salmonella reduction in a 2026 laboratory study (no legume flour tested). 13 6 10
Grass pea mix-up. Grass pea flour carries beta-ODAP. A 2024 analysis of six grass pea flours found 0.086% to 0.49%; the authors cite 0.15% as a safe level. How often grass pea is mixed into besan was not found. 9 12
Acrylamide in fried or baked foods. The FDA says acrylamide forms mainly in plant foods cooked at high heat and that longer cooking and higher temperatures generally mean more. For potato products it advises golden yellow rather than brown, and for bread a light brown rather than dark brown. The FDA page does not mention chickpea flour, batters or fritters, and we found no measurement for them. 14

When to get medical help
- Trouble breathing, swelling of the lips, face or throat, widespread hives, repeated vomiting or collapse after eating chickpea flour foods (possible anaphylaxis): call emergency services.
- Vomiting, diarrhoea, stomach pain or fever after eating foods made with raw or undercooked flour: seek medical care if severe or lasting.
- Weakness or stiffness of the legs that develops over time in someone who eats a lot of a flour that may contain grass pea: see a doctor.
Stop using the product and contact a clinician or emergency service. In the US, Poison Control is 1-800-222-1222.

Frequently asked questions
What is chickpea flour good for?
Does chickpea flour help with blood sugar?
Does chickpea flour lower cholesterol?
Does chickpea flour help with weight loss or fullness?
Is it safe to eat raw chickpea flour or batter?
Can I make raw flour safe in a home oven?
A 2026 laboratory study heated wheat-based and gluten-free flours in a home oven and none of the home methods reached the 5-log germ reduction it aimed for. Legume flour was not tested. Cooking the finished food fully is the safer route.
Can you be allergic to chickpea flour?
If I am allergic to peanuts, can I eat besan?
Is chickpea flour gluten-free?
Chickpeas are not wheat, rye or barley. We found no source on cross-contact in mills, so people with coeliac disease should choose flour labelled gluten-free. The FDA defines that as under 20 parts per million of gluten.
What is the grass pea warning about besan?
Does frying chickpea flour batter make acrylamide?
The FDA says acrylamide forms in plant foods cooked at high heat and advises golden rather than dark brown. It does not name chickpea flour, and no measurement for fritters was found.

Where to buy
Check the label first. Whatever you buy, look for these:
- A recent packed-on date: very old dried beans cook unevenly
- Organic or not, and the country of origin
- Whether you want dried or canned
- Soak and cook thoroughly; some raw beans are unsafe
Talk to a pharmacist or doctor before you start any supplement, especially if you take medicines. See the Safety tab for interactions.
