The ancients said, "Food is the most important thing for the people". Indeed, among all the problems facing mankind, diet is the most important and the most concerned.

In essence, the pursuit of food beauty is a kind of value pursuit. On the contrary, this difference in value pursuit leads to different food cultures. Traditional diet health preservation in China has become a food culture phenomenon because of its unique value pursuit.

China's traditional food culture pursues not only the delicious food, such as the sensual enjoyment of delicious jade plates, but also the real value of keeping fit and prolonging life. The connotation of this culture lies in nourishing the human spirit, adjusting the relationship between yin and yang and the five elements in the human body, and coordinating and balancing the internal system and organ functions of the human body, so as to achieve the goal of health and longevity. Gao Lian, a famous health care expert in Ming Dynasty, once said: "Diet is the foundation of survival. It is the combination of yin and yang, and the five elements are born together, all because of diet. So when you eat, the grain is full, the grain is full, and the blood is full. Spleen and stomach, the five internal organs of the Sect. The qi of the five internal organs belongs to the spleen, and the stomach qi is the foundation of the four seasons. Eating can replenish qi, being angry can replenish essence, and producing essence can replenish qi. Qi is enough to give birth to god, and god is enough to pass through the whole body. To think that users are also engaged in daily health care, the transaction is still relatively weak. Don't let the person who gave birth to me hurt me. The five flavors of the spleen are thieves of the five internal organs and are the way to preserve health. " (Eight Notes on Respect for Life) According to its historical origin, diet health preservation is the oldest of many health preservation methods. "The dragon tastes a hundred herbs, and the water spring is sweet and bitter, and the people know to avoid it." (Huainanzi practiced martial arts training) This shows that ancient ancestors paid attention to seeking advantages and avoiding disadvantages in their diet and exerted their subjective initiative. This kind of consciousness and behavior obviously goes beyond the instinct of animals to choose food, and contains the basic connotation of human diet health culture. According to legend, Yi Yin, the prime minister of Shang Dynasty, wrote to Tang Yejing to discuss the diet preparation and cooking methods for health preservation. During the Western Zhou Dynasty, diet regimen has become a theory based on the Five Elements Theory. Huangdi Neijing, as the founder and master of China's ancient health preserving theory and medical theory, pushed the food culture to a very important height, and summarized and put forward that the basic principles of food preserving are "harmony of five flavors" and "moderate diet". The diet health culture established in the pre-Qin period was further supplemented and improved in the Han and Tang dynasties. Zhang Zhongjing, Sun Simiao, Ho Choi, Liu Xiu and others paid more attention to exploring the health value of various foods, and paid special attention to food hygiene. During the Song and Yuan Dynasties, Chen Zhi, Zou Xuan, Hu Sihui and others emphasized the way of food supplement. Hu Sihui, a dietetic doctor in Yuan Dynasty, wrote the first monograph on dietetic health and nutrition in China, "Diet Prescription", which selected the essence of diet and dietotherapy in past dynasties and paid attention to dietary taboos, which was really a milestone in ancient dietetic health culture works. During the Ming and Qing Dynasties, dietotherapy health care developed to a very mature stage, and many famous dietotherapy health care experts appeared, such as Li Yong and Gong Tingxian in the Ming Dynasty, Cao Tingdong and Gu Zhongze in the Qing Dynasty.

In a word, China's ancient diet health culture has a long history, and it has accumulated very rich contents and methods, which is a treasure in the world diet culture. Exploring its value orientation, China's diet health culture is unique in the pursuit of health and health preservation. Exploring its diet culture structure, food nourishment and dietotherapy, drug nourishment and drug therapy are two interdependent and closely related levels, and food and drugs are closely related in many cases. Judging from the main principles of China's healthy diet, there are two main points: one is to eat well, and the other is to eat well. The former includes the requirements and principles of food compatibility, taste and cooking, especially the requirements for food; The latter is about eating methods and requirements. Eating and drinking well includes the principles of reasonable compatibility, harmony of five flavors, proper cooking and light diet. Diet should be moderate, including moderate and economical diet, such as eating according to time, adjusting according to time, avoiding food, eating properly and maintaining after meals. These are the summary of life experiences of the clever ancestors of Yanhuang for thousands of years.
