Bbbbbut it's
sea salt, that's like, more natural, man!!
So it's diluted salt. There's less sodium because there's less sodium chloride. They could lower the sodium content by just putting in less salt; of course that doesn't market as well as sea salt.
Um... you realize that "salt" doesn't mean "sodium chloride," right?
Like KCl, commonly sold as "lite salt," with zero sodium.
True, but generally when the average person thinks "salt," they're thinking sodium chloride, not the nasty bitter stuff known as potassium chloride; nor any of the other salts.
