No, Amaranth and Quinoa are Distinct Pseudocereals
Despite being grouped as "ancient grains," amaranth ($Amaranthus$ spp.) and quinoa ($Chenopodium quinoa$) are botanically distinct species. While both hail from the Amaranthaceae family, they diverge significantly in their physical traits, nutritional composition, and culinary applications. The misconception that they are the same likely stems from their similar appearance as small, nutritious seeds and their shared history as staples in ancient American diets. However, a closer look reveals that these two powerhouse foods are unique.
The Amaranth Plant: An Aztec Staple
Belonging to the sub-family Amaranthoideae, amaranth has a long history with pre-Columbian civilizations, particularly the Aztecs, who used it in ceremonial rituals. The plant is multi-purpose, with some varieties grown for their edible greens and others for their seeds. The seeds themselves are very small, about the size of sesame seeds, and are typically pale-golden. When cooked, amaranth softens into a sticky, porridge-like consistency, and has a more potent, nutty, and earthy flavor compared to quinoa.
The Quinoa Plant: A Sacred Inca Crop
Quinoa, from the sub-family Chenopodiaceae, was a sacred crop for the Incas, who referred to it as "chisaya mama" or "mother of all grains". Quinoa seeds are larger than amaranth and come in a wider variety of colors, including white, red, and black. Unlike amaranth, cooked quinoa retains its individual, fluffy grains and has a milder, nuttier flavor profile. The outer coating contains saponins, a bitter-tasting compound that must be rinsed off before cooking.
Amaranth vs. Quinoa: A Side-by-Side Comparison
| Feature | Amaranth ($Amaranthus$ spp.) | Quinoa ($Chenopodium quinoa$) |
|---|---|---|
| Botanical Classification | Amaranthaceae (Sub-family Amaranthoideae) | Amaranthaceae (Sub-family Chenopodiaceae) |
| Seed Appearance | Very small, round, pale-golden | Larger, disc-shaped, wide variety of colors (white, red, black) |
| Cooked Texture | Porridge-like, sticky | Fluffy, separate grains, slightly chewy |
| Flavor Profile | Strong, earthy, and nutty | Mild and nutty, takes on other flavors |
| Preparation Note | No rinsing typically required | Must be rinsed to remove bitter saponins |
| Protein Content | Slightly more protein per serving | All nine essential amino acids |
| Nutritional Highlights | Higher in calcium and iron | Higher in B vitamins, magnesium, and potassium |
| Glycemic Index | High (97 for cooked grain) | Low (53) |
Nutritional Showdown: Which Pseudocereal is Better?
The choice between amaranth and quinoa depends on your specific nutritional goals and culinary preferences, as both are excellent sources of nutrients. Both are gluten-free and considered complete proteins, meaning they contain all nine essential amino acids.
Protein and Amino Acids
While both offer high-quality protein, amaranth is slightly higher in protein content per serving compared to quinoa. Amaranth's protein is especially rich in lysine, an amino acid often lacking in common cereals. Quinoa is also well-regarded for its balanced amino acid profile, making both seeds valuable for plant-based diets.
Vitamins and Minerals
The mineral content varies between the two. Amaranth is notably higher in calcium and iron, two crucial minerals that many people lack. A single cup of cooked amaranth can offer nearly double the iron of a cup of cooked quinoa. On the other hand, quinoa is richer in B vitamins (like B1, B2, and folate), potassium, and zinc. Both are good sources of magnesium.
Dietary Fiber
Both are excellent sources of dietary fiber, which is crucial for digestive health. The fiber content aids in regulating blood sugar and promoting a feeling of fullness. Quinoa's relatively low glycemic index of 53 makes it particularly beneficial for blood sugar control compared to amaranth's high glycemic index of 97.
Culinary Uses and How to Cook Them
Knowing the distinct characteristics of amaranth and quinoa is key to unlocking their culinary potential. While both can be used in similar dishes, their different textures and flavors mean they are not interchangeable without affecting the outcome.
Cooking with Amaranth
Amaranth requires a slightly different approach than quinoa. Use a 1:3 ratio of amaranth to water and simmer for about 20-25 minutes, or until tender. The result is a creamy, porridge-like texture that makes it perfect for breakfast cereals, thickening soups, or binding ingredients in vegetarian patties. Popping amaranth is another popular method; it cooks like popcorn and can be used as a crunchy garnish or cereal.
Cooking with Quinoa
Quinoa is famously quick and easy to cook. It's essential to rinse it thoroughly first to remove the bitter saponins. Use a 1:2 ratio of quinoa to water or broth, bring to a boil, then reduce heat and simmer for 15-20 minutes. The grains will become translucent and the germ will separate, forming a small "tail". This produces fluffy, distinct grains that are ideal for salads, side dishes, or as a bed for curries and stews. Red and black quinoa varieties hold their shape better than white quinoa, making them a good choice for salads.
Conclusion: Amaranth and Quinoa Are Distinct and Delicious
In conclusion, the answer to "Is amaranth called quinoa?" is a clear no. While they share the classification of pseudocereal and offer comparable nutritional excellence, they are fundamentally different species with unique properties. Quinoa provides a fluffier texture and milder flavor, making it a versatile rice substitute, whereas amaranth cooks into a creamy porridge with a more assertive taste, ideal for soups and breakfast dishes. Ultimately, incorporating both into your diet can enrich your nutrition with a wide array of vitamins, minerals, and high-quality protein. For those seeking to expand their gluten-free options, understanding the unique characteristics of each seed is the first step toward more creative and nutritious cooking.

FAQs
Q: What is the main difference between amaranth and quinoa? A: The main difference lies in their botanical identity and cooked characteristics. Amaranth is very small and cooks into a sticky porridge, while quinoa is a larger seed that cooks up fluffy and separate.
Q: Do amaranth and quinoa taste the same? A: No, their flavors are distinct. Amaranth has a more robust, earthy, and nutty flavor, whereas quinoa has a milder, less intense taste.
Q: Which one is more nutritious, amaranth or quinoa? A: Both are highly nutritious, but they offer different benefits. Amaranth has more calcium and iron, while quinoa has more B vitamins and a lower glycemic index. The "better" one depends on individual dietary needs.
Q: Are both amaranth and quinoa gluten-free? A: Yes, both amaranth and quinoa are naturally gluten-free and safe for those with celiac disease or gluten sensitivity.
Q: Why do you have to rinse quinoa but not amaranth? A: Quinoa seeds have a natural, bitter coating called saponin, which must be rinsed off before cooking to improve the flavor. Amaranth does not have this coating.
Q: Can you substitute amaranth for quinoa in recipes? A: You can, but you must be aware of the textural differences. The sticky texture of cooked amaranth is not ideal for salads where fluffy grains are desired, but it works well in porridge or as a thickener.
Q: Why are both amaranth and quinoa called pseudocereals? A: They are called pseudocereals because they are seeds used culinarily like cereal grains, but they do not come from the grass family ($Poaceae$) like true cereals such as wheat and rice.
Q: Which pseudocereal is easier to cook? A: Many people find quinoa easier to cook because it consistently produces separate, fluffy grains, and has a shorter cooking time than amaranth. However, both are relatively quick and simple to prepare.
Q: Can you pop amaranth like popcorn? A: Yes, amaranth can be popped in a hot, dry skillet, similar to popcorn. This creates a light, crunchy garnish or cereal. Quinoa does not pop in the same way.
