I think many of us had difficulties trying to figure out how diet was effecting our pain. I knew instinctively diet would help me, I just didn't know which diet. There is so much conflicting information out there.
Now that I found NSD, its very simple. NSD works for AS, and probably any other "itis". Much of the info is right here, why wait for the book, start today, the sooner you could be pain free.
