ELI5: Why are young children generally fussy eaters? Shouldn't they be biologically wired to eat anything and everything for strong growth and development?

Kids are wired to eat the stuff that used to be most important to surviving: high-calorie stuff, fatty stuff, etc. They're also more sensitive to bitterness than adults are (bitterness, evolutionary, tends to mean "bad for you"). So when you put a kid in front of a slice of pizza and a brussel sprout, the kid's naturally going to prefer the slice of pizza.
