Diet China people's diet can be roughly divided into four categories: first, cereal is the staple food, which provides carbohydrates for the human body, accounting for 70% ~ 80% of the total heat energy; Second, meat, eggs and milk provide high-quality ingredients such as protein and iron for the human body; The third is fruits and vegetables, which provide trace elements such as vitamins A, C and iron for the human body; Fourth, high-energy foods, such as animal and vegetable oils and sugars, are best used in combination with saturated fatty acids and unsaturated fatty acids to provide energy for the human body. These four foods have their own characteristics, complement each other and cannot be inherited. Therefore, to achieve a balanced nutrition, we must "eat all" and "eat all". "Eat all" refers to all kinds of grains, fruits, vegetables, meat, eggs, cream and so on. And you shouldn't be partial eclipse. "Eat all" means eating all the roots, stems and leaves of a thing, such as celery. The nutrition of leaves is better than that of stems. It is very bad to be partial or picky about food. Try to eat a balanced diet. It is best to have vegetables, meat, eggs and milk in your daily diet. Of course, the staple food can not be ignored.

Health experts have a famous saying, "Eat seven points full and never get sick." Modern research has found that a cell growth factor called fibrous bud can promote the formation of cerebral arteriosclerosis. After a full meal, its content in the brain is tens of thousands of times higher than that before meals. Although there is a regulatory mechanism in the body to restore it to the normal level, after a long-term full meal, this factor will accumulate in the brain, making the brain dull, so there is a saying that it is "full and stunned ..." Therefore, we should pay attention to chewing slowly when eating: this will not be too full because of eating too much, and it will also help protect the spleen and stomach. There is a "hot line" between the masticatory muscles and the brain. Repeated and persistent chewing can significantly improve the thinking ability of the brain, increase the information transmission of Hz cells and improve the working efficiency of the brain, which is exactly what candidates need.

In addition, do more physical exercise during study breaks. Exercise can excite human body function, improve human immunity, completely relax body and mind from the inside out, which is most conducive to adjusting mentality and relieving stress. We should also make a good timetable.
