Peoples' perception of various tastes vary dramatically, partially through genetic factors (some people are even termed "supertasters,") but also with age. There is research showing that children perceive bitterness especially strongly, and that this attenuates with age.

So when some children say they don't like vegetables, it may not be such an illegitimate claim after all. I personally still cannot stand brussel sprouts, into my mid 20s.

I never had them until my mid-20s, but apparently a lot of people's only experience of brussels sprouts is boiled to death, which allegedly increases their bitterness. I've had them roasted, and they were reasonably good.

Yeah I've seen a study that showed a gene is traced to a 50/50 of people liking cilantro.
