Ulcer disease patients in the diet should pay attention to matters: 1, develop a reasonable diet: regular life, avoid staying up late, reduce unnecessary worries, keep a happy mood, do not eat 2-3 hours before bedtime, avoid too tight clothes. Eating should be regular and quantitative, chew and swallow slowly. In the ulcer activity period, to eat liquid or semi-liquid, easy to digest, nutritious food, and a small number of meals is appropriate, after the symptoms are controlled, should resume the usual three meals a day regular diet, and should avoid snacking between meals. 2, strengthen nutrition: should be easy to digest, contains enough heat, protein and vitamin-rich food such as thin rice, thin noodles, soft rice, soy milk, eggs, lean meat, tofu and soy products; contains a very large amount of vitamin A, B, C food, such as fresh vegetables and fruits, etc.. These foods can increase muscle resistance, help repair damaged tissues and enhance ulcer healing. Patients with heavy acid reflux and in the acute stage should drink as little soy milk and milk as possible, as they can stimulate excessive secretion of gastric acid. 3, avoid eating rough and irritating food: avoiding mechanical, chemical and cold stimulation of food is beneficial to protect the gastric mucosa. Mechanical stimulation can increase the damage to the gastric mucosa and destroy the barrier role of the gastric mucosa. Therefore, (1) avoid eating raw and cold vegetables, fruits, coarse fiber foods, such as coarse grains, celery, leeks, snow vegetables, bamboo shoots, dried fruits, dried beans, etc.; (2) avoid eating foods that are easy to produce gas, such as raw onion, raw garlic, raw radish, garlic, onion; (3) foods that are easy to produce acid, such as groundnuts, cold noodles, potatoes; (4) avoid eating too sweet snacks and sugar and vinegar food, etc.; (5) avoid eating a lot of cold drinks, spicy cold dishes (5) Avoid eating a lot of cold drinks, spicy and cold dishes, hard and indigestible foods, such as bacon, ham, sausages, mussels, fried foods, rice cakes, glutinous rice products such as dumplings, etc.; all the above foods can aggravate the condition of ulcer disease and promote the recurrence of ulcer disease. However, a variety of coarse grains processed into vegetable puree and other easily digestible food can be consumed. (6) Chemical stimuli have a strong excitatory and irritating secretion of gastric juice, such as thick broth, gravy, coffee, cola, MSG, chocolate and carbonated drinks such as Sprite; and strong condiments, such as mustard, pepper, wine, chili, chili oil, vinegar and curry; as well as fried and deep-fried foods and large amounts of sucrose, etc. (7) Any food that is too cold or too hot can stimulate the ulcer surface, so it should be avoided, and the general temperature of food should be 45℃. In short, the food should not be too acidic, too sweet or too salty, to light and refreshing, not greasy and fatty. So in addition to this, what else needs attention? 1, quit smoking and alcohol: Nicotine in tobacco can change the pH of the gastric juice, disrupting the normal activities of the gastric pylorus, triggering or aggravating ulcer disease. Ethanol can directly destroy the protective layer of the gastric mucosa, resulting in the formation of gastric mucosal erosion ulcer. So ulcer patients should quit smoking and quit drinking. 2, food preparation methods: ulcer disease eat food must be chopped and cooked; cooking to appropriate to steam, stir-fry, burn and stew method is better. Pan-fried, smoked, fried and other cooking dishes are not easy to digest and stay longer in the stomach, affecting the healing of the ulcer surface. 3, avoid taking drugs that damage the gastric mucosa: dexamethasone, prednisone, anti-inflammatory pain, some drugs such as aspirin have an irritating effect on the gastric mucosa, which can aggravate the condition of gastric ulcers, should be avoided as much as possible.
