We tend to ignore our digestive systems-the ever-ready, always reliable iron-clad stomachs of our youth, into which we stuffed pizza, peppers and beer-until diarrhea, gas, heartburn, bloating, constipation, stomach pain or other, much more serious, problems develop.

According to the National Institutes of Health, more than 62 million Americans experience some type of digestive distress. More than 10 million people suffer from hemorrhoids, nearly 3 million from gastritis and duodenitis, 2.3 million from inflammatory bowel disease, almost 4.5 million from constipation and 1.4 million from irritable colon. (Statistics from Digestive Diseases in the United States: Epidemiology and Impact, edited by James E. Everhart and published in 1994 in Washington, DC, by the US Department of Health and Human Services, Public Health Service, National Institutes of Health, National Institute of Diabetes and Digestive and Kidney Diseases.)

Many conditions such as hemorrhoids or constipation are relatively benign, while others, notably chronic liver disease, malignancies and ulcers, can be life-threatening.

In my long career as a chiropractor with an intense interest in nutrition, I have studied and written about the powers of enzyme therapy to prevent and treat the common and related problems of indigestion, heartburn, gas, lactose intolerance and constipation.

Poor Digestion: The Costs
Impaired digestion takes a dangerously high toll in causing nutrient deficiencies. For example, the stomach needs sufficient hydrochloric acid to activate the digestive enzyme pepsin, a substance which helps break down the proteins you eat into the short chains of amino acids (protein building blocks) that go into strong muscles, fight disease and produce a healthy supply of blood.

Poor digestion can also impair your absorption of carbohydrates and fats as well as many vitamins and minerals. Vitamin E, for example, is fat soluble, that is, stored for long periods in the body's fat cells, rather than rapidly excreted like the water soluble vitamin C.

Vitamin Absorption
Impaired pancreatic function, or insufficient lipase or bile production, will inhibit fat digestion, possibly causing insufficient absorption of vitamin E, according to the book Present Knowledge in Nutrition (International Life Sciences Institute, Nutrition Foundation, Washington, DC), which is edited by Myrtle L. Brown.

Thus, any difficulty in digesting and absorbing dietary fat can appreciably decrease vitamin E digestion and absorption. In fact, insufficient fat intake coupled with troubled digestion and absorption can affect the body's use of all the fat soluble vitamins-A, D, E and K.

The Enzyme-Digestion Team
Enzymes are molecules naturally produced by the body. These dynamos are involved in all physiological functions but are probably best known for the many jobs they perform during the process of digestion.

Digestive enzymes break the food you eat down into smaller particles so the body can better absorb vitamins, minerals and other nutrients. Unfortunately, in many cases, we may become deficient in digestive enzymes. Or, on the other hand, the enzymes we do produce may be inadequate for proper digestion. Luckily, supplemental enzymes can compensate for nature's shortfalls.

Enzyme Boosters
Supplemental enzymes, available in tablets, capsules, powders and pills, can help enhance the digestive process. The most popular enzymes for this use include:

Proteases help the body digest proteins by breaking them down into their component amino acids.

Lipases break down fat molecules into smaller pieces for better digestion.

Amylases break down carbohydrates.

Digestive enzymes also function in a wide variety of ways:

They detoxify and cleanse the colon and stimulate the beneficial bacteria in the gut, thereby helping relieve a number of digestion-related disorders.

They help mobilize and remove toxic products from the body.

Supplemental enzymes can be used in basically three ways: as digestive aids, taken with or just prior to meals to help break down foods, freeing their nutrients for absorption and use by the body; as systemic enzyme therapy taken between meals and intended to be absorbed into the bloodstream and carried throughout the body to work intensively and thoroughly at the cellular level. They are consumed between meals to avoid mixing them with food as it is consumed.

Energizing Enzymes
Enzymes used systemically can energize the digestive, immune, cardiovascular and nervous systems. In addition, they can also help fight viruses, bacteria, toxins and inflammation, a common symptom with many digestive disorders including diverticulitis and gastritis.

The third way to take supplemental enzymes is in a form I call Enzyme Absorption System Enhancers (EASE), commercially produced enzymes combined with herbs, vitamins, minerals and other nutrients designed to improve their activity, absorption and bioavailability (readiness and ease with which the body can take them up).

Enzymes for Common Conditions
From my extensive research and experience, enzymes as digestive aids, in systemic enzyme therapy as as EASE, can treat more than 150 common health conditions.

Choose your enzyme supplements carefully, scrutinizing the label thoroughly for:

directions for use formulation (coated or uncoated) the enzymes in the formulation and their sources; a vegetarian would want to avoid enzymes from animal sources and those with allergies should ensure that the formulation is free of potential allergens. However pervasive digestive problems are, there's no reason why they have to get you down, ruin your digestion or inflate you. These are very useful substances: Enzymes can set your digestive system - and most of your body's functions - back on track.

Remember, enzymes are essential keys to the smooth, efficient function of that wonderful machine, the human body. Because enzyme production and activity decrease with age, trauma and illness, make a firm commitment to daily enzyme supplementation for a healthier, happier, longer life.
