Maiga, your English is just fine. I agree with you that modern science still has yet to find the root cause of AS. So why not try the diet? Of course there won't be enough "official" studies on the diet if they haven't even identified the cause. Thankfully Ebringers findings were enough for me and I am on my way to perfect health again, if not already there. The only reason I continue to come to this forum is to encourage newbies. Other than that, I'm exhausted at trying to convince certain people that it works and just to try it. At this point if I come across people who try over and over again to convince themselves it won't work or there aren't enough studies, etc, etc, I really just don't care If they want to sit in pain the rest of their lives. The point is, if you want to see if it works, you just have to try it and give it a fair chance! It took me at least a month for me to GRADUALLY see a difference. Eventually the flair went away completely after giving up diary and I haven't looked back since.
