Here are the problems. Here are the answers. At birth you are given a limited supply of metabolic enzymes which must last you all of your life. They are also an integral part of your Immune system. Digestive enzymes break down your food so that the body can absorb and use the nutrients.
Raw foods contain all the digestive enzymes needed to digest that particular food.
Cooked and processed foods have no active enzymes left in them. Your body tries to help out by borrowing from your own store of metabolic enzymes to assist with the digestion of these incomplete foods. As a result, your immune system can be compromised and your body's enzyme store is placed under frequent stress. The solution is to supplement your enzyme supply with plant enzymes which can replace the enzymes lost in preparation of our food. Plant enzymes are effective through a much wider pH range in your digestive tract than most common animal enzymes.
