Hairy food is rich in nutrients or irritating especially prone to induce certain diseases (especially old diseases) or aggravate the disease. Hairy food taboos in the diet and diet treatment are important, in general hairy food is also food, moderate consumption of most people will not produce side effects or cause discomfort, but only for some special body and its related to the onset of certain diseases will be induced. Hair products such as chicken, eggs, pork, etc. are foreign proteins to the human body, and such foreign proteins can constitute allergens and lead to human morbidity. Fish, shrimp, crab itself contains histamine, which can cause increased vascular permeability, microvascular dilation, congestion, plasma exudation, edema, glandular hypersecretion and eosinophilic leukocyte increase, which leads to body metamorphosis, i.e. allergic reaction, inducing skin diseases, such as erythema, papule, blister, fever, etc. Some hypersensitive patients can even have allergic reactions to rice, wheat, corn, etc. Wine, onion, garlic, etc. can directly cause skin capillary dilation and accelerated blood flow through alcohol or volatile irritants, which can aggravate or prolong the condition of existing skin diseases. Modern clinical research has also confirmed that avoiding hairy substances is also important for reducing wound infection and promoting wound healing after surgical procedures. Therefore, if a doctor says you can eat anything when you are sick, this is somehow unscientific. Proper avoidance of food is very meaningful for the recovery of the disease.
