What Foods Should Be Avoided in Solar Dermatitis?

Solar dermatitis—also known as sun-induced dermatitis—occurs due to excessive sun exposure, which triggers increased melanin production in the deeper layers of the skin. This excess melanin gradually accumulates on the skin surface, typically appearing as patchy or plaque-like lesions with yellowish-brown or brown discoloration. So, what foods should individuals with solar dermatitis avoid? Details are listed below:

Patients with solar dermatitis should avoid the following vegetables: ginger, cilantro (coriander), turnip greens, toon sprouts, and chili peppers. Instead, they are encouraged to consume other vegetables. They should also avoid strong spices and seasonings—including star anise, Sichuan pepper, black pepper, fennel, cinnamon, mustard, mustard oil, chili sauce, hotpot seasonings, and instant noodle flavoring packets. All alcoholic beverages—including baijiu (Chinese distilled spirit), beer, and wine—should be strictly avoided.

Regarding meats, patients should avoid beef, wolf meat, donkey meat, camel meat, mutton, dog meat, chicken, duck, pigeon, bird meat, and their broths, as well as all types of seafood—including fish, crab, and shrimp. Recommended protein sources include lean pork, eggs, and milk. Processed pork trotters and other pre-cooked meat products should also be avoided.

Topical treatment options for solar dermatitis include calamine lotion or topical corticosteroid creams. In cases of severe symptoms, oral cetirizine may be prescribed. Cold compresses can effectively reduce cutaneous allergic reactions and help alleviate symptoms of solar dermatitis. Diet should emphasize light, bland foods—such as Chinese cabbage, potatoes, radishes, and Chinese yam—as well as fruits like apples and pears.
