hmm... I don't know why you wouldnt' want to take digestive enzymes just because you have irritated intestines. Perhaps they're thinking that the enzymes will digest the sore, unprotected areas of the intestines. It's kind of a catch-22, because until you start digesting things fully you will have wonky things like lesions messing you up. So my advice would be to take the enzymes or fast. There's no point in eating if you're not digesting. Take marshmallow and slippery elm to protect the lining of your intestines if you feel discomfort.
