How can one prevent the body from depleting its own supply of enzymes?

Nature solved the problem for us by providing those enzymes in RAW FOODS.  Food

enzymes begin the process of digestion in the stomach. If there are no food enzymes,

the body must produce additional digestive enzymes resulting in fewer metabolic

enzymes. If you feed your dog a diet containing at least 70% raw foods, you're

providing these vital enzymes. Congratulations! Cooking or processing food above 118

degrees Fahrenheit destroys all food enzymes. If your dog's diet consists mainly of

cooked or processed foods, the animals store of metabolic enzymes will be converted

into digestive enzymes. The lack of food enzymes puts a heavier burden on the body to

generate adequate enzymes to complete digestion.

In nature, animals know to seek out those foods that satisfy their nutritional needs.

For example; free-roaming wolves hunt grazing animals whenever possible. Before eating

muscle or bone, the wolves feast on stomach contents, the liver, pancreas, and

intestines -- in other words, they are gorging on enzyme-laden tissues. Wolf pups are

weaned and maintained on regurgitated food, also heavily laced with digestive enzymes.

Unless we provide the same food a wolf enjoys in the wild, adding a digestive enzyme

supplement to each meal may be essential for optimum digestion and overall good

health. A multiple digestive enzyme should contain pancreatin, lipase, oxbile, pepsin,

betain, hydrochloric acid (HCL), bromelain, papain, amylase, and protease.
