Omega-3 and Prostate Cancer

A new study released in the American Journal of Epidemiology found that men with higher levels of a fish-based omega-3 fatty acid had increased risks of prostate cancer. Researchers studied 3,461 males from the Prostate Cancer Prevention Trial, and those with the most docosahexaenoic acid (DHA), an omega-3 fatty acid found in fatty fish, were 2.5 times more likely to have high-grade prostate cancer: Conversely, men whose blood was high in trans-fatty acids had a 50 percent reduction in high-grade prostate-cancer risk. “Our findings turn what we know—or rather what we think we know—about diet, inflammation, and the development of prostate cancer on its head,” says researcher Dr. Theodore Bransky.
