Gary Taubes (author of this article) goes over the evidence on salt restriction in more detail in Good Calorires, Bad Calories, but it is missing some recent studies indicating negative outcomes for salt restriction. I believe Taubes is often wrong (as most people are) when proposing his hypotheses. But he is very good at tearing down wrong hyptoheses.
