I don't think there is extra oat bran. It says "whole grain oats (with oat bran)" meaning to me that they want people to know the bran is still in there not that they add more. If you have been eating plain oat bran eating instant oats would be an improvement. I think the chopped-up-ness of the instant oats makes them more tolerable than old fashioned oats.
-------------------- 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!
