Gastritis should not eat too hard, too salty, overheated and spicy food. The most important thing in the diet is to try not to eat sweets, and not to eat hot and sour food, otherwise it may lead to aggravation of stomach inflammation. It is best not to eat snacks, barbecue and fried food. The three meals must be on time, especially breakfast, and dinner should not be too full or too late.
