Farro
Triticum dicoccum · also called Emmer, emmer wheat, farro (Italian)
Farro is the Italian shop name for emmer, a hulled ancient wheat, eaten cooked as chewy grains in soups and salads. Research on farro itself is very thin: reviews say human trials are too few to show ancient wheats are healthier than modern wheat. Heart findings come from whole grains in general. The main caution is that farro is wheat and contains gluten, so it is not safe with celiac disease or wheat allergy.

About Farro
Farro is emmer, a hulled ancient wheat eaten as cooked grains. It is wheat, so it contains gluten. It is a whole-grain food, not a proven remedy: very little research looks at farro itself.
What it is
Farro is the Italian name used in shops for hulled ancient wheats. Here it means emmer, whose husk is removed before eating. Packs can also use farro for einkorn or spelt, and we did not read a source that sets the naming rules, so check the label. Pearled or semi-pearled farro has had some or all bran removed.
We give no nutrient table. USDA FoodData Central was rate-limited when checked for this page, the earlier page said it held no farro entry, and we did not find a peer-reviewed table of emmer values.
What the research shows
No trial of eating farro alone was found. A 2018 review of lab, animal and human studies of ancient wheats says human trials are too few to say they beat modern wheat. A 2022 review found ancient wheats contain more protein and gluten, not less.
Whole grains as a group are better studied: cohort studies link them to less heart disease and a pooled set of trials found a small LDL drop, but these are not farro-specific. One small trial of ancient-wheat pasta in 20 healthy adults changed gut bacteria; the health meaning is unclear.
Food versus flour and extracts
The pasta trial used semi-whole ancient-wheat pasta and the lab study used flours and pasta. No farro extract or supplement trial was found, and none is covered here.
Portions
The NHS advises choosing wholegrain starchy foods where you can, with starchy foods making up just over a third of the diet. This page gives no amounts to eat. Ask a doctor, pharmacist or dietitian what is right for you, especially with celiac disease, wheat allergy or kidney disease.

Isolated compounds versus whole extracts
Everything here concerns farro or ancient wheat as food (grain, flour or pasta). The gluten trial used purified gluten. No farro extract or supplement trial was found, and none is covered.
Nutritional composition
No nutrient table is given. USDA FoodData Central could not be queried for this build (the public key was rate-limited), the earlier farro page said USDA held no farro or emmer entry, and no peer-reviewed table of emmer values was read. What the sources we read do say: ancient wheats contain more protein and gluten than modern bread wheat (2022 review), and emmer scored better than common and durum wheat on some essential amino acids while lysine and histidine stayed limiting (2026 lab study). Pearled or semi-pearled farro has had bran removed, which lowers fibre; the size of the loss was not read. The NHS advises choosing wholegrain starchy foods where you can. Other grains such as spelt and khorasan wheat have their own pages, but their numbers are not farro numbers.

