Disease analysis: Hello, the epigastric pain of duodenal ulcer often occurs half an hour to an hour after eating, which is often related to the food eaten, such as white rice, corn flour and sweet potato, which can easily cause pain and pantothenic acid. Suggestions: In terms of food, due to excessive secretion of gastric juice, in order to protect the stomach wall, we should take more protein. Protein is rich in foods that do not irritate the stomach, such as tofu, white meat fish and milk. Beans also contain many excellent protein, but beans are not easy to digest, so they must be cooked until soft before eating. Peas are cooked lightly and softly, which can also strengthen the stomach and intestines. Vitamins are also indispensable to make the mucosa of the stomach strong, and you should eat more foods rich in vitamins such as fruits and vegetables. When cooking with oil, if you can make good use of olive oil or linseed oil, you can also inhibit gastric acid secretion; However, do not overdo it. What should be controlled are indigestible fish and shellfish such as shrimp and shellfish, fatty meat, fibrous vegetables such as bamboo shoots and sweet potatoes, and foods that are too sour and sweet. Vegetables should be boiled as soft as possible before eating.
