Hmm. Probably switching to canola oil, which can survice higher temperatures. Personally, I'd rather they still cooked them in animal fat, since it can survive high temperatures unscathed and actually makes you feel full. Of course, I can totally understand vegetarians not wanting that.

It seems to me that science is coming at us all the time and telling us that what we're eating is bad for us, so another branch of science goes and creates something else, only for it to be discovered many years later that that new thing is just as bad, if not worse. Personally, I think that just eating what the human race ate for millennia is probably the right thing. Of course, that does preclude advancements in foods, but I have yet to see anything that was really a benefit. (Other than hydrogenated vegetable oils making Oreos possible. Mmmmm. Oreos.)
