Few people I know like or would willingly consume anything put in front of them. Surely there is something out there you wouldn't eat, don't like, etc. Why is it so hard to imagine that there are people out there (like me) who don't just have this adversion to eating a few things, but rather quite a few?
I'll finish by saying that in the interest of health, I most certainly should be forcing myself to eat things I don't particularly care for or even find downright disgusting. However, to assume that the reason I don't eat such things is nonsense isn't a fair assesment in my opinion.
