Nutritionally quinoa might be considered a super grain. Although it is not really a grain - but the seed of a leafy plant that is distantly related to spinach. Quinoa has excellent reserves of protein - so the protein is more complete (a trait it shares with other ''non-true" grains such as buckwheat and amaranth). The World Health Organization has rated the quality of protein in quinoa at least equivalent to that in milk. Quinoa offers more iron than other grains and contains high levels of potassium and riboflavin - as well as other B vitamins: B6 - niacin - and thiamin. It is also a good source of magnesium - zinc - copper - and manganese - and has some folate (folic acid).
