Now it turns out that may not be good advice for men. A study published in the Journal of the National Cancer Institute indicates that men with higher amounts of omega-3 acids in their blood had a 43% greater chance of developing prostate cancer compared to men with lower levels, CNN notes.
As many as 250,000 men are diagnosed with prostate cancer each year. But only a small fraction of those — about 30,000 will result in death. Prostate cancer is so common that most men will ultimately develop it as they age. However, only high-grade prostate cancer can produce serious illness. The study linked omega-3 acids to both kinds of prostate cancer.
The study did not examine the effect of a diet featuring omega-3 acids compared to the intake fish oil supplements.
In light of the study’s findings, researchers recommend that men who have a family history of prostate cancer talk to their doctors before taking fish oil supplements.
