American Revolution to weaken their ability to fight. Nations have risen and fallen all because of salt. Salt is the only mineral we can actually eat, which is amazing considering we also throw it on sidewalks, roads, and driveways to melt ice and snow. What’s more amazing is that salt is a compound of two dangerous elements—sodium and chloride. Sodium is an unstable metal that can easily burst into flame, while some forms of chloride can be deadly. But together, they are salt, a product that is essential for life. That’s right. Without salt, humans cannot live. That’s why many civilizations prized salt more than gold. Humans need salt for breathing and for proper food digestion. It helps transport oxygen and nutrients to our organs and cells. Without salt, our bodies would shut down. So please, pass the salt.
