I have a theory that our flavor pallet is flexible, and if you continue to consume something your body things is nourishing, it'll eventually flip a switch in your brain where it becomes palatable.
I'm sure someone has done research on this, but I'm unaware of any.
I'm pretty sure this is known, at least for bitter tastes. Coffee, alcohol, bitter vegetables, dark chocolate, etc., tend to be acquired tastes to at least some degree. Even if you don't dislike them on first try, you probably grew to enjoy them more as you continued trying them.
