A study, presented at the American Heart Association's annual meeting in New Orleans, adds to mounting evidence that high levels of salt can take a heavy toll on cardiovascular health. One in ten heart-related deaths is attributed to salt.

FOX News Radio's Bill Vitka reports:

Sodium Chloride is considered more dangerous than even sugary drinks.

The new study, which was conducted by the same Harvard research team, links too much salt to nearly 2.3 million heart-related deaths worldwide. 15% of all deaths from heart attacks, stroke and other cardiovascular disease.

The salt industry says the study is unrealistic and misleading. Adding no country in the world adheres to the salt standard recommended by the Harvard team, who say 1,000 milligrams a day is the ideal. That is less than half the upper limit recommended by the CDC.
