It isn't what you are eating and gas doesn't mean fructose intolerance! It is just common to get gas in the afternoon and evening. That is gassy IBS. You can take time to poo, walk around a lot, eat slower, standing up when eating, eat less at a time and drink fennel tea.
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!
