Let me preface this by saying I'm not a doctor or scientist, but I've seen two widely reported studies on the effects of salt in the last 10 years.

The first concluded that salt does not cause sustained high blood pressure, but merely causes a temporary increase when high salt content food is consumed. That study concluded that a salty diet was only dangerous to people who already have high blood pressure or have other risk factors making them prone to heart attacks, strokes, etc.
A high salt diet didn't lead to endemic high blood pressure, high cholesterol or any other increased long term risk. I don't see anything here that refutes this. I'm guessing those 100k increased deaths are mainly people who were already in those high risk groups and continued to consume a lot of salt.
Why should everyone have to alter their diet because a minority of people should avoid something? Whats wrong with educating those people to watch out for their own health?
What's next, outlawing peanuts? Mandating soy milk for everyone because some people are lactose intolerant?
