You may have been misled by my autocorrect. I meant "tautology" not "totality". Saying that "too much" is bad for you will always be true because by definition "too much" is more than you should have. The problem is that, in nutrition, we usually don't know how much is too much (outside of absurd levels that aren't commonly reached). We know that reducing sodium may be harmful. It's possible that attempting to reduce sodium below what the average person consumes may be harmful (or may be harmful for some portion of the population). We don't know what is the "ideal" level or range of sodium. So, yes, it is true that "too much" sodium is bad for you, but we don't really know how much is too much, or even if the amounts that people eat today are actually too much for the typical person.
