Can certain foods prevent stomach cancer?

Dietary choices can influence stomach cancer risk. Consuming more fruits, vegetables, and whole foods while reducing processed foods, sugar, salt, and inflammatory foods may lower risk. Maintaining a healthy weight, regular exercise, avoiding smoking and excess alcohol, and appropriate cancer screening further support prevention. Genetics remain a major risk factor.
Eating fewer processed and preserved foods, which are generally high in sugar and salt and potential nitrites or nitrates is one advice all teh experts give.
Aim to eat more fruits and vegetables. The antioxidant compounds in produce can provide extra protection against diseases like stomach cancer. When meal planning, try to ensure that half your plate is filled with vegetables.
When possible, follow a Mediterranean diet, which emphasizes whole, plant-based foods and healthy fats. Choose high-quality proteins like lean meat, fish and legumes. Avoid foods known to cause inflammation and eat fewer starches, including potatoes and pasta.
Eating smaller meal portions throughout the day—such as four to six smaller meals throughout the day—rather than sticking to three large meals. Compared to eating a big meal, eating smaller meals causes less stomach stretching and stress on your body and allows for smaller insulin responses.
Exercise has a positive effect on reducing cancer risk.
Obesity—especially excess fat around the midsection—can increase the risk of cancer. This type of fat, called visceral fat, can secrete hormones that increase your risk of cancer.
In addition to weight gain, pay attention to unexplained weight loss. Unexplained weight loss can be the first sign of cancer.
Other things to avoid include smoking and alcohol—particularly beer, which has been shown to increase stomach cancer risk.
