AH-NBC HEATH SAYS FISH OILS ELEVATE PROSTATE CANCER RISKS
Great...just what we need now..........
AF Tweet cites and attaches an article published an hour or so ago by "NBC Health" that says
males taking the highest dosages of Omega 3 fish oils have a 71% greater chance of getting the
highest risk of death form of prostate cancer...
Apparently there is a problem with causality in the study. There is no proof that O3FA causes prostate cancer, only an association. Also it has not been established that the presence of higher O3FA levels in the blood plasma is caused by the intake of food (-supplements). Other studies f.e. indicate that O3FA levels can be raised because of low fat diets, somehow the ratio's get mixed up this way. The occurence of prostate cancer in Japan has increased steadily in the last years (due to an increasing western diet?) but is still significantly lower than in the USA or other western countries. All and all a questionable call of Hutchison University to warn for O3FA on the basis of this study of which the data is derived from other studies, another dubious circumstance.
There are many unknowns. 1. Is DHA the key here? 2. They didn't really research if they were taking fishoilpills or if they were just eating fish 2 times a week. Fish can be full of all sorts of pollutants (which will also be found in low-quality supplements). This is why a prescription grade fishoil, like vascepa, is what you want. Eating big doses of supplements with unknown contents is at own risk.
The same team published a study in 2011 that showed men with the highest levels of one omega-3 fatty acid called docosahexaenoic acid, DHA for short, had double the risk of high-grade prostate cancer. Other studies have had similar findings.
There is no DHA in Vascepa but there is DHA in Lovaza and Epanova.
