China's gastric cancer incidence remains persistently high, with 400,000 new cases annually. In recent years, digestive tract tumors have remained prevalent, linked to unhealthy lifestyles such as a preference for smoked, grilled, high-salt, and pickled foods, along with tobacco and alcohol abuse. These habits disrupt normal gastrointestinal function, severely damage the gastric mucosa, and lead to conditions like gastritis and gastric ulcers, increasing the risk of gastric cancer.
Frequent consumption of pickled vegetables and fish sauce may induce gastric cancer
Despite improved living standards, many unhealthy dietary habits persist, such as a preference for strong flavors and pickled foods. Residents along the Fujian coast in southern China habitually pickle seafood and particularly favor seasonings like fish sauce and shrimp paste. This region is nationally "notorious" as a high-incidence area for gastric cancer.Additionally, residents across multiple provinces share a common dietary habit: long-term consumption of salted pork.
The high salt content in preserved foods directly damages the gastric mucosa. Moreover, the nitrites they contain can transform into nitrosamines under the influence of stomach acid and bacteria, further increasing the risk of gastric cancer.
How should one eat to prevent gastric cancer?
1. Meal Timing: Generally, eating breakfast 20 to 30 minutes after waking is optimal, as appetite is strongest at this time. Additionally, a 4-5 hour interval between breakfast and lunch is ideal, meaning breakfast should be between 7 and 8 a.m. If breakfast is consumed too early, the portion size should be increased accordingly or lunch should be moved forward.
2. Nutritional Balance: The basic requirements are complementary main and side dishes, a balance of dry and wet foods, and a mix of meat and vegetables.
3. Breakfast Considerations: First, ensure adequate hydration. Consume at least 500 milliliters of fluids with breakfast to aid digestion, replenish bodily fluids, eliminate waste, and reduce blood viscosity. Drinking a glass of diluted honey water or plain water upon waking to moisten the stomach and intestines is a key wellness practice. If engaging in morning exercise, drink water first before heading out.
4. Avoid frequent consumption of fried foods. High-fat fried items strain the digestive system, often causing indigestion and potentially triggering or worsening gallbladder or pancreatic disorders. Additionally, repeatedly used cooking oil accumulates carcinogens, increasing cancer risk with regular consumption.
5. Breakfast should be easily digestible. Upon waking, most people have a weak appetite and reduced digestive capacity. Therefore, breakfast foods must be easily digestible, nutrient-rich, and not overly greasy. Pay special attention to avoiding excessively cold foods, as they can diminish digestive function and may cause diarrhea, especially during the cold autumn and winter seasons.
Three Essential Foods for Stomach Cancer Prevention:
Garlic
Widely recognized as an anti-cancer food, garlic possesses significant anti-cancer properties. Studies indicate that populations consuming raw garlic exhibit very low stomach cancer rates. This is because garlic markedly reduces nitrite levels in the stomach, thereby decreasing the potential for nitrosamine synthesis and exerting a protective effect.
Onions
Consuming onions reduces nitrite levels in the stomach. Crucially, onions contain quercetin, a natural anti-cancer compound. Studies reveal that regular onion eaters experience a 25% lower incidence of stomach cancer compared to those who rarely or never eat onions, along with a 30% lower mortality rate from the disease.
Mushrooms
This category includes shiitake mushrooms, button mushrooms, enoki mushrooms, and wood ear mushrooms.Many mushrooms contain anti-cancer compounds that help prevent cancer. For example, the polysaccharides in shiitake mushrooms exhibit exceptionally high anti-cancer efficacy. The polysaccharides in black fungus and white fungus are also potent anti-cancer substances. The abundant dietary fiber and calcium in mushrooms contribute to cancer prevention and enhance the body's immunity.
