Potassium‑Salt Switch Could Save Millions

A Nature Health modelling study from The George Institute estimates that replacing regular sodium salt with potassium‑enriched salt globally could prevent roughly 3 million deaths and tens of millions of hypertension cases and DALYs per year, though overconsumption risks (hyperkalaemia) remain for some groups. Implementation would require large‑scale reform by food manufacturers and expanded potassium chloride production, and even partial household replacement shows substantial benefits. — This reframes a common nutritional tweak (salt composition) as a feasible, high‑impact public‑health lever that implicates industry production, regulatory choices, and equity/safety trade‑offs worldwide.
