That's arguable. Apparently sodium is a baddie for many, but also not so conclusively a baddie for many others. There are unlimited arguments about this.
I have low level high blood pressure and monitor it twice daily Not only do I take the lowest mg pill prescribed, but I split it, and only take it when I see any kind of rise. (If my bp is normal when I take it, I can faint and hit my head, even at the lowest mg pill) - I've done that twice and almost done it more). I'm very aware of the sodium intake I have - and a once every four months bag of salt and pepper potato chips does not pump my bp. I cook fresh, except for canned tomatoes and beans, though I now make my own beans.
I'm not talking as an expert, but that I've read enough to know that people respond to sodium in varying ways. I also agree that less is more - I'm just not into complete fear mongering. I agree we in general eat way too much with sodium pushed into our food to make it taste better..