Better than modern wheat? (ancient wheats)
Not enough evidenceAncient wheats such as emmer are often described as healthier than modern wheat. A review of lab, animal and human studies found some support in animal experiments, but too few human trials to say they are better.
2 studiesFarro grain as food. Supplements and extracts were not found or read.
Studies, doses and limits
What the trials found
A 2018 review of in vitro, ex vivo, animal and human studies of emmer, einkorn, spelt, khorasan and regional Italian wheats found some lab support for healthier profiles and benefits on lipid, glucose, inflammation and oxidative markers in in vivo experiments. Because of the limited number of human trials it is not possible to conclude ancient wheats beat modern ones at reducing chronic disease risk. A 2022 review adds that ancient wheats contain more protein and gluten than bread wheat.
Results
No clear human benefit over modern wheat has been shown.
Effect sizes as reported
No pooled effect sizes.
Why this rating
Mostly lab and animal work and a handful of human trials; emmer is mixed in with other ancient wheats.
Form and dose studied
Farro grain as food. Supplements and extracts were not found or read.
Who was studied
Adults in the few human trials
Limits
The reviews do not separate emmer from einkorn, spelt and khorasan.
Why researchers looked
Farro is sold as an "ancient grain", so people ask whether it is healthier than ordinary wheat.
Traditional use
Farro is eaten cooked in soups, salads and side dishes. Long use as food is not proof that it treats any condition.
Proposed mechanism Laboratory research
Not established. Lab studies on antioxidant content are mixed.
A proposed mechanism does not show that the effect happens in people.
Farro contains gluten (see Safety tab).
Heart disease and death (whole grains as a group)
Low certaintyIn studies that follow people over time, people who ate more whole grains had less heart disease and lived longer. This is about whole grains in general, not farro, and it cannot prove cause.
1 studiesFarro grain as food. Supplements and extracts were not found or read.
Studies, doses and limits
What the trials found
A 2016 meta-analysis of 45 prospective studies found that for each extra 90 g a day of whole grains, coronary heart disease risk was RR 0.81 (95% CI 0.75 to 0.87), cardiovascular disease RR 0.78 (0.73 to 0.85) and death from any cause RR 0.83 (0.77 to 0.90). Stroke was not clearly lower (RR 0.88, 0.75 to 1.03). There was little evidence of a link for refined grains or white rice.
Results
Higher whole-grain intake went with lower heart disease and death risk in cohort studies. Farro was not studied alone.
Effect sizes as reported
CHD RR 0.81; CVD RR 0.78; stroke RR 0.88; all-cause death RR 0.83 (per 90 g a day).
Why this rating
Observational only, and whole grains as a group (bread, cereals, bran). We found no study of farro.
Form and dose studied
Farro grain as food. Supplements and extracts were not found or read.
Who was studied
Adults in cohort studies
Limits
People who eat more whole grains may differ in other healthy habits.
Why researchers looked
Large studies ask whether people who eat more whole grains get heart disease less often.
Traditional use
Farro is eaten cooked in soups, salads and side dishes. Long use as food is not proof that it treats any condition.
Proposed mechanism Unknown
Not established. The studies are observational.
A proposed mechanism does not show that the effect happens in people.
Farro contains gluten (see Safety tab).
Cholesterol (whole-grain diets)
Low certaintyTrials of whole-grain foods found a small drop in LDL ("bad") cholesterol compared with non-whole-grain foods. Oats worked best. Farro was not tested alone.
1 studiesFarro grain as food. Supplements and extracts were not found or read.
Studies, doses and limits
What the trials found
A 2015 meta-analysis of 24 randomised studies in healthy adults found whole-grain foods lowered LDL cholesterol by 0.09 mmol/L (95% CI 0.15 to 0.03 lower) and total cholesterol by 0.12 mmol/L (0.19 to 0.05 lower) versus non-whole-grain controls, with no effect on HDL. Whole-grain oat had the greatest effect on total cholesterol.
Results
A small fall in LDL with whole-grain diets as a group. Not specific to farro.
Effect sizes as reported
LDL -0.09 mmol/L; total cholesterol -0.12 mmol/L.
Why this rating
Randomised trials, but the effect is small, LDL is a marker not a heart attack count, and farro was not singled out.
Form and dose studied
Farro grain as food. Supplements and extracts were not found or read.
Who was studied
Healthy adults in trials
Limits
Whole grains as a group; oats had the largest effect.
Why researchers looked
Whole grains contain fibre, so researchers test whether they change blood fats.
Traditional use
Farro is eaten cooked in soups, salads and side dishes. 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.
Gut bacteria (ancient wheat pasta)
Not enough evidenceIn a small trial of 20 healthy adults, eating pasta made from ancient wheat for 8 weeks changed gut bacteria and some gut fatty acids, but so did modern wheat pasta. What this means for health is not clear.
1 studiesFarro grain as food. Supplements and extracts were not found or read.
Studies, doses and limits
What the trials found
A 2022 randomised, double-blind crossover trial of 20 healthy adults compared 8 weeks of semi-whole organic ancient-wheat pasta with modern-wheat pasta. Both changed gut bacteria only at genus level, with different patterns. Ancient-wheat pasta raised stool acetic (+0.7%), isobutyric (+30.1%), 2-methylbutyric (+64.2%) and isovaleric (+22.5%) acids; modern-wheat pasta lowered butyric (-31.6%) and hexanoic (-66.4%) acids.
Results
Different gut-bacteria patterns with each pasta. No health benefit was measured.
Effect sizes as reported
See human evidence.
Why this rating
One small trial in healthy adults; the abstract does not say the wheat was emmer alone; no health outcome.
Form and dose studied
Farro grain as food. Supplements and extracts were not found or read.
Who was studied
Healthy adults, mean age 43
Limits
Pasta, not intact farro grains. Gut bacteria changes are not the same as a health benefit.
Why researchers looked
Gut bacteria respond to the fibre and other parts of grains, so researchers compare ancient and modern wheat.
Traditional use
Farro is eaten cooked in soups, salads and side dishes. Long use as food is not proof that it treats any condition.
Proposed mechanism Preliminary mechanism
Not established. The authors suggest fatty acid changes may be anti-inflammatory.
A proposed mechanism does not show that the effect happens in people.
Contains gluten.
Protein quality (lab analysis)
Very low certaintyIn lab tests, emmer scored better than common and durum wheat for some essential amino acids, but no wheat fully met the reference pattern, and the better scores do not mean less allergy risk.
2 studiesFarro grain as food. Supplements and extracts were not found or read.
Studies, doses and limits
What the trials found
A 2026 analysis of flours and pasta from eight wheat materials found emmer, Kamut and einkorn had more favourable scores for some essential amino acids than common and durum wheat. None met the FAO/WHO reference pattern for all essential amino acids; lysine and histidine were limiting. A 2022 review found ancient wheats contain more protein and gluten than modern bread wheat.
Results
Lab results only; no human effect.
Why this rating
Lab analysis of flours and pasta, not a human study. No human protein-quality trial of farro was found.
Form and dose studied
Farro grain as food. Supplements and extracts were not found or read.
Limits
Industry-sourced samples; emmer samples were few.
Why researchers looked
People wonder whether ancient wheat is a better protein food.
Traditional use
Farro is eaten cooked in soups, salads and side dishes. Long use as food is not proof that it treats any condition.
Proposed mechanism Laboratory
Lab analysis of amino acids; no body effect measured.
A proposed mechanism does not show that the effect happens in people.
The same lab study found IgE-reactive parts stayed in flour and pasta (see Safety tab).

