Excessive sodium intake is one of the leading dietary risk factors for high blood pressure, cardiovascular disease, and premature mortality worldwide. According to the World Health Organization (WHO), approximately 1.9 million deaths annually are attributed to high sodium consumption. WHO recommends reducing sodium intake to less than 2 grams per day; however, the global average intake remains above 4.3 grams per day — more than double the recommended limit. In response, WHO has issued a new guideline (January 2025) promoting the use of lower-sodium salt substitutes, especially those enriched with potassium chloride.

Potassium-enriched salt substitutes (PESS) partially replace sodium chloride (common table salt) with potassium chloride, and in some cases, other minerals. These substitutes offer dual benefits: reducing sodium intake and increasing potassium intake — both of which are independently associated with lower blood pressure and reduced risk of heart disease and stroke.

In summary, the use of potassium-enriched salt substitutes is a cost-effective and scientifically supported strategy to lower sodium consumption and improve cardiovascular health outcomes. With appropriate regulation, pricing policies, and public education, these substitutes can play a significant role in national and global sodium reduction strategies.
