A new study has found that as little as 15 minutes of exercise each day can reduce mortality for individuals with prostate cancer.

Researchers at the Harvard School of Public Health assessed physical activity levels for 2,686 patients enrolled in the Health Professionals Follow-up Study, both before and after diagnosis. They found that men who engaged in three or more hours of exercise like jogging, biking, swimming or playing tennis had a 35 percent lower risk of overall mortality compared to those who didn’t exercise.

They also found that the longer and more briskly the men walked each week affected their risk of dying from the disease. Men who walked four or more hours a week had a 23 percent lower risk of all-cause mortality compared to men who walked less than 20 minutes per week. Men who walked 90 or more minutes at a normal to brisk pace had a 51 percent lower risk of death from any cause than men who walked less than 90 minutes at an easy walking pace.

Recent research has suggested a vegetable-rich diet and pomegranate juice, along with omega-3 fatty acids and soy may lower the risk of prostate cancer.

Nutritional supplements that are routinely recommended to aid in prostate health include vitamin C, vitamin E, selenium and lycopene.
