Did you know that although they look the same, they are actually different? It is not that we have adopted a another name for the same thing.
The base product is cocoa beans. By cold pressing these beans, the fat known as cocoa butter is extracted, giving a new product; raw cacao powder which is rich in live enzymes and is really good for you.
A further process is roasting the raw cacao powder to get cocoa powder. This high temperature phase means the live enzymes are now dead, making the cocoa powder tasty but not as beneficial to your body.
As in many cases, the more processing involved in the making of a product, the more likely it is to be damaging the raw, live, beneficial nature of the food. So keep looking for food that is as natural as possible it will be better for you.
