C.S.
I don't know any Rheumatologist's, but my brother has Rheumatoid Arthritis. He stopped taking medication for it and has gone to eating an organic diet. He is the last person on earth I would have ever expected to go organic, but it completely takes away his symptoms. When he goes on vacation or his wife doesn't buy the right groceries his symptoms return within days. He has not gone completely organic, but he eats organically at home and as much as possible for lunch when he's at work. Good luck to you!
(He read a book called Natural Cures before he tried eating organic foods.)
