The heat processing of popular dry or canned commercial pet food destroys nearly all the naturally occurring enzymes. The body will then draw these necessary enzymes from the small reserves of other organs which, after time, can lead to debilitating conditions. Digestive enzymes assist in the breakdown of food enabling nutrients, essential for all cellular functions, to be absorbed into the bloodstream. Also, undigested commercial pet food in the stomach builds up toxins that can weaken and may leave the body open to disease.
