A global modelling study published in Nature Health suggests that replacing regular table salt with potassium-enriched salt could prevent nearly 3 million deaths and more than 10 million new cases of cardiovascular disease and chronic kidney disease annually.

Led by researchers including Liping Huang and Bruce Neal of The George Institute for Global Health, the study examined the potential health impact of switching to potassium-enriched salt across 193 countries and territories.

Potassium-enriched salt typically replaces part of the sodium chloride in regular salt with potassium chloride. This approach helps reduce sodium intake while increasing potassium intake, both of which can contribute to lower blood pressure and improved cardiovascular health.

According to the study, a worldwide switch could potentially:

  • Prevent approximately 2.96 million deaths annually.
  • Prevent 10.17 million new cases of cardiovascular and chronic kidney diseases.
  • Avoid 69.43 million disability-adjusted life years (DALYs) each year.

The researchers also found that even replacing only the salt used in home cooking and seasoning could prevent approximately 1.85 million deaths annually, highlighting the significant potential of making healthier salt choices.

While potassium-enriched salt offers promising public health benefits, the study highlights the importance of appropriate use, particularly for individuals with advanced kidney disease or those at risk of high blood potassium levels. Medical advice should be sought where necessary.

A Step Towards Better Health

The findings reinforce the importance of reducing sodium intake and making healthier dietary choices. Wider awareness, improved accessibility and responsible adoption of potassium-enriched salt could play an important role in supporting global efforts to reduce high blood pressure and prevent cardiovascular diseases.
