Modern people face heavy work pressures, often rushing through breakfast and lunch before finally sitting down to a proper meal after work—which inevitably involves rich, fatty foods. Experts warn this lifestyle is unhealthy and significantly increases the risk of stomach cancer.Particularly, frequently consuming high-protein, high-fat foods at night requires extended digestion time in the stomach. This stimulates excessive gastric acid secretion, irritating the stomach lining, weakening its defenses, and potentially causing ulcers. Regular intake of fried, grilled, or cured foods further harms the stomach due to their carcinogenic compounds. Therefore, the primary dietary principle is to prioritize high-fiber plant-based foods—essentially, a vegetarian diet.
Dietary Principles for Preventing Stomach Cancer
"Leftovers." Many people reheat leftover rice to avoid waste. However, studies show that reheated rice becomes difficult to digest and may cause stomach problems over time. Rice's main component is starch, which gradually expands when heated above 60°C, eventually turning into a paste—a process called "gelatinization."The digestive enzymes in the human body can easily hydrolyze these gelatinized starch molecules. However, when gelatinized starch cools, it undergoes a "starch aging" phenomenon, significantly reducing the body's ability to hydrolyze and digest it. Therefore, long-term consumption of reheated leftovers can easily lead to indigestion or even stomach disorders.Processed meat. Swedish scientists indicate that excessive consumption of processed meat products—such as cured meats, sausages, and smoked meats—increases the risk of stomach cancer.After evaluating 15 studies, they found that each 30-gram increase in daily processed meat intake raises the risk of stomach cancer by 15% to 38%. This is because processed meats are typically cured, smoked, or treated with nitrates to extend shelf life—processes that contribute to the increased incidence of stomach cancer.
Fast food. Fried items in fast food are often crispy and hard. If these hard fried foods are swallowed without being chewed thoroughly, stomach contractions can cause them to come into direct contact with the stomach lining, damaging it. If the stomach lining cannot repair itself promptly, inflammation or ulcers may form. For individuals with pre-existing stomach conditions, this can worsen their symptoms.
Green tea for hangovers. Many mistakenly believe drinking green tea after alcohol consumption alleviates hangovers. In reality, combining green tea with alcohol harms the body. Developing gastritis is a mild consequence; severe cases may even lead to gastric ulcers!Green tea contains relatively high levels of caffeine. When combined with alcohol, their interaction irritates the gastric mucosa. Not only does this fail to alleviate drunkenness, but it can trigger various gastric disorders. There have been cases where individuals who habitually drank green tea after drinking to "sober up" developed chronic conditions like gastric ulcers.
Beyond this, what other dietary habits require attention?
1. Cultivate healthy eating habits. Irregular meal times, overeating, eating too quickly, or consuming excessively hot food can damage the stomach lining and are linked to gastric cancer.Similarly, smoking is linked to gastric cancer. Cigarette smoke contains multiple carcinogens and promoters, making it a contributing factor to esophageal and gastric cancers. While alcohol itself isn't carcinogenic, hard liquor irritates the gastric mucosa, damages mucosal tissues, and enhances the absorption of carcinogens. Combining smoking with drinking amplifies the harm, as alcohol increases cell membrane permeability, thereby boosting the absorption of smoke-borne carcinogens.
3. Modify dietary habits: Reduce or eliminate consumption of salt-cured, smoked, fried, and roasted foods. Salt-cured items like salted fish, ham, and cured meats contain high salt levels that compromise gastric mucosal integrity. Additionally, their processing increases levels of the carcinogen 3,4-benzopyrene, promoting gastric cancer development.
4. Avoid moldy foods and limit or eliminate pickled vegetables. These foods contain or can produce high levels of nitrites and secondary amines. Under certain conditions within the body, these can synthesize nitrosamine compounds, which are potent carcinogens.Fresh vegetables, fruits, and milk are rich in vitamins that help repair the body's natural barriers and prevent the synthesis of chemical carcinogens within the body. 6. Actively treat diseases associated with gastric cancer development. Examples include atrophic gastritis with intestinal metaplasia, abnormal hyperplasia, chronic gastric ulcers that do not heal, and gastric polyps. 7. Maintain a cheerful disposition, stay optimistic, and avoid bottling up emotions.
