Omega-3s Inhibit Breast Cancer Progression

Mounting evidence suggests a diverse array of health effects of a diet rich in omega-3 fatty acids.  David W.L. Ma, from, the University of Guelph (Canada), and colleagues created a novel transgenic mouse that both produces omega-3 fatty acids and develops aggressive mammary tumors. The team compared those animals to mice genetically engineered only to develop the same tumors.  They found that the mice producing omega-3s developed only two-thirds as many tumors — and tumors were also 30%  smaller — as compared to controls.  The study authors submit that: “we provide, for the first time, unequivocal experimental evidence that [omega-3 fatty acids] is causally linked to tumor prevention.”
