Frederick, perhaps you mean, "NSD or any diet does not have an effect on my condition but others benefit from NSD."

For you to say that you do not "believe" is like a blind man saying "I don't have faith in others that tell me that there is a moon because I can not see it."

For people that get relief from NSD there are multiple scientific reasons that have very little to do with faith/belief.

Perhaps just as autism is a spectrum so is AS and you are in the deep end. Furthermore I suspect that there are many people in this forum that have AS-like symptoms but are hard pressed to have bone destruction and the formation of the bamboo spine mainly because their cycle of damage and healing is better functioning since the environmental factors that got into their body is having less of an effect on the repair mechanism.

What is common between everyone here is underlying inflammation in the connective tissues but the triggers are probably more numerous than the number of people here. Many on this forum probably do not have true AS and perhaps those are the people that get great relief from NDS/LSD.

Furthermore, even if someone has radiological evidence of AS it possibly is misinterpreted.

Just my hypothesis.
