I get frustrated too. I avoid aspartame/sucralose/etc... then it turns out they have stevia/monk fruit extract/etc
oh, and there are some other ones that you might want to avoid.
A low FODMAP diet would cut out not only fructose, but lactose and the -itols like sorbitol, xylitol, and mannitol
The -itols just shouldn't be allowed in food. Consume too much and you best not be out in public.
Don't holiday in Spain or other countries that highly tax sugars. It's itols and aspartame all the way. I literally paniced when I realized I cant/wont eat like 90% or the packaged food in each individual store chain.
