The dietary life of human beings is a comprehensive reflection of the benchmark of civilization and cultural features in a certain historical stage. The brilliant development of China's food culture mainly benefits from the long-standing origin and rich content of food thought. This profound and solid ideological origin is manifested in four principles of basic theory, five characteristics of culture and ten styles.

1. Four principles of the theory of food culture:

1. Integration of food and medicine

Due to the mutual help and influence of nutrition in diet and medical diseases, the important principles of China's food thought were derived from the practice and preliminary understanding of "homology of medicine and food", forming a valuable tradition of "integration of food and medicine" with China characteristics.

In the Zhou Dynasty, a professional "food doctor" appeared in China. As a nutritionist in Wang Ting, the "food doctor" had a high status, which was the origin of modern nutritionists. At that time, special management and research institutions were set up for this purpose.

At that time, there were also a number of monographs on dietotherapy, such as "The Prescription of Preparing for a Urgent Need"-Sun Simiao, "Dietotherapy Herbal Medicine" and so on.

Second, keep healthy by eating

Laozi and Zhuangzi advocated using the "guiding" qigong of "expelling the old and absorbing the new" to keep fit and live longer.

Ge Hong, a famous health care practitioner in the Eastern Jin Dynasty, advocated that "health care should be based on no injury".

Third, Benwei advocates

paying attention to the natural taste of raw materials and paying attention to the original flavor of food. This is the core principle of China's cooking.

IV. Confucius' Esophagus

The so-called Confucius' Esophagus means "never tired of eating fine food, never tired of eating fine food"

2. Five characteristics of national food culture:

1. Extensive selection of food raw materials

2. Rich selection of food

3. Flexibility in dish making

4. Regional style.
