Salt has lengthy occupied a distinguished place in human historical past. But do you have got the all the information on sodium?
For 1000’s of years, individuals who didn’t reside close to the ocean would journey nice distances to commerce for salt. Salt has been the heart of many battles, also known as 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 typically associated to salt works, though wic’s traditional that means was “dwelling, place, or town”). Isn’t historical past neat?
Our esteem for salt goes again to Biblical occasions. When you name somebody “salt of the earth” to point that they embody integrity and composure in tough conditions, you’re truly quoting from Matthew 5:13. Salt was valued so extremely that it was equated with forex, as you’ll be able to hear in our fashionable phrase “salary,” or “payment in salt.”
But why? What made salt value journeying, typically killing, and infrequently 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 mass to contract and chill out, and regulating fluid stability, albeit in small quantities. Salt is the most available and concentrated supply of sodium on the planet.
Salt additionally makes many meals (together with some actually unhealthy ones) style higher. When a handwritten copy of Kentucky Fried Chicken’s secret recipe of 11 herbs and spices was found in the property of Harlan Sanders’ second spouse in 1996, three of the components have been salt, celery salt, and garlic salt. (The doc additionally misspelled “oregano,” which ought to cheer up anybody who struggled in English class and nonetheless aspires to entrepreneurial greatness.)
But wait, there’s extra. Arguably the most useful high quality of salt has been its potential to protect meals that might in any other case spoil. The phrase “salad” comes from salt and initially referred to greens that have been brined and will, subsequently, be eaten uncooked with out spoiling or wilting. 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 dying.
The Salty Truth About Salt
So salt is superior. That means we ought to be consuming a lot of it day-after-day, proper?
Not so quick. Like many important vitamins, salt — and sodium — will be dangerous in extra. And in the fashionable world, processing has devalued salt and made it an affordable and ubiquitous additive that saturates our meals system.

But sodium isn’t simply added to processed meals as a result of salt tastes good. The actual causes are extra troubling. Food producers use salt each to increase the shelf life and to masks the poor style of low-quality components that permit them to promote their merchandise so inexpensively.
A Sodium Comparison Example
Here’s a quiz: What do you suppose is saltier, Pepperidge Farm Very Thin Sliced White Bread or LAY’S Classic Potato Chips? That’s a no brainer, proper? Chips often style salty, and bread doesn’t. But…
According to their dietary labels, 120 energy of the bread (three slices) comprise 230mg of sodium. While 120 energy of the potato chips serve up about half that quantity of sodium (170 mg sodium per 160-calorie serving, to be exact). The purpose the chips style saltier per calorie is that the chips have extra energy per gram as a result of they’re greater in fats (There are 9 energy in a gram of fats, however solely 4 in a gram of carbohydrates or protein). And additionally as a result of salt is on the outdoors, available to your tongue. The great amount of salt in the bread is baked in and doesn’t style salty a lot as disguise and protect the not-so-fresh flour, soybean oil, and components.

Chicken is usually injected with salt or brine to extend the water weight and earn more money from the identical fowl.
With all these troubling sodium information, you’re proper to be cautious. But sodium itself isn’t essentially a nasty man, neither is salt if used appropriately. It seems that the dialog round salt and sodium doesn’t really want a lot polarization whenever you have a look at the information. So let’s separate the sodium information from fiction.
