Certainly, corn can be eaten. Corn contains many trace elements, vitamins, and dietary fiber. When experiencing cheilitis, patients can appropriately eat some corn, which can also help facilitate bowel movements. Additionally, it is important for patients to pay attention to their diet by consuming easily digestible, nutritious foods. Opt for low-fat, low-salt, high-vitamin protein and high-fiber foods. Consuming more fungi, tuberous plants, or soy products to ensure adequate protein intake can be beneficial. Eating more fresh vegetables and fruits can also assist in the repair of cheilitis. Moreover, patients should avoid consuming raw, greasy, spicy, or irritating foods. When suffering from cheilitis, it is crucial to focus on reducing inflammation in the lips, and applying erythromycin ointment can be effective for anti-inflammatory treatment. (Note: The use of medications should be conducted under the guidance of a physician.)
