WHO Recommends Lower-Sodium Salt Substitutes to Reduce Heart Disease Risk

The World Health Organization (WHO) has recommended replacing regular table salt with lower-sodium salt substitutes that contain potassium chloride (KCl) as part of global efforts to reduce sodium intake and prevent cardiovascular diseases.

In a statement on its X account, WHO emphasised that high sodium intake is linked to 1.9 million deaths annually, contributing to conditions such as high blood pressure and heart disease.

The organisation advises reducing daily sodium intake to less than 2 grams—equivalent to consuming less than 5 grams of salt per day, or just under one teaspoon.

While lower-sodium salt substitutes can help in this effort, WHO stressed that these products should only be used in settings with access to healthcare that can monitor kidney health.

This is because higher potassium intake can be harmful to individuals with kidney impairments or other conditions affecting potassium excretion.

Additionally, WHO recommends increasing potassium intake through natural food sources such as beans, peas, nuts, and green vegetables to further support heart health.

The new guidance applies to the general adult population but excludes pregnant women, children, and individuals with kidney disorders.

With 8 million deaths globally linked to poor diets each year, WHO’s push for lower sodium consumption is part of broader efforts to promote healthier eating habits and reduce the burden of heart disease worldwide.
