Dietotherapy is an important link in the prevention and treatment of ulcers. Patients should pay attention to the following points in diet: Strengthen nutrition, and choose foods that are easy to digest, contain enough calories, have protein and are rich in vitamins. Such as porridge, fine flour, milk, soft rice, soybean milk, eggs, lean meat, tofu and bean products; Foods rich in vitamins A, B and C, such as fresh vegetables and fruits. These foods can enhance the body's resistance, help repair damaged tissues and promote ulcer healing. Patients with more pantothenic acid should use less milk. To limit foods rich in residues, we should avoid eating fried foods and celery, leeks, bean sprouts, ham, bacon, dried fish and various coarse grains with more crude fiber. These foods are not only rough and difficult to digest, but also cause a large amount of gastric juice secretion, which increases the burden on the stomach. But digestible food, such as vegetable puree, can be eaten after processing. Do not eat foods that stimulate gastric acid secretion, such as broth, raw onions, raw garlic, concentrated juice, coffee, wine, strong tea, etc. And foods that are too sweet, too sour, too salty, too hot, and raw and cold. Sweet food can increase gastric acid secretion, stimulate ulcer surface and aggravate the condition; Overheated food stimulates the ulcer surface, causing pain, and even dilates the blood vessels on the ulcer surface, causing bleeding; Spicy food stimulates ulcer surface and increases gastric acid secretion; Too cold and hard food is not easy to digest, which will aggravate the condition. In addition, patients with ulcers should quit smoking. Nicotine in tobacco can change the pH value of gastric juice, disturb the normal activity of gastric pylorus, and induce or aggravate ulcer disease. Cooking should be done by steaming, roasting, frying and stewing. Fried, fried, smoked and other cooked vegetables are not easy to digest and stay in the stomach for a long time, which affects the healing of ulcer surface. Formulate a reasonable diet system, eat regularly and quantitatively, chew slowly, talk less, don't read books and newspapers, and don't watch TV; Let your mind relax and let your spirit slip away quickly. In the active period of ulcer, it is best to eat liquid or semi-liquid, digestible and nutritious food. In the past, some scholars formulated a system of eating less and eating more meals for patients with ulcers to avoid overeating or hunger. In recent years, it is believed that although eating can temporarily relieve pain, eating less and eating more meals constantly stimulates gastric acid secretion and makes gastric acid secretion active all day, which is obviously not conducive to the healing of ulcer disease. Therefore, in addition to acute attack complicated with bleeding and hematemesis, we should eat three meals a day regularly. Treatment of boiled eggs: 1 eggs, put them in a bowl, stir them evenly with chopsticks and use boiled water; It can be eaten after medium cooking. Modern medicine believes that boiled eggs are soft and easy to be digested and absorbed by the stomach, which can greatly reduce the burden on the stomach and is conducive to the healing of ulcer lesions. Egg yolk contains lecithin, which can form a thin hydrophobic layer on the surface of gastric mucosa, which has a strong protective effect on gastric mucosa and a defensive effect on the invasion of harmful factors. In order to avoid patients with dry stool, it is necessary to eat some foods that can moisten the intestines, such as agar, bananas, honey, etc., which is very important for patients with ulcers.
