The federal report on carcinogens doesn't discuss specific foods and cancer risk. However, studies show that consuming large quantities of red meat, preserved meats, salt-preserved meats, and salt probably increases the risk of stomach and colorectal cancers. Research also shows that a diet high in fruits and vegetables may decrease the risks of these cancers. And calorie restriction has been shown to reduce cancer risk for several cancer types.
Eat a healthy calorie-restricted diet rich in whole grains, fruits, and vegetables. Avoid consuming large amounts of fatty foods, red meats, salt, or salt-preserved food.
