Now we will share the general J basic knowledge about contraindication as follows. “Avoidance of food” refers to the dietary taboos when taking medicine. All kinds of food have their own properties, which will have certain effects on the occurrence and development of diseases and the therapeutic effects of drugs. 1, when taking Chinese medicine diet taboos include disease food taboos and medicine food taboos: disease food taboos is based on the nature of the disease to pay attention to the “taboo”, such as damp-heat evidence should avoid spicy, greasy, fried food, and cold evidence should avoid eating cold, cold things. The diarrhea of tumor patients mostly belongs to coldness, so they should choose light and easy to digest warm or flat food. Food taboo refers to the food taboo that should be observed during taking Chinese medicine. For example, avoid radish when taking ginseng, and avoid amaranth when taking turtle shell. Do not drink strong tea when taking Chinese medicine, because strong tea contains a lot of tannic acid, which will reduce the efficacy when taken with Chinese medicine, and you should mainly drink plain water. You should not eat chili pepper when taking Chinese medicine, especially if you have heat-related illnesses, and you should not eat chili pepper when taking medicine to clear heat and cool blood or nourish Yin and lower fire, otherwise it will make the treatment ineffective or weaken the efficacy. The curd contains a protease enzyme that can counteract the medicinal effects of Chinese medicine, which also requires special “taboos”. When taking Chinese medicine decoctions and pills, avoid raw, cold, greasy food. The general term “hairy food” refers to food that should not be eaten during the treatment of a certain disease. According to their properties, Chinese medicine classifies them as “hairy foods”, such as ginger and garlic, and shrimp and crab as “windy foods”. Whether “hairy food” needs to be “taboo” or not, should be discussed according to the method of Chinese medicine to identify the evidence. For example, asthma patients, usually can be free to eat and drink, but during an asthma attack, eggs, milk, fish and shrimp and other high-protein foods become aggravated “hair”, should be “taboo”. In addition, suffering from scabies, skin disease, avoid eating saltwater fish, shrimp, crab and mutton, pork and other foods; edema disease less salt; hepatitis and liver function damage patients avoid eating spicy, spicy, greasy. 2, a lot of taboos are relative, according to the physique and the specific circumstances of the body at the time to develop. In addition, the taboo food includes avoiding food that is easily contaminated by carcinogens or eaten for a long time with carcinogenic potential, that is, burned, baked, smoked, pickled, moldy and soaked food. However, it is not absolutely not to eat, eat less can be completely. It should be noted that foods containing hormones such as royal jelly, hashish oil, placenta, etc. are completely forbidden. Jin Yuan era Zhang Zhihe once said: “stomach for the sea of water and grain, can not be deficient, deficient is a hundred evil into carry on, or think meat and vegetables, although the opposite of the disease can also be slightly eaten.” Meaning: the stomach is the main place of digestion, if you do not dare to eat, then the evil will attack, if you want to eat something, although his disease is a little incompatible with it, but a little less can still be eaten. Diet and medicine are two different things.

Beans have phytoisoflavones, which are harmless to human body and have an antagonistic effect with estrogen in the body. 3.Adequate amount of fresh fruits. However, people with cold spleen and stomach or weak spleen and stomach (loss of appetite, frequent bloating and diarrhea, feeling indigestion after eating, etc.) should not eat more, or should not eat before the spleen and stomach function returns to normal. 4, meat.