The evidence
The research centre for Farro. 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 the earlier farro page, re-read its PubMed abstracts and the NIDDK, NHS, WHO and MedlinePlus pages. Only abstracts were read for studies. Very little farro-specific research exists, so this page is short on purpose. Items we could not verify are flagged in the research gaps.

Gluten is present in all wheat grains and all can induce coeliac disease in people at risk. Ancient wheats contain more protein and gluten and more coeliac-active parts than bread wheat, so no single wheat type can be recommended as better for coeliac disease. Many people who think they are gluten sensitive are not confirmed when tested; gas from fermentation of fructans in wheat may be the cause. Not applicable (Not applicable) Methods, limits and fundingOutcomes: Gluten and protein content; coeliac disease; symptoms attributed to gluten Limitations: A narrative review, not a trial.

Narrative review |
Review of three unusual causes of food anaphylaxis | Wheat (wheat-dependent exercise-induced anaphylaxis) Grain as food or in food products Not given in the abstract · vs As described in the abstract |
Wheat-dependent exercise-induced anaphylaxis appears when wheat is eaten together with exercise and cofactors such as seafood, alcohol or anti-inflammatory pain medicines. The major allergen is omega-5 gliadin, part of wheat gluten. Symptoms range from hives or swelling to severe anaphylaxis. Not applicable (Not applicable) Methods, limits and fundingOutcomes: Wheat allergy triggered with exercise and other cofactors Limitations: A narrative review about wheat in general, not about farro. Funding and conflicts: Funding is not stated in the abstract. Read: abstract |

