Researchers at our United States Department of Agriculture1 are hard at work proving the extreme health benefits of blueberries.  A new study shows that blueberries activate key antioxidant enzymes including glutathione and super oxide dismutase.  The activation of these enzymes significantly reduced arterial plaque formation in an animal model.

Blueberries are well known as an antioxidant fruit, high in anthocyanins.  However, this study showed that the blueberries, independent of their direct antioxidant activity, helped turn on powerful antioxidant enzymes that your body uses to process large amounts of free radicals.  The activation of these enzyme systems was consistent with a 39% - 58% reduction in plaque-forming lesions on the walls of the aorta.

There are many nutrients that help to quench free radicals.  Your savings account of antioxidant nutrition is vital to your health and well being.  Blueberries are a deserving member of your health team.
