I'm a fan of Dr Fettke too and Agree with Jean that Dr Davis's blog is a good resource...also search it for RA, know there are success stories there and on his FB page.

A new book is Sugar Crush, How to Reduce Inflammation, Reverse Nerve Damage and Reclaim Good Health. Inflammation is the focus of the whole book. The doctor himself is on a very strict, no sugar, almost zero carb Ketogenic diet. But he offers a less strict version low carb. http://forum.lowcarber.org/showthre...17&page=1&pp=15

RA is an auto-immune disease and like others that damage nerves, it may also take an extra focus on adding specific nutrients, not only removing the damaging ones.
Dr Terry Wahls famous TEDTalk http://terrywahls.com/category/video/ on reversing her MS has inspired others with different types of AI diseases to try her plan, http://terrywahls.com/how-a-chef-fo...ketogenic-diet/. Her book gives three "levels" of an AI Paleo eating plan.

or a similar AIP plan from Dr Sarah Ballentyne is good...this is a good "cliff notes" of her Book. http://www.thepaleomom.com/the-autoimmune-protocol/
