"It is mentioned 22 times a potential problem in the main part of the web site and the newsletters. It might as well be on the list. "
LOL 22 times is a lot!
Maybe so, but I think the reason it isn't is because it's not a clear-cut trigger food. Most poeple with IBS will agree they cannot tolerate a beef hamburger or steak. Most will agree they can't drink a glass of milk. Most will agree chocolate, coffee and alcohol all affect them. Fructose does not necessarily affect everyone with IBS. Also, it may be because fructose doesn't come in a large dose with most foods, so people who eat it can that tolerate some fructose don't notice symptoms. Fructose is rarely a 'whole food' like milk or meat and so it may be hard to notice any problems from having it.
