The Anti-Cancer Diet

"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.
