“Free radicals are atoms or ions that are missing at least one electron from their outer shell,” Dr. Franklin St. John explains in Natural Awakenings. “When they enter your body, they steal electrons from your healthy cells and turn them into free radicals too. That process continues until the damage is so severe that health issues occur.
“With this in mind, I’d like to discuss anthocyanins, a group of antioxidants that is particularly effective in fighting free radicals. Anthocyanins are what make blueberries so beneficial to your health (and, incidentally, what give them their blue color). The level of anthocyanins in blueberries is very high, and scientific literature has confirmed their effectiveness in fighting free radicals.”
