In daily life, we should eat less spicy food such as wine, pepper, raw garlic, mutton, fish and shrimp, and eat less fruits rich in vitamin C such as oranges, oranges, grapefruit, kiwi fruit, tomatoes, hawthorn and bayberry. We should usually eat more foods containing tyrosine and minerals: meat (beef, rabbit meat and lean pork), animal liver and eggs (eggs, duck eggs and quail). Due to the lack of some trace metal elements in blood and leukoplakia, the tyrosinase activity in vitiligo patients decreases, which affects the synthesis and metabolism of melanin, resulting in lesions. Therefore, patients should eat more foods containing copper, zinc, iron and other metal elements to enhance tyrosinase activity and accelerate melanin synthesis.
