Hmmm sugars doesn't need to be removed generally, at least not for AS. I personally use honey and fructose in place of sucrose, but that is for different health issues (inflammation in waterworks).
I can't think of anyone here who had AS directly impacted by sugar.. although people on Earthclinic have had their Iritis clear up after removing sucrose. In my experience this is because people like to mix sugar with milky/creamy/fatty foods and THAT is when sucrose becomes an issue for my iritis.
