Medical experts have found that the occurrence of stomach cancer is closely related to four factors, which are overweight, smoking, acid reflux and eating too few fruits and vegetables. Therefore, it is necessary to develop good habits to prevent stomach cancer. Some people like to mix rice and soup together and eat soup with rice, which will make the food slide into the stomach before chewing in the mouth and increase the burden of gastrointestinal tract. In addition, eating soup soaked rice will also make saliva secretion less, which is not conducive to food digestion, nutrition can not be fully absorbed. In addition, the taste nerve is not properly stimulated, the gastrointestinal tract digestive juices secretion is reduced, which will eventually lead to gastrointestinal dysfunction, digestion and malnutrition. Appropriate spicy food can add to health, however, excessive spicy food can cause excessive secretion of digestive juices, causing congestion of gastrointestinal mucosa, edema, and a sharp increase in peristalsis. Deep-fried food is not easy to chew very finely and mix very evenly because of its hard texture, which will affect its digestion in the stomach and small intestine. After the food is fried, most of the particles are wrapped in grease, reducing the opportunity to contact with protein or starch, so it is more difficult to digest, will increase the burden on the stomach and intestines, prone to acid reflux, nausea and other discomfort. Expert advice: soup bubble rice is not suitable for long-term eating, occasionally eat once to do chew slowly, so as to reduce the gastrointestinal burden. In addition, it is best to change the habit of eating soup bubble rice to soup or thin rice before meals. Drinking a small amount of soup before meals not only moistens the mouth and esophagus, but also stimulates the mouth and stomach to produce saliva and gastric juice, which helps digestion. After a period of boiling, the rice becomes soft and the starch breaks down into dextrin that is easily absorbed by the stomach and intestines, which will not affect digestion. For people who like spicy food, drink a glass of milk before eating spicy food to protect the stomach mucosa. For people with poor gastrointestinal or body heat, if you really can not refuse the temptation of spicy food, you can choose some slightly spicy food. 2, fasting to eat acidic fruit easy stomach bloating people in fasting, the concentration of gastric acid is high, at this time if you eat a lot of acidic fruit, will make the combination of gastric acid and fruit ingredients, the formation of insoluble precipitates. Once the precipitates form a large lump, it will make the pressure in the stomach rise, causing bloating and pain, producing a series of uncomfortable reactions and digestive tract diseases such as gastric distension and acidity. For example, persimmons contain persimmon gum, pectin, ellagic acid and ellagitannin, which can cause “stomach persimmon stone disease” when eaten on an empty stomach. Hawthorn taste sour, can move the gas and eliminate food, but eat too much on an empty stomach, the stomach is more hungry, and can aggravate stomach problems. Expert advice: patients with gastric and duodenal ulcers and excessive stomach acid should not eat hawthorn, lemon, prunes, plums and other highly acidic fruits to avoid increasing gastric acid secretion, stimulating the gastric mucosa and affecting ulcer healing. 3, smoking, drinking strong alcohol, unclean diet, drug stimulation trigger gastric ulcer Smokers think that nicotine will only enter the lungs, but do not know that the smoke will also enter the stomach with the digestive tract, directly stimulate the gastric mucosa, causing submucosal vasoconstriction, spasm, gastric mucosa ischemia, hypoxia symptoms, in the long run, it is easy to form a stomach ulcer. Moderate consumption of low alcohol can increase the blood flow of the stomach blood, but long-term or a large amount of strong alcohol at one time will directly destroy the gastric mucosal barrier, causing congestion, edema, erosion, and even bleeding. Helicobacter pylori is an important culprit in causing gastric ulcers, and infection with this germ is mostly due to unclean diet and mutual transmission. Many drugs, such as antipyretic and anti-inflammatory (aspirin, paracetamol, painkillers), adrenal glucocorticoids (dexamethasone, cortisone) can directly or indirectly damage the gastric mucosa, increasing gastric acid and pepsin secretion, causing inflammation and ulcers, and in critical cases, gastric bleeding and perforation. Expert advice: drink moderate amounts of rice wine, wine and other low alcohol, avoid drinking large amounts of white wine, do not drink poor quality wine. Before drinking, eat in moderation to reduce the direct stimulation of alcohol on the gastrointestinal tract. Meal sharing can reduce the chances of contracting H. pylori. Especially when someone in the family suffers from gastric ulcer, meal sharing system is very necessary. Never take drugs indiscriminately, long-term use of drugs that stimulate the stomach, it is best to take some gastric mucosa protective drugs. 4, walk and eat, look and eat indigestion In order to save time, many people’s breakfast is solved on the way to work, and Chinese food and often to books, computer screens while eating, which will make the stomach very uncomfortable. Digestion” is a stressful and heavy work, need a lot of adequate blood, if the body is in motion at this time, will greatly divert the gastrointestinal tract “power supply”, will certainly affect its normal digestive function, eventually leading to gastritis, and even gastric prolapse. Similarly, eating while watching makes the brain and intestines invariably “compete” for blood, which can also cause indigestion. Expert advice: get up 15-20 minutes early every day, half an hour after waking up to sit down quietly to eat breakfast. When eating, focus on the food, chew slowly, enjoy the food, so that the stomach most like to eat. 5.Three irregular meals, excessive stress, like to eat smoky food and eat too hot can cause cancer. A survey shows that the risk of stomach cancer for those who often have three irregular meals is 1.3 times of normal people, 1.5 times for angry eating and 4.22 times for like to eat hot food. If the above factors work together, the relative risk of stomach cancer is higher. Zhang Ye said that stomach is an organ that is used to following a “schedule”, and there are physiological peaks and valleys in the secretion of gastric juice throughout the day to facilitate timely digestion of food. Stomach acid and pepsin will digest the gastric mucosa itself if there is no food to neutralize it, causing damage to the gastric mucosa. Hungry meal, full meal, often do not eat breakfast, sometimes overeating, coupled with night driving, irregular life, so that the development of stomach cancer has a “good” soil. Cured meat, smoked fish and other processed meat products contain a large amount of nitrite, which can easily form nitrosamides and directly induce tumors in the stomach, which is also the reason for the high incidence of stomach cancer in coastal areas and the high incidence of stomach cancer in Japan. Swedish scientists found that every 30 grams increase in the daily intake of processed meat products, the chance of stomach cancer increases by 15%-38%. In addition, the human digestive tract mucosa is very delicate, can only tolerate 50-60 ℃ food, more than this temperature, the mucosa will be scalded. Like just steeped tea, the temperature can reach 80-90 ℃, it is easy to scald the digestive tract. If you often eat food that is too hot, the mucosal damage is not yet repaired and scalded again, repeatedly scalding and repairing will cause changes in the quality of the mucosa and further develop into cancer. Expert advice: for people who cannot eat on time, they should always have some soda crackers, instant oats and other snacks around them, and they should fill their stomachs with something to fight stomach acid and not let their stomachs “idle”. But this method can only be used as an occasional response, if you do this for a long time, the same damage to the stomach. People who like smoked food should reduce the frequency of consumption and try it occasionally. Pay attention to the smoked food should not be in direct contact with the fire, do not smoke too long, do not eat the baked part at all, because such proteins have been denatured. In addition, eat barbecue at the same time, to eat more vegetables and fruits rich in vitamin C, can also play a role in fighting carcinogens.
