Omega-3 Fatty Acids Lead to Increased Risk of Prostate
Cancer?
According to a new study, high levels of heart-healthy
omega-3 fatty acids in the blood may lead to an increased
risk of developing an aggressive form of prostate cancer. On
the flip side, however, processing high levels of
particularly unhealthy trans-fatty acids may in turn lower
the risk of prostate cancer.
In order to come to their conclusions, researchers
analyzed data from a U.S. study comprised of over 3,400 men.
In this analysis, they discovered that those men with the
highest blood percentages of decosahexaenoic acid (DHA) were
nearly two-and-a-half times more likely to develop
aggressive prostate cancer than those with the lowest levels
of DHA.
Further, the study noted that the risk of aggressive
prostate cancer was nearly 50 percent less in men with the
highest levels of trans-fatty acids being processed.
Its worth noting, however, that the study showed no
real connection between prostate cancer risk and omega-6
fatty acids that are found in most vegetable oils,
directly.
"We were stunned to see these results, and we spent a lot
of time making sure the analyses were correct," Theodore M.
Brasky, a postdoctoral research fellow in Hutchinson's
Cancer Prevention Program, said in a Hutchinson news
release.
"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 and shine a light
on the complexity of studying the association between
nutrition and the risk of various chronic diseases.
"Overall, the beneficial effects of eating fish to
prevent heart disease outweigh any harm related to prostate
cancer risk," Brasky said. "What this study shows is the
complexity of nutrition and its impact on disease risk, and
that we should study such associations rigorously, rather
than make assumptions."
This study appeared in the April 25 online edition of the
American Journal of Epidemiology.
