One more thing, about diet & RA-- I happen to be in Montreal right now at the annual meeting of the International Cartilage Repair Society. One of the talks I heard was about diet & osteoarthritis (which is different from rheumatoid arthritis, which was not discussed at all). They mentioned omega-6, and glucosamine, that there is some evidence that these might have an effect on cartilage health. Of course there's not much evidence and it's hard to study because it can't be patented!
