According to new research, omega-3 fatty acids could help protect men against advanced prostate cancer.

Scientists from the University of California at San Francisco have determined that a diet rich in omega-3 fatty acids, which can be primarily found in fish, reduces the risk irrespective of an individual’s genetic predisposition, according to Health Day.

The research team arrived at the conclusion after studying 466 men with aggressive prostate cancer and 478 healthy men by collecting their diet information and conducting a genetic test.

"We detected strong protective associations between increasing intake of long-chain omega-3 polyunsaturated fatty acids and more advanced prostate cancer," said John S. Witte, a professor in the Institute for Human Genetics, Epidemiology & Biostatistics at UCSF.

In particular, men who had the highest intake of omega-3 fatty acids had a 63 percent lower risk of aggressive prostate cancer compared to men with the lowest intake.

This study disputes the results of earlier research which did not find the same link.

Eric Jacobs, strategic director of pharmacoepidemiology at the American Cancer Society, also points out that maintaining proper body weight is an important factor reducing the risk of advanced prostate cancer.

A diet rich in fish, as opposed to red and processed meat, is key to a healthy weight.
Those who are concerned about their intake of omega-3 fatty acids, may consider using nutritional supplements.
