Oat, as an ancient food crop, grows in the alpine region at an altitude of 1000 ~ 2700 meters, and has the characteristics of high protein and low carbohydrate. At the same time, oats are rich in soluble fiber and insoluble fiber, which can absorb a lot of cholesterol in the human body and excrete it, which conforms to the dietary concept of "overeating" of modern people. Moreover, oats contain soluble fiber with high viscosity, which can delay the emptying of stomach, increase satiety and control appetite;
