[ELI5] Why do little kids like sweet flavors so much more than adults do?
gpt
There's a few factors.

Firstly, children don't have an upper limit on how sweet a food they'll eat. Finding sweet food sickly isn't something developed until adulthood. Apparently this has something to do with bone growth.

Secondly, children have a lot more taste buds than adults. We lose taste buds as we age.

Thirdly, children are much more sensitive to bitter foods than adults, beyond simply having more taste buds. This is thought to be an defense against accidental poisoning.

All of these add up to children having no reason to dislike sweets, and more reasons to dislike other flavours.
