Digestion of food is essential to the well being of everyone. Without proper digestion we invite countless illnesses to visit us. Digestion begins in the mouth, by chewing food down to the tiniest morsel possible. Most people are in such a rush to eat that they do not chew their food properly and the end result is acid reflex, indigestion, or heartburn. The pre-mentioned maladies can also come from eating poor food combinations, microwaved foods, or processed food daily. When you begin to digest your food you change it from one form into another: it is a physical and chemical process.
