I actually or stupiditly had a phone consult years ago with David Klein. I asked him point blank that if his diet cured UC, then how come all the GI's don't know about
it or him-and I happen to have one of the leading GI groups in NYC and they were clueless when I mention his name and diet to them. So his answer was- that becasue he was not a doctor himself that they were basically blackballing him as he sent his information out there to the GI communtiy.
