My 3 year old daughter has her instincts intact. She is drug free and vaccination free. She does not watch television. And by the time she was 2, daddy was already eating raw food diets.
I let my daughter taste and choose what she wants. Humans are supposed to have an instinct on what tastes good. I have observed that she loves to eat many different kinds of fruits. I have observed that she loves to eat many different kinds of raw animal foods, her favorites being raw eggs, raw beef and raw fish in that order, yesterday I found out she likes raw squid too, she likes raw goat liver too. And she is the healthiest, densest little girl, denser than her brothers, same observation Aajonus says about raw foodists who eat raw meat.
My daughter will eat celery. But present green leafy vegetables and she will politely brush these aside. She will eat salad greens as long as you have a tasty oily dip.
As for preferring cooked food or raw food… I have observed that my daughter will leave her cooked food prepared by the cook in favor of whatever raw food daddy is eating.
Me and her brothers have observed that eating rice makes raw meat taste bad. So if you want to eat raw meats, you had best stop eating rice.
