The human body is made up of about 60 trillion cells. Each of these cells undergoes 600,000 different chemical reactions during their lifetime. The ubiquitous and countless chemical reactions need numerous catalysts to complete, and the so-called catalyst is actually nothing more than enzyme.
The body’s congenital enzymes deceases as a human ages, so goes our ability of digestionand absorption of foods and detoxify them. As a consequence, our immune system is weakened and cannot defend the invasion of bacteria so that we become prone to illnesses.
Therefore, the three main nutrients, carbohydrates, protein and fat, are like the gasoline that a car needs, while enzymes are like a battery. A well fueled car cannot be launched if there is no battery there. Similarly, for human beings, all the chemical reactions inside the body needs enzymes to complete.
