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 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”). Isn’t historical past neat?
Our esteem for salt goes again to Biblical instances. When you name somebody “salt of the earth” to point that they embody integrity and composure in troublesome conditions, you’re truly quoting from Matthew 5:13. 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.
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, due to this fact, 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 demise.
The Salty Truth About Salt
So salt is superior. That means we ought to be consuming a lot of it day by day, proper?
Not so quick. Like many important vitamins, salt — and sodium — might 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.

Many docs inform their sufferers to not add salt to their meals due to the danger of quite a few well being issues, particularly hypertension. And for good purpose. One of the most touted sodium information is that 9 out of 10 Americans eat an excessive amount of of it.
Where Most of Our Sodium Comes From

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 enable 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 normally style salty, and bread doesn’t. But…
According to their dietary labels, 120 energy of the bread (three slices) include 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 larger 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.
Cheese and processed meats additionally include a great deal of sodium. After breads and rolls, the largest sources of sodium in the American weight loss plan are, so as, chilly cuts and cured meats, pizza (which is filled with cheese), and poultry. 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 need a lot polarization once you have a look at the information. So let’s separate the sodium information from fiction.
