China's traditional diet pays attention to balance, and puts forward that "the five grains should be raised, and the loss of beans is bad; Five animals should be beneficial, and excessive ones will be harmful; Five dishes are always prosperous, fresh, green, yellow and red; Five fruits to help, strive for less. Describing in modern language is to maintain the biodiversity of food sources, mainly cereals; Eat more vegetables, fruits and potatoes; Eat enough beans and their products every day; Fish, poultry, meat, eggs, milk and other animal foods should be in moderation.

The traditional dietary structure in China is very reasonable, but the dietary structure of China people is becoming more and more westernized. The data show that from 1997 to 2002, among the ten kinds of food consumed by Chinese residents, the consumption of grain and beans decreased by 2.6% and 6.8% respectively, the consumption of sugar food increased by 42. 1%, and the consumption of vegetable oil, meat and eggs increased by more than 20% respectively. The emergence of this situation is related to the proliferation of foreign fast food, which is mostly fried and baked, with a high proportion of meat. This wrong orientation of "eating meat is nutritious" is an important reason for the westernization of diet structure. In fact, about 60% of food calories come from carbohydrates, 25% from fat, and 12% ~ 15% comes from protein. Foreign fast food is characterized by three highs and three lows, that is, high calorie, high fat, high protein, low minerals, low vitamins and low dietary fiber. Because of the serious imbalance of nutrition, international nutritionists call foreign fast food an energy bomb and junk food.

In fact, while some people in China are keen on westernization of diet, the oriental diet structure represented by the traditional diet structure in China has attracted more and more attention. During the period of 1989, the United States Senate held an unprecedented hearing on dietary nutrition, and listened to the results of a six-year cooperative dietary survey conducted by Cornell University, Oxford University and Chinese Academy of Preventive Medicine in China. The conclusion is that the traditional diet structure in China is very beneficial to health.

Generally speaking, the traditional dietary structure in China has four advantages. First of all, the main and non-staple foods are clearly defined, and the traditional diet attaches great importance to the health care function of grains. The second is to pay attention to the health function of fresh vegetables. China's traditional diet has a wide source of fresh vegetables and a large consumption. "Eating without green" has become the golden rule of China's traditional diet. China residents eat about 500 grams of fresh vegetables every day, only 80 grams in Germany, 83 grams in Britain, about 100 grams in the Netherlands, [NextPage] 0/02 grams to 103 grams in the United States and 0/20 grams in France. The third is to emphasize "no meat a day, no beans"; Dietary principle of "green vegetables and tofu are safe" Fourth, our traditional diet insists on low-temperature cooking. Such as cooking steamed bread, rice, noodles, jiaozi and porridge. , is carried out in water environment, the temperature of 100C is much lower than that of baking, and cooking is also completed in a short time. This cooking method not only helps to keep the nutrients of vegetables from losing, but also meets the needs of dishes.

Therefore, we should adhere to the traditional diet structure of the Chinese nation, learn the methods of dietotherapy, eat more natural foods made by God and eat less artificially processed foods.
