> The vast majority of healthy people don't benefit If there's indeed no benefit, then the message is actively harmful, because it causes people who follow it to suffer (from bad-tasting food, in this case). And of course, once they learn that they've essentially been lied to, they'll learn to ignore all "X is healthy/unhealthy for you" messages, which is probably a good thing given how many of them turn out to be wrong. (And if salt does not cause problems for most people, telling them that they need to eat less of it is wrong).
