Oats are a kind of low-sugar, highly nutritious and high-energy food. They are rich in protein, oat peptides, essential amino acids, vitamins, trace elements, dietary fiber, as well as saponins (the main component of ginseng), which are lacking in cereal grains. Oats have the functions of promoting gastrointestinal peristalsis, reducing the "three highs" (high blood pressure, high blood lipid and high blood sugar), lowering cholesterol, preventing and treating colorectal cancer, preventing heart disease, anti-oxidation, nourishing the skin, and delaying aging.
