I want to thank y'all for bringing attention to the vitamins.  I have not knowingly eaten any grains, soy or dairy since I got my diagnosis from Dr. Osborne and have been vigilant about reading labels.  However, I forgot to check my vitamins until I read your post.  I take a bunch of supplements from reputable manufacturers but I was shocked at what I found.  Many of them had some form of rice, soybean oil and corn.  I think it's been a definite help that I cleaned out my vitamin shelf.
