When foods are not digested properly, the nutrients that your pet would ordinarily obtain from his food may not be available. Large, undigested food particles can actually increase the allergic response due to the fact that the body treats these large particles as allergens. Undigested food particles also tend to accumulate in the joints and can contribte to joint problems. Eventually the immune system can ultimately be affected. If your pet must consistently call upon his store of enzymes, then eventually his body may become enzyme-deficient and vulnerable to disease. Not surprisingly, glands and major organs suffer most from enzyme deficiency.
