Our bodies do so many things that we take for granted such as how our hearts pump and keep blood circulating throughout the body or how the brain has to send out signals throughout the body in order for any part of the body to work. Then there is food. We eat food and don’t ever think of what process the body has to go through to break down that food, absorb the nutrients, vitamins, minerals and then distribute the energy derived from the food.
