Salt isn't a flavor, it's a flavor enhancer.

I respond to every single one of these that pop up because we are still working on corporate backed bad science. Salt is not bad for you, neither is fat. Sugar is always bad for you and the amount of it you need for it to stop food from going bad is almost hilarious. What canned foods use is a combination of things, one of them being the actual canning process, the combination of boiling to kill as much as possible and then vacuum sealing it means that as long as there is no break in the seal the food is good basically til the end of time.

Y'all motherfuckers need some Alton Brown. Regular table salt does not really have its own flavor or spice, it enhances the flavor of whatever it's combined with, for example when you eat just salt, what you taste is your own saliva and probably your tongue, cheeks, etc.
