Wondering if the term "picky" eater came from people picking off the stuff they don't like, & eating the rest or vice versa.
You couldn't keep a chocolate cake in the fridge with my aunt around. She would sneak into the fridge & eat all the chocolate frosting off, leaving a bare ugly cake.
In that regard, I'm not "picky."
I like what I like, and am willing to try new things. There are certain foods, where I draw the line. For me, it's mostly about personal preference. Don't want to give a stereotypical (sp?) response here, but "some" of my experience has been that men are not fond of vegetables. Some (not all) are more in favor of meat and potatoes. Men (sorry) mostly rave about their mother's cooking. I think children tend to be picky because they have a limited experience with different kinds of foods - or because it's about power/attention. Could it be that food means a lot of different things to people? Perhaps there's some psychology behind food/eating habits/preferences.
