Doctors Warn: Avoid These Two Fruits If You Suffer from Mouth Ulcers and Diarrhea
While fruits rich in vitamin C can aid in healing, some can cause harm. Learn what to eat and what to avoid.
Many people have experienced the pain and discomfort of mouth ulcers, chapped lips, and burning sensations. Dr. Liu Boren, an expert in nutrition and functional medicine, shares valuable insights on what to eat and what to avoid when suffering from oral ulcers.
According to Dr. Liu Boren, it is recommended to avoid eating pineapple or kiwi if you have symptoms of oral ulcers. Although these fruits are rich in enzymes, dietary fiber, and vitamin C, they can cause serious damage to the mucosa, resulting in poor mucosal healing or intestinal permeability problems.
Nutritionist Cheng Hanyu advises paying attention to oral hygiene during oral inflammation, such as rinsing your mouth with salt water or non-alcoholic mouthwash. Avoid sprinkling salt on the wound to prevent excessive irritation or infection.
To repair wounds and relieve pain, eat foods rich in vitamin B complex, such as:
- Pork
- Oatmeal
- Eggs
- Milk
- Fish
- Chicken
- Red beans
- Avocado
- Salmon
- Bananas
- Scallops
- Broccoli
- Spinach
- Clams
- Mackerel

Additionally, supplement with vitamin C-rich foods like papaya and persimmon to speed healing and fight inflammation. Eat duck and beef blood to supplement iron, and oysters and shrimp to strengthen the immune system and repair mucous membranes.
Cheng Hanyu notes that a busted lip will typically appear swollen and painful for the first 2 to 3 hours, followed by a small white pit within 1 to 3 days. The pain will subside within 3 to 5 days, and the wound will heal within 2 weeks. If the wound does not heal within 2 weeks, it is essential to consult a dentist, oral surgeon, or ENT specialist for further evaluation and treatment.
