Ancestral medicine believes that “the spleen and stomach are the origin of the postnatal period and the source of biochemistry of qi and blood”; “the large intestine is the official of transmission and change”, which illustrates the importance of gastrointestinal function in the human body. The basic physiological functions of the gastrointestinal tract are the intake, transfer and digestion of food, absorption of nutrients and excretion of waste, and the completion of these physiological functions depends on the coordinated physiological activities of the entire gastrointestinal tract. The motor function of the gastrointestinal tract turns the ingested food into fine crumbs and mixes them with digestive juices, pushing the crumbs forward and bringing them into full contact with the absorbing parts of the intestine, and completing defecation. The human gastrointestinal tract is like a machine that keeps working every day, and is the most tiring organ in the human body, and from the first mouthful of milk after birth, the gastrointestinal tract starts to work non-stop, and must digest, absorb, and excrete the dregs every day, and the nutrients needed for human growth and development depend on the gastrointestinal tract to digest and absorb food, and once the gastrointestinal tract is dysfunctional, the functions of other organs, tissues, and cells in the body will also be dysfunctional. Therefore, the gastrointestinal tract health care is essential for daily life. So how should we take care of our gastrointestinal tract? 1, life should be regular, work should be combined with work and rest, avoid overwork and mental tension. Because overexertion or long-term mental tension will lead to systemic neurohumoral regulation dysfunction, affecting the gastrointestinal tract motor function and the corresponding disease. 2, to develop good eating habits. ”Gastrointestinal diseases are caused by “wolf swallowing” and “food without time”, so you should chew and swallow slowly when eating, avoid swallowing rough food and eating too hot food, because rough food The food is rough, or eating too hot on the esophagus and gastric mucosa have a certain damage effect. Diet should be regular and quantitative, it is best to adhere to three meals a day, each meal 80% full, keep a good mood when eating, especially to remind the workforce, be sure to develop the habit of eating breakfast, spend the morning with an empty stomach busy work, often affect the normal physiological function of the gastrointestinal tract. It is best not to eat within two hours before going to bed at night, because eating before going to bed will lead to excessive secretion of stomach acid, and the resulting heat is easy to hoard, which is not beneficial to the gastrointestinal tract, to the human body. In addition, do not do strenuous exercise within half an hour before meals, and should not lie in bed immediately after eating during the day. 3, eat more fresh vegetables and fruits, eat more fiber-rich food, pay attention to keep bowel movements smooth. Fresh vegetables and fruits are rich in vitamins beneficial to the human body, which can prevent the occurrence of a variety of gastrointestinal diseases. Proper intake of dietary fiber can promote intestinal peristalsis, speed up the speed of defecation, and facilitate the timely elimination of harmful substances. In addition, in the process of metabolizing primary bile acids to secondary bile acids, crude fiber can also reduce the generation of nitrosamines and reduce carcinogenic factors. Experiments have shown that people who eat 35 grams of crude fiber per day have a 40% lower risk of colon and rectal cancer than those who eat 15 grams per day, and celery, shiitake mushrooms, corn, taro, sweet potatoes, brown rice, oats, dry beans and various vegetables and fruits are all rich in dietary fiber and should be added to the daily diet. In addition, attention should be paid to hydration, at least 5 to 6 glasses of water (about 1500 ml) a day, especially a glass of warm water in the morning to help cleanse the stomach and intestines, thus helping to guide the stool. Patients suffering from irritable bowel syndrome or chronic colitis should not eat dairy products, soy milk, soy milk and other gas-producing foods. 4, should quit smoking, limit alcohol. Smoking can increase gastric acid secretion, reduce duodenal bicarbonate secretion, affect the coordinated movement of the gastroduodenum, prompting an increase in mucosal damaging oxygen radicals, so smoking is one of the factors that cause peptic ulcers. In daily life, people are often accompanied by wine, as the saying goes, “no wine is not a banquet”, in order to improve the quality of the meal, people often invite guests to drink at the banquet. However, we should note that high concentrations of alcohol can directly damage the gastric mucosal barrier, so we should promote limited drinking. In particular, people suffering from esophageal, gastric and intestinal mucosal disorders should be prohibited from drinking, and avoid eating coffee, strong tea, carbonated beverages. 5, forbidden to eat moldy food, less salted vegetables, pickled and smoked food, avoid excessive intake of salt. Moldy food, pickled vegetables, pickled and smoked food, etc. contain nitrate. After long-term consumption of food with high whistle, nitrate is reduced to nitrite by bacteria in the stomach, and then combined with amine to produce carcinogenic nitrosamines, thus increasing the risk of esophageal cancer, stomach cancer and intestinal cancer. 6.Strengthen exercise and exercise gastrointestinal muscles. It can strengthen the peristalsis of the gastrointestinal tract and promote the secretion of digestive juices, thus enhancing the digestion and absorption function of the stomach and intestines. Every morning after waking up and insist on abdominal rubbing, deep abdominal breathing, anal contraction, sit-ups, etc., are the most simple and effective way to exercise the gastrointestinal muscles, promote the smooth muscle movement of the stomach and intestines, and enhance its tension. 7, do not abuse drugs. Many drugs have a stimulating effect on the gastrointestinal, long serving will damage the gastric mucosa, leading to erosive gastritis, hemorrhagic gastritis and the occurrence of ulcers. Antipyretic and analgesic drugs such as aspirin, pau taisong, anti-inflammatory pain, hormonal drugs such as prednisone, dexamethasone, antibacterial drugs such as erythromycin, cross-samycin, cold and flu medications such as cold and flu, day and night pepto-bismol, etc. have certain damaging effects on the gastric mucosa. Therefore, it is best to consult your doctor before taking these drugs, and to strictly follow medical advice and use them with caution. In short, with a healthy gastrointestinal tract, in order to have a healthy life, I hope we all have their own “way to maintain the stomach”!
