Actually humans were vegetarians at first. Hunting came later. Personally I don't agree with the idea that wheat is less digestible because humans have only eaten it for 5000 years. That 5000 years is plenty of time to become accustomed to it. Wheat has been the main and sometimes only food source for entire civilizations! If you can't digest it fine- but don't blame history.
-------------------- 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!
