How to improve gastrointestinal digestive function?

Suggestion: food digestion includes mechanical digestion and chemical digestion; The former refers to the movement of digestive tract, mechanically grinding food and mixing digestive juice to push food forward; The latter refers to the chemical decomposition of food by digestive enzymes in digestive juice. Pepsin in gastric juice can digest and decompose protein; Mucus can protect gastric mucosa; Gastric acid can denature protein, which is beneficial to protein's digestion. After gastric acid enters the small intestine, it can promote the secretion of pancreatic juice, bile and intestinal juice, which is beneficial to the digestion of food in the small intestine. The digestive juice of small intestine mainly includes pancreatic juice, bile and small intestine juice. Pancreatic juice contains amylase, lipase, protease, maltase, trypsin and other digestive enzymes. Although bile has no digestive enzymes, its bile salts are very important for the digestion and absorption of fat. Small intestinal juice contains many digestive enzymes, such as amylase, maltase, sucrase, lactase and lipase. Can decompose and digest sugar, fat, protein, etc. Whether gastrointestinal function is normal or not can directly affect the digestion and absorption of various nutrients in food. Bad eating habits will affect gastrointestinal function and produce various diseases. Foods that can promote digestion: 1. Barley and barley malt contain vitamins A, B, E, amylase, maltose, glucose, invertase, allantoin, protein decomposing enzyme, fat and minerals. Allantoin in barley can promote the healing of gastrointestinal ulcer. 2. Yogurt Yogurt contains all the nutrients of milk. Its outstanding feature is that it is rich in lactic acid, which can decompose lactose in milk into lactic acid. For patients who lack lactic acid enzyme in gastrointestinal tract or have diarrhea easily when drinking fresh milk, they can drink yogurt instead. Lactic acid can inhibit the growth of mold in the body and prevent the flora imbalance caused by antibiotics. Lactic acid can also prevent the accumulation of toxic substances produced by decomposing protein by spoilage bacteria, so it can prevent cancer. Yogurt has a laxative effect and can prevent constipation in the elderly. 3, the gastric juice secreted by milk milk is a weak irritant, with a weak alkaline reaction, can combine with gastric acid, neutralize gastric acid, and prevent gastric acid from stimulating the ulcer surface. 4, apples and apples can not only stop diarrhea, but also relieve constipation. Among them, acidic substances such as tannic acid and organic alkali have astringent effect, and the pectin contained can absorb toxins. For simple mild diarrhea, eating apples alone can stop diarrhea. The cellulose contained in apples can stimulate intestinal peristalsis and accelerate defecation, so it has a laxative effect. 5. Tomatoes are rich in organic acids such as malic acid, citric acid and formic acid, which can protect vitamin C from being destroyed during processing and cooking, and improve the utilization rate of vitamins. Tomatoes also contain a special ingredient-lycopene, which helps digestion and diuresis, and can help gastric juice digest fat. Lycopene can also inhibit the growth of bacteria and fungi and treat angular stomatitis. 6. The promoting effect of orange peel on digestion is mainly that it contains volatile oil that can stimulate digestive tract, increase gastric juice secretion and promote gastrointestinal peristalsis. 7. Chicken gizzard skin, also called chicken gizzard membrane, is the inner wall of chicken gizzard. Chicken gizzards contain gastric hormones and digestive enzymes, which can increase the secretion of gastric juice and gastric acid and promote gastric peristalsis. Stomach hormones are easily destroyed by high fever, so it is better to eat them raw. 8. Papaya Immature papaya contains two enzymes, one is papain and the other is papain, which can decompose fat into fatty acids and promote the digestion and absorption of food. 9. Cabbage contains a lot of crude fiber, which can promote gastrointestinal peristalsis, help digestion and prevent dry stool.
