2. Salt Protects Against Bacteria
A 2015 TIME magazine article entitled “The Weird Benefit of Eating Salty Food” explains, “Salt, it seems, may be an ancient way for the body to protect itself against bacteria.” The research cited in the article notes salt can ward off harmful microbes (bad things containing bacteria).
Studies involving mice and human cells showed that levels of sodium are higher at an infection site, and that without the salt bacteria can thrive. The article also notes this was discovered by accident—a mouse bitten by cage mates had higher levels of sodium in their skin.
