And so when it comes to sweetness, m- do we see a distinction here in that literature of how this plays out between children or adults that already have a set preference for sweetness, let's say, or a liking, and how that might be changed or not? How do we untangle this type of a distinction?

It's a, this is a very interesting question.

The work that I've done has been all in adults, well, in relation to sweet taste anyway.

I know there is work that's been done in children, and again, this would suggest that exposure has very little impact on preferences.

You're right.

Logically, ought to be more room for change in children whilst they're developing.

There is the possibility that there might be sensitive or critical periods during development where taste preferences change very, very early, and then at the stage where humans are learning to eat solid foods, there's room there.

Absolutely
