"What you eat and how much you consume makes a difference when it comes to cancer," says Colleen Doyle, R.D., director of nutrition and physical activity for the American Cancer Society. The first step: Limit your intake of sweets and unhealthy fats. Focus on the term "occasional treat," with the stress on occasional. Step two: Incorporate the following foods into your everyday meals and snacks; pick at least two a day for a week's worth of protection. They're nutritional powerhouses and have all shown promise in the fight against cancer.

Fatty fish like salmon, mackerel, herring, lake trout, sardines and albacore tuna are high in omega-3s.
