"A high percentage of omega-3 fatty acids in the blood is linked to an increased risk of aggressive prostate cancer Conversely, a high percentage of trans-fatty acids is linked with a lower riskSEATTLE — Apr 25, 2011 — The largest study ever to examine the association of dietary fats and prostate cancer risk has found what's good for the heart may not be good for the prostate.


Analyzing data from a nationwide study involving more than 3,400 men, researchers at Fred Hutchinson Cancer Research Center found that men with the highest blood percentages of docosahexaenoic acid, or DHA, an inflammation-lowering omega-3 fatty acid commonly found in fatty fish, have two-and-a-half-times the risk of developing aggressive, high-grade prostate cancer compared to men with the lowest DHA levels.


Conversely, the study also found that men with the highest blood ratios of trans-fatty acids — which are linked to inflammation and heart disease and abundant in processed foods that contain partially hydrogenated vegetable oils — had a 50 percent reduction in the risk of high-grade prostate cancer. In addition, neither of these fats was associated with the risk of low-grade prostate cancer risk. The researchers also found that omega-6 fatty acids, which are found in most vegetable oils and are linked to inflammation and heart disease, were not associated with prostate cancer risk. They also found that none of the fats were associated with the risk of low-grade prostate cancer.


These findings by Theodore M. Brasky, Ph.D., and colleagues in the Hutchinson Center's Public Health Sciences Division were published online April 25 in the American Journal of Epidemiology.
"We were stunned to see these results and we spent a lot of time making sure the analyses were correct," said Brasky, a postdoctoral research fellow in the Hutchinson Center's Cancer Prevention.


. . .

Among the study participants, very few took fish oil supplements — the most common non-food source of omega-3 fatty acids, which are known to prevent heart disease and other inflammatory conditions. The majority got omega 3s from eating fish.

So based on these findings, should men concerned about heart disease eschew fish oil supplements or grilled salmon in the interest of reducing their risk of aggressive prostate cancer? Brasky and colleagues don't think so.


"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," Brasky said.


The National Cancer Institute funded this study, which also involved researchers from the University of Texas Health Science Center at San Antonio and the NCI."


However this contradicts other studies.

Fatty Fish May Cut Prostate Cancer Risk Study Shows Eating Fish High in Omega-3s Reduces Risk of Aggressive Prostate Cancer"


However, the big difference is that this new study is based on the amount of fats in the blood and most of the other have been on consumption.

It is possible that thing that is common to aggressive PC causes the blood level to be maintained at a high level.

But as someone that has both CAD (70% blockage of the left main and CABG) and a moderate risk PC (3+7) & prostatectomy I am going to maintain my consumption of fish oil and fatty fish.
