Mesquite Pod Flour
Prosopis spp. · also called Mesquite flour, mesquite meal, algarrobo flour, harina de algarrobo (Spanish)
Mesquite pod flour is a sweet, nutty flour ground from the dried pods of mesquite trees, which are legume-family trees. It is mostly fibre and natural sugar. Online claims about blood sugar rest on test-tube studies; we found no human trial of the flour. The main cautions are to bake or cook it, to ask an allergist if you have legume or mesquite pollen allergy, and to expect nutrition numbers to vary.

About Mesquite Pod Flour
Mesquite pod flour is a sweet, nutty flour made from the dried pods of mesquite trees. It is a food, not a proven remedy. The research is mostly composition and lab work, and we found no human trial.
What it is
Mesquite pod flour is ground from the dried pods of Prosopis (sometimes now called Neltuma) trees, which are legumes. A 2024 review says use of mesquite goes back to native cultures of the Americas, and that the pods and seeds are used for a gluten-free flour added to baking.
There is no USDA entry for it. Published analyses, per 100 g dry matter: one Brazilian species (P. juliflora) had 8.84 g protein, 0.79 g fat, 40.15 g fibre and 52.51 g non-reducing sugar; another study reported 19.9% fibre. Species, pod part and method change the numbers a lot, so we give no per-serving values.
What the research shows
The firmest facts are about composition: a sweet, fibre-rich flour with no measurable starch.
In test tubes, peptides and extracts from pod flour slowed enzymes that digest sugar and showed antioxidant activity. Those are lab results. We found no human trial of mesquite flour on blood sugar, cholesterol, weight or anything else. Baking studies show the flour darkens and firms bread and muffins.
Rat studies from an old chapter found some amino acids limiting. Reviews describe potential, not proven health effects.

Isolated compounds versus whole extracts
Almost all biological findings come from extracts, isolated peptides or test-tube assays, which are not the same as eating baked goods made with some mesquite flour. The same goes for syrup, gum and leaf tea.
Nutritional composition
There is no USDA FoodData Central entry for mesquite pod flour in the files used for the existing summary, so no official per-100-g values or per-portion values are given here and none are estimated. Published analyses, all per 100 g dry matter unless noted: P. juliflora whole-pod flour from Brazil (2008) had 8.84 g protein, 0.79 g fat, 40.15 g dietary fibre and 52.51 g non-reducing sugar; P. nigra had 11.33 g protein. A 2021 study of a mesquite whole-pod flour reported 19.9% fibre, and calcium, potassium and magnesium were present (amounts not in the abstract). Values differ because of species, pod part and method. Dry matter values are not the same as values for the flour as sold.

