Amaranth, also known as kiwicha, is a tiny, grain-like seed that packs a big nutritional punch. Higher in protein than many other grains, it is a great gluten-free option that boasts nutrient density, thickening abilities and a mild flavor. Amaranth is a great addition to vegan diets where protein sources are all plant-based. It is also high in iron, magnesium, phosphorus and potassium and contains more than three times the average amount of calcium usually found in grains. Amaranth is also the only grain known to contain vitamin C. It can be served alone as an alternative to rice or quinoa, or added to soups and grain salads.
