What fruits can patients with oral ulcers eat?

Generally, patients with oral ulcers can eat fruits such as apples, pears, bananas, kiwifruits, and watermelons. These fruits help provide essential nutrients, reduce oral irritation, and promote ulcer healing. Here is a detailed analysis:

1. Apples: Apples are neutral in nature and have a relatively soft texture, rich in vitamin C and dietary fiber. They cause minimal friction against ulcerated areas, and the vitamin C helps promote mucosal repair, alleviating pain and discomfort caused by ulcers.

2. Pears: Pears are cooling in nature and high in water content, containing various vitamins and minerals. Their soft texture does not irritate ulcers, while their moisturizing properties help hydrate the mouth, relieve dryness and pain associated with ulcers, making them suitable for consumption during an ulcer episode.

3. Bananas: Bananas have a soft, creamy texture and are rich in B-complex vitamins and potassium. The B vitamins help maintain healthy oral mucosa, and the soft consistency requires little chewing, minimizing contact with ulcer sites and reducing pain—making bananas ideal to eat during ulcer flare-ups.

4. Kiwifruits: Kiwifruits are rich in vitamin C and various trace elements, with particularly high levels of vitamin C that promote collagen synthesis, aiding in the repair of damaged oral mucosa and accelerating ulcer healing. However, it's important to choose fully ripe kiwifruits to avoid excessive acidity that might irritate the ulcers.

5. Watermelons: Watermelons have extremely high water content and a cooling nature, which can quickly replenish oral moisture and relieve dryness and burning sensations caused by ulcers. The soft flesh does not rub against ulcerated areas, and the hydration boost supports metabolism and aids in recovery.

In daily life, in addition to obtaining nutrients from fruits, it's important to maintain good oral hygiene—rinsing the mouth with warm water after meals and avoiding spicy or excessively hot foods. Additionally, maintaining regular sleep patterns and avoiding late nights can reduce the likelihood of ulcer recurrence and support faster recovery of oral health.
