There is no single official list of “the 7 ancient grains.” The term comes from marketing and food writing, not from any scientific or agricultural authority. Different sources group different grains into their list of seven, but the most commonly featured ancient grains are amaranth, barley, farro (emmer wheat), millet, quinoa, sorghum, and teff, with spelt, buckwheat, einkorn, and freekeh frequently swapped in. What makes a grain “ancient” is that it has remained largely unchanged through selective breeding over the last several hundred years, unlike modern wheat, which has been extensively modified.
What Makes a Grain “Ancient”
The Whole Grains Council, the closest thing to an authority on the subject, defines ancient grains loosely as grains that are largely unchanged over the last several hundred years. By that definition, modern wheat doesn’t qualify because it has been constantly bred and altered. But older wheat relatives like einkorn, emmer, farro, and spelt do count. So do grains that Western diets largely ignored until recently, like sorghum, teff, millet, quinoa, and amaranth. Heirloom varieties of common grains, such as black barley, red and black rice, and blue corn, sometimes make the list too.
The grains most frequently grouped together in popular “7 ancient grains” lists span different botanical families and different continents. Some are true cereal grains (barley, millet, sorghum, teff, farro, spelt). Others, like quinoa, amaranth, and buckwheat, are technically pseudocereals: seeds from non-grass plants that are cooked and eaten like grains.
The Most Commonly Listed Ancient Grains
Amaranth
Amaranth is a tiny seed originally cultivated by the Aztecs in Central America. It’s naturally gluten-free and cooks quickly, needing about 15 minutes in a 1:3 ratio of grain to liquid. The cooked texture is porridge-like rather than fluffy, which makes it a better fit for cookies, pasta, polenta-style dishes, and as a thickener for soups than for pilafs. It’s high in protein, iron, and magnesium.
Barley
Barley was one of the earliest grains domesticated by humans, appearing in the Fertile Crescent (modern-day Iraq, Iran, Syria, and Turkey) around 10,000 to 12,000 years ago alongside einkorn wheat. It contains gluten, so it’s not safe for people with celiac disease. Hulled barley retains the most nutrients but takes about 1 hour and 45 minutes to cook. Pearl barley, which has the outer bran layer polished off, cooks in 45 to 55 minutes and has a mild, slightly chewy texture that works well in soups and stews.
Farro
“Farro” is actually an umbrella term for three ancient wheat species: einkorn, emmer, and spelt. In the United States, farro most often refers to emmer. All three contain gluten. Farro has a nutty flavor and a pleasantly chewy bite that holds up well in grain salads, risotto-style dishes, and soups. Emmer was one of the first wheat species domesticated, going back 10,000 to 12,000 years.
Millet
Millet is a group of small-seeded grains that have been staple foods across Africa and Asia for thousands of years. It’s naturally gluten-free. Millet cooks in about 25 to 30 minutes using a 1:3 grain-to-liquid ratio, and benefits from 10 minutes of resting time off the heat afterward. With less water it turns out light and fluffy, almost like couscous. With more water it becomes creamy, making a good porridge. Early research suggests millet may offer modest benefits for blood sugar management in people with type 2 diabetes, though the evidence isn’t strong enough yet for formal dietary recommendations.
Quinoa
Quinoa originated in the Andes region of South America and is one of the few plant foods that qualifies as a complete protein, meaning it contains all nine essential amino acids your body can’t produce on its own. That makes it especially valuable for vegetarians and vegans. It’s gluten-free, cooks in just 15 minutes with a 1:2 grain-to-liquid ratio, and has a light, slightly nutty flavor. Rinse it before cooking to remove the natural coating (saponins) that can taste bitter.
Sorghum
Sorghum is the fifth most produced cereal crop in the world, widely grown across Africa, India, and the southern United States. It’s gluten-free and has a mild, slightly sweet flavor. The whole grain can be cooked and used like rice, popped like popcorn, or ground into flour for baking. Sorghum flour works particularly well as a wheat substitute in recipes like pancakes and waffles.
Teff
Teff is a tiny grain native to Ethiopia, where it’s the primary ingredient in injera, the spongy flatbread served with most meals. It’s gluten-free and remarkably mineral-dense. A study comparing teff to wheat and maize found significantly higher concentrations of calcium (1,210 mg/kg), iron (159 mg/kg), and magnesium (1,400 mg/kg) in teff. That iron content is particularly notable for a grain. Teff flour works well in baked goods like cookies and quick breads, and the whole grain cooks into a porridge-like consistency.
Other Grains That Frequently Appear
Spelt, buckwheat, einkorn, and freekeh are commonly included in various “ancient grain” lists. Spelt is a wheat relative that dates to around 7,000 BC and is the most widely available ancient wheat in the United States. It contains gluten. Buckwheat, despite the name, is not related to wheat at all. It’s a gluten-free pseudocereal with a distinctive earthy flavor, and its groats cook in about 15 minutes.
Which Ancient Grains Are Gluten-Free
This is one of the most important practical distinctions. Many people assume “ancient” means “gluten-free,” but that’s not the case. According to Beyond Celiac, the gluten-free ancient grains include amaranth, millet, sorghum, teff, and fonio. Grains that contain gluten include barley, farro, emmer, einkorn, spelt, freekeh, and kamut. A 2013 study confirmed that ancient wheat varieties still trigger the same autoimmune response in people with celiac disease as modern wheat. Being older doesn’t make a wheat grain safer for gluten-sensitive individuals.
Nutritional Advantages Over Modern Grains
Ancient grains tend to be higher in fiber, protein, and micronutrients than refined modern wheat, though the gap narrows considerably when you compare them to whole wheat. The real nutritional advantage is variety. Different ancient grains bring different strengths: quinoa provides complete protein, teff delivers unusually high iron and calcium, amaranth is rich in magnesium, and barley offers a particularly high fiber content including beta-glucan, a type of soluble fiber linked to lower cholesterol.
For blood sugar management, ancient grains generally have a lower glycemic index than refined white flour products. Current dietary guidelines for type 2 diabetes recommend choosing carbohydrates with a lower glycemic index, and whole ancient grains fit that pattern. That said, a large meta-analysis found that while results were generally positive for grains like oats, brown rice, and millets, the studies varied too much in design to draw firm conclusions.
How to Cook Ancient Grains
Most ancient grains follow a simple formula: combine with water or broth, bring to a boil, reduce heat, and simmer until tender. The main variables are liquid ratio and time.
- Quick-cooking (15 minutes): Amaranth (1:3 ratio), quinoa (1:2), buckwheat groats (1:2)
- Medium (25 to 55 minutes): Millet (1:3, plus 10 minutes resting), pearl barley (1:3)
- Long-cooking (over 1 hour): Hulled barley (1:4, about 1 hour 45 minutes)
Farro and spelt cooking times vary depending on whether they’re whole, semi-pearled, or pearled. Semi-pearled farro, the most common variety in grocery stores, typically takes about 20 to 30 minutes. All ratios above are per one cup of dry grain. Most ancient grains roughly triple in volume when cooked, so one cup dry yields about three cups cooked.
For the best texture in salads and grain bowls, cook grains until they’re tender but still have a slight chew, then spread them on a sheet pan to cool. For soups and porridges, cook them longer with more liquid until they soften and release starch.
