Amaranth is highly vitamin-rich and is a good source of vitamin A, vitamin B6, vitamin K, vitamin C, folate and riboflavin. It includes numerous minerals such as calcium, potassium, iron, copper, magnesium, phosphorus and especially manganese. Amaranth contains large amounts of protein, up to 30% more than wheat flour, rice and oats. The protein contained in amaranth is also unusually complete when compared to other plant sources, containing a complete set of amino acids. Therefore, different sources to obtain the daily recommended dose of protein is not needed. Also, amaranth lacks gluten, which is a problematic protein contained in many true grains. Dietary fiber and essential amino acids, including lysine which has clinically shown potential for cancer treatment, are prominent in amaranth. It also contains relatively low cholesterol levels. The oils in amaranth have been shown to help prevent and treat those with hypertension and cardiovascular disease. Regular consumption of amaranth can reduce cholesterol levels and lower blood pressure. Amaranth has been noted to help boost the body’s immune system. Some research has even shown that grain amaranth shows promise in the prevention of premature greying of the hair.
