Recent research conducted at Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University in Boston and Brunswick Laboratory in Wareham, MA reveals each 100 gram serving (about 3 1/2 oz.) of tart cherry juice concentrate delivers over 12,000 (Oxygen Radical Absorbance Capacity). See the chart to the left for the antioxidant capacity of selected fruits. Higher ORAC values are imperative to maintaining a health body simply because antioxidants fight free radicals in the body. A free radical is an unbalanced and reactive molecule that has lost one or more of its electrons. Free radicals attempt to rob needed electrons from other molecules. If you have ever witnessed a cut apple or potato turn brown, you are witnessing what free radicals can do to healthy molecules. Many people, think of the free radical reaction in your body similar to "cellular rust". Rust on metal is actually an oxidation reaction. While free radicals occur naturally in oru bodies, we increase them by exposing ourselves to many pollutants, cigarette smoke and even ultraviolet radiation from the sun. ORAC units help to fight free radicals. Tart Cherry Juice Concentrate is an excellent source of ORAC to help the body in fight free radicals.
