What are the dietary contraindications for stomach diseases?

       Gastric disease diet taboos are as follows: 1, be careful with cold, spicy, greasy, sticky and stimulating food Many patients with gastric disease due to the consumption of fried food, such as doughnuts, sesame, fried balls, etc., resulting in aggravation of the condition, and even gastric bleeding. Patients with gastric disease originally gastric mucosa is congested and edematous, if eat spicy and stimulating food will increase the secretion of gastric acid, more likely to cause damage to the gastric mucosa.  For raw and cold food, especially just from the refrigerator, freezer food has a strong stimulating effect on the digestive tract mucosa, after eating can lead to gastric spasm, gastric mucosal vasoconstriction, is not conducive to the inflammation of subside.  Sticky food, such as rice cakes, dumplings, lantern, etc., not easy to chew, not easy to digest, easy to stagnate in the stomach after eating, very easy to lead to indigestion, stomach pain, stomach blockage, do not want to eat and drink, etc.  Here, especially the issue of steamed bun pieces (or baked or fried), many people think that “steamed bun pieces nourish the stomach”, but in fact, steamed bun pieces dry and hard, more slag, chewing is not sufficient, will directly damage the esophagus or gastric mucosa, aggravating clinical symptoms.  2, try to eat less hard dried fruits peanuts, melon seeds and other dried fruits, such as chewing inadequate, these foods can directly stimulate the gastric mucosa to affect the effectiveness of treatment and recovery from the disease. Peanuts are rich in high-quality protein and fat and a variety of micronutrients, many patients with gastric disease by eating peanut rice to nourish the stomach, often counterproductive.  Some patients with gastric diseases, especially gastric ulcers, stomach acid patients, the reason why after eating raw peanuts, feel comfortable in the stomach, because raw peanuts in the stomach and gastric acid reaction, neutralized the acidic environment of the stomach, so that some symptoms have been improved.  In fact, this is the same effect as eating food such as cookies, to a certain extent, to reduce the stimulation of stomach acid. It should be reminded that some patients who eat raw peanuts may also aggravate gastric problems. Because when eating raw peanuts are not fully chewed, thus forming hard pieces of peanuts with angles into the stomach damage to the gastric mucosa, thereby aggravating the condition. In addition, there are some people are not suitable for eating peanuts.  In addition to people allergic to peanuts, enteritis, diarrhea, indigestion, cholecystitis and other diseases of patients are not often eat peanuts. Because peanuts are not only high in calories, high protein, or a high-fat food, too much peanuts will make the condition worse.  3, eat less smoked and pickled food According to the detection of smoked food contains 3,4-benzopyrene, which has the effect of gastric and respiratory cancer, and the longer the time of smoking, the higher the content, the stronger the carcinogenicity. Animal tests have also confirmed that high concentrations of salt combined with carcinogenic substances have significantly enhanced the carcinogenic effect on the stomach.  It has been found that the crude salt used for curing food contains nitrate and salt cured food contains nitrite, both of which can be transformed into nitrosamines under the action of bacteria, and the carcinogenic effect of nitrosamines has been confirmed. In recent years, some cities in China have widely adopted frozen food, which obviously reduces the intake of salt-pickled food and gradually decreases the incidence of stomach cancer.  Many people know that consuming too many beans will increase exhaustion, which is due to the fact that beans contain more oligosaccharides, which will produce a lot of gas after decomposition by intestinal bacteria, thus aggravating clinical symptoms such as gastric distension and burping.  In addition, beans contain more dietary fiber, these substances are not easily absorbed, easy to damage the gastric mucosa, and beans contain high purine, easy to stimulate gastric acid secretion, so people with excessive stomach acid should not eat. This shows that patients with stomach problems consume soy products or caution is better.  Of course, in life, each person’s reaction to food are specific, so the intake of food should be based on individual differences and appropriate adjustments, some food if you have eaten after feeling uncomfortable in the stomach, you can record, eat less or not in the future.  