I don't have ankylosing spondylitis myself, but I know someone who does. I'd like her to try going paleo for a little while.
(A little preliminary research shows that the London AS Diet http://www.kickas.org/londondiet.shtml is already pretty close to paleo.)
Does anyone out there with AS have a paleo story to share? How long did it take you to notice changes? What got better? What got worse? What didn't change?