Fibre and natural sugar (composition)
Low certaintyPublished lab analyses of mesquite pod flour report a lot of fibre, a lot of natural sugar and no measurable starch. The numbers differ between species and between studies. These are food-analysis facts, not trials in people.
4 studiesFlour made from the whole pod; flours made from the seed or pod wall …
Studies, doses and limits
What the trials found
Whole-pod flour of P. juliflora had 40.15 g dietary fibre and 52.51 g non-reducing sugar per 100 g dry matter (2008 analysis). A mesquite flour in a 2021 study had 19.9% fibre. An FAO-hosted chapter found no starch in P. juliflora pod flour.
Results
The flour is fibre-rich and sweet. Starch was not found. No source we read gives an official nutrition table, and the species compared give different values.
Effect sizes as reported
P. juliflora whole-pod flour: fibre 40.15 g, protein 8.84 g, fat 0.79 g, non-reducing sugar 52.51 g per 100 g dry matter (2008). Another study: fibre 19.9% (2021).
Why this rating
Several lab analyses agree the flour is fibre- and sugar-rich, but values differ widely and there is no USDA entry. No human trial.
Form and dose studied
Flour made from the whole pod; flours made from the seed or pod wall alone are different.
Limits
Different species, parts of the pod and methods give different numbers. Amounts are per 100 g dry matter, not per serving.
Why researchers looked
The flour is sold as a sweet, fibre-rich, gluten-free flour, so people ask what is in it.
Traditional use
Mesquite pods were eaten for centuries in the Americas. Long use as food is not proof that it treats any condition.
Proposed mechanism Not applicable
Not applicable: this is composition, not an effect.
A proposed mechanism does not show that the effect happens in people.
None specific. At about half sugar the flour adds sugar to a recipe.
Plant compounds and antioxidant activity (lab)
Very low certaintyLab tests found phenolic compounds and antioxidant activity in mesquite pod flour and pods. This was measured in test tubes. It does not show that eating the flour has an effect in people.
3 studiesFlour, flour extracts and peptide hydrolysates, as tested in the lab …
Studies, doses and limits
What the trials found
A 2021 study measured 474.77 mg GAE/g polyphenols and higher antioxidant capacity in mesquite flour than in green bean and pea flours. A 2026 study identified rosmarinic, ferulic, p-coumaric, gallic and ellagic acids in pod extracts, and anthocyanins in pigmented pods. A 2022 review says antioxidant effects were seen with extracts and that heating and phenolic content affect how well compounds are absorbed.
Results
Antioxidant activity was found in the lab. No study read tested whether eating the flour changes antioxidant markers in people.
Effect sizes as reported
Polyphenols 474.77 mg GAE/g (2021 flour analysis); antioxidant IC50 1.13 mg/mL (peptides, 2026 test tube).
Why this rating
Lab measurements only; no human outcome.
Form and dose studied
Flour, flour extracts and peptide hydrolysates, as tested in the lab (not the food as eaten).
Limits
Test-tube results do not predict effects in people.
Why researchers looked
Dark, tannin-rich plant foods often contain phenolic compounds, so researchers measure them.
Traditional use
Mesquite pods were eaten for centuries in the Americas. Long use as food is not proof that it treats any condition.
Proposed mechanism Laboratory research
Phenolic compounds and peptides measured in the lab (test tube).
A proposed mechanism does not show that the effect happens in people.
None specific.
Blood sugar (lab only; no human trial found)
Not enough evidenceLab tests found that extracts and protein pieces from mesquite pods slowed sugar-digesting enzymes. We found no human trial of mesquite flour on blood sugar. The flour is itself about half sugar by one analysis.
4 studiesExtracts and peptide hydrolysates, not the flour as eaten.
Studies, doses and limits
What the trials found
The 2026 study blocked alpha-glucosidase with peptides (IC50 5.86 mg/mL) and pod extracts (IC50 1.05 and 0.74 mg/mL), and used computer docking for alpha-amylase. A 2024 review reports potential but no clinical outcomes in the abstract.
Results
No result in people. No source we read supports claims of a proven effect or of a low glycaemic index for the flour.
Effect sizes as reported
Lab IC50 values only.
Why this rating
