Your Heart or Your Prostate?

Omega-3 fatty acids are good for your heart, but a new study published in the American Journal of Epidemiology shows that men with high blood levels of the omega-3 docosahexaenoic acid are at significantly higher risk for developing aggressive prostate cancer, reports The New York Times' Roni Caryn Rabin. Researchers at the Fred Hutchinson Cancer Research Center conducted a prostate cancer prevention trial with 1,658 participants matched with 1,803 controls, and they found that men with the highest levels of DHA in the blood were two and a half times more likely to develop high-grade aggressive prostate cancer than those with lower DHA blood levels, Rabin says. They also found that men with the highest levels of trans fatty acids in the blood, which harm the heart, had half the risk of prostate cancer than men with low levels of trans fatty acids. The researchers say they are very surprised by the findings, but advise men not to change their diets as a man's risk for dying of heart disease is much higher than his risk for developing high-grade prostate cancer.
