Eating fruits frequently cannot prevent stomach cancer, and there is no scientific reason and basis for it. To prevent stomach cancer, we need to prevent and treat it through personal dietary habits, living habits, killing Helicobacter pylori and actively treating primary diseases. 1. All fruits or foods do not have the effect of preventing stomach cancer, and you should not believe in any folk remedies or health products. The human body can eat some fresh fruits and vegetables in daily life, such as apples, kiwis, grapes and other fruits, which are rich in minerals, vitamins and nutrients, and can replenish the nutrients needed by the human body. 2. Improve your eating habits: avoid eating barbecued and salted foods. 3. Improve personal life habits: smoking and drinking are important causes of stomach cancer, so you need to quit smoking and drinking to avoid bad life habits. 4. Killing Helicobacter pylori: Helicobacter pylori is an important cause of stomach cancer, so if patients have Helicobacter pylori infection, they should be treated under the guidance of gastroenterologists. 5. Actively treat the primary disease: when the human body suffers from chronic gastritis, peptic ulcer and other diseases, it is necessary to actively apply medication under the guidance of physicians, as gastritis and peptic ulcer are prone to induce cancer when they recur. If patients have symptoms such as hidden pain in the upper abdomen, vomiting blood, blood in stool, etc., they need to go to the hospital for examination, and they can’t use medicines indiscriminately.
