After a prostate cancer diagnosis, eating a diet higher in red and processed meat, high-fat dairy foods, and refined grains—known as a Western diet—may lead to a significantly higher risk of both prostate cancer-related mortality and overall mortality compared with eating a diet rich in vegetables, fruits, fish, whole grains, and healthy oils, according to a new study from Harvard T.H. Chan School of Public Health.
The study, which appears online June 1, 2015 in the journal Cancer Prevention Research, offers insight on how diet may help improve survivorship for the nearly three million men living with prostate cancer in the U.S.
“There is currently very little evidence to counsel men living with prostate cancer on how they can modify their lifestyle to improve survival. Our results suggest that a heart-healthy diet may benefit these men by specifically reducing their chances of dying of prostate cancer,” said Jorge Chavarro, assistant professor of nutrition and epidemiology at Harvard Chan School and senior author of the study.
