Friends get together to order food, from time to time will meet so one or two people very “picky”: “This dish is ‘hair, I dare not eat. “This heat, eaten on fire.” In daily life, some taboos about food, often interfere with our appetite: “fever can not eat eggs”, “konjac more to eat will lead to the recurrence of old diseases, sores on the body can not eat”, “eat soy sauce will leave scars “…… these ingredients known as “hair”, almost can make a long list, which inevitably have some food “lying”. The folk have misconceptions about the taboos of “hairy things”, such as konjac tofu, which is a very popular cancer prevention food in Japan; the rumor that mushrooms tend to trigger liver Yang headache, induce or aggravate skin sores and swelling poison is also inaccurate, on the contrary, patients with skin diseases should eat more mushrooms. So, what is “hairy food”? There is no clear definition of “hair products” in Chinese medicine, it is a folk experience. The term “hairy food” generally refers to foods that have a warming effect and are easily irritated or allergic after eating. The former is represented by condiments such as chili, pepper, mustard, ginger and wine, while the latter is represented by beef, lamb and dog meat and seafood, which can cause allergies. Fruits, including pineapple, mango, longan, lychee, peach and other allergic or hot fruits, are also typical representatives of “hair products”. But some people are also accustomed to milk, eggs, beans, raw peanuts, tomatoes, cucumbers included in the “hair products”, in fact, may not be correct. Whether “hairy” to be dialectical view, because in some cases it is “hairy”, but other cases may not be, for a certain type of people may be, but for another type of people may not be. In fact, those who are most contraindicated to eat “hairy food” should be tumor patients. Professor Lin Lizhu, director of the Oncology Center of the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, believes that the key to whether or not “hair products” have an effect on the body is whether or not they are consumed properly. The foods that need to be avoided are different due to different body types, or seasons, environment, climate and diseases. Especially for tumor patients, excessive “supplementation” is not necessarily beneficial, and excessive “taboo” is even more undesirable, especially based on some folklore taboos, which can easily cause misuse and misconception. In Chinese medicine, it is important to identify the evidence and choose the food according to the body constitution. Therefore, it is necessary to consult the doctor or nutritionist for the food taboos and dietary therapy, and to understand the personal constitution, food flavors and contraindications, so that the good food should not be consumed excessively or daily for a long time.
