I don't doubt that you might have benefited from a reduction in sodium intake but most people won't. The majority of people are not hypersensitive to sodium[1]. Limiting salt to some arbitrarily low number can have negative side effects, for example, my vegetable consumption went up dramatically when I let go of my anxiety over putting salt on them.
