Grog, We are discussing digetive phsyiology...where is the big pharma linkage? Does big pharma benefit from food derived enzymes not participating in digestion? You guys are way to paranoid here...simple discussions seem so threatening to you. Basic physiology...especially digestive...was worked out many years ago by researchers with no interest in drug manufacturing. This topic seems ot have its origins in the 1940-1950's yet there appears to be no evidence for the contentions presented here. I'm sorry I am asking questions no one seems to be able to answer!
