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 China, dietary regulation has a long history as a means of fitness. For example, Sun Simiao, a famous doctor in the Tang Dynasty, made great contributions to diet and health preservation. He believes that the elderly should first pay attention to diet when treating diseases. Because "food can exorcise evil spirits and soothe the nerves, so as to tonify qi and blood, but it is powerful. Even if it is used against soldiers, it is biased, making people filthy and vulnerable to foreign invasion. Therefore, if food can be used to alleviate malnutrition and properly treat diseases, it is easiest to adopt the benefits of life. "
Diet is the basic condition for human life. To make people live a healthy, happy, energetic and intelligent life, we should not only be satisfied with a full stomach, but also consider a 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.
