If they're fructose intolerant (and not everyone with IBS is) then they may have a hard time with even small amounts.
For most IBS folks, fructose is only a trigger in larger amounts - and, fyi, fructose is a hard to digest sugar for everyone. That's why things like bottled apple juice, which is sky high in fructose, can give diarrhea and gas to people who don't even have IBS.
If you're not fructose intolerant, you should be just fine having the amounts of fructose that occur naturally in whole foods such as fruits and honey. Having them with soluble fiber will help (and you'd need it for the insoluble fiber in fruits anyway).
Trust your own body. If you can't tolerate any amount of fructose, avoid it. If you can safely eat fruits when you follow the EFI guidelines, then do so, as you'll get all kinds of nutritional benefits.
