First direct evidence to show cost-effectiveness of salt substitutes on cardiovascular outcomes

Replacing table salt with a reduced-sodium, added-potassium ‘salt substitute’ is cost-saving and prevents death and disease in people at high risk of having a stroke, according to new research. Salt substitution has been shown to reduce stroke risk by 14 percent and the number of strokes and heart attacks combined by 13 percent, but this new analysis revealed that the costs saved as a result outweighed the cost of the intervention.

The results were presented at the American College of Cardiology Annual Scientific Session in Washington DC on April 3 by Professor Bruce Neal, Executive Director of The George Institute Australia, and published in Circulation.

Senior author Thomas Lung, Senior Research Fellow at The George Institute for Global Health said salt substitutes should now be considered as a key element of any salt reduction campaigns.
