Can people with gastritis eat oysters?

Patients with gastritis should avoid eating raw oysters, as oysters contain a high amount of protein that is easily digested and may exacerbate symptoms of gastritis. Oysters are also rich in minerals such as calcium and magnesium, which can stimulate gastric acid secretion upon entering the stomach, thereby worsening gastritis symptoms. Patients should choose light, nutritionally balanced foods and avoid spicy or irritating foods to prevent aggravating their condition.
