1, develop good eating habits: the diet must be regularly quantified, and it is forbidden to eat too fast, overeat or eat too hot food, so as not to cause irritation or damage to the gastric mucosa.

2. Avoid eating pickled food for a long time: eat less or no pickled vegetables, which contain a lot of nitrite and secondary amines. Under the action of acidity in the stomach, nitrosamines can be synthesized, which are very powerful carcinogens.

3. Eat less smoked and fried foods: Smoked fish and bacon usually contain a lot of carcinogens, and baked and fried foods, including reused cooking oil, also contain such carcinogens.
