Understanding Amaranth: Not a True Grain
Despite its common label as an ancient grain, amaranth is not a true cereal grain. True grains, such as wheat, oats, and rice, come from plants in the grass family (Poaceae). Amaranth, along with other popular health foods like quinoa and buckwheat, is a pseudocereal. Pseudocereals are seeds that are used and prepared culinarily in the same way as cereal grains but come from non-grass plants. Amaranth belongs to the Amaranthaceae family, which also includes plants like beets, chard, and spinach.
The Historical Roots of Amaranth
Amaranth has a long and rich history dating back millennia, primarily in Central and South America. It was a staple food for the Aztec, Inca, and Maya civilizations, who valued it not only for its sustenance but also for its ceremonial and religious significance. The Aztecs, for instance, used amaranth seeds to create effigies of their gods. After the Spanish conquest in the 16th century, the cultivation of amaranth was banned in an attempt to suppress indigenous religious practices. Despite this, it was preserved by indigenous farmers and continued to grow as a resilient weed. It wasn't until the American health food movement in the 1970s that amaranth saw a resurgence in popularity.
The Impressive Nutritional Profile of Amaranth
Amaranth's rising popularity is largely due to its remarkable nutritional benefits. It is a dense source of vital nutrients that surpass many traditional cereal grains.
Key nutritional highlights of amaranth include:
- Complete Protein: Unlike many plant-based proteins, amaranth contains all nine essential amino acids, making it a complete protein source. Its protein quality is often compared to animal-based proteins.
- High in Lysine: Amaranth is particularly rich in the amino acid lysine, which is often lacking in other grains like wheat and corn.
- Rich in Minerals: Amaranth is an excellent source of essential minerals. It contains more calcium, magnesium, and iron than many common grains.
- Dietary Fiber: With a high fiber content, amaranth promotes healthy digestion and can aid in weight management by helping you feel full. It contains both soluble and insoluble fiber.
- Antioxidants: The seeds are rich in antioxidants like phenolic acids, which help protect the body from free radicals and reduce inflammation.
- Squalene: Amaranth oil, extracted from the seeds, contains a high concentration of squalene, a natural antioxidant also used in cosmetics for skin health.
Amaranth vs. Cereal Grains: A Nutritional Comparison
| Feature | Amaranth (Cooked) | Wheat (Cooked) | Rice (White, Cooked) |
|---|---|---|---|
| Classification | Pseudocereal (Seed) | True Cereal Grain (Grass) | True Cereal Grain (Grass) |
| Gluten-Free? | Yes | No | Yes |
| Complete Protein? | Yes (Contains all 9 essential amino acids) | No (Low in lysine) | No (Low in lysine) |
| Protein Content | Higher than most true grains | Lower than amaranth | Lower than amaranth |
| Calcium Content | Significantly higher | Much lower | Low |
| Magnesium Content | Higher than many grains | Lower than amaranth | Lower than amaranth |
| Fat Content | Up to 3 times higher than cereals | Lower than amaranth | Lower than amaranth |
Culinary Uses and Preparation Methods
Amaranth is a highly versatile food that can be enjoyed in many ways. Unlike some grains that retain their shape perfectly after cooking, amaranth tends to thicken into a porridge-like consistency, making it an excellent base for various dishes.
To cook amaranth:
- For a Porridge: Combine 1 cup of amaranth with 2½ cups of water or milk. Bring to a boil, then reduce heat and simmer for about 20 minutes, stirring occasionally, until the liquid is absorbed and the mixture is creamy.
- For a Fluffy Side Dish: Use a 1:1.5 ratio of amaranth to water. Boil the water, add the amaranth, cover, and simmer for 18-20 minutes. The grains will be tender with a slightly crunchy exterior.
- Popped Amaranth: Heat a dry skillet over high heat and add a tablespoon of amaranth seeds, covering immediately. Shake the pan constantly for 20 seconds as the seeds pop, then remove from heat. Popped amaranth is a great crunchy topping for salads, yogurt, or as a breakfast cereal.
- Amaranth Flour: The grain can be milled into a flour, ideal for gluten-free baking. Because it lacks gluten, it is best used in recipes that don't require rising, such as pancakes, flatbreads, and cookies. It also works well as a thickener for soups and stews.
Health Benefits and Modern Applications
The nutritional density of amaranth offers several potential health benefits, making it a valuable addition to a modern, health-conscious diet.
Some of the documented benefits include:
- Reduced Inflammation: Studies have shown that amaranth can help reduce inflammation in the body, which is a factor in many chronic diseases.
- Lower Cholesterol: Animal studies have indicated that both amaranth grain and oil can help lower total and "bad" LDL cholesterol levels.
- Weight Management: Its high protein and fiber content can promote feelings of fullness and reduce appetite, which aids in weight loss efforts.
- Gluten-Free Alternative: For those with celiac disease or gluten sensitivity, amaranth is a safe and nutritious substitute for wheat and other gluten-containing grains.
- Rich Source of Squalene: Amaranth seeds are one of the highest plant-based sources of squalene, which is valued for its potential antioxidant, anti-tumor, and cholesterol-lowering properties. Research suggests that amaranth oil can contain more squalene than even olive oil.

Conclusion: A Seed with Ancient Power
Ultimately, the answer to "what type of grain is amaranth?" is that it isn't a grain at all, but rather a nutrient-packed pseudocereal with an incredible history and potent health benefits. Its naturally gluten-free nature, complete protein profile, and rich mineral content make it a superior choice for a diverse and healthy diet. From ancient ceremonial food to a modern 'superfood,' amaranth's resilience and versatility ensure it remains a powerful and nourishing option in kitchens around the world.
