Quinoa has an exceptional balance of protein, fat, and carbohydrates (mainly starch). Among the amino acids present in its proteins are lysine (important for brain development) and arginine and histidine, essential for human development during childhood. It is also rich in methionine and cystine, in minerals such as iron, calcium and phosphorus, and in vitamins, while it is low in fat, thus complementing other cereals and / or legumes such as green beans.
