Enzymes are living catalysts and the key to good digestion. Present in all whole live foods but destroyed by cooking and processing, digestive enzymes break down foods into nutrients your body can readily digest and utilize. The modern or Standard American Diet (SAD) is lacking in raw foods. Raw foods contain food enzymes that help in the digestive process. Since we do not eat enough raw foods, supplementation is a great way to get the enzymes you need for optimum digestion. The body produces two types of enzymes - metabolic and digestive. When you eat cooked or processed foods, food enzymes are destroyed, forcing the body to supply all of the needed digestive enzymes.
