The site and symptoms of gastric and duodenal ulcers are different, but the principles of dietary treatment are the same, and the ultimate goal is to promote ulcer healing and prevent recurrence. (a) Small amount and multiple meals at regular intervals. 5-7 meals per day, the amount of each meal should not be more. A small number of meals can neutralize gastric acid, reduce the stimulation of gastric acid on the ulcer surface, and can supply nutrition, which is conducive to the healing of the ulcer surface, more suitable for acute peptic ulcer. (B) avoid irritating food. Mechanical and chemical stimulation of strong food should be avoided, mechanical stimulation increases damage to the mucosa, destroy the mucosal barrier, such as coarse grains, celery, leeks, snow, bamboo shoots and dried fruits, etc.. Chemical stimulation will increase the secretion of gastric acid, which is detrimental to ulcer healing, such as coffee, strong tea, strong wine, strong broth, etc. Avoid acid-producing foods, such as groundnuts, potatoes, overly sweet snacks and sweet and sour foods; gas-producing foods, such as raw onion, raw garlic, raw radish, garlic, onion, etc.; raw and cold foods, such as a lot of cold drinks, cold dishes, etc.; hard foods, such as bacon, ham, sausage, mussels, etc.; strong condiments, such as pepper, curry powder, mustard, chili oil, etc. (C) choose fine and soft easy to digest food. Choose foods with high nutritional value, fine and soft and easy to digest, such as milk, eggs, soy milk, fish, lean meat, etc. After processing and cooking to make it soft and easy to digest, no stimulation to the stomach and intestines. Also supplement with sufficient calories, proteins and vitamins. Nutrient ratio semi-liquid period for carbohydrate 55%, protein 15%, fat 30%; fluid period for carbohydrate 60%, protein 20%, fat 20%. 1, protein: protein plays a buffering role for gastric acid, can neutralize gastric acid, but protein digestion in the stomach and can promote gastric acid secretion. Should supply enough protein to maintain the body’s needs, according to 1g/kg per day to promote ulcer repair; if anemia, at least 1.5g/kg. 2, fat unlimited: no need to strictly limit fat, because it can inhibit gastric acid secretion. A moderate amount of fat does not stimulate the gastrointestinal mucosa, but too high can promote increased secretion of cholecystokinin and inhibit gastrointestinal peristalsis; food in the stomach does not easily enter the duodenum, causing gastric distension and pain. Can supply 70 to 90g/d, should choose easy to digest and absorb cheese-like fat, such as milk, cream, egg yolk, cheese, etc., and the right amount of vegetable oil. 3, more carbohydrates: neither stimulate gastric acid secretion effect, nor inhibit gastric acid secretion, can supply 300 ~ 350g per day. choose easy to digest food, such as thick porridge, noodles, ravioli, etc.. Cane sugar should not be too much, because it can increase gastric acid secretion, and easy to flatulence. (D) supply rich vitamins. Choose foods rich in B vitamins, vitamin A and vitamin C; staple food is mainly pasta, fasting should be fasted when bleeding, blood stop eating liquid diet. (E) cooking methods ulcer disease eat food must be chopped and cooked. Can choose to steam, boil, boil, soft boil, braise, stew and other cooking methods, should not use oil frying, deep-frying, stir-fry, vinegar, cold and other methods of food processing. (F) other. When eating should be relaxed, chew and swallow slowly, to facilitate digestion. Take care of the patient’s eating habits and prepare delicious meals. Provide fine, soft, coarse fiber less food, should pay attention to prevent constipation. Extra meals before bedtime are particularly suitable for duodenal ulcers, which can reduce hunger pain and facilitate sleep.
