The word was coined during the 1940s after a Canadian newspaper referred to a particular muffin as a "superfood that contained all the known vitamins and some that had not been discovered." It took nearly another 50 years for the idea of superfoods to gain traction.
In the 1990s superfoods were fruits, mainly berries. Pomegranate was supposedly a superfruit above the rest. Today, you can find superfoods in every category, from drinks to dairy products and baked goods such as acai-berry cheesecake.
