Gastric and duodenal ulcer disease is a common gastrointestinal disease, and the main reason for the formation of ulcers is the digestive juices secreted by the gastrointestinal tract, caused by the digestion of the mucosa itself, which can form ulcerated surfaces on the mucosa of the digestive tract. Rough physical irritation and chemical damage can aggravate the symptoms of ulcers, so it is important to avoid rough and irritating foods in the diet, and forbid the consumption of vegetables and fruits that contain a lot of coarse fiber, such as celery, leeks, apples, nuts, etc., as well as glutinous rice products that are difficult to digest. Spicy foods, such as chili peppers, strong-smelling condiments, alcohol, strong tea, coffee, etc., are not allowed.
