In the spectrum of nutrition, berries rank near the top, and among berries, none are more nutritious than the Aronia berry. That’s because powerful antioxidants (proanthocyanidins) in Aronia berries remove harmful free oxygen radicals from cells. Research shows that in diabetics, Aronia berry juice reduced blood glucose, and its extracts reduced inflammation and improved immunity. An extract of Aronia berries injected into highly malignant brain tumor cells killed malignant cells within 24 hours without harming healthy cells. And in hard-to-treat cancers, combining Aronia with chemotherapy improved the effectiveness of conventional drugs.
