Salt is something regulated well in all higher organisms. Probably dating from when we evolved in a salt-water ocean. That said, in a modern diet with lots of sodium, but also lots less of other important minerals like magnesium, potassium, etc., who knows? Probably depends on the totality of the diet, for instance if you are getting a lot of salt "artificially", and eating an otherwise nutrient-poor diet, maybe lowering salt intake is a good thing. But if you are eating a varied and mostly natural diet, so that you're getting a wide variety of vitamins, minerals, sun-exposure etc., your absolute sodium intake may not matter much.
