We often warn patients with gastric diseases (including chronic superficial gastritis, bile reflux, atrophic gastritis, ulcer disease, gastric tumor patients), the following “five vajra” do not eat: cigarettes, old wine, strong tea, coffee, milk. Some patients do not understand: everyone says milk is good for the stomach, why do you say not to drink or drink less. Our clinical experience tells us that many patients drink milk to increase stomach fullness and flatulence, so we recommend drinking more yogurt or almond milk, and yogurt is also good for intestinal probiotics. The following are the more detailed topics elaborated in classic textbooks, which can be referred to appropriate control: 1, you should quit smoking, alcohol, coffee, strong tea, carbonated drinks (soda), sour and spicy and other irritating foods: the most damaging to the stomach. 2, eat less fried food: not easy to digest. 3, eat less pickled food: more salt and certain carcinogens, should not eat more. 4, eat less cold food: strong stimulating effect on the mucosa of the digestive tract, easy to cause diarrhea or inflammation of the digestive tract.
