If you want to maximize your antioxidant benefits from blueberries, go organic! A recent study has directly compared the total antioxidant capacity of organically grown versus non-organically grown highbush blueberries (Vaccinium corymbosum L., var. Bluecrop) and found some very impressive results for the organically grown berries. Organically grown blueberries turned out to have significantly higher concentrations of total phenol antioxidants and total anthocyanin antioxidants than conventionally grown blueberries, as well as significantly higher total antioxidant capacity. Numerous specific antioxidant anthocyanins were measured in the study, including delphinidins, malvidins, and petunidins. The antioxidant flavonoid quercetin was also measured.
