Food therapy is a treatment method under the guidance of Chinese medicine theory, the application of the food’s sexual taste and the composition of the internal organs, to achieve the harmonization of qi and blood, balance yin and yang, prevention of disease, fitness and prolongation of life. Chinese medicine believes that “a body, yin and Yang run, the five elements, not due to diet.” As early as in the “Nei Jing” there is a discussion on food therapy: “big poison cure ten to its six, poisoning cure ten to its seven, often poison cure ten to its eight, non-toxic cure ten to its nine, fruit and meat, vegetarian dishes, food to nourish all of them. The materia medica for truth” said: “Although food is a tool for nourishing people, but also in the human internal organs have appropriate not. Cover thing has cold and heat, as if the human internal organs have yin and yang. Dirty yang and not about the nature of the cold things for the concord, it is dirty its benefit yang carry on. Dirty yin and not on the sex of the hot thing for the economy, it is dirty its benefit yin carry on. Dirty yin and yang both see the evidence, but have to cold not hot things to think of the transfer, then the dirty its benefit mixed and uneven carry on. People only know to mouth is sweet, to belly is fruit, and do not care about the entrance of food, equal to the medicine of the treatment of disease with a reason. Combined with the person’s internal organs beneficial, but can be disease health; not in the person’s internal organs detrimental, and that increase disease and promote death. This food so see the theory in the formula book, and with the drug and transmission.” This shows that Chinese medicine recognized early that food also has its two sides, and mentioned the same important status as the two sides of the drug, it can be seen that the degree of importance attached to the pros and cons of diet is extraordinary. Adequate is nourishing, unsuitable is harmful. The so-called suitable and unsuitable contains many elements, including the amount of the amount of hot and cold properties of food, etc.; in terms of the nature of the food flavor attribution, but also accumulated a wealth of experience; and in food therapy is also very careful, there are strict taboos. Chinese medicine has long recognized that the diet should not be excessive, nutrition should be comprehensive, not partial food, and the diet should be suitable for cold and temperature, and put forward different approaches to health in the four seasons, different regions, different seasons should have different diets. It is also appropriate for each person and for each body type; there are also detailed discussions on dietary therapy and dietary taboos. In terms of food therapy, we can say that we are far ahead of the West.
