“Cutting down on the amount of salt has no clear benefits in terms of likelihood of dying or experiencing cardiovascular disease.”-Cochrane Database of Systematic Reviews

No fewer than seven international studies have concluded that reducing salt in your diet does not reduce the chance of death.

A moderately low salt diet might reduce your blood pressure, but there is no evidence it will prolong your life.  However, there is evidence that people who have congestive heart failure might increase there chance of death with a low salt diet.

This makes sense to me, because salt, along with potassium, helps prevent your muscles from cramping.  Your heart is a muscle.

The studies looked at 6,000 people.  Researchers admit they need to do more detailed studies, like looking at cardiovascular morbidity in people with normal or high blood pressure.
