Diet
Foods which are highly spiced, processed, smoked and grilled increase the risk of stomach cancer. Nitrates are used to preserve food. When these nitrates react with the proteins in the body, they make NDMA, which stimulates the tumor production in the stomach and leads to cancer. It is to be noted that people who eat fruits and vegetables are less likely to be diagnosed with stomach cancer. Fruits and green vegetables are rich in antioxidants, which kill harmful bacteria in the stomach and promote digestion. However, healthy eating promotes healing even after surgery.
