For patients with chronic gastritis, we recommend avoiding irritant foods and opting for foods that cause less irritation to the stomach. Avoid overly acidic or sweet foods. It is suggested that patients keep foods like steamed buns and soda crackers, which are alkaline, on hand. Try to avoid consumption of raw, cold, hard, or hot foods, as well as tea, coffee, and substances like tobacco and alcohol, which are highly irritating to the stomach.
