The dietary treatment of gastritis patients is a very crucial step. The general principle is that stimulating foods that are too acidic, too spicy and foods that are cold and indigestible should be avoided as much as possible. The diet should be chewed and swallowed slowly so that the food is fully mixed with saliva, which facilitates digestion and reduces the irritation of the stomach. Specifically, you can eat more mild types of vegetables, such as pumpkin, capers, leeks, beans, cabbage, cauliflower, etc., and more mild types of meat, fish, grass carp, silver carp, shrimp, dog meat, mutton, chicken, poultry eggs, etc. You can eat more mild fruits, such as apples, peaches, grapes, sugar cane, papaya, etc. In short, the diet should be regular and nutritious, eat more food containing vitamin A, vitamin B and vitamin C. Avoid taking strong tea and coffee, and be sure to quit smoking and alcohol.
