Superfoods are fruits and vegetables that are particularly high in certain vitamins or minerals that are essential to the body. Though ‘superfood’ isn’t a scientific designation, it helps is identify the foods that are beneficial for particular bodyparts or processes. For example, blueberries have one of the highest natural concentrations of vitamin C, while acai berries have a higher concentration of vitamin A. Each of these vitamins has an important role to play in the immune system and in the production of new cells.
