Can patients with keratitis eat wood ear fungus?
Keratitis refers to inflammation of the cornea—the outermost layer of the eye—which is particularly susceptible to injury and infection due to its direct exposure to the external environment. Trauma may occur accidentally. In mild cases, keratitis typically presents with photophobia (sensitivity to light) and epiphora (excessive tearing). Severe cases may lead to blindness. So, can patients with keratitis consume wood ear fungus (Auricularia auricula-judae)?
Can Patients with Keratitis Consume Wood Ear Fungus?
Yes, patients with keratitis may consume wood ear fungus. Their diet should include a balanced combination of meats and vegetables, with an emphasis on high-protein foods—such as oats, pork heart, dried tofu skin, and peanuts. Intake of spicy foods (e.g., chili peppers, raw garlic) should be minimized. Fried meats, fatty meats, and sweets should also be limited. Reducing consumption of simple sugars and high-calorie grilled foods is advisable. Dietary fiber in black wood ear fungus promotes gastrointestinal motility. Moreover, it contains bioactive compounds with antitumor properties, which help enhance immune function and support cancer prevention.

Patients with keratitis should avoid spicy and cold foods. If the condition is allergic in origin (i.e., allergic keratitis), it is crucial to avoid common allergenic foods—such as seafood (fish, shrimp, shellfish). Similarly, foods containing heterologous proteins (e.g., cicadas) should be avoided. It is also important to limit intake of foods containing excessive preservatives or artificial colorants. Instead, patients are encouraged to consume more protein-rich foods—such as lean meat, eggs, and milk—as well as fresh fruits and vegetables rich in vitamins, including oranges, kiwifruit, and pineapple.

Therefore, patients should consistently practice good ocular hygiene, avoid eye strain, and maintain a diet rich in fresh fruits and vegetables. We hope this information proves helpful.
