Omega-3 fatty acids and cancer

 Omega -3 fatty acids and cancer?

Though there are several health benefits of taking an omega-3 fatty acid supplement, this recent study suggests that cancer prevention may not be one of them:

"CONTEXT: Omega-3 fatty acids are purported to reduce the risk of cancer. Studies have reported mixed results."

"CONCLUSIONS: A large body of literature spanning numerous cohorts from many countries and with different demographic characteristics does not provide evidence to suggest a significant association between omega-3 fatty acids and cancer incidence. Dietary supplementation with omega-3 fatty acids is unlikely to prevent cancer."
