Boston, MA (PRWEB) January 19, 2013
Doctors Health Press, a division of Lombardi Publishing Corporation and publisher of various natural health newsletters, books, and reports, including the popular online Doctors Health Press e-Bulletin, is reporting on a new study out of Philadelphia University that has found fish oil supplements may contain significant levels of contaminants.
As the Doctors Health Press e-Bulletin article (http://www.doctorshealthpress.com/food-and-nutrition-articles/beware-of-tainted-fish-oil-supplements) notes, omega-3s are essential fatty acids that work to keep the brain safe from damaging free radicals and the formation of dangerous plaque, protecting the brain from age-related mental decline. For many people, some of the best sources of omega-3s are fatty fish. However, due to recent concerns around toxins in fish, many have resorted to taking fish oil supplements as a safer way to boost omega-3 intake.
But according to researchers at Philadelphia University, this may not be the best way to go.
As the article “Beware of Tainted Fish Oil Supplements” reports, the researchers noted that because omega-3 polyunsaturated fatty acids (PUFAs) may elicit a whole host of health benefits, including boosting cognitive development, dietary supplements containing omega-3 PUFAs have become increasingly popular. Often, the largest source of beneficial PUFAs in these supplements is fish oil, which, the researchers say may contain significant levels of contaminants, such as polychlorinated biphenyls (PCBs).
The Doctors Health Press e-Bulletin article explains that the researchers conducted a study to evaluate PCB concentrations in 13 over-the-counter children’s dietary supplements containing fish oils or powders. They assessed potential PCB exposure through ingestion of these products on a daily basis.
Outlining the study’s findings, Doctors Health Press e-Bulletin reports that every supplement analyzed contained PCBs. When following serving-size suggestions, average daily exposure values ranged from 2.5 to 50.3 nanograms of PCBs/day. What’s more, daily exposure for the children’s supplements was significantly lower than that previously reported for adult supplements.
According to the Doctors Health Press e-Bulletin article, the researchers concluded that taking fish supplements may increase daily PCB exposure as compared to the ingestion of fresh fish.
