Salt 101: A brief history on salt + you

Turns out, you're one salty organism.

Humans share very real similarities with the oceans that make up 71% of the Earth’s surface, which also make up 99% of the Earth's total living space. Sodium Chloride, aka salt, constitutes 90% of the entire oceans mineral content, which is the same percentage of mineral content found in the human bloodstream.  From the ocean, came life, where cells could only survive within a narrow range of electrolyte levels in the extracellular fluid that bathes them. Thus, the development of several salt regulating systems had to occur for life to thrive, which are still prevalent in our bodies today, including our skin, adrenal glands and kidneys. These systems drive us to seek out and retain salt when we need it, and secrete it when we don't.

Wait, are you saying...

Yep. You evolved from an extremely salty environment, and took with you the ability to thrive in not-so-salty environments with bodily systems that control the precise electrolyte levels that facilitates cell life.
