Dietotherapy is the use of food to prevent and treat diseases, or to promote the recovery of the sick body, specifically in the form of food. It is different from medication and ordinary diet. The relationship between food therapy and drug therapy Food therapy and drug therapy are very different. One of the most remarkable characteristics of dietotherapy is "treating diseases and strengthening the body without disease", which has basically no toxic and side effects on the human body. That is to say, the biased characteristics of food (cereals, meat, fruits and vegetables) can be used for the treatment or adjuvant treatment of certain diseases, regulating yin and yang, and making them tend to be balanced, which is helpful for the treatment of diseases and the rehabilitation of body and mind. But food is food after all. It contains all kinds of nutrients necessary for human body, mainly to make up for the constant consumption of Yin and Yang. Therefore, even if the syndrome differentiation is not accurate, food will not bring much harm to the human body. As Zhang Xichun, a famous doctor, said in "Diet therapy for patients can cure diseases and satisfy hunger", it can satisfy hunger and be palatable. If you use it to treat a disease, it will gradually heal, that is, it is not symptomatic and there will be no other diseases. " Therefore, dietotherapy is widely used, mainly for sub-healthy people, followed by patients. Dietotherapy, as an auxiliary means of drugs or other therapeutic measures, is naturally accepted with daily diet. The combination of dietotherapy and food can not only achieve the purpose of health care, physical fitness and disease prevention, but also give people sensory and spiritual enjoyment, so that people can unconsciously achieve the purpose of disease prevention and treatment while enjoying delicious food. This natural therapy is very different from taking bitter drugs. It's not as disgusting as drugs, and it's hard to persist. Easy to be accepted by people and can be used for a long time. It is especially suitable for the conditioning and treatment of chronic diseases. In addition, dietotherapy products are not as strict as drugs in dosage form and dosage, and cannot be replaced at will. Different cooking and processing can be carried out according to patients' tastes and habits to make them delicious and treat them with nutrition and delicacy. Of course, because dietotherapy and drug therapy have their own strengths, they are indispensable in the process of disease prevention and treatment. We should make good use of their advantages and apply them to different diseases or different stages of diseases. Dietotherapy and drug therapy cooperate with each other, cooperate with each other and complement each other. The characteristics of Chinese dietotherapy 1 embody the idea of putting prevention first. It is emphasized that diet is the basis of human body's fine bloating. Put forward the correct concept of "five grains for nourishment, five fruits for help, five livestock for benefit, and five vegetables for supplement", correctly select food, rationally match meals, preserve health and prevent diseases. Pay attention to dialectical (qualitative) food handling methods. Treatment based on syndrome differentiation is an important part of the basic theory of TCM, and it is also the characteristic and essence of TCM. As a part of Chinese medicine, Chinese dietotherapy also fully embodies this feature. In terms of treatment, the object of drug therapy is patients with obvious symptoms, and the indications of diet therapy are mostly in the early or late stage of the disease. The symptoms in these stages are not obvious, but there is a trend of being on the upper side of the body. It can be considered that Chinese dietotherapy is to use individual physique to give food and meals. TCM syndrome differentiation treatment includes two aspects: body deviation and syndrome differentiation. The main content of dietotherapy is to identify physical deviation. Among them, the principle of food supplement still follows the principle of "tonifying deficiency" proposed in Neijing, and foods with the function of tonifying deficiency are used for partial deficiency constitution; "Cold is hot", which is food with the warming effect of physical appliances similar to cold syndrome; "Heat is cold", and there are physical appliances with cold effects similar to heat syndrome. According to the research on human physique in recent years, it is considered that the physique of all kinds of people can be roughly divided into five categories: hazy, greasy, dry red, late cold and sleepy. Among them, hazy, greasy and stagnant foods should avoid cold and cold foods, but should choose foods with the functions of promoting blood circulation, resolving phlegm and promoting diuresis, warming yang and dispelling cold; Dry red materials should avoid being warm, but should choose foods that are cold and cool, nourish yin and produce fluid, and clear away heat and cool blood. Choosing the corresponding food according to the constitution is called treating food according to quality. 3 emphasize the four natures and five flavors of food. Traditional Chinese medicine believes that the nature of traditional Chinese medicine can be divided into four types: warm, hot, cold and cool. Food can also be divided, but the specific feeding only needs to be divided between temperature, cold and level. Its warm food is suitable for those with late cold, drowsiness, cold syndrome and yang deficiency: cold food is suitable for those with dry-heat syndrome of yin deficiency and fire excess; There are many foods that are flat, so most of them can be taken for a long time without physical prejudice. For example, eating cold food for a long time will cause spleen and stomach weakness and damage spleen yang; Long-term use of warm food will cause internal heat and internal fire to flourish, resulting in dryness and heat, and yin deficiency will cause phlegm for a long time. Five flavors: The five flavors of traditional Chinese medicine refer to pungent, sweet, sour, bitter and salty. China dietotherapy believes that food also has the above five flavors. However, these five flavors are abstract and only representative symbols of the performance and function of certain foods. They are one of the bases used by Chinese medicine to summarize and explain the therapeutic mechanism and nutritional function of food and to guide clinical medication and diet, and do not refer to the qualitative taste of food. For example, in China's dietotherapy, it is considered that chicken is sweet and has the function of urgent tonic, which can cure deficiency syndrome. It's not that chicken tastes sweet. 4 pay attention to dietary taboos. China attaches great importance to food taboos in dietotherapy. In addition to qualitative taboos, food and season, food and disease, food and food, food and medicine all have different taboos. Five people choose food according to time and place. While paying attention to syndrome differentiation and treatment, Chinese dietotherapy also believes that the preservation and treatment of food should be based on individual's age, physical condition, disease, seasonal climate, local natural environment and other factors.
