Many patients with skin diseases will ask doctors if they need to avoid eating. Indeed, there are many skin diseases in clinic that need dietary adjustment. Such as tinea cruris, eczema, urticaria, atopic dermatitis, neurodermatitis, psoriasis, pityriasis rosea, lichen planus, erythroderma, seborrheic dermatitis and other common and frequently-occurring diseases, the incidence of which is closely related to diet, and the illness can be aggravated by eating irritating food or hair. Therefore, for those patients with food allergy, fish, shrimp, crab, sheep and other fishy hair should be restricted or fasted during the onset or after the disease is cured.

Most skin diseases have rashes. The rash has come out, and some foods are foreign proteins with hair. When this special protein is absorbed by human body, it will cause allergic reaction and damage the skin. Therefore, people with skin diseases should abstain from irritating food during taking medicine or for a long time after treatment. Otherwise, even if the skin disease is in a stable period, it will recur.

Some skin diseases, such as urticaria, neurodermatitis, pruritus, eczema, seborrheic dermatitis, allergic dermatitis and rosacea, are closely related to certain foods. During the onset or after a period of cure, fishy hair such as fish, shrimp and crab, as well as poultry food and irritating food such as onion, garlic and pepper should be restricted or fasted. Some skin diseases, such as scabies, tinea corporis, vitiligo, etc. Don't be afraid because they have nothing to do with diet.

But some patients are allergic to only one or two kinds of food, so don't go too far within the scope of taboo food. Patients can record the kind and time of food they eat, and the time when symptoms appear. If it appears 12 ~ 24 hours after eating, it is allergic food. In this way, taboos are targeted and the scope of taboos is narrowed. In daily life, it is very common for some people to avoid all so-called hair care products, no matter what kind of skin diseases they suffer from or what kind of food they are allergic to. Therefore, malnutrition affects health. Even people with skin diseases don't always avoid taboo food. After the general skin disease has stabilized for a period of time, you can try to eat allergic food, starting from a small amount, and gradually increasing the amount and frequency if there is no special reaction. After repeated desensitization, some people can no longer have allergic reactions to the original allergic food.
