What Foods Should Be Avoided in Solar Dermatitis?

Solar dermatitis—also known as sunburn 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 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 chili 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, cassia bark, mustard, mustard oil, chili sauce, hotpot seasonings, and instant noodle flavor packets. All alcoholic beverages—including baijiu (Chinese distilled spirits), beer, and wine—should be strictly avoided.

Additionally, patients should avoid meats such as beef, wolf meat, donkey meat, camel meat, mutton, dog meat, chicken, duck, pigeon, and bird meat—as well as broths made from these meats—and 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 solar dermatitis. Dietarily, patients should focus on light, bland foods—such as Chinese cabbage, potatoes, radishes, and Chinese yam—and may also consume fruits like apples and pears.
