For a long time, patients with psoriasis have many dietary taboos, but due to unscientific taboos, the body lacks some necessary nutrients, and the immune level is further reduced. The psychological pressure caused by taboo eating irritants is not conducive to the good prognosis of the disease. These are all caused by the harsh and blind taboos of the people at present. Should psoriasis patients avoid eating? What is the right taboo? "Taboo", commonly known as taboo, comes from Chinese medicine saying that Chinese medicine should pay attention to dietary taboos in clinic so as not to affect the therapeutic effect. When seeking medical treatment and health care, we should pay attention to "taboos", that is, pay attention to the advantages and disadvantages of drugs and food, which is also an important method of scientific health care. As the saying goes, "If you don't avoid taking medicine, you will break the doctor's leg", which fully illustrates the importance of taboos. There are taboo records in many TCM documents. Psoriasis, as a common inflammatory and proliferative skin disease, is closely related to dietary factors. Of course it needs to be avoided, but it needs to be avoided scientifically. You can also apply the theory of traditional Chinese medicine to treat food based on syndrome differentiation and carry out certain dietotherapy. Studies have shown that drinking tea, eating pickles, bean products, egg products and eating vegetables and fruits have nothing to do with psoriasis; Eating fat, animal oil, alcohol and food allergies can induce psoriasis, while eating sweets, vegetable oil and lean meat may have the effect of preventing psoriasis. Long-term consumption of animal oil and fat is easy to induce psoriasis, and people who eat vegetable oil and lean meat can alleviate psoriasis. This may be related to the high content of saturated fatty acids and cholesterol in animal oil and fat meat, the low content of saturated fatty acids and cholesterol in lean meat and the high content of essential fatty acids in vegetable oil. Eating animal oil for a long time causes the body to lack essential fatty acids, and eating vegetable oil makes the body have enough essential fatty acids. Essential fatty acids play an important role in maintaining cell integrity, maintaining normal physical characteristics of biofilm and normal metabolism of cells. Another study shows that the recurrence rate of patients who don't taboo irritating food is lower than that of patients who don't taboo irritating food. Clinically, it is observed that withdrawal stimuli can temporarily aggravate the condition of some patients, but from a long-term and dialectical point of view, the advantages outweigh the disadvantages. Only when the body is constantly stimulated can it gradually passivate its response to stimulation, and it is not easy to relapse after being stimulated again after recovery. On the contrary, if it is strictly forbidden to eat irritants during treatment, it will be easy for the disease to recur once it is cured. Therefore, avoiding eating stimulation should be the need of treatment. Of course, alcohol should be taboo. Some foods, such as beef and mutton, have been proved to contain more arachidonic acid, which affects the recovery of psoriasis and should be properly taboo in the acute stage. Some patients are allergic to fish, shrimp and eggs, and they should also avoid eating. In a word, it is a misunderstanding in the treatment of psoriasis for a long time to strictly prohibit eating irritants. The theory of traditional Chinese medicine emphasizes that food is the first thing in treating diseases, not medicine. It can be seen that traditional Chinese medicine attaches great importance to treating diseases with food. Traditional Chinese medicine believes that drugs are cold, cool, warm, bitter and salty, and food is no exception. Food can not only keep healthy, but also cure diseases. The characteristic of TCM treatment is "syndrome differentiation and treatment", and TCM dietotherapy is also based on TCM syndrome differentiation theory, emphasizing "syndrome differentiation and food application". Eating according to syndrome differentiation is to decide taboos according to the patient's condition and nature. The choice of patients' food should be based on the four flavors and meridian tropism of the food itself, combined with factors such as illness, weather, climate, geographical environment and living habits. The treatment principle of traditional Chinese medicine is "cold is hot, and heat is cold", and foods or taboos are selected according to the cold and heat nature of diseases. The same is true for the diet therapy of psoriasis: patients with "blood fever" mainly need to avoid hot foods, such as mutton, dog meat, shrimp, eel, onion, ginger, garlic, pepper, orange and litchi. And eat duck, asparagus, lotus root, watermelon, pear, mung bean, water chestnut, wax gourd and fresh grass. Patients with "blood deficiency and blood dryness" should avoid spicy and fragrant food, and should eat wheat winter porridge, boiled eggs with radix rehmanniae, boiled eggs with angelica brown sugar, auricularia auricula, red dates, sesame seeds and other products that nourish blood, nourish yin and moisten dryness; Patients with "blood stasis" should mainly avoid high-fat foods and eat less foods with astringent and qi-blocking effects, such as lotus seeds, Gordon Euryale seeds, pomegranate, dark plum, glutinous rice, lentils, cowpeas and broad beans. And should eat raw lotus root, peanuts, hawthorn, radish, leek, brown sugar, vinegar, peaches, etc. In short, the taboo of psoriasis is selective and scientific, which is based on the dialectical eating method of traditional Chinese medicine, not what people think, that is, people with acute and chronic diseases must avoid eating all "hair".
