"The way to preserve one's health is not before meals." Using food nutrition to prevent and treat diseases can promote health and longevity.

As the saying goes, "medicine is better than food." The so-called food supplement means that food supplement can play a role that drugs can't. In our country, adjusting diet is a means of keeping fit. Our ancestors realized the importance of diet preservation as early as 2000 years ago in the slave society. In the court, there are already "food doctors" who specialize in the royal diet, that is, doctors who specialize in diet recuperation.

Diet is the basic condition for human beings to maintain their lives. To make people live a healthy, happy, energetic and intelligent life, we should not only be satisfied with having a full stomach, but also consider reasonable distribution of diet to ensure that all kinds of nutrients needed by the human body are balanced and sufficient, and can be fully absorbed and utilized by the human body.

To balance nutrition, we must first develop good eating habits. Don't starve, don't overeat, don't be partial to certain foods, and don't ignore certain foods. We should also pay attention to the hygiene of diet, and avoid certain foods according to our physical condition, so as to prevent the occurrence of diseases and achieve the goal of healthy and long-lived diet.

A healthy diet depends on eating. According to different economic conditions and different physiological and pathological needs, the application of daily food can not only satisfy hunger, but also supplement nutrition, which is beneficial to health and prolong life. It is an important health preserving method that people are willing to accept.
