koodie - noun Slang. A kid keenly interested in food, especially eating, cooking or watching reruns of Julia Child. A kid who has an ardent or refined interest in food; a mini-gourmet; usually trained by one or both parents to have an unusual, and sometimes fanatic, desire to eat unusual foods. Evolution from the now defunct word “foodie”.Or should that be a kid who's been spending too much time around (possibly very annoying) adults and, if he should happen to enter the company of young persons, will experience ordinary social life as something more complicated than "Mastering the Art of French Cooking"?
Actually, the books discussed at the link seem to be more about getting kids to be more adventurous in eating new foods and not to prefer packaged/junk food. That's all very nice, but it's not so much refinement. Kids shouldn't be picky eaters. And these koodies sound like a new kind of picky.
