According to a new American study, men who have been diagnosed with prostate cancer should favor a diet rich in fruits, vegetables and fibers with less meat and dairy products in order to improve their chances of survival. A team of researchers from the Harvard Public School of Health has discovered that a healthy diet could increase one’s chances of surviving prostate cancer. Men with prostate cancer who follow a “Western” diet rich in animal proteins, dietary fats and dairy products have a 67% greater chance of dying, all causes combined.
