Hi William;

It may be of interest to you to read about enzymes at the following site 
(they talk about Howell's theory) :

From what I gather reading, the body provides it's own enzymes for it's 
digestion and food-borne (exogenous) enzymes play almost no or no 
significant role as an aid to our digestion. However some of the enzymes in 
enzyme supplements taken on an empty stomach might be able to make it to the 
small intestines and would be somewhat helpful.

If you have studies that contradict this, please post to the list.
