Quinoa is a shrub whose seeds are eaten and come in many colors: white, red, black and blue. Quinoa was of great nutritional importance to ancient Andean civilizations. It was the second main food after potatoes and was followed by corn. Today it is highly regarded for its nutritional value and the United Nations has classified it as a superfood for its high protein content (13%). Unlike rice or wheat, which are low in lysine, quinoa contains a balanced content of essential amino acids. This means that we need less quinoa protein than wheat protein for our needs. Although it is actually a seed, quinoa is considered a complete grain and a good source of fiber. Quinoa also contains omega 3 fats, which do not harm the heart. It is also a good source of phosphorus and has a lot of magnesium and iron.
