Omega 3 fatty acid intake associated with a reduction in breast cancer risk

Research published in June in the British Medical Journal provides “solid and robust evidence” that marine omega-3 polyunsaturated fatty acids (n-3 PUFAs) are inversely associated with risk of breast cancer. [1] Researchers from the Zhejijang University in China investigated the association between the consumption of fish and marine n-3 PUFAs and the risk of breast cancer and a potential dose-response association. The systematic review involved 21 independent prospective cohort studies that included over 20,000 cases of breast cancer and involved over 800,000 participants from across the United States, Europe and Asia, with an average follow-up time ranging from 4.3 to 20 years.
