Study after study shows omega-3 fatty acids, like those found in fish oil, are great for the heart. But new research suggests the same may not be true for men’s prostates.
Researchers with the Fred Hutchinson Cancer Research Center in Seattle, WA, said that their study found that men with the highest percentage of docosahexaenoic acid – an inflammation-lowering omega-3 fatty acid commonly found in fish – have two-and-a-half times the risk of developing aggressive, high-grade prostate cancer compared to men with the lowest DHA levels.
The researchers also found that men with the highest concentrations of trans-fatty acids, which are linked with heart disease, had a 50-percent reduction of high-grade prostate cancer.
Neither fats were associated with the risk of low-grade prostate cancer.
Lead researcher Theodore M. Brasky said in a statement that he and his colleagues “were stunned” by their findings,” and that they “spent a lot of time making sure the analyses were correct.”
“Our findings turn on 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.”
A full report on the study appears in the April 25 edition of the American Journal of Epidemiology.
