First, dietary factors are the primary risk factors for gastric cancer. The risk factors for gastric cancer are dietary factors, such as high salt, smoked food and food with high nitrite content. These stimulating factors induce intestinal metaplasia of the stomach and eventually lead to cancer. Smoked food, pickled food and barbecue food are the common delicacies on the dining table of East Asian people. These foods either contain high levels of smoke nitrate or a certain amount of carcinogens, such as - acrylamide, benzopyrene and so on. Appropriate intake may not be harmful, and long-term partial eating will indeed cause harm to the stomach.
