Coarse grains are flat foods, and their tissues are not easily absorbed by human body, which makes them have the physiological functions of improving microbial colonies in gastrointestinal tract and producing low calories, thus having the following ten physiological characteristics:

① Coarse grains are flat foods, and long-term consumption of coarse grains can avoid the occurrence of fever. Because most human diseases belong to warm diseases, such as colds, dysentery, hepatitis, psychosis, diabetes, cancer, nephritis, rheumatism, chronic bronchitis, boils, hypertension and so on. Therefore, eating coarse grains can avoid most human diseases.

② Prevention and treatment of cardiovascular and cerebrovascular diseases. The combination of coarse grain tissues and bile salts can reduce intestinal and hepatic circulation, limit the production and absorption of cholesterol, and promote its excretion, which can prevent and adjuvant treat diseases such as hypertension and atherosclerosis. For example, pectin combines with excess cholesterol to promote its excretion, make cholesterol metabolism normal, and maintain the health of cardiovascular system.

③ Function of preventing and treating diabetes. Coarse grains also contain starch, but eating coarse grains will not cause blood sugar to rise. The reason is that the cell wall of coarse grains is not easily destroyed by human body.

④ The function of treating constipation. The tissues of coarse grains contain a lot of dietary fiber. After metabolism, dietary fiber can produce laxative hydroxyl compounds, promote intestinal peristalsis, shorten the retention time of feces in the intestine, and make the stool unobstructed.

5 lose weight. Dietary fiber of coarse grains can regulate digestion and absorption function, prolong the residence time of food in stomach, delay the appearance of digestible sugar in small intestine, affect the diffusion of nutrients to intestinal mucosa, and thus delay the absorption of nutrients. Dietary fiber can produce satiety, avoid excessive intake of calories, fat and carbohydrates, and has the function of preventing and treating obesity. At present, the number of obese children in China is increasing with the growth of children's age. Children's obesity reduces their physical and mental level and becomes a hotbed of adult diseases in the future. Therefore, families and kindergartens should provide coarse grains as staple food for obese children. For example, corn, with high nutritional value, is a good satiety food and can be eaten by obese children.
