Psoriasis, commonly known as psoriasis, is a common recurrent inflammatory skin disease characterized by the appearance of red scaly patches of varying sizes and clear boundaries, covered with a large number of dry silvery-white scales, accompanied by itching of varying severity. The onset of psoriasis is related to genetic factors, infectious factors, metabolic disorders, immune dysfunction, mental stress and other factors, and there is no cure yet. The actual “psoriasis” patients often have severe itching, and when the condition is serious, there will also be dry skin, pain, so close clothing should choose pure cotton, loose, soft clothing. The actual fact is that you will be able to get a lot more than just a few of these. Food 1, appropriate amount of protein, vitamins and a variety of trace elements. Because psoriasis is a chronic erythematous scaly skin disease, patients often have a large number of flakes shed, these shed flakes have a high content of protein and lipid, resulting in a large loss of body protein, and because the epidermal cell metabolism is accelerated, consuming a large number of vitamins and trace elements, causing a relative lack of nutrients in the body. It is recommended that patients drink 1-2 bags of milk every day, while eating oatmeal, tomatoes, black fungus, yellow vegetables, green tea and other foods and vegetables rich in vitamins and trace elements. 2, eat less beef, lamb and other red meat products, because psoriasis is a chronic inflammatory skin disease, some studies have shown that beef, lamb and other red meat products can lead to an increase in arachidonic acid and aggravate inflammatory skin disease.

Ethanol intake was associated with chronicity, severity and treatment failure of psoriasis. Patients who consume >80 grams of alcohol per day have poor treatment outcomes. Alcohol consumption also decreases patient compliance with treatment.
