This. About a fifth of all people are salt-sensitive. It's a genetic disposition. Most people have no problems, except if they really eat ridiculous amounts, as salt will extend your blood volume, which means more work for your heart. Eating no salt at all is more dangerous than eating a bit too much.What that tends to indicate is that … wow, shocker, foods and minerals impact different people differently.
Then again, I'm going with the advice you quoted further above. Don't eat too much, and see that you eat more plants. Additionally, mix it up. If you don't eat the same all the time, the unhealthy stuff will be diluted out.
