Oily fish may protect against prostate cancer

oily fish may protect against prostate cancer New study shows eating fish high in Omega 3 such as salmon and mackerel may protect against prostate cancer

UK new outlets today (25 March 09) reported that eating oily fish such as salmon, mackerel and herring could help fight prostate cancer. These oily fish contain high levels of Omega-3, a fatty acid, which has been shown to have health benefits.

The new claims are based on research by scientists at the University of California and reported in Clinical Cancer Research, a journal of the American Association for Cancer Research.

What was the study?

They studied the diets of 466 men diagnosed with aggressive prostate cancer and 478 healthy men. The men were then put into one of four groups based on the amount of omega-3 in their diets. They found that men with the highest level of intake had a 63% reduced risk of "aggressive prostate cancer" compared with those with the lowest intake.

The scientists then divided the men into two groups - those with a gene linked to prostate cancer (Cox-2), and those without it. The study found that even amongst men with the gene, high Omega-3 intake still reduced their risk of advanced prostate cancer.

What does this mean?

According to a spokesman for the study, eating oily fish high in Omega-3 at least once a week effectively reversed the increased risk of contracting advanced prostate cancer for men with the Cox-2 gene.

Of course, this is not a cure for prostate cancer, but the study does show that the risk can be reduced.
