Farro vs quinoa: small lipid drops for quinoa, no human trials for farro

A meta-analysis of 5 randomized trials in 206 adults found quinoa lowered LDL cholesterol by 3.08 mg/dL (95% CI 1.03 to 5.13) and triglycerides by 7.20 mg/dL, from few and small studies. The same analysis reported a 2.8 lb (1.26 kg) drop in body weight, and that result has not held up. A later meta-analysis of 7 trials in 258 adults found no effect on weight (-1.2 lb (95% CI -6.7 to 4.3; metric: -0.54 kg, -3.05 to 1.97)) or BMI against placebo. Both rest on a handful of small trials, so whether quinoa moves weight is still open. For farro there is nothing to report on health. We found no human trial of farro in our sources, and no study comparing the two grains. The two are not interchangeable for people with celiac disease or wheat allergy. Farro is emmer, a wheat, and US and EU allergen rules count it as wheat and as a gluten cereal. On paper they look alike. Per 100 g dry, pearled farro has 12.6 g protein and 7.31 g fiber, and quinoa flour 11.9 g and 6.30 g, from 8 USDA samples each, although that sets a whole grain against a flour.

How much is actually in it

• Per 100 g dry, pearled farro and quinoa flour carry similar protein (about 12 g) and fiber (6 to 7 g), while quinoa flour has about twice the fat and more iron. — USDA Foundation Foods analyzed samples (n = 8 samples per food) Evidence E source
  Farro vs quinoa flour per 3.5 oz (100 g): protein 12.6 vs 11.9 g, fiber 7.31 vs 6.30 g, fat 3.10 vs 6.60 g, iron 3.20 vs 4.53 mg, zinc 3.97 vs 2.77 mg
• The UK table lists raw quinoa at 7.8 mg iron per 3.5 oz (100 g), above every US quinoa flour sample (3.55 to 6.6 mg), showing how much iron figures can differ. — CoFID code 14-843 (Quinoa, raw) (n = -) Evidence E source
  Energy 309 calories, protein 13.8 g, fiber 7.0 g, iron 7.80 mg, magnesium 210 mg, zinc 3.3 mg per 3.5 oz (100 g)

What a real portion looks like

• In the US dietary survey one cup of cooked quinoa weighs 6 oz (170 g), and farro has no survey portion at all. — FNDDS food code 56204005 (Quinoa, no added fat) (n = -) Evidence E source
  1 cup cooked = 170 g

What your body absorbs

• Laboratory digestion data suggest quinoa starch has a high slowly digestible fraction. — In vitro digestion of starches from underutilised seeds (n = -) Evidence D source
  High SDS fraction for quinoa starch, no human data

What cooking and storage change

• A review of quinoa processing concludes that how quinoa is processed changes its nutrient profile and health effects, though it gives no single number for the size of the change. — Review of quinoa processing technologies (n = -) Evidence D source
  Direction only, no effect size

What it does to your health

• A meta-analysis of 5 RCTs (206 adults) found quinoa lowered body weight by 2.8 lb (1.26 kg), triglycerides by 7.20 mg/dL and LDL by 3.08 mg/dL. — 5 RCTs, 206 adults (n = 206) Evidence A source
  Weight -2.8 lb (95% CI -5.2 to -0.4; metric: -1.26 kg, -2.35 to -0.18), TG -7.20 mg/dL (-9.52 to -4.87), LDL -3.08 mg/dL (-5.13 to -1.03)
• In a one-year RCT of 207 people with impaired glucose tolerance, 100 g quinoa a day improved post-meal glucose and insulin resistance more than the same amount of mixed whole grains. — 207 adults with impaired glucose tolerance, 1 year, 100 g/day replacing about half the staple food (n = 207) Evidence B source
  Better 2hPG, fasting insulin, HOMA-IR, time in range and diabetes development vs multigrain and control (P < 0.05)
• In a 4-week crossover RCT of 37 overweight men, bread with 20 g quinoa flour daily did not change LDL or blood glucose more than refined wheat bread. — 37 healthy overweight men aged 35-70, 4-week crossover with 4-week washout (n = 37) Evidence B source
  Glucose and LDL lower than baseline in both groups, no difference between quinoa and wheat

