I think lean fish and poultry are easier to digest than the meat alternatives. It isn't easier on the animal though LOL. Most of the fake meats are full of msg type crap and even tofu can cause gassiness when not used to it. Also beans are really difficult and lentils and certain grains and other go-to vegan foods are tough to digest. But vegan diets are lean and uber healthy for the most part, especially when lots of *different* veggies are eaten.
-------------------- 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!
