Cost-Effectiveness of Household Salt Substitution

Salt and sugar are the current banes of modern nutrition. Developments of modern chronic diseases, like obesity and diabetes, have been contributed by the excessive use of sugar and salt in our diet. 

Recent healthy nutrition advocates the reduction and replacement of sugar and salt. Evidence from population-based studies supported such a strategy. The Salt Substitute and Stroke Study, a five-year cluster randomized controlled trial, demonstrated that replacing regular salt with a reduced-sodium added-

potassium salt substitute reduced the risks of stroke, major adverse cardiovascular events, and premature death among individuals with prior stroke or uncontrolled high blood pressure living in rural China. While the intervention strategy may work, its adoption as a public health policy depends on the cost-effectiveness of public intervention.  

A recent study assessed the cost-effectiveness profile of the Salt Substitute and Stroke Study and found that Replacing regular salt with salt substitute was a cost-saving intervention for the prevention of stroke and improving the quality of life among the study participants.[1]

Currently, Singapore Health Promotion Board advocates the reduction and replacement of dietary salt. I believe that actual physical intervention is required in addition to the usual public health education.
