Study Confirms Link Between Omega-3 Fatty Acids And Greater Risk Of Prostate Cancer

July 10, 2013: 12:00 AM EST
Scads of studies in recent years have proclaimed the health benefits of omega-3 polyunsaturated fatty acids – anti-inflammatory EPA, DHA and EHA from fatty fish and fish oils – so it comes as a shock to hear that they may actually have a darker side. In a second large study using data from 834 men diagnosed with prostate cancer, researchers at Fred Hutchinson Cancer Research Center have confirmed that high concentrations of omega-3s were linked to a 71 percent increased risk of high-grade cancer, a 44 percent increase in the risk of low-grade cancer and an overall 43 percent increase in risk for all prostate cancers. The researchers acknowledged they do not yet understand why.
