There is a famous saying in Huangdi Neijing (Su Wen). On anger rising to heaven), "the change of paste beam will lead to great virtue." The meaning of this sentence is that eating "fat, sweet, thick and greasy" food often leads to the accumulation of phlegm and heat in the body, while "eating too much delicious food" means that people who eat too much delicious food are prone to large boils. Modern times call this phenomenon "the disease of civilization" and "the disease of wealth". The reason why so many people suffer from diabetes now is because of the disorder of body metabolism, which is mainly related to the change of eating habits. There is no doubt that eating too much big fish and meat will cause the evil consequences of the disease. Why are there many ulcers and rotten legs in the late stage of diabetes? It has something to do with this. At the same time, excessive intake of high-calorie food is harmful to human health, the most serious is fatty liver, in addition to cardiovascular and cerebrovascular diseases, heart failure and other long-term complications.

? From the perspective of medical dietary theory, the "change of the cream beam" mainly refers to the gradual change of people's dietary structure from a plant-based protein to an animal-based protein, with more high-calorie food and less low-calorie food, which leads to the increase of related nutritional chronic diseases, among which diabetes is a more serious one. Therefore, in order to prevent diabetes, we should first pay attention to changing the unreasonable diet structure and develop the habit of balanced diet and reasonable nutrition. Don't eat meat food, eat it with other plant foods.

In The Analects of Confucius, the Rural Party, Confucius put forward the dietary requirement of "food essence is not greasy, food essence is not greasy". The finer the particles, the better. The finer the meat, the better. The amount of meat eaten at the table should not exceed the amount of rice and flour, and wine can be drunk at will, but not at all. This should also be very reasonable today.
