Vitiligo is a stubborn skin disease. Patients need to pay attention to many things in their daily life, and diet is a very important factor. 1: Prevent taking vitamin C, and eat less or no fruits and vegetables rich in vitamin C. Cheng Aihua said that it is not advisable to eat too much food rich in vitamin C, because vitamin C will hinder the synthesis of melanin, thus affecting the recovery effect. Such as green pepper, tomato, citrus, grapefruit and so on. Because vitamin C will hinder the formation of melanin in the body, so eat less. 2, eat more foods rich in copper, if the copper ion content in the body increases, the natural growth of melanin will also increase. Therefore, we should eat more foods containing copper, such as snails, mussels and clams. 3. Auricularia auricula, kelp, sea cucumber, celery, eggplant, Toona sinensis, walnut kernel, tuanyu, amaranth, leek, Nostoc flagelliforme, black rice, elm leaves, etc. all have the effect of preventing vitiligo, and can be eaten frequently. Do not eat strawberries, bayberry, hot and sour food and hair products such as chicken and sheep. 4. Vitiligo patients should usually eat more foods containing tyrosine and minerals, such as meat (beef, rabbit meat, lean pork), plant liver, eggs (eggs, duck eggs, quail eggs), milk (milk, yogurt), novel vegetables (radish, eggplant, kelp, etc. ), beans (soybeans, peas, mung beans and bean products), peanuts and bean products.
