I managed to get my gut into good shape a few years ago, but in the last year I started eating bread and sugary things too often and I'm fully flared up now again.
My salazopyrin doesnt seem to be working anymore now either.
This diet could be worth a shot.
I'm HLAB27 negative, so i probably have PSA instead of AS, but the same diets seem to work.
Back on Salazopyrin after taking a break for 2 years. Might try going dairy free. Sugar & bread are the main killers for me!
