There is a famous saying in traditional Chinese medicine: "Disease comes from the mouth." This sentence not only points out the source of the disease, but also emphasizes the importance of diet for physical health. In traditional Chinese medicine theory, food is the main source of nutrition for the human body, but it is also the source of diseases. Improper diet, excessive consumption, and unclean food can all lead to the occurrence of diseases.
Traditional Chinese medicine believes that the digestive system of the human body is a key link in dietary nutrition. If there are problems with the digestive system, it will affect the body's absorption and utilization of food, leading to the occurrence of diseases. Therefore, traditional Chinese medicine emphasizes moderation in diet, avoiding overeating and excessive consumption of stimulating foods.
中医有句名言：“病从口入。”这句话不仅指出了疾病的来源，也强调了饮食对身体健康的重要性。在中医理论中，食物是人体营养的主要来源，但同时也是疾病的来源。饮食不当、过度食用、食物不洁等都可能导致疾病的发生。

中医认为，人体的消化系统是饮食营养的关键环节。如果消化系统出现问题，就会影响人体对食物的吸收和利用，从而导致疾病的发生。因此，中医强调饮食要有节制，避免暴饮暴食和过度食用刺激性食物。
