The human body in order to maintain normal activities, the need for many nutrients, but can be divided into protein, fat, carbohydrates, vitamins, minerals, dietary fiber and water, according to some scientific and technological research, many of the diseases that endanger human health, such as diabetes, obesity, cancer, and so on and the current people's diet varieties simple related to the world's undernourished people are still about 15% of the world's population. The number of undernourished people in the world is still around 15%. Moreover, the meaning of the word nutrition proposed by our ancestors is not entirely consistent with the word Nutrition used in some foreign countries. This term in the West refers to the meaning of nourishment and sustenance, and does not explicitly include the ancient Chinese word "camp". The word "camp" does not explicitly include the ancient Chinese word "camp", "camp" is to seek to operate also, one of the camps, Wei, Qi, blood in Chinese medicine also.

1. Nutritional composition of Chinese food

The traditional diet of the Chinese population is based on cereal things as the main source of energy, which provides about 75% of the total calories of the diet, the protein provided by about 66% of the total amount of protein, and animal foods provide about 8% of the calories provided by about 11% of the protein. Such a dietary structure in nutrition is called high cereal diet, which contains a certain amount of vegetables, fruits, but due to the traditional cooking techniques of Chinese residents and the requirements of taste, many vegetables in the process of washing, cutting, cooking and so on, there are a large number of healthy substances beneficial to human health is removed. As the protein content of cereal food is not high and its amino acid composition is not perfect, the protein provided by this type of diet is not only insufficient in quantity, but also low in physiological value; insufficient intake of calcium and low utilization of trace elements such as iron and zinc, as well as insufficient vitamins, are also common problems in this type of diet. With the restructuring of diets, food consumption has been declining year by year, while animal food consumption has been on the rise. However, according to the results of the 1992 National Nutritional Survey, animal food consumption has exceeded cereal consumption in some of the more affluent families. This "Westernized" or "affluent" diet provides too much energy and fat and too little dietary fiber, which is detrimental to the prevention of some chronic diseases.

In order to improve the deficiencies in the traditional dietary structure, the Chinese Nutrition Society and the Institute of Nutrition and Food Hygiene of the Chinese Academy of Preventive Medical Sciences formed a committee of experts to design a Balanced Dietary Pagoda for Chinese residents based on the Dietary Guidelines for Chinese Residents combined with the characteristics of the dietary structure of Chinese residents.

The Balanced Diet Pagoda proposes a nutritionally ideal dietary pattern, and the amount of food it suggests, especially the amount of milk and beans, may still be a certain distance from the actual diets of the majority of the population, and may be a long way away from certain poor areas, but it is indispensable in order to improve the dietary nutritional status of the Chinese population, and it should be regarded as a goal to be striven for and gradually achieved. The goal is to achieve it gradually.

2. Nutrient composition of Western food

Currently, the developed countries are upwardly mobile diets, with meat as the main source of energy, which is characterized by too much energy-containing densities, rich in fats and sugars and a lack of complex carbohydrates. Although the supply of nutrients is insufficient, will lead to nutritional deficiencies, a variety of nutritional deficiencies, but if the nutritional intake of too much, will cause excess nutritional intake, which not only aggravates the burden on the digestive organs, caused by gastric disorders, at the same time, this is also the obesity, cardiovascular disease and the root cause of diabetes, is also not conducive to physical health. Western countries now also recognize this problem, and therefore generally recommend China's dietary structure.

It is worth mentioning that in the "What to eat? How to eat? The question of "what to eat and how to eat it?" is not the same in China and the West due to differences in various aspects. Chinese people pay more attention to the requirements of taste in their diets, while Westerners pay more attention to the nutritional mix and match.

See, reasonable diet and balanced nutrition is the key to protect human health.

II. Comparison of Chinese and Western food flavors

The beauty of the dishes, when the flavor theory, and the flavor of the first in the taste. The national recipes of a country, to a certain extent, reflect some of the characteristics of the nationalities of the country, such as German cuisine is affordable, rich in family meal flavor, which demonstrates the simplicity of the German nation's character and pragmatic spirit.

The Chinese and Western countries have different social and cultural backgrounds, and the requirements for food in terms of taste are not the same.
