The short answer

Quinoa isn’t a millet. Millets are grasses (family Poaceae), so they’re true cereals, while quinoa is the seed of a broadleaf plant in the Amaranthaceae family, which is why it’s called a pseudocereal. In a millet vs quinoa comparison, cooked calories are almost equal, but quinoa has more protein and fiber and about 3.5 times the lysine.

Is quinoa a millet?

No. “Millet” is a name for the small-seeded grains of several different grasses. USDA’s record for cooked millet lists its scientific name simply as Poaceae, the grass family that wheat, rice and corn also belong to. That makes millets true cereals.

Quinoa comes from a completely different branch of the plant world. Washington State University Extension places it in the Amaranthaceae family, “along with garden favorites spinach and beets as well as the weed lambsquarters.” Older books file it under Chenopodiaceae, which is now usually treated as part of Amaranthaceae. Quinoa is cooked and eaten like a grain without being a grass, so it’s called a pseudocereal. So millets and quinoa aren’t the same thing, even though they end up in the same kinds of dishes.

Is quinoa the same as korralu (foxtail millet)?

No. Korralu, the Telugu name for foxtail millet, is Setaria italica, a grass. The FAO notes that foxtail millet is widely grown in India, though it was first domesticated in East Asia. Quinoa is a different plant from a different family. The two can stand in for each other in a pilaf or a bowl, but botanically they aren’t related.

Millet isn’t one grain: the main types

When a recipe or a nutrition label says “millet,” it could mean any of several grasses. These are the main millets listed by the FAO.

Millet Scientific name Other names Suggested origin
Pearl millet Pennisetum glaucum Bajra, cumbu, bulrush millet Tropical West Africa
Finger millet Eleusine coracana Ragi, African millet Uganda or a nearby region
Foxtail millet Setaria italica Italian or German millet East Asia (China)
Proso millet Panicum miliaceum Common millet, broom-corn millet Central and East Asia
Kodo millet Paspalum scrobiculatum Kodo India
Little millet Panicum sumatrense Little millet Southeast Asia
Barnyard millet Echinochloa crus-galli Sawa millet Japan

Source: FAO, Sorghum and millets in human nutrition, Table 1.

USDA’s raw millet record is proso millet, Panicum miliaceum; the cooked record used below doesn’t name a species. Ragi, bajra and other millets will have different numbers.

Millet vs quinoa nutrition per 100g

Cooked, the two have almost the same calories. Quinoa comes out ahead on protein, fiber and most minerals. Millet has more niacin.

Per 100 g, cooked Millet Quinoa
Calories 119 kcal 120 kcal
Protein 3.5 g 4.4 g
Carbohydrates 23.7 g 21.3 g
Fiber 1.3 g 2.8 g
Fat 1.0 g 1.9 g
Iron 0.63 mg 1.49 mg
Magnesium 44 mg 64 mg
Potassium 62 mg 172 mg
Manganese 0.27 mg 0.63 mg
Folate 19 µg 42 µg
Niacin (B3) 1.33 mg 0.41 mg

Source: USDA FDC 168871 (millet, cooked) and USDA FDC 168917 (quinoa, cooked).

Per cooked cup, the gap holds: about 8.1 g of protein and 5.2 g of fiber for quinoa against about 6.1 g and 2.3 g for millet. For calories by cup size, vitamins and the uncooked values, see quinoa’s full nutrition facts.

Protein quality: the lysine gap

The biggest difference isn’t how much protein each grain has but what that protein is made of. Lysine is an essential amino acid, meaning your body can’t make it. According to the FAO, it’s the most limiting amino acid in millet protein, and in foxtail millet it’s followed by tryptophan and the sulfur amino acids. Quinoa doesn’t have that weak spot. Using the USDA records, we calculated about 54 mg of lysine per gram of protein in quinoa and about 19 mg in millet. Per 100 g cooked, that’s 0.24 g against 0.07 g.

Foxtail millet vs quinoa

USDA’s standard reference data has no entry for foxtail millet, so we used the FAO’s composition table for the raw grain and set it beside USDA’s uncooked quinoa.

Per 100 g, raw Foxtail millet Quinoa, uncooked
Energy 351 kcal 368 kcal
Protein 11.2 g 14.1 g
Fat 4.0 g 6.1 g
Carbohydrates 63.2 g 64.2 g
Calcium 31 mg 47 mg
Iron 2.8 mg 4.6 mg
Thiamin (B1) 0.59 mg 0.36 mg
Niacin (B3) 3.2 mg 1.5 mg

Sources: FAO, Sorghum and millets in human nutrition, Table 17 (12% moisture; data from 1980–1984) and USDA FDC 168874.

Treat this as a rough guide. The two columns come from different databases, decades apart. The FAO reports crude fiber, which is measured differently from the dietary fiber on US labels, so we left fiber out. The overall picture still matches the cooked comparison: quinoa is ahead on protein, fat and iron, and foxtail millet on thiamin and niacin.

Glycemic index: millet vs quinoa

Cooked quinoa has a GI of about 53, according to the Glycemic Index Foundation at the University of Sydney. That’s low, since 55 or under counts as low. “Millet” has no single GI because the species and dishes vary so much. In the 2008 international GI tables, millet porridge averages 67 ± 5, which is medium.

So which is better for diabetes, millet or quinoa? We found no study that compared the two head to head. On the available numbers, quinoa has the lower GI, but portion size and the rest of the meal matter at least as much. If you manage diabetes, plan carbohydrate portions with your doctor or dietitian. For another everyday comparison, see whether quinoa or oats suits your breakfast better.

Frequently asked questions

What is a major drawback of millet?

Its protein is low in lysine, so on its own it’s a weaker protein source than quinoa or legumes. The FAO also describes compounds in pearl millet that can affect the thyroid: rats fed pearl millet diets developed thyroid changes, and goiter was more common in rural Sudan, where pearl millet was the only staple, than in towns where other grains were eaten. The FAO adds that more evidence is needed to understand how these compounds act.

Are millet and quinoa gluten-free?

Yes, both are naturally gluten-free. University of Arizona Campus Health lists millet and quinoa among the whole grains allowed on a gluten-free diet. Gluten-free grains can pick up traces of wheat in fields, mills or shared bulk bins, though. If you have celiac disease, buy packs labeled certified gluten-free and avoid scooping from shared bins.

Which millet is closest to quinoa?

None matches quinoa’s lysine. On raw protein, proso millet (12.5 g per 100 g in the FAO table, 11.0 g in USDA’s), pearl millet (11.8 g) and foxtail millet (11.2 g) come nearest to quinoa’s 14.1 g. In the kitchen, they’re closer. The FAO notes that hulled millet is sometimes boiled and served like rice, which is how you’d use quinoa in bowls, pilafs and salads.

Is millet the healthiest grain?

No single grain holds that title. Millet is a gluten-free whole grain with more niacin than quinoa. Per 100 g cooked, though, it has less protein, lysine, fiber, iron, magnesium and potassium, as the tables above show. The better choice depends on what the grain has to do in your meal.

Can I use millet instead of quinoa?

Yes, in most savory dishes. Oregon State University Extension cooks both in 2 cups of water per cup of grain: millet simmers for 20 minutes, quinoa for 12 plus 5 to 10 minutes’ rest, and each makes about 3 cups. Expect a little less protein and fiber per serving. The same swap logic applies to wheat-based options, as in our comparison of quinoa and bulgur wheat, and there are other good swaps for quinoa too.
