Vitiligo is a common acquired limited or generalized skin pigmentation loss disease, caused by the loss of melanocyte function of the skin, and its pathogenesis is still unclear. The vitiligo patient’s blood and white spot site due to the lack of certain trace metal elements, and the body tyrosinase activity is reduced, affecting the melanin synthesis and metabolism, thus producing lesions. Therefore, patients should eat more food containing copper, zinc, iron and other metal elements, so that the tyrosinase activity is enhanced, and then the melanin synthesis is accelerated.
Dietary advice: usually eat more foods containing tyrosine and minerals, meat (beef, rabbit, pork lean meat), animal liver, eggs (eggs, duck eggs, quail eggs, etc.), milk (milk, yogurt, etc.), vegetables (fresh vegetables, as well as radish, eggplant, asparagus, fungus, kelp, etc.), beans (soybeans, peas, green beans, soy products, etc.), peanuts, black sesame, walnuts, raisins, snails, clams and other shellfish .
Basic contraindicated foods: (1) avoid eating onions, garlic, fish, shrimp, mutton, bamboo shoots, pickles, chili, alcohol. Should not eat spinach, because spinach contains a lot of oxalic acid, easy to make the affected area itchy.
(2) Eat less food containing more vitamin C. Because vitamin C can make the serum copper and serum copper oxidase level is reduced, affecting the activity of tyrosinase, interfering with the synthesis of skin melanin.
(3) cherries. Vitiligo patients should not eat more. The cherry is richer in vitamin C, vitamin C in the metabolic process of melanin, can make the production of melanin is interrupted, aggravate the vitiligo condition.
And the ultraviolet rays in the sun can promote melanin metabolism, so proper sun exposure can make melanocytes transfer to the cortex, so that the skin tone deepens, thus conducive to the treatment of vitiligo. But in the hot summer, the ultraviolet rays in the sunlight can inhibit the metabolism of melanin instead, which is not conducive to the synthesis of melanin, so the sunlight should be avoided in summer.
Patients other precautions: (1) mental factors: anxiety, tension, unpleasant life events, etc. can stimulate the disease, so patients should be cheerful, to have an uncontested mind and world view.
(2) environment: especially dampness, rain, water, wind chill, etc. may trigger vitiligo, which is a matter of attention.
(3) Infection: trauma, frostbite, burns are likely to lead to the occurrence or development of vitiligo, must pay attention to.
