The occurrence of stomach cancer is the result of a combination of factors and requires a long and complex development process. Factors affecting the occurrence of stomach cancer include genetic factors, infectious factors, living habits, etc., and some dietary factors may also increase the risk of stomach cancer. This article takes you to a detailed understanding of which factors related to "eating" can affect the occurrence of stomach cancer.

A high-salt diet is an important factor affecting the occurrence and development of stomach cancer. Long-term intake of high salt, pickled foods, etc., can not only destroy the protective mucus layer on the surface of the gastric mucosa, but also provide a good opportunity for carcinogens to attack gastric mucosal cells, Helicobacter pylori in the gastric mucosal cells to grow.

In addition, the content of carcinogens such as nitrites in pickled foods is also higher than that of other foods, which is more likely to induce stomach cancer. Studies have shown that people with a weekly salt intake of at least 100 g have a 5.95-fold increased risk of stomach cancer compared to people who never consume pickled foods, and people with stomach cancer taste saltier than healthy people [1].

A high-fat diet can easily cause obesity. Studies have shown that obesity is associated with the occurrence of a variety of cancers, including stomach cancer, breast cancer, esophageal cancer, colon cancer, etc. [2].

A comprehensive analysis of body mass index [BMI, BMI = weight (kg)/height (m)2] and gastric cancer risk found that overweight and obesity increased the risk of gastric cardia cancer, with a 1.32-fold increase in gastric cardia cancer for every 5 increase in BMI [3].

The harm of excessive alcohol intake to the human body is becoming more and more clear. Alcohol can not only damage the mechanical barrier of the gastric mucosa and trigger chronic inflammation, but also provide a more suitable living environment for Helicobacter pylori in the stomach and aggravate the damage to the gastric mucosa.

There is still controversy over whether alcohol consumption directly increases the incidence of stomach cancer. Studies have shown that people who consume alcohol heavily have a significantly higher risk of stomach cancer than non-alcoholics [4]. Studies have also shown that the amount of alcohol consumed does not increase the risk of stomach cancer in a certain range, but when the amount of alcohol consumed is greater than 50 grams per day, the risk of stomach cancer begins to increase, and as the amount of alcohol is increased, the risk of disease increases [5]. Studies by mainland scholars have shown that the occurrence of stomach cancer is not significantly correlated with alcohol consumption [6]. Therefore, the relationship between alcohol consumption and the occurrence of stomach cancer needs to be further studied and determined.

In addition, some studies have shown that fresh fruits, vegetables, dairy products, green tea, etc. may reduce the risk of stomach cancer. This suggests that diet has a certain impact on the occurrence of stomach cancer, and changing the diet structure may help prevent stomach cancer.
