Old fire soup, boat porridge, soup and porridge occupy an important position in the Guangzhou people's diet. Many people in Guangzhou drink soup and porridge like hot drinks. When drinking white porridge, many “Lao Guang†also like to pick salted pickles like dried radish, but these foods have high levels of nitrosamines, and nitrosamines are a relatively strong carcinogen. It is these bad eating habits that cause mechanical damage to the stomach and increase the risk of stomach cancer. In addition, Guangzhou people sigh for morning tea and afternoon tea, including the habit of drinking tea after pre-dinner meals. If the tea is still hot, it will increase the risk of stomach cancer.
Eat pickles and fish sauce easily induce gastric cancer
Now people's living conditions are good, but many bad eating habits are still difficult to change, such as heavy taste, love to eat pickled foods. South China is accustomed to marinating seafood, and it is particularly popular with fish sauce, shrimp paste and other condiments. It is a well-known high-risk area for gastric cancer in the country. In addition, Zhuanghe City in Liaoning Province, Linyi County in Shandong Province, Zanhuang County in Hebei Province and other residents have a dietary habit --- long-term consumption of salted pork.
What are the early symptoms of gastric cancer? Experts remind that pickled foods will directly injure the gastric mucosa because of more salt, and the nitrites contained therein will turn into nitrosamines under the action of stomach acid and bacteria, which is more likely to cause gastric cancer.
Do not love to use chopsticks to prevent bacteria
"Never clean up, eat no illness" is the mantra of many old people. The principle is that gastric juice is very acidic and can kill most of the incoming bacteria and fungi, preventing many diseases from occurring. However, even if stomach acid kills most of the foreign bacteria, there is always a great chance of death, such as Helicobacter pylori. Helicobacter pylori contains an enzyme that can create a protective layer around the bacteria to resist the acid killing. Helicobacter pylori can also firmly adhere to cells in the stomach wall to avoid being discharged into the intestine by the stomach together with food. This has hidden dangers for gastritis, gastric ulcer, stomach cancer and other diseases. Many people are not accustomed to using common chopsticks, which also allows the bacteria in the saliva to have the opportunity to spread the food through the chopsticks and cross-infect each other.
Eat supper, smoking, careful carcinogens
Many people have the habit of eating supper. Often eat supper, the stomach is not fully rested, mucosal repair can not be carried out smoothly, but also a predisposing factor for gastric cancer. Barbecues are becoming more and more popular in the supper market. This kind of food may use reconstituted oils repeatedly. The oil contains a lot of carcinogens. "A cigarette after a meal is more than a living god." In fact, this is also a very stomach-inducing practice because tobacco contains a large number of carcinogens. After a meal, smoking causes more carcinogens to be absorbed.
At present, China's medical insurance does not include gastroscopy screening projects, and extensive screening of gastroscopes is not realistic. It is recommended that the following six types of high-risk groups undergo gastroscopy every 1-2 years. At the same time, he also recommends 4-5 years for patients with gastrointestinal diseases. Do a colonoscopy.
Six high-risk groups need regular gastroscopy
1. People over 45 years old;
2, old stomach patients, or infected with Helicobacter pylori;
3, regular consumption of preserved food and smoked, barbecue food;
4, have stomach polyps or stomach surgery;
5. There is a family history of gastric cancer;
6, regular entertainment, excessive tobacco and alcohol, gluttony.
