To be exact, Europeans and Americans simply don't know how to eat sea cucumbers. This is a question of food culture. Not eating sea cucumber abroad does not mean that the nutritional value of sea cucumber is not recognized. People in China eat sea cucumber, bird's nest, ginseng and animal whip. It originated from the traditional Chinese medicine culture in China. Physicians of past dynasties integrated the efficacy of Chinese herbal medicine and animal medicine, and put forward the dietotherapy principle of "strengthening the body resistance, tonifying kidney and yang, nourishing yin and enriching blood", such as sea cucumber, which is positioned as a big seafood. Can be used for treating impotence, premature ejaculation and nocturnal emission caused by kidney deficiency; Anemia and flaccidity caused by blood deficiency; Constipation and polydipsia caused by yin deficiency; Weakness and limb drowsiness caused by spleen deficiency. It is also suitable for diabetes due to yin deficiency and internal heat, tuberculosis and hemoptysis. Its medicinal value has also been proved by modern medicine. And these theories are incredible to westerners. The concepts of "kidney deficiency" and "vitality" are unfamiliar to them. In their eyes, ginseng still belongs to the grassroots, not to mention the echinoderm such as sea cucumber. In recent years, there are many reports about the anti-cancer research of sea cucumber abroad, and the medicinal and nutritional value of sea cucumber is gradually recognized by the world. Sun Yat-sen's exposition on China's diet health —— Reading "Taking diet as evidence" in the General Plan for the Founding of the People's Republic of China: Sun Yat-sen, who is familiar with Chinese and western food culture and science, commented on China's diet as "the progress of diet is still lagging behind civilized countries. The food invented by China is abundant in Europe and America. Moreover, China's excellent cooking methods are not comparable to those in Europe and America. As for the eating habits of China people, it is nothing more than the latest theory invented by the most knowledgeable medical and health scientists in Europe and America. " "Such as ordinary daily necessities, such as lily, fungus, tofu, bean sprouts and other products, are all good vegetarians, and European and American countries do not know that they are food. As for meat and the internal organs of six kinds of animals, China people think it is delicious, while the British and Americans didn't eat it in the past, but they also think it is delicious in recent years. " "Some westerners despise China people for eating pig blood, and think that barbarians are thick and evil. What medical health workers have studied now is that pig blood is rich in iron, which is not the top grade of tonic. " Sick people can eat solid food, and people who are not sick can eat healthy food. "For China cooking, Mr. Sun thinks it is also an art:" The pleasing paintings and pleasant sounds are all fine arts; There is also a pleasing taste, so why not? Being a chef is also an art. "China's food culture is a wonderful flower, which integrates color, fragrance, taste, shape, nourishment (food texture) and nourishment (food health), making people enjoy sight, touch and taste comprehensively, and constitutes the cooking characteristics of China with delicacy as the core and health as the purpose. It has exquisite materials, exquisite knife work, realistic modeling, bright colors and ingenious combination, and has the same origin as food nutrition, food nourishing and food regulation, and has an indisputable historical position. Mr. Sun believes that this is the representative of Chinese civilization: "The art of cooking is born in civilization, and if you don't have a deep understanding of civilized people, you can't distinguish the taste; "Taste is not fine, not cooking. The beauty of China's cooking also shows the depth of civilization evolution. " Regarding the position of Chinese food in the world, Mr. Sun's evaluation is that "the cooking skills of western countries are not as good as those of France, and the degree of civilization of western countries is not higher than that of France. But before the integration of Chinese and western markets, westerners only knew how to cook, and France was the highest in the world. When you taste China, you will be crowned with China. " "In recent years, wherever overseas Chinese go, China's diet is prevalent. There are hundreds of China restaurants in new york, USA. In every American city, there are few restaurants in China. What loves China's aesthetics is madness to the country. " Mr. Sun advocates vegetarian tea, tofu and vegetables in China diet, which are beneficial to health. He said: "China is not only rich in food inventions, but also beautiful in cooking methods, which is not comparable to other countries; China people's eating habits are scientific and healthy, especially ordinary people in other countries. In China, ordinary people drink green tea, eat light rice and use vegetable tofu. These foods are tested by today's hygienists as the most healthful foods. Therefore, people who eat less than wine and meat in inland China tend to live longer. China has a prosperous population, and China people often have great ability to resist