Omega-3 Fatty Acids from Fish Better Than Flax at Preventing Cancer, Study Finds
Marine-derived omega-3 fatty acids have a stronger punch than flaxseed and other oils in cancer prevention, being eight times more effective at inhibiting tumor development and growth, according to researchers. The findings are from a study at the University of Guelph in Canada titled, “Marine fish oil is more potent than plant based n-3 polyunsaturated fatty acids in the prevention of mammary tumours," recently published in the Journal of Nutritional Biochemistry. Marine-derived n-3 polyunsaturated fatty acids (PUFA), or omega-3s, like eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have been shown to inhibit the development of mammary tumors in animals. But the effects of plant-derived omega-3 remain controversial. In this study, David Ma and his team aimed to compare the effectiveness of fish-derived omega-3 fatty acids to that of plant-based alfa-linoleic acid (ALA), the major n-3 PUFA in the Western diet. ALA is found in edible seeds such as flaxseed and in oils, such as soy, canola and hemp oil. EPA and DHA are found in marine life, such as fish, algae and phytoplankton. "This study is the first to compare the cancer-fighting potency of plant- versus marine-derived omega-3s on breast tumor development," Ma said in a press release. "There is evidence that both omega-3s from plants and marine sources are protective against cancer and we wanted to determine which form is more effective." Researchers fed the different type of omega-3s to mice with highl
