Enzymes are proteins that create chemical reactions which keep your body functioning.  All plants and animals contain enzymes.

Enzymes have different jobs to do in the body.  Enzymes found in saliva break down starch.  Stomach enzymes break down protein.  Intestinal enzymes break down starches, fats, proteins and carbohydrates thus allowing the nutrients to be absorbed into your bloodstream.

Other enzymes help control biochemical reactions in the body and aid in breathing, detoxifying your organs, cleaning your blood, moving your muscles, cellular repair and producing hormones.

By eating raw foods, you can restock your body's supply of enzymes.  Enzymes can be ruined if they are heated to more than 110º F.  That is why processed, cooked or pasteurized foods contain no enzymes.

If you do not eat raw foods, your body will have to use extra energy to produce the enzymes to break down your food thus straining your digestive system.  By eating raw foods, your body has an easy time and just uses the enzymes you have given it.

Enzyme supplements will increase your enzyme levels, but raw foods are the best source.
