If you would have said "most of the medical industry today." I would have agreed completely with you- however, I would exempt the disciplines of orthomolecular medicine as well as chiropracters. Not that I agree with the basis of chiropractice, I believe that many of them do have a basic understanding of nutrition, as well as the adherants of orthomolecular medicine as opposed to allopathic prescription pushers.
