I don't know about glucose-fructose syrup. It would probably depend on how much fructose is actually in there. Not everyone with IBS is fructose-intolerant, so those folks can usually tolerate small amounts of fructose. Large amounts of fructose cause digestive upset for everyone, even if they don't have IBS. But if you're fructose-intolerant, you might not be able to have any.
Sorry not more help here.
