Enzymes are protein molecules which carry a vital energy factor needed for every chemical action and reaction that occurs in our body. There are several thousand different enzymes found in the human body. These enzymes can combine with co-enzymes to form nearly 100,000 various chemicals that enable us to see, hear, feel, move, digest food and think. Every organ, every tissue, and all the 100 trillion cells in our body depend upon the reaction of enzymes and their energy factor. Nutrition cannot be explained without describing the part that enzymes play. Enzymes are the single biggest contributing factor to health and longevity.
