Why does the body crave salt?

Answer 1

"The amount of sodium chloride in human blood and in urine is always kept within a very narrow range of 9 g per L (0.9% by weight). Drinking seawater (which contains about 3.5% ions of dissolved sodium chloride) temporarily increases the concentration of sodium chloride in the blood, so the only way to excrete the excess sodium chloride in the urine is by sacrificing internal water from cells. The cells eventually give so much water to try to dilute the salt that they die from dehydration, quickly followed by organs and eventually the organism."

Answer 2

The dry nature of popcorn causes your mouth and throat to dry from lack of saliva, thereby making you want to drink something. The salt also makes you natually thirsty over time so you can drink something to balance the levels of salt and water within your body.

Answer 3

You can actually only taste two substances : salt and sugar. (Your tongue can also detect pH, and we refer to it as sour and bitter). Everything else is smell (try and taste anything with a head cold).

Why are they so important? Because you need salt every day to stay alive.

[The sugar part is just so you won't eat unripe fruit.]

It all means that you're born with two addictions: sugar and salt.

One guess who's taking advantage of that to the point that we're all getting sick from too much of both.
