> What I meant is that cravings for sugar and salt modulate taste covariantly. Which you seem to get.
Uh, yeah, I think a five year old would get that. Things that one craves taste quite good when they finally hit one's taste buds.
But this:
> Salt really only tastes good when you need salt.
Logically implies that when a person does not need salt, salt does not taste good to that person.
