Hi Gerard
Of course it is a subjective decision to decide whether people who claim the diet doesn't work for them have actually tried it properly. Like you, I don't know for certain if there are any. I just think there might be.
All the arguments supporting LSD or NSD are based on the research of Alan Ebringer and he has been central to much of the discussion on this topic. Basically I have been told everyone with AS should respond to diet because his conclusions said so. But now I have learned that his definition of AS and that of the rheumatologist who diagnosed you and me are different. So his studies do not cover the complete range of people diagnosed as AS today. That is why it was necessary to establish the "difference between the AS patients in England from twenty years ago and the patients in Australia nowadays".
I didn't bring up the subject of Ebringer and his research. I have merely responded to it. You may think it is a bit irrelevant but that view is not shared by the 'regulars' who have written on this thread.
