Salt has lengthy occupied a distinguished place in human historical past. But do you may have the all the information on sodium?

For hundreds 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, sometimes called The Salt Wars. And a number of 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 normal 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 really quoting from Matthew 5:13. Salt was valued so extremely that it was equated with forex, as you may hear in our fashionable phrase “salary,” or “payment in salt.”

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

Why We Like Salt So Much

The most elementary cause 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 calm down, and regulating fluid steadiness, 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.

(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 worthy high quality of salt has been its means to protect meals that will 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 may imply the distinction between survival and loss of life.

The Salty Truth About Salt

So salt is superior. That means we needs to be consuming a lot of it day-after-day, proper?

Not so quick. Like many important vitamins, salt — and sodium — could 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. It’s this overuse that offers sodium its dangerous status. Many medical doctors 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 cause. One of the most touted sodium information is that 9 out of 10 Americans devour an excessive amount of of it.

Where Most of Our Sodium Comes From

The cause 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 exterior, 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.
