I am sorry if I disappoint (well no actually I'm not sorry at all) but I think all this diet rubbish that this Forum has far too much of is a load of nonsense.
It is like all this Holistic or alternative medicine that you hear so much about these days. It is just a load of witchcraft hocus pocus mumbo jumbo that does far more harm than any good. I have yet to come across any actual proof of any such diet working for A.S. patients.
If it was all as simple as a change in diet then every rheumatologist in the land would be recommending his/her patients being on such a diet.