5, quit smoking, quit drinking, avoid drinking strong tea, coffee, carbonated beverages Smoking will cause bronchial disease, heart disease, liver disease and other diseases, but also inhibit the gastric mucosa synthesis of prostaglandins. Once the synthesis of prostaglandin is reduced, the protective factors of the gastric mucosa are also reduced, which will add difficulties to the repair of the gastric mucosa.  Cigarette contains nicotine, swallowed into the stomach, will stimulate the gastric mucosa, can cause submucosal vasoconstriction and spasm, resulting in gastric mucosa ischemia, lack of oxygen, thus playing a role in the destruction of the gastric mucosa.  Nicotine can also stimulate the vagus nerve, disrupting the normal gastrointestinal activity, which can lead to dysfunctional relaxation of the pyloric sphincter and contraction of the gallbladder, making it easy for bile to flow back into the stomach and damage the gastric mucosa.  Tobacco contains not only nicotine and other harmful substances, but also secondary amines, diethylamine and other amines. These substances can be synthesized in the body carcinogenic important substances, many kinds of cancer has a significant role in the induction. In addition, smoking can lower the immunity of human body, so smoking also has a more obvious role in triggering the occurrence of stomach cancer.  The harmful effects of alcohol on the stomach are well known. Long-term use of strong alcohol can directly damage the gastric mucosa, leading to the occurrence of gastric diseases and even bleeding. Alcohol can destroy both the normal physiological environment in the stomach, so that the protective effect of the gastric mucosa is weakened, but also cause the body’s whole body resistance to decline. The higher the concentration of alcohol, the greater the damage to the stomach. Continuous alcohol consumption is more harmful than intermittent alcohol consumption.  The gastric mucosa becomes thinner and the blood vessels are more sensitive to the stimulation of alcohol in patients with gastric disease. Also, alcohol is a good solvent for some carcinogens and can promote the absorption of certain carcinogens. Alcohol enters the body and can lead to the activation of certain carcinogens.  Long-term heavy alcohol consumption damages the gastric mucosa, which can lead to a lack of gastric acid, allowing bacteria to multiply and promoting the synthesis of carcinogens such as nitrosamines. In addition, alcohol will also inhibit the immune function of human body, causing a decrease in the supervision function of tumors. Therefore, patients with gastric disease should abstain from alcohol.  In addition, such as strong tea, coffee, carbonated beverages should also be avoided. Tea brewed too long, too thick, which tannic acid can directly stimulate the gastric mucosa, resulting in nausea, gastric distension. But for some tea drinkers, can drink a small amount of light tea.  People with a dry and hot body should drink cool tea, and those with a cold body should drink warm tea. Older people are generally suitable for black tea and pu-erh tea. Coffee contains caffeine will excessively promote the secretion of gastric juice, causing excessive secretion of gastric acid, prompting the gastric mucosa congestion, bringing bad effects to the stomach. When coffee comes in contact with air, it will oxidize and turn into unsaturated fatty acids, which can further aggravate the secretion of gastric acid.  Therefore, patients with stomach problems should not drink coffee. Especially people with stomach ulcers or heartburn symptoms should not drink drinks containing caffeine to avoid aggravating the condition. Carbonated beverages will foam as soon as they enter the stomach, giving the stomach wall a strong stimulus and prompting the secretion of gastric juice.  And carbonated beverages are often consumed on an empty stomach, because the secretion of gastric juice without food can be digested, will directly stimulate the stomach wall, more likely to lead to the onset of gastric disease, if there is an ulcer, it will make it further deteriorate.  6, not squatting to eat Some rural areas in China, especially in the northern countryside, many people have the habit of squatting to eat. Squatting to eat, the abdomen is squeezed, in addition to the gastrointestinal can not be normal peristalsis, but also make the gas in the gastrointestinal can not pass up and down, resulting in upper abdominal distension, but also prone to gastroesophageal reflux disease.  When eating, the peristaltic volume and tension of the stomach increases, requiring a large amount of blood, and squatting blood supply to the stomach is affected, it will directly weaken the digestive function of the stomach. Therefore, squatting to eat can lead to the occurrence or aggravation of gastric disease.