What we do not know yet
- No trial of farro (emmer) alone was found for cholesterol, blood sugar, blood pressure, weight or gut health; the cholesterol and heart findings are for whole grains as a group.
- No USDA or peer-reviewed nutrient table was read, so fibre, vitamin and mineral figures are not given.
- Pregnancy, breastfeeding, children, arsenic and heavy metals, FODMAP rating and kidney (potassium, phosphorus) figures were not found or researched for farro.
- How the word farro is regulated on labels was not found.
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
- Farro contains gluten: not safe with celiac disease. NIDDK lists wheat and its varieties, including emmer and spelt, among the sources of gluten. Farro (emmer) is wheat, so it is not safe for people with celiac disease. A 2022 review found gluten is present in all wheat grains and ancient wheats had more gluten and more celiac-active parts than bread wheat, so no single wheat type can be recommended as better for celiac disease. About 1 in 100 people worldwide have celiac disease. NIDDK advises talking with your doctor about celiac testing before starting a gluten-free diet, because cutting out gluten first can make test results inaccurate. Authoritative guidance 13 14 4
- Wheat allergy can be severe. MedlinePlus lists wheat among the foods that most often cause allergy. A rarer form, wheat-dependent exercise-induced anaphylaxis, appears when wheat is eaten together with exercise, alcohol or anti-inflammatory pain medicines; the main allergen is omega-5 gliadin in wheat gluten. A 2026 lab study found IgE-reactive parts remained in ancient wheat flour and pasta after processing. For trouble breathing or swelling of the face or throat, call 911 or your local emergency number. Authoritative guidance 11 10 9
- Cooked grains left out can cause food poisoning. The NHS says spores of some food poisoning bacteria survive cooking in rice and grains. If cooked grains sit at room temperature, the bacteria can make toxins that cause vomiting and diarrhoea, and reheating does not destroy them. Cool cooked grains within 1 hour and refrigerate. The NHS gives these steps for rice and grains in general; farro is not named. Authoritative guidance 12
- Gluten sensitivity without celiac disease. Many people who feel gluten sensitive are not confirmed when tested. A double-blind crossover trial in 37 adults with irritable bowel syndrome found symptoms improved on a low-FODMAP diet and gluten had a specific effect in only 8%. A 2022 review suggests gas from fermented wheat fructans may be the cause in many people. Controlled trial 3 4
Side effects 3
| Effect | How often | Severity and recovery | Evidence |
|---|---|---|---|
| Immune damage to the small intestine in people with celiac disease Applies to all wheat including farro. | About 1% of people worldwide have celiac disease (NIDDK). | can be serious Managed by avoiding gluten, per NIDDK | Authoritative guidance 14 13 |
| Allergic reactions to wheat, from hives to anaphylaxis Wheat in general; farro was not studied alone. | No frequency for farro was found. | can be severe (anaphylaxis) Not stated | Authoritative guidance 11 10 |
| Gas, bloating or stomach discomfort in some people, possibly from wheat fructans A suggested explanation, not shown for farro. | No frequency found. | mild Not studied | Narrative review 4 |
Liver
No liver injury from eating farro was found in the sources read. A liver-safety source (such as LiverTox) was not searched for food.
Monitoring. No agency advice found.
This is a safety connection. It is not evidence that Farro supports liver health.
Medicines and supplements 2
| With | Why it matters | Importance | Evidence | What to do |
|---|---|---|---|---|
| Medicines taken with exercise and wheat (wheat-dependent exercise-induced anaphylaxis) prescription | In people with this rare wheat allergy, anti-inflammatory pain medicines, alcohol or exercise can trigger a reaction when wheat is eaten. | Only for people who have this allergy. | Narrative review Low certainty 10 | If you have had a reaction after wheat plus exercise, ask an allergist. |
| Medicines for diabetes or high cholesterol prescription | Whole-grain diets as a group lowered LDL a little; a big change in diet could in theory add to a medicine's effect. | No source read ties farro to a specific medicine interaction. A general caution, not a documented interaction. | Theoretical Not enough evidence 6 | Ask your clinician or pharmacist before big diet changes if you take such medicine. |
Who should check first 2
| Situation | Advice | Evidence |
|---|---|---|
| Celiac disease or a diagnosed gluten-related condition | Avoid farro and other wheat unless your care team says otherwise. Get tested before starting a gluten-free diet. | Authoritative guidance 13 4 |
| Wheat allergy | Avoid farro and other wheat. Ask an allergist. Call emergency services for trouble breathing or swelling of the face or throat. | Authoritative guidance 11 |
Overdose, product quality and regulators
Summary. No toxicity from cooked farro as ordinary food was found in the sources read.
Animal. Not reviewed.
Overdose response. Not found.
Genotoxicity. Not researched.
Toxic or hazardous parts. Not found.
WHO says deoxynivalenol and zearalenone, made by Fusarium moulds, are often associated with wheat. Farro-specific testing was not found.
Mould toxins in wheat. WHO advises inspecting whole grains and discarding grain that looks mouldy, discoloured or shrivelled; damaged grain is more prone to contamination. 15
Labels: wheat species. A 2021 lab method was built to check whether a product contains einkorn, emmer or spelt versus common or durum wheat, to guard against mislabelling. We did not read a source that sets the rules for the word "farro", so check the pack. 7
Phytate and iron. Whole grains contain phytate. A 2026 review of 8 human studies on bread was inconclusive about the real-life effect of phytate on iron. It did not study farro. 8

Frequently asked questions
Is farro gluten-free?
Is farro safe with celiac disease?
Does ancient wheat have less gluten than modern wheat?
No. A 2022 review found ancient wheats contained more protein and gluten than bread wheat, not less.
Is farro healthier than regular wheat?
Not shown. Animal and lab studies look promising, but a review says there are too few human trials to conclude that ancient wheats are better than modern wheat.
Does farro lower cholesterol?
Not tested on its own. Pooled trials of whole-grain diets found a small drop in LDL cholesterol of about 0.09 mmol/L, with oats working best.
Is farro good for the heart?
Studies that follow people over time link more whole grains to less heart disease, but they are observational and about whole grains in general, not farro.
Can I be allergic to farro?
Yes, if you are allergic to wheat. MedlinePlus lists wheat among the foods that most often cause allergy. For trouble breathing or swelling of the face or throat, call 911 or your local emergency number.
Is farro the same as spelt or einkorn?
No, but labels can overlap. Emmer, einkorn and spelt are all hulled ancient wheats. We did not read a source that sets the rules for the word farro, so check the pack.
Does farro have more protein than other wheat?
Do whole grains block iron absorption?
Whole grains contain phytate, which can reduce iron absorption in a meal. A 2026 review of human bread studies was inconclusive about the real-life effect. Farro was not studied.
How should I store cooked farro?
The NHS says spores of some bacteria survive cooking and make toxins if cooked grains sit at room temperature; reheating does not remove them. Cool within 1 hour and refrigerate. This is general advice for rice and grains.
