Salt is not unhealthy. It's sodium chloride. Both sodium and chloride are essential electrolytes. Your body can't make them, so you need to get them in your diet.It's the salt content that's over the top, and they are way too expensive for the nutrition you get.
People who are taking certain medications or have specific medical conditions such as liver or kidney disease may benefit from restricting sodium intake. But healthy folks don't have to worry about it. Excess sodium is excreted.
