People eat in order to get nutrition from food and maintain life.

After food is imported, it is chewed by teeth, then enters the stomach, becomes semi-liquid paste, and finally enters the small intestine for digestion. When people's digestive system is in normal working condition, people can absorb enough nutrients from food.

However, some people like to "wolf down" when eating, put food in their mouths and swallow it without chewing it carefully. This kind of food, without chewing, often increases the burden on the stomach once it enters the stomach.

The indigestion of food in the stomach will inevitably affect the digestion and absorption of food in the small intestine.

So I have to eat according to the working procedure of the digestive system. First of all, chew food with strong teeth. In the process of chewing food, our mouth will also secrete saliva. Saliva contains an enzyme that can help digest food and reduce the burden on the stomach. Chewing slowly can also enhance satiety and prevent us from overeating because of hunger. Therefore, we should eat slowly instead of "wolfing down", so that we can have a healthy body.

If a person has been eating flour and rice, he should increase the proportion of coarse grains to change his diet. On the contrary, if you keep eating coarse grains, you may get enough cellulose, but protein doesn't, so he needs to eat more flour, rice and even lean meat.

So did Confucius at that time. The reason why he put forward "never getting tired of essence" was because the food at that time was too bad, and "never getting tired of essence" was a pursuit of life. On the contrary, if we were surrounded by delicious food like ours, we would have been tired of it.

Then, in a life dominated by coarse grains, eating several meals of flour and polished rice is absolutely in line with the nutritional ratio, and this rule is still applicable, but our balance cycle is not a lifetime, but a week, and it is best to find it in this week, whether it is vegetarian or coarse grains.

For example, eat as much as you want in the first half of the week or at noon, then go home for dinner in the second half of the week or at night, which is more conducive to the balance of nutrition.
