Can patients with oral ulcers eat seafood?

Generally, whether patients with oral ulcers can eat seafood depends on the severity of the ulcer and individual physical condition. If discomfort occurs or symptoms worsen, medical advice should be sought promptly. Detailed analysis is as follows:

If oral ulcers are mild, with only small localized lesions, and the individual has no allergy to seafood, a small amount may be consumed. Opt for gently cooked seafood such as steamed or boiled preparations, which preserve nutrients, have a soft texture, minimize mechanical irritation to the ulcerated area, and provide high-quality protein and trace elements that support mucosal healing. However, intake should be controlled to avoid excessive consumption.

If oral ulcers are severe, with large lesions and intense pain, or if the individual has an allergic constitution or known seafood allergy, seafood should be avoided. Certain components in seafood may trigger allergic reactions and exacerbate inflammation. Additionally, seafood prepared with spicy stir-frying or deep-frying methods is highly irritating and can directly aggravate the ulcer, increase pain, and delay healing.

When consuming seafood, ensure freshness, as spoiled seafood may harbor bacteria that cause gastrointestinal discomfort or worsen systemic inflammation. It is also important to pair seafood with light vegetables and staple foods to maintain dietary balance, avoid concurrent intake of spicy or excessively hot foods, and rinse the mouth promptly after eating to reduce food residue and its impact on the ulcer.
