In revised guidelines, the American Cancer Society put top priority on diet and fitness, saying that eating a nutritious diet, staying active and limiting alcohol are the top things American should do to fight cancer.
“There is evidence that losing weight can reduce the risk for postmenopausal breast cancer, and because of hormonal changes that occur with weight loss, there’s reason to believe it’s beneficial for other cancers as well,” said Colleen Doyle, director of nutrition and physical activity at the American Cancer Society and a co-author of the new guidelines.
The guidelines also say that the standard recommendation – 30 minutes of moderate exercise five days a week – is still good, but it works better with with more strenuous activities such as biking, running or power walking.
Doyle said it’s time people understand they have a say in the future of their health. “Unfortunately, there’s no guarantee. You can do all those things and still get cancer. But the good news is that a lot of people think they don’t have any control over their risk of cancer and we’re here to tell people that absolutely you do have some control.”
