Just wondering - humans need salt to live (I assume that most or all animals do too), but thousands of years ago, unless you were living by the sea and eating seafood, where did people get their salt intake from? I know that there are saltmines and things, but does salt occur naturally in any plants or animals (other than marine)?
I mean, if hypothetically there were suddenly only a few people living in the middle of Britain, and there was no food in the supermarkeys etc, and the people didnt KNOW they needed salt, would they all die?
I hope this question makes sense..I know people can get ill from a LACK of salt.
