In the study, researchers from the University of California, San Francisco, looked at 466 men with aggressive prostate cancer and 478 healthy men, assessing their eating habits using a food frequency questionnaire. The men were also screened for a variant of a gene known as COX-2, which helps regulate inflammation in the body. A variant of this gene is known to increase the risk of developing prostate cancer.
The study shows that those men who ate dark, fatty fish one to three times a month had a 36% lower risk of prostate cancer as compared with those who had zero dark fish consumption. Furthermore, those who ate dark fish at least once a week had a 57% risk reduction. And those who consumed little to no omega-3 EPA/DHA, and who also carried the specific COX-2 variant, were five times more likely to develop advanced prostate cancer. However, this association was essentially reversed by increasing consumption of omega-3 EPA/DHA.
“This study adds to the growing research that shows that regular omega-3 EPA/DHA consumption by men may lower their risk of developing prostate cancer,” said Ocean Nutrition Canada’s vice president of marketing and communications, Lori Covert. “This is definitely positive news.”
