Eli5: how did humans get salt before modern means of transportation

600 views

The human body needs salt to function properly, but surely First Nations of the prairies, people of central Africa or of Central Europe, from the Mongolian steppes and from other landlocked places, couldn’t have access to salt marshes. So where did they get it from?

Vast majority of kingdom animalia needs sodium, did all of the animal kingdom wait billions of years for humans to evolve to invent modern transportation to get sodium?

We got sodium the same way all other animals still get sodium to this day, from our diet.
