What Foods Should Be Avoided in Solar Dermatitis?

Solar dermatitis (also known as sun-induced dermatitis) results from 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 manifesting as patchy or plaque-like lesions that appear yellowish-brown or brown in color. So, what foods should individuals with solar dermatitis avoid? The specifics are as follows:

Patients with solar dermatitis should avoid the following vegetables: ginger, cilantro (coriander), turnip greens, toon sprouts, and hot peppers. Instead, they are encouraged to consume other vegetables. They should also avoid strong spices and condiments—including star anise, Sichuan peppercorns, black pepper, fennel seeds, cinnamon bark, mustard, mustard oil, chili sauce, hotpot seasonings, and instant noodle flavoring packets. All types of 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 ready-to-eat meat products should also be avoided.

Topically, patients may apply calamine lotion or topical corticosteroid creams. For severe symptoms, oral cetirizine may be prescribed. Cold compresses can effectively reduce cutaneous allergic reactions and help alleviate solar dermatitis. Dietarily, patients should focus on light, mild foods—such as Chinese cabbage, potatoes, radishes, and Chinese yam—and may also consume fruits like apples and pears.
