Friday April 26, 2013 (foodconsumer.org) -- A new study in PLOs ONe suggests that men eating a high amount of fish in early and midlife does not reduce the risk for overall or advanced prostate cancer.

The study led by Johanna E. Torfadottir from University of Iceland in Reykjavik, Iceland and colleagues shows that high fish consumption in early and midlife was not correlated with the risk for overall or advanced prostate cancer.

The study of 2268 of whom 214 prevalent and 133 incident prostate cancer cases were identified also shows that eating salted or smoked fish was associated with 2-fold increased risk for advanced prostate cancer both in early and later life.

 However, men consuming fish oil in later life, but not in early or midlife were found to have a 57% reduced risk for advanced prostate cancer risk.

The researchers concluded "Salted or smoked fish may increase risk of advanced prostate cancer, whereas fish oil consumption may be protective against progression of prostate cancer in elderly men."

"In a setting with very high fish consumption, no association was found between overall fish consumption in early or midlife and prostate cancer risk."
