Replacing regular salt with a potassium-enriched alternative could prevent almost 3 million deaths and 10 million new cases of cardiovascular and kidney disease each year, according to a new study.
Global Health Benefits
The research, from The George Institute for Global Health, assessed the impact of switching the global salt supply across 193 countries. The findings, published in Nature Health, show significant health gains from the simple dietary change. The study, titled “Global health outcomes from replacing dietary sodium chloride with potassium-enriched salt,” carries the DOI 10.1038/s44360-026-00216-9.
Bruce Neal, a senior professorial fellow at the institute, said the health benefits would be widespread. They could prevent one in 10 cardiovascular deaths in most countries. Consuming too much sodium and not enough potassium are well-known causes of high blood pressure, a major risk factor for strokes and heart attacks. This dual dietary issue is addressed simultaneously by the switch to potassium-enriched salt.
How It Works
Potassium-enriched salt replaces some sodium chloride with potassium chloride. It looks, tastes, and cooks like regular table salt. In 2025, the World Health Organization endorsed its use to help lower blood pressure. Cardiovascular disease is the leading cause of death globally, causing 19.2 million deaths in 2023. The study found that even limited use of the salt substitute would still lead to major health improvements.
One concern is the risk of high potassium levels for people with advanced kidney disease. However, the study found that the benefits still outweigh the risks for this group. Managing this risk is possible through patient education, product labeling, and clinical oversight, according to Vivek Jha, a nephrologist at The George Institute in India.
Industry Challenges
For the switch to be most effective, the food industry needs to be involved. Neal pointed out that in Europe and North America, over 70% of salt intake comes from processed and restaurant foods. Getting these sectors on board is essential for realizing the maximum benefits. This would also require scaling up the production of potassium chloride to meet global demand.
A healthier form of salt could prevent millions of deaths from stroke and heart disease (2026, November 4). While a full global switch is an ambitious goal, it offers a low-cost solution with greater potential than many drug-based treatments.
