What should patients with vitiligo pay attention to in their diet?

Patients with vitiligo should avoid consuming spicy and irritating foods, raw or cold-natured foods, seafood, and similar items. Specific details are as follows:

1. Spicy and Irritating Foods

Vitiligo is typically caused by primary skin depigmentation leading to white patches. It may cause immune dysfunction and damage melanocytes to some extent. In daily life, dietary adjustments are important; patients should try to avoid spicy and irritating foods such as chili peppers, garlic, and onions, which may trigger adverse skin reactions.

2. Raw, Cold, and Chilled Foods

During active stages of vitiligo, gastrointestinal function may decline. Consuming raw, cold, or chilled foods—such as ice cream or cold jelly noodles—may damage the gastrointestinal mucosa, impair digestion, and worsen stomach discomfort.

3. Seafood

Consuming seafood may increase the risk of allergic inflammation, causing symptoms such as redness, swelling, and itching of the skin. It may also lead to a burning sensation or peeling, thereby increasing skin irritation.

In addition to the above, patients should also limit intake of fruits high in vitamin C. Individuals with vitiligo can, under a doctor's guidance, use medications such as vitiligo capsules or vitiligo pills for treatment. They should also take sun protection measures, such as wearing hats and using umbrellas when going outdoors, to avoid prolonged exposure to ultraviolet radiation.
