Salt in Daily Diet

[OakLeaf]

On the history of salt, Mark Kurlansky's book Salt: A World History is a fascinating read. Nowadays salt is so plentiful in the developed world that we pour it all over our roads, and we've forgotten that there was a time when things were different. But the history lingers in place names like Salina, Saltillo, anything with "Lick" in it, etc. Until recently, human history was a quest for salt as much as it was a quest for food and water - mammals, and especially mammals that cool ourselves by sweating, need all three to survive. Think about how animals congregate around exposed salt licks.
