For 1000’s of years, individuals who didn’t stay close to the ocean would journey nice distances to commerce for salt. Salt has been the middle of many battles, sometimes called The Salt Wars. And just a few British cities that finish in “wich” (like Droitwich, Middlewich, Nantwich, Northwich, and Leftwich) have been named for and related to their salt works (the cognate wic generally associated to salt works, though wic’s ordinary which means was “dwelling, place, or town”).

Our esteem for salt goes again to Biblical instances.

Salt was valued so extremely that it was equated with foreign money, as you’ll be able to hear in our fashionable phrase “salary,” or “payment in salt.”

But why? What made salt price journeying, generally killing, and sometimes dying for all through historical past?

Why We Like Salt So Much

The most simple purpose for having fun with salt stems from our biology: the human physique requires sodium to carry out features like transmitting nerve impulses, triggering muscle tissues to contract and loosen up, and regulating fluid stability, albeit in small quantities. Salt is the most available and concentrated supply of sodium on the planet.

Throughout historical past’s famines, droughts, and mass migrations, having a reserve of meals that would final for months and even years might imply the distinction between survival and demise.

The Salty Truth About Salt
