Quinoa is a seed, which is prepared and eaten like a grain. It has been consumed for thousands of years in South America and is now considered to be a ‘superfood’. It is an excellent source of protein as it has an essential amino acid profile reported to be equivalent to that of casein and dried whole milk. Additionally, lysine, one of the limiting amino acids in cereal grains, is found at levels twice as high as those in wheat or maize. It is non-GMO and gluten-free, and has high digestibility.
