Most people who’ve heard of acai berries knows that both of Oprah Winfrey’s good doctors–Dr. Nicholas Perricone (a dermatologist) and Dr. Mehmet Oz (a heart surgeon) gave it their thumbs up for being “one of the most nutrtitious and powerful fruits in the world.” But some people require more convincing than that.

So next time anyone throws doubt your way about the true health benefits of acai berries (clearer skin and a stronger, cleaner cardiovascular system notwithstanding), throw these facts back at them:

A University of Florida Institute of Food and Agricultural Sciences study found that the antioxidants in açai berry extract were effective in destroying human cancer cells and that they triggered a response in leukemia cells that had 86% of them self-destruct.

What’s more, a follow-up to that study, conducted in 2008, found that the human body easily absorbs the antioxidants contained in acai berries benefits.
