What food should you never put salt on?

Salt seem to be all the rage recently, especially on sweets. Salted caramels. Salted chocolates.
Additionally, I have friends that seem to take salting to new heights. I don’t think there’s a fruit they won’t salt, from watermelon to apples. Beer. They salt their beer.

So, it begs the question, what should you never put salt on?
And consider that cheese can be pretty salty, before you go saying things like pie. lol

Companion to my question: What food should bacon not be used in?