Test-tube and computer work only; no human or animal outcome.
Form and dose studied
Extracts and peptide hydrolysates, not the flour as eaten.
Limits
The flour is about half sugar by one analysis, so it should not be treated as a diabetes remedy.
Why researchers looked
Online claims say mesquite flour is good for blood sugar, so people ask whether trials back it.
Traditional use
Mesquite pods were eaten for centuries in the Americas. Long use as food is not proof that it treats any condition.
Proposed mechanism Laboratory research
In test tubes, pod extracts and peptides blocked alpha-glucosidase and alpha-amylase, enzymes that break down sugars.
A proposed mechanism does not show that the effect happens in people.
People with diabetes who change what they eat should ask their clinician or dietitian.
Protein quality
Very low certaintyMesquite pod flour has some protein, but old rat studies found the amino acids lysine, threonine and the sulfur amino acids to be limiting. The protein digested at about two-thirds in a lab test.
2 studiesWhole-pod flour.
Studies, doses and limits
What the trials found
P. juliflora whole-pod flour had 8.84 g crude protein per 100 g dry matter and in vitro protein digestibility of 66.45% (2008). An FAO-hosted chapter found lysine, threonine and methionine plus cysteine were the first, second and third limiting amino acids, and tested protein quality in rats.
Results
The protein is modest and not a complete match to needs. No human protein-quality study was found.
Effect sizes as reported
Protein 8.84 g per 100 g dry matter; digestibility 66.45% (in vitro).
Why this rating
Lab and rat studies; one old chapter.
Form and dose studied
Whole-pod flour.
Who was studied
Rats; no people.
Limits
Old rat data and a lab digestion test do not show what happens in people.
Why researchers looked
Pod flour is sometimes described as a protein source.
Traditional use
Mesquite pods were eaten for centuries in the Americas. Long use as food is not proof that it treats any condition.
Proposed mechanism Not applicable
Not applicable (amino acid analysis).
A proposed mechanism does not show that the effect happens in people.
None specific.
Baking use and gluten-free flour
Not enough evidenceMesquite flour can be baked into bread and muffins. It darkens and firms the product. A review calls the flour gluten-free. This is about baking, not health.
3 studiesMesquite flour blended with wheat flour.
Studies, doses and limits
What the trials found
A 2023 muffin study used 10%, 25% and 50% mesquite flour with wheat flour: more mesquite changed colour and taste and raised hardness, and the 75:25 muffin had more protein and fibre and less fat. A 2021 study found bread with mesquite flour had more fibre and only 7% less volume. A 2024 review calls the flour gluten-free.
Results
Works in baking at modest amounts in the studies. No study we read tested cross-contact with gluten in mills or celiac patients.
Effect sizes as reported
Muffin blends 90:10, 75:25, 50:50 (study detail, not advice); bread volume down 7%.
Why this rating
Baking and sensory results are not a health outcome.
Form and dose studied
Mesquite flour blended with wheat flour.
Limits
Baking studies only. Gluten-free status is from a review; cross-contact in mills was not read.
Why researchers looked
The flour is used as a gluten-free and wheat-flour add-in.
Traditional use
Mesquite pods were eaten for centuries in the Americas. Long use as food is not proof that it treats any condition.
Proposed mechanism Not applicable
Not applicable (food technology).
A proposed mechanism does not show that the effect happens in people.
People with celiac disease should look for a gluten-free label.
Heart, weight and other human health outcomes
Not enough evidenceWe found no human trial of mesquite pod flour on blood pressure, cholesterol, weight, gut health or any other health outcome.
2 studiesNot applicable.
Studies, doses and limits
What the trials found
The 2024 and 2022 reviews describe composition and lab or animal properties of Prosopis but the abstracts report no clinical outcomes.
Results
No human health outcome has been tested for the flour.
Why this rating
No trial found.
Limits
Nothing to judge benefit from.
Why researchers looked
Health claims online go well beyond the research.
Traditional use
Mesquite pods were eaten for centuries in the Americas. Long use as food is not proof that it treats any condition.

