I use xylitol as a sugar alternative (occasionally) for my home baking, ice cream etc. What is the verdict?

Probably depends on the amount you eat.

Xylitol is a prebiotic, but does have some impact on blood sugar.

Erythritol apparently does not, but may not behave exactly the same in every recipe.

Neither are suited to low FODMAP diet.

Thanks, I have used Erythritol as well. I find them better than sugar or artificial sweeteners, it’s hard to get away with no sweetness when you are feeding a family or friends. I’m not doing FODMAP (as yet).
