Maintaining a healthy weight and good nutrition may be the best way to avoid cancer. A 2009 report from the World Cancer Research Fund and the American Institute for Cancer Research found that roughly one-third of cancers can be attributed to poor diet and physical inactivity. The solution here is simple and would have a big impact. "There's good evidence that maintaining a healthy weight and a more plant-based diet – fruits, vegetables, whole grains – relates to lower risk of some of our most common cancers," says Colditz. He also recommends cutting down on red meats because of their specific link to colon cancer.
