Diet accounts for about another 30 percent of cancer deaths in the North America. Saturated fats from red meats, such as hamburger or steak, and other animal products are linked with several cancers. High salt intake increases the risk of stomach cancer.
Adult obesity increases the risk for cancer of the uterus in women and also appears to increase the risk for cancers in the breast, colon, kidney, and gallbladder. Alcohol consumption increases the risk of cancer of the esophagus and stomach, especially when combined with smoking. A diet high in fatty foods, such as what some consider to be the quintessential American meal—a hamburger and fries—can contribute to many cancers.
