Blueberries have the highest antioxidant capacity of all fresh fruit. They promote immune functions by raising hemoglobin and oxygen in the blood. Quercetin is the powerful flavonoid which has demonstrated antioxidant and anti-carcinogenic activities, plus several population studies suggest it also offers significant protection against cardiovascular disease.
