Foods to Avoid for the patients with Vitiligo

foods avoid for vitiligo patientsThere are many factors might induce vitiligo such as lack of tyrosinase, immune system disorder, so vitiligo patients need emphasize food therapy, increase the intake of copper, zinc, iron and other metal elements to increase the activity of tyrosinase and speed up the synthesis of melanin pigment. So what foods vitiligo patients should avoid?

1. Wines and seafood.

Vitiligo patients should avoid wines and seafood, there are many cases in the clinical showed the patients have vitiligo or worsen their vitiligo after over drinking or over eating seafood. The onset of vitiligo often happened after over eating seafood about one week. Some outpatients can clearly pointed out the causal relationship between the onset of vitiligo and over drinking or eating seafood, some patients complained there vitiligo will expand every time after they eat seafood and drink wines, part of vitiligo patients reflect that there vitiligo only feel itching after drinking wines. Some patients engaged in food service industry, work as a driver can not give up wines, the expand of their vitiligo are often hard to control. The mechanism and pathogenesis of over drinking can induce vitiligo can related with that the wine can influence the nerve endocrine, damage the liver, influence the absorption and synthesis of protein and zinc. As for over eating seafood might cause allergic reaction induce the immune system disorder. But there are few cases in clinical discover that eating mutton cause vitiligo.

2. Over intake vitamin C.

Vitiligo patients should avoid eating too much foods rich in vitamin C, because vitamin C is reducing agent, it participate in tyrosine metabolism, it can inhibit dopa, make the formatted melanin pigment in the skin reduced into colorless substances and make the melanin pigment changed into water soluble gelatinoid, in that way decrease the formation of melanin pigment. Vitamin C wildly exist in many fruits, vegetables and some leaves of the plants. The fruits rich in vitamin C includes melons, grapefruits, pawpaws, strawberries, citrus, watermelons, wild jujubes and so on. The fruit juices rich in vitamin C includes grapefruit juice, orange juice. Some fruit juices strengthen the vitamin C such as apple juice, sour fruit juice and grapefruit juice. The vegetables rich in vitamin C such as asparagus, cabbages, cauliflowers, leaf mustard, green chilies and red chilies, potatoes, sweet potatoes, tomatoes, tomato juice and so on. Generally speaking, the fruits and vegetables with sour flavor contains much vitamin C.

What we emphasize for vitiligo patients is to control the intake of foods contains too much vitamin C such as citrus, apples, tomatoes and so on, but in the collection of outpatient history, we rarely found there are case intake food vitamin C, there are more cases onset of vitiligo because of long term intake fruit flavor vitamin C or long term large dose orally take of inject vitamin C. There are a few hospitals or doctors prescribed medicines contains vitamin C for vitiligo patients and cause the localized vitiligo expanded into sporadic vitiligo.

3. Foods contains phenol.

There are many plant foods such as coffee, vegetables, fruits contains large amount of phenol, the phenol have cytotoxic effect to the melanin pigment.

4. Decrease the intake of the foods contains glutathione.

The symptoms of vitiligo is very obvious, the scientists in recent years discovered the long term lack of glutathione in the food can make the activity of tyrosinase in the skin increased, so except for the treatment of vitiligo symptoms, vitiligo patients also need to eat less or avoid eating foods rich in glutathione such as onion, garlic, tomato, fish, shrimp, mutton, chili and so on.

Eat less stimulating, pungent, spicy foods such as wines, chilies, garlic, mutton, fishes, shrimps and marine products, there are some fruits rich in vitamin C such as citrus, oranges, grapefruits, kiwifruits, tomatoes, hawthorns, waxberries and so on, they can eat more foods like peanuts, black sesame, black soya beans, walnuts, bean products, animal livers and so on, moreover, vitiligo patients should go to the specialized vitiligo hospital to treat their vitiligo to avoid delay their vitiligo.

Because vitiligo patients lack of some trace elements in their blood and vitiligo sites, it decreased their tyrosinase activity and influence the metabolism of melanin synthesis and finally cause the disease. So vitiligo should eat more foods rich in cooper, zinc, iron and other metal elements to increase the activity of tyrosinase and speed up the melanin synthesis.

Vitiligo patients should eat more foods rich in tyrosinase and mineral substances such as beef, rabbit meat, pig’s lean meat, animal livers, eggs, milk, fresh vegetables, beans like soy bean, pea, mung bean, bean products, peanuts, black sesame, walnuts, raisin, snail, clam and shellfishes. They need at the same time avoid intake chilies, wines no matter is beer or liquor, avoid eating tomatoes, because tomatoes rich in vitamin C. The vitamin C can stop the synthesis of melanin pigment and stop the melanin regeneration in the lesion areas. Other foods rich in vitamin C like citrus, grapefruits, apricot nuts, hawthorns, cherries, kiwifruits, strawberries, waxberries and so on should avoid or eat less.
