Being you can't do whole wheat or oats that doesn't leave many options. Corn cereals would be the only normal alternative. Corn chex, honeycomb and organic corn flakes along with various sugary but not HFCS kids cereals with a corn base (like cap'n crunch).
-------------------- 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!
