Already one of the world’s most popular fruits, mangos might also be one of the healthiest. New research, presented at the FASEB Experimental Biology 2012 meeting, not only suggests people who eat mangos have a better diet, but note that the fruit also contains a substance that could have an effect on breast cancer cell proliferation. An exploratory study conducted by researchers at Texas A&M University and presented at FASEB disclosed that a polyphenolic compound found in Keitt mangos has a toxic effect on breast cancer cells. The study—done in vitro (in cells) and in mice—found decreased proliferation of breast cancer cells treated with the polyphenolic extract and reduced tumor size and weight in mice. Although more research is needed, including human clinical trials, researchers hypothesize that the effects of the polyphenolic extract might extend to the consumption of fresh mango. — National Mango Board,