Evidence at a glance: what the research found for 6 outcomes
Each outcome below is one thing researchers measured. Certainty is how far the evidence can be trusted, not how well it works. The full studies are on the next tab.
The evidence
The research centre for Mesquite Pod Flour. 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 mesquite pod flour summary and re-opened every source it cites: PubMed abstracts, an FAO-hosted chapter and MedlinePlus. Only abstracts were read for journal studies. This is a short page because the research is limited. Items we could not verify are flagged in the research gaps.

Says Prosopis could be a diet rich in fibre, minerals, galactomannans and low in fat, but that antinutritional compounds lower nutritional quality and can be reduced by heating, and that bioavailability of plant compounds is affected by phenolics.

What we do not know yet
- No human trial of mesquite pod flour on any health outcome was found.
- No official nutrition values; published values differ several-fold between species and pod parts.
- Allergy to the flour itself, mould and aflatoxin, kidney disease, medicines, pregnancy, breastfeeding and children were not found in any source read.
- The CDC raw flour page could not be opened, so a UK government laboratory survey is used for flour hygiene.
How new research is added
New studies are found by a saved PubMed search and placed in a review queue before the page changes.
Lab markers
What changed in blood or saliva tests during trials. A changed number is not the same as feeling or being healthier, and we give no "normal ranges".
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 4
- Allergy: pollen is a known allergen; the flour is not studied. Mesquite pollen causes allergy in some people: a lab study used blood serum from 11 mesquite-sensitive patients and found 24 proteins that their IgE antibodies recognised. That study is about pollen, not the food. We found no source on reactions to mesquite flour or on cross-reaction with peanut, soy or other legumes. MedlinePlus says people can be allergic to more than one food and that anaphylaxis is a medical emergency. For trouble breathing or swelling of the face or throat, call emergency services. Laboratory research 5 10
- Raw pods contain a trypsin inhibitor. Raw pod extract of Prosopis juliflora had trypsin inhibitor activity (a protein that blocks a digestive enzyme). In the FAO-hosted chapter heating removed it completely. A species comparison found trypsin inhibitors below those of raw soy. We did not read how commercial flours are heated, so check the label and use the flour in cooked or baked foods. Laboratory 9 3 8
- Raw flour can carry germs. A UK government laboratory survey of 882 raw flours found Salmonella in 0.1% and Shiga-toxin-producing E. coli in 0.8%. Mesquite flour was not singled out. Bake or cook flour dishes and do not taste raw batter. Survey 6
- Very little safety research on this food. We found no safety study of mesquite pod flour in people, and no source on aflatoxin or mould in pods or flour, kidney disease, medicines, pregnancy or children. Nitrates and phytate were higher than in some other legumes in one lab comparison, but what this means for people was not stated. None found 3
Side effects 2
| Effect | How often | Severity and recovery | Evidence |
|---|---|---|---|
| Constipation reported by some tasters of extruded pod-flour products One old chapter says some people who tasted the products reported constipation and the authors asked for investigation. Not a controlled finding. | Not given | not stated Not studied | Anecdotal 9 |
| Allergic reaction to mesquite (pollen allergy in sensitive people) Pollen study only. No report of food allergy to the flour was found. | Not given | can be severe in any food allergy Not studied | Laboratory research 5 |
Medicines and supplements 2
| With | Why it matters | Importance | Evidence | What to do |
|---|---|---|---|---|
| Diabetes medicines prescription | Pod extracts blocked sugar-digesting enzymes in test tubes, and the flour is about half sugar by one analysis. | No source tied the flour to a medicine interaction. This is a general caution only. | Theoretical Not enough evidence 7 3 | Ask your clinician or pharmacist before big diet changes if you take medicine for blood sugar. |
| Medicines in general prescription | No interaction study of mesquite flour was found. | None found Not enough evidence | Ask a pharmacist if unsure. |
Who should check first 1
Overdose, product quality and regulators
Summary. No toxicity from cooked or baked mesquite flour as ordinary food was found in the sources read, but there are almost no safety studies of the flour.
Animal. Rat feeding trials are described in an old FAO-hosted chapter; details were not used.
Human doses studied. Bakery trials used blends with wheat flour (5% and 10% pod flour in an FAO-hosted chapter; 10% to 50% in a 2023 muffin study). Study detail, not advice.
Overdose response. Not found.
Genotoxicity. Not researched.
Toxic or hazardous parts. Raw pods: trypsin inhibitor, removed by heating in one study.
Flour in general can carry Salmonella and Shiga-toxin E. coli. Mould, aflatoxin and heavy metals in mesquite pods or flour were not researched.
Germs in raw flour. UK survey of 882 flours: Salmonella 0.1%, Shiga-toxin E. coli 0.8%, generic E. coli above 20 CFU/g in 7.7%. Mesquite flour was not singled out. 6
Species and pod part. Whole-pod flour differs from flours made from the seed or pod wall, and species differ several-fold in composition. 3 4

When to get medical help
- Trouble breathing, swelling of the lips, face or throat, widespread hives, repeated vomiting or collapse after eating mesquite flour (possible anaphylaxis): call emergency services
Stop using the product and contact a clinician or emergency service. In the US, Poison Control is 1-800-222-1222.
General information only, not medical advice. Ask a clinician or pharmacist before use, especially with medicines, in pregnancy or with a health condition. See the Natural Remedy Safety guide.
Frequently asked questions
What is mesquite pod flour?
It is a sweet, nutty flour ground from the dried pods of mesquite trees (Prosopis, sometimes called Neltuma), which belong to the legume family. A 2024 review says it is used as a gluten-free flour in baking.
Does mesquite flour lower blood sugar?
Is mesquite flour gluten-free?
Mesquite is not a gluten grain, and a 2024 review calls the flour gluten-free. We did not read a source on cross-contact in mills, so people with celiac disease should look for a gluten-free label.
Is it safe to eat raw?
Why do nutrition numbers differ between sources?
Can mesquite flour cause an allergic reaction?
If I am allergic to peanuts or soy, can I eat it?
Ask an allergist. Peanut and soy are legumes, and MedlinePlus says people may be allergic to more than one food. We found no source on cross-reaction between mesquite flour and other legumes.
Is mesquite flour high in protein?
Does it have antioxidants?
Does mesquite flour cause constipation?
One old chapter says some people who tasted extruded pod-flour products reported constipation, and the authors asked for investigation. It was not a controlled finding.
Is it the same as mesquite extract, gum or syrup?
Is mesquite flour safe in pregnancy or for children?
We did not find a source that covers it. Ask your doctor, midwife or pharmacist, and ask an allergist about any food allergy.

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.
