I thought this was really interesting about Food Enyzmes,even though I knew we needed them,I will be more careful, about taking them now!! Shirley What role do enzymes play in nutrition? To better understand digestive enzymes, we must first understand the role of NUTRITION in our health. Nutrition is the body's ability to use and metabolize food. There are 45 known essential nutrients that are required in specific amounts for the body to function properly. The term "essential," as used here, means the body cannot synthesize them internally. Therefore all "essential" nutrients must come from exogenous, or outside, sources. In addition to carbohydrates, fats (lipids), complete proteins, and water, there are at least 13 kinds of vitamins, and at least 20 kinds of minerals required for proper metabolic function. Once consumed, the food containing these nutrients must be digested, meaning they must be broken apart and reduced to a state that the nutrients can be absorbed into and transported by the blood stream to all parts of the body. Our body's cells are programmed to direct each nutrient to combine and interact with other nutrients and chemicals to create still other chemicals and compounds which, in turn, are used to build and repair the body's cells, bones, tissue, and organs. The process is called metabolism. Each metabolic reaction is started, controlled, and terminated by enzymes. Without enzymes, no metabolic activity will occur. A body that does not consistently and efficiently metabolize the essential food nutrients necessary for life will fare poorly, and many illnesses are the result of a dietary problem that causes toxemia inside of the body. What are the types of enzymes? Enzymes are classified into three categories. DIGESTIVE ENZYMES FOOD ENZYMES METABOLIC ENZYMES Metabolic enzymes run the body. They exist throughout the body in the organs, the bones, the blood, and inside the cells themselves. These enzymes are instrumental in the growth of new cells and the maintenance of all tissue. Every organ and tissue has its own group of specialized enzymes. They are trained to run and maintain their host. When these enzymes are healthy, robust, and present in adequate numbers, they do an excellent job carrying out their mission. The two kinds of enzymes we are concentrating on here are DIGESTIVE ENZYMES and FOOD ENZYMES. These two are active only within our digestive system. These enzymes have one main job — to digest our food. DIGESTIVE ENZYMES are made by our body's organs. Digestive enzymes are secreted by the salivary glands, stomach, pancreas, and the small intestine. [Technically, digestive enzymes are also considered to be metabolic enzymes whose metabolic role is to digest food. We are specifically distinguishing these particular enzymes here, because they deal with digestion and they can be supplemented from an outside source.] FOOD ENZYMES are already present WITHIN the food we eat. Food enzymes exist naturally in raw food. If the food is cooked, however, the high temperature involved in the cooking process will destroy the enzymes. Digestive enzymes and food enzymes basically serve the same function, which is to digest our food so it can be absorbed through the walls of the small intestine into the blood stream. From this viewpoint the only real difference between food enzymes and digestive enzymes is whether they come from inside our body or from the food we eat. Why are enzymes so important for digestion? Most food, when it is uncooked, contains enough natural food enzymes to digest that food. When you cook the food the enzymes are inactivated (denatured) and can no longer assist in the digestive (breaking down) process. Eating raw food is totally acceptable in some cases and quite unacceptable in others. We eat raw fruit and many raw vegetables, but less often do we eat raw meat, raw fish (not withstanding sushi), or raw pork. Eating uncooked rice is nearly a guaranteed trip to your dentist! So, obviously we cook our food. Here's where the problem occurs. Cooked food contains no enzymes because they have been destroyed. If you eat a meal consisting of a salad, a steak and a baked potato, there are likely enough food enzymes contained in the salad to digest it (break it down so your body can use its nutrients). But, there are no extra enzymes available to help digest the steak or the baked potato. Because the steak and potato are cooked, there are no FOOD ENZYMES available to digest them, so our body must take over and internally create the needed amount of DIGESTIVE ENZYMES to handle the digestive task. The more we depend on our internally generated DIGESTIVE ENZYMES, the more stress we put on our body's systems and organs and the less time these systems and organs have for rebuilding and replacing worn out and damaged cells and tissue and keeping our immune system strong. Your body’s top priority is making sure it has enough nutrients to run its systems. This means digesting food and converting it into nutrients. There is no activity more important to the body than this. This takes a lot of energy and enzymes, particularly if the body must make most or all of these enzymes. Remember that no food can be digested without digestive enzymes. Dr. DicQie Fuller, in her book The Healing Power of Enzymes, emphasizes the importance of enzymes for digestion: "Eighty percent of our body's energy is expended by the digestive process. If you are run down, under stress, living in a very hot or very cold climate, pregnant, or are a frequent air traveler, then enormous quantities of extra enzymes are required by your body. Because our entire system functions through enzymatic action, we must supplement our enzymes. Aging deprives us of our ability to produce necessary enzymes. The medical profession tells us that all disease is due to a lack or imbalance of enzymes. Our very lives are dependent upon them!" Which digestive enzymes digest food? You know that proteins, carbohydrates, and fats are the three main food groups that make up the bulk of our daily diet. A "balanced" diet means we consume the proper proportions of these three basic food groups on a daily basis. This balance, when combined with the assurance that we also get the essential nutrients, can help provide a healthy life — IF we properly process and metabolize these nutrients. To do this we also need an adequate source of the major types of digestive enzymes: Proteases, Amylases, and Lipases. FOOD GROUP % OF DAILY DIET ENZYME CLASS ENZYME'S FUNCTION Proteins 20-25 % Protease Digests Protein Carbohydrates 50-60 % Amylase Digests Carbohydrates Fats 20-30 % Lipase Digests Fat (lipids) There are numerous categories of digestive enzymes, but for the purpose of this discussion, we will cover the three primary classes of digestive enzymes that digest our food. [NOTE: generally speaking, enzymes end with the suffix "ase."] If the proper QUANTITY and required TYPE of enzymes are not present, your body becomes TOXIC from the left over waste of incomplete digestion. This is the reason why most illnesses and diseases are initially a dietary mistake. This can be prevented and it can be reversed. It’s all a matter of having the right amount and the right kind of enzymes available at the right time to prevent your body from becoming a receptacle for pollution and waste — a receptacle that then breeds and harbors disease.
