It is a light and quickly absorbed food. Amaranth proteins are of the highest quality, higher than any other types of grains or protein products, and contains two or three times more of one of the most important amino acids, lysine, than other grain cultures. On the other hand, it contains least carbohydrates. A handful of amaranth has more calcium than half of a glass of milk. According to research, if one is following a vegetarian nutrition, amaranth is more valuable than wheat, maize, rice or soybean.
