Love your article, Mark. I generally agree with your thought about the effect of what one is exposed to growing up having an impact upon food aversions.
I never had frogs legs or kidney growing up and cannot even try them now. But my grandfather was a chef and made things like beef heart, tongue, rabbit. I was paralyzed with aversion at the dinner table, wound up eating something else, and to this day will not have any of these things. Now, everyone else enjoyed these dishes and urged me to give it a try, but for me - no way.
So, I dunno, maybe the issue is a little more complicated than just a cultural phenomenon. Or, I'm a real jerk!
