Honestly, every few weeks I think how ironic it would be for me to someday go FF and be better! I hope crow isn't unsafe in that eventuality! But when I look at what foods my instinct tells me are safe for me I can see I am not FI. I haven't done a breath test of it, only diet tests. On another forum sometime ago people recommended a different way to test food allergies. Drink 3 glasses of something on an empty stomach and see what happens- like 3 glasses of milk or three glasses of tomato juice (the acid could cause its own problems though so apple juice would make more sense). If you drank 3 glasses of apple juice and got horrible D or pain it would be so obvious then. But those kind of tests are quicker but hazardous being you could screw yourself up for weeks!
Anyway, either get a FI test or try eating a bunch and see how you feel. If it is stressing you, you have to do something! But lots of people have stabilized with Heather's diet without avoiding fructose. I stabilized the first two summers really well and I must have been eating grapes and melons and sweet corn etc at that time!
-------------------- IBS-A for 20 years with terrible bloating and gas. On the diet since April 2004. Remember this from Heather's information pages:
"You absolutely must eat insoluble fiber foods, and as much as safely possible, but within the IBS dietary guidelines. Treat insoluble fiber foods with suitable caution, and you'll be able to enjoy a wide variety of them, in very healthy quantities, without problem." Please eat IF foods!
