Cacao and cocoa may sound similar, but both of them are unique when it comes to taste, nutrition, and cost. Cacao is the purest form of chocolate you can consume, which means it is raw and much less processed than cocoa powder or chocolate bars. Cacao is thought to be the highest source of antioxidants of all foods and the highest source of magnesium of all foods. It has been used throughout many cultures for years for health purposes and even used as a high trade commodity.
