Heart-healthy diet boosts survival in men with low-risk prostate cancer

Can a healthy diet help men with low-risk prostate cancer live longer? The authors of a new study say “yes.” A long-running Physicians’ Health Study, suggests that a diet that is good for the heart, brain, and other parts of the body may also help keep low-risk prostate cancer at bay. On the flip side, a diet rich in red meat and high-fat dairy foods appears to be hazardous for men with this kind of cancer. It isn’t clear why a diet that protects against heart disease would also protect against death from prostate cancer. Dr. Chavarro speculates that it’s because high-fat foods are easily broken down and absorbed by the digestive system, and so they might provide quick energy sources for growing tumors. Nevertheless, the results suggest that by eating healthily, men with prostate cancer can take a proactive step towards living a long life.