diseases and epidemics, but it is also a coincidence of diet and hygiene. If we can make more efforts, improve and progress in science and health, the race in China will be stronger than today. Westerners advocate vegetarianism based on scientific health knowledge, in order to prolong life. However, its vegetarian products are not as exquisite as those in China, and its seasoning methods are not as exquisite as those in China. Therefore, most of its enthusiastic vegetarians eat too many vegetables, which leads to insufficient nutrition and in turn hurts the living. In this way, the wind of vegetarianism is hard to break across the country. Vegetarians in China must eat tofu. Tofu is the meat in plants, which has the function of meat, but it is not poisonous to meat. Therefore, vegetarianism in China has become a habit, which is not advocated by scholars. Europeans and Americans drink turbid wine, while those who eat foul smell learn from each other. Therefore, although there was scientific advocacy in the past, there will be severe prohibition of alcohol in the future. For example, Russia and the United States have recently strictly banned alcohol, which will not change for a while. As far as diet is concerned, China's habits are superior to those of other countries. This is the most important thing in life. China people have no time to wait for inducements, but it is a great blessing to make Xi a natural place in A Zhi. We should be conservative and not lose, thinking that teachers in the world can also guide us. Dr. Sun Yat-sen is not only a great revolutionary, but also a famous physician. He is not only good at western medicine, but also has research on Chinese medicine and diet nutrition. Mr. Sun once created "Siwutang", which combines the essence of four vegetarian dishes: day lily, fungus, tofu and bean sprouts. Teacher Sun discussed the health hazards of overeating from the perspectives of biochemistry and nutrition. It compares "cell" to the original son of a creature and takes the original name "Shengyuan" from the origin of the creature. " The exquisite and magical personal structure is born for it; The intelligent perception of human nature is also born from this; The state of animals and plants is strange and incredible, and so is the structure of the source. "Shengyuan has built the kingdom of life. The metabolism of biogenic elements requires energy (fuel) and basic substances (materials). " If food has enough fuel in the body, the rest is converted into fat and stored in the body for a rainy day. If there is not enough fuel in the body, Shengyuan must take the fat stored in the body as fuel; When the fat is exhausted, the muscles are taken away. So people who don't have enough to eat are also thin. Materials are the nourishment of raw materials and the building materials of the body. If these substances are redundant, they will be converted into fuel instead of being stored in the body. ""There shouldn't be too much substance, too much will consume the power of internal organs and turn it into fuel. However, if its quality is not suitable for fuel, the residue left after combustion will remain in the body, and it will take a lot of effort for the kidneys to remove the residue, then the viscera in charge of other things will be overworked and the damage will follow, which is inappropriate. There are two uses of food: one is fuel, and vegetarian food is more; One is the material, and there is more meat. Too much material can be used as fuel, and too much material can't be used as material. Therefore, material can not be lacking, and lack of it will damage vitality; You can't have too much material, too much will hurt the viscera. If people all over the world can know this principle, they will think about ways to preserve health and prolong life. "In the chapter" Based on diet ",Teacher Sun introduced the calculation method of protein (light gas), carbohydrate (light carbon) and fat thermogenic nutrients; It is pointed out that "most diseases in the world come from improper diet"; In the past, "eat less gluttony"; Wine, cigarettes, opium and shoulders are "raw things"; Taking my stomach disease cured by adjusting diet as an example, this paper demonstrates the feasibility of keeping healthy by diet and "vegetarian diet is a wonderful way to prolong life", and introduces the digestion and absorption process of food and its related human tissues and organs. On the whole, Mr. Sun came to the conclusion that "from this point of view, everyone can eat and drink in his own body, even people who don't know their way all their lives;" "Everyone knows about the problem of eating food, and people who don't understand it all over the country are like that. This is enough to prove that it is not difficult, but it is difficult to know. " From the discussion of Teacher Sun's chapter "Taking Diet as Evidence", I realized that solving the problem of "knowing is easier than doing" is the key to solving "food safety" at present. Because "food safety" is concerned by the public, the government and the media, but because "what is safe food?" There are many misconceptions that general quality problems are "food safety", so many "problem" foods confuse consumers and affect the quality of life and the healthy development of the food industry.
