There are some taboos and precautions in the diet therapy of vitiligo. Vitiligo should generally pay attention to the supplement of trace elements, such as copper and zinc, and eat more foods with high tyrosine, such as lean meat, pork liver and beef. It is suggested to eat more black food, such as black beans, black sesame seeds, nuts, walnuts, peanuts, etc., which is good for patients. Try to eat less spicy foods, such as hair, seafood, mutton, wine, etc., and eat less foods with particularly high vitamin C content, such as tomatoes and bayberry. In short, in the diet of vitiligo, patients are advised to eat more light and fresh food, eat more black food and eat less foods with high vitamin C content to ensure a balanced nutrition.
