Digestion of food includes two aspects: mechanical digestion and chemical digestion; the former refers to the movement of the digestive tract, mechanical grinding of food and mixing of digestive juices to push the food forward; the latter refers to the movement of digestive juices The digestive enzymes in the food chemically break down the food. Pepsin in gastric juice can digest and decompose proteins; mucus can protect the gastric mucosa; gastric acid can denature proteins, which is beneficial to protein 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 movement of food in the small intestine of digestion. The digestive juices of the small intestine mainly include pancreatic juice, bile and small intestinal juice. Pancreatic juice contains a variety of digestive enzymes such as amylase, lipase, protease, maltase and trypeptidase. Although bile does not have digestive enzymes, its bile salts are important for the digestion and absorption of fat. Small intestinal juice contains a variety of digestive enzymes, such as amylase, maltase, sucrase, lactase, lipase, etc. Can break down and digest sugar, fat, protein, etc. Whether the gastrointestinal function is normal can directly affect the digestion and absorption of various nutrients in food. Bad eating habits can affect gastrointestinal function and cause various diseases.
Foods that promote digestion:
1. Barley and barley malt contain vitamins A, B, E, amylase, maltose, glucose, invertase, allantoin, and protein. Break down enzymes, fats and minerals, etc. Allantoin in barley promotes the healing of gastrointestinal ulcers.
2. Kefir. In addition to containing all the nutrients of milk, kefir's outstanding feature is that it is rich in lactic acid, which can decompose the lactose in the milk into lactic acid. For patients who lack lactase in the gastrointestinal tract or who are prone to diarrhea when drinking fresh milk, they can drink yogurt instead. Lactic acid can inhibit the growth of mold in the body and prevent bacterial imbalance caused by the use of antibiotics. Lactic acid can also prevent the accumulation of poisons produced by putrefactive bacteria from decomposing proteins, so it has an anti-cancer effect. Yogurt has a laxative effect and can prevent constipation in the elderly.
3. Milk Milk is a weak irritant to the secretion of gastric juice and has a weak alkaline reaction. It can combine with gastric acid, neutralize gastric acid, and prevent gastric acid from irritating the ulcer surface.
4. Apples Apples can both stop diarrhea and relieve constipation. It contains tannic acid, organic bases and other acids that have astringent effects, and the pectin contained in it can absorb toxins. For simple mild diarrhea, eating apples alone can stop diarrhea. The fiber contained in apples can stimulate intestinal peristalsis and accelerate defecation, so it also 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 cooking and increase the utilization of vitamins. Tomatoes also contain a special ingredient - tomato, which helps digestion, diuresis, and helps gastric juice digest fat. Tomato can also inhibit the growth of bacteria and fungi, and can treat angular stomatitis.
6. Orange peel: The main role of orange peel in promoting digestion is that it contains volatile oils that stimulate the digestive tract, increase the secretion of gastric juice, and promote gastrointestinal motility.
7. Chicken gizzard skin, also known as chicken gizzard skin, 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. Gastric hormones are easily destroyed when exposed to high heat, so it is better to eat them raw.
8. Papaya Immature papaya contains two enzymes, one is called papain and the other is papaya protease, which can break down fat into fatty acids and promote the digestion and absorption of food. .
9. Cabbage contains a large amount of crude fiber, which can promote gastrointestinal motility, help digestion, and prevent dry stools.
