More than 7,000 years ago, the study of nutrition began in ancient China. 7000 years ago, the initial research of human beings began with whether food was poisonous or not. The purpose of Shennong tasting herbs is to determine whether they are poisonous or not. 3000 years ago, the society was stable, the Yellow Emperor was born, and the study of diet advanced. There was once a book, Huangdi Neijing, which recorded the core of food: five grains are the supplement, five fruits are the help, five animals are the benefit, and five dishes are the filling. Take its smell and taste to supplement the lean qi. That is to say, 3000 years ago, our ancestors thought that Gu Mi must eat, fruit should be eaten together, and meat should be seasoned. All kinds of vegetables are energy-supplementing foods, so they are suitable for the human body when eaten together. Generally speaking, it's four parts vegetarian and one part meat. This is a wonderful proportion, which conforms to the laws of nature. Two thousand years ago, the father of western medicine, Xi Bocklaro, put forward the principle of diet: "Treat your food as medicine, not your medicine as food." It is the medical idea of eating more and taking less medicine to prevent diseases in advance.
In about 16 16, Descartes founded analytic geometry and set up a new thinking viewpoint. His main contribution to modern nutrition is to decompose food as a whole and determine the ideological basis of modern nutrition. As soon as his thoughts came out, human beings began to think in decomposition, decomposing human organs to study and decomposing food to study. Mankind has entered the history of decomposition.
At that time, China had not established decomposition thinking until about 16 16. In addition to Li Shizhen and other famous medical experts, another food research has been established, which is about the classification of temperature, heat and cold of food. Compendium of Materia Medica consists of 52 volumes, divided into 16 parts and 60 categories. It was written in 1578, representing the peak of dietotherapy in ancient China. The last one is based on 1900. According to Descartes' thought, westerners break down food and extract carbohydrates and other nutrients. Since then, there have been studies on six nutrients. After 1950, China also began to learn the tracing history of these six nutrients, while China did not make any major innovations. . This is the development history of nutrition.
The origin of modern nutrition began with the discovery of carbohydrates in 1900, and gradually became a professional discipline. China had the concept of nutrition for a long time. For example, the raw materials and cooking methods in jiaozi, China, are in line with the China food culture with color, fragrance and taste while ensuring that all kinds of nutrients are complete and not lost. This shows that China culture is profound.
