Whole, unrefined grains are clinically proven to reduce risk for a wide spectrum of disease states. Oats and oatmeal have long been shown to reduce bad cholesterol, and many whole grain products are allowed to make claims regarding heart health and lowered risk of coronary disease.
Lesser-known grains can also pack a potent nutritional punch. Both amaranth and quinoa contain high amounts of lysine, making them a complete protein, and also contain meaningful amounts of trace minerals such as magnesium, phosphorus, potassium and iron.
Whole grains often form the basis of functional food bars. Because they are complex carbohydrates, they have a low glycemic index compared to processed carbohydrates and offer sustained energy. In personal care, oats and soluble fiber extracted from oats are often used to soothe and protect the skin. They are clinically proven to help heal dry and itchy skin, and have traditionally been used as a functional cosmetic ingredient.
