Huangdi Neijing, written in the Warring States Period, is the earliest existing medical work in China, which occupies a very important position in the history of medical development in China. It not only laid the theoretical foundation of traditional Chinese medicine, but also had an impact on the development of world medicine. Huangdi Neijing systematically discusses diet health preservation and dietotherapy, and determines clear principles and implementation methods.

Especially in the application of strong drugs, we should pay attention to the comprehensive and complete diet ingredients. This is completely in line with the viewpoint of modern nutrition. The book also points out some specific methods of dietary conditioning, dietary taboos, dietary hygiene and so on. More than half of the prescriptions in Huangdi Neijing contain food ingredients. Therefore, the book Huangdi Neijing laid a theoretical foundation for the development of diet aftercare in later generations.

Introduction to nutrition:

Nutrition is a subject that studies the relationship between human metabolism and food nutrients. By describing the history, origin, development, characteristics and level of nutrition, we can understand the development of nutrition. Nutrition has a far-reaching impact on society, family, industry, health and policy.

The United States is the representative of molecular nutrition, China is the representative of holistic nutrition, and the Japanese have their own characteristics. Although Japan is not a country with developed nutrition, a survey of 20 15 found that a system of clinical nutrition has been established in Japan. Since the 20th century, the use of various ripening agents has made food nutrients scarce and the national nutritional status worrying. These are all topics worthy of attention.