Safety, limits and interactions

• In 19 treated celiac patients, 50 g quinoa daily for 6 weeks was well tolerated and did not worsen gut histology. — 19 adults with treated celiac disease on a gluten-free diet, 6 weeks (n = 19) Evidence C source
  Villus height to crypt depth 2.8:1 to 3:1, total cholesterol 178 to 166 mg/dL (4.6 to 4.3 mmol/L)
• FDA counts every species of the genus Triticum as wheat, a major food allergen, and names emmer, einkorn and spelt among them. — US food allergen labeling, FD&C Act as amended by FALCPA Evidence E source
  Wheat = any species in the genus Triticum; emmer (Triticum turgidum subsp. dicoccon) and einkorn (Triticum monococcum) listed
• EU food law lists cereals containing gluten, wheat such as spelt and khorasan included, among the substances causing allergies or intolerances that labels must declare. — foods sold in the EU, Regulation (EU) No 1169/2011 Annex II Evidence E source
  Cereals containing gluten (wheat, rye, barley, oats, their hybrids and products) must be emphasized as allergens
• Laboratory tests on gut T-cells from celiac children found that gluten proteins from most of 9 farro wheat (emmer) landraces triggered an immune response, 4 strongly and 2 moderately. — mucosal T-cells from 4 celiac patients exposed to digested prolamins from 9 landraces of farro wheat (Triticum turgidum ssp. dicoccum) (n = 4 patients, 9 landraces) Evidence D source
  4 landraces very active, 2 intermediate, 3 negligible T-cell proliferation and IFN-gamma release
• In an open study, 8 celiac patients in remission were enrolled to eat 3.5 oz (100 g) a day of einkorn wheat biscuits for 60 days. Of 5 who finished, 4 developed severe gut lesions and 3 turned antibody positive, and 2 others dropped out with symptoms. — celiac patients in remission on a gluten-free diet, 100 g/day Triticum monococcum (einkorn) water biscuits for 60 days (n = 8) Evidence C source
  Marsh III lesions in 4 of 5 completers at day 60, dermatitis herpetiformis relapse in 1, antibody conversion in 3; 2 dropouts with symptom recurrence

What people believe that the data does not support

• The EU did not authorize a claim that quinoa stimulates the hair bulb and favors hair growth. — EU health claims register (n = -) Evidence E source
  Non-authorized

Who this works differently for

• In NHANES 2013-2018, only 1.07% of US adults ate quinoa, against 0.36% for barley and 0.04% for buckwheat. — US adults aged 20+, NHANES 2013-2018 (n = 14806) Evidence C source
  Quinoa consumption prevalence 1.07%, barley 0.36%, buckwheat 0.04%

What is still unknown

• A later meta-analysis of 7 trials (258 adults, 15 to 50 g a day) found no effect of quinoa on body weight or BMI, which contradicts the earlier weight result. — 7 trials, 258 adults aged 31-64, 28-180 days (n = 258) Evidence A source
  BMI MD -0.25 (95% CI -0.98 to 0.47), body weight MD -1.2 lb (-6.7 to 4.3; metric: -0.54 kg, -3.05 to 1.97)

The bottom line

Quinoa flour has more fat (6.60 against 3.10 g per 3.5 oz (100 g)) and more iron (4.53 against 3.20 mg), and farro has more zinc (3.97 against 2.77 mg). Iron is the shakiest figure. US quinoa flour samples ranged from 3.55 to 6.6 mg per 3.5 oz (100 g), and the UK table lists raw quinoa grain at 7.8 mg, with grain against flour and different varieties and methods behind the gap. One cup of cooked quinoa weighs 6 oz (170 g) in the US dietary survey. Farro has no survey portion at all, and only 1.07 percent of US adults ate quinoa on a given day in 2013 to 2018. The strongest single trial is in people who already had trouble with blood sugar. In a one-year randomized trial of 207 adults with impaired glucose tolerance, eating quinoa in place of about half their staple food gave better post-meal glucose, lower insulin resistance and fewer cases of diabetes than mixed whole grains or the control diet. The abstract reports P values only, with no sizes, and people with normal glucose were not studied. In 37 healthy overweight men over 4 weeks, bread made with quinoa flour lowered glucose and LDL from baseline, and so did plain wheat bread, with no difference between the two. Laboratory digestion data suggest isolated quinoa starch has a large slowly digested fraction, with no human data behind it. A review of processing says the way quinoa is processed changes its nutrients, without giving any number. The EU refused a claim that quinoa stimulates the hair bulb and helps hair grow, which means the evidence did not meet the bar when assessed. Who should be careful. In 19 adults with treated celiac disease, adding 1.8 oz (50 g) of quinoa a day to a gluten-free diet for 6 weeks was well tolerated and did not make the condition worse, in a study with no control group. That result covers quinoa only and does not carry over to farro. FDA counts every species of the genus Triticum as wheat, a major food allergen, and names emmer among them. EU law lists wheat among the gluten cereals that labels must declare as allergens. In laboratory tests on gut T-cells from celiac children, gluten proteins from most of 9 farro landraces triggered an immune response, 4 strongly and 2 moderately, and 3 barely did. No clinical study has tested farro in people with celiac disease. The nearest is an open study of einkorn, a related ancient wheat. Of 5 celiac patients in remission who finished 60 days of 3.5 oz (100 g) of einkorn biscuits a day, 4 developed severe gut lesions and 3 turned antibody positive. Two others dropped out with returning symptoms. We have no studies on pregnancy or drug interactions for either grain, and none on quinoa allergy.
