Is stomach cancer caused by diet?

This statement is somewhat one-sided.

An unhealthy diet does increase the risk of gastric cancer, but the occurrence of gastric cancer is usually the result of multiple factors, and it takes a long and complex development process. Its inducing factors include genetics, environment, living habits, diet, emotions, age, bacterial infection (Helicobacter pylori is a very clear high-risk factor for gastric cancer), etc. Diet is only one of them, so it cannot be simply and crudely said that gastric cancer is caused by eating.

To prevent gastric cancer, it is recommended to develop healthy living and eating habits. For example, eat less pickled, grilled, and smoked foods, quit smoking and drinking. Secondly, if you are infected with Helicobacter pylori, it is recommended to eradicate it in time, which can also effectively prevent gastric cancer. In addition, it is recommended to have regular physical examinations every year and seek medical attention in time if you feel unwell.
