While 100% fruit juices are much healthier than sugary sodas, pomegranate juice was ranked #1 according to a UCLA study based on levels of antioxidants. Pomegranate juice was ranked highest because it contained the most of each type of antioxidant. Juice that has a very vivid color (like most berries) typically has a higher level of antioxidants. Other juices that were high on the list include the following: Concord grape juice, blueberry juice, black cherry juice, acai juice, cranberry juice, orange juice and apple juice.
