Using low-sodium salt instead of regular salt can bring significant health benefits. According to a new study, switching to salt with reduced sodium content could reduce the number of deaths by approximately 400,000 people annually. Furthermore, this could prevent over 1.5 million new cases of heart and kidney diseases.
The study demonstrates how much substantial health benefit a small dietary change can bring. According to the publication in 'Nature Health', if people worldwide started using low-sodium salt, about 3 million deaths and 10.1 million new cases of chronic heart and kidney diseases could be prevented each year. Significant benefits are also expected in India from this change.
The study, conducted by the George Institute of Global Health, analyzed the advantages of replacing regular salt with low-sodium salt in 193 countries. It was found that people whose diet included low-sodium salt showed improved blood pressure control. Fell Bruce Neil, a senior professor at the George Institute, noted that excessive sodium intake combined with insufficient potassium intake is the main cause of high blood pressure. He also emphasized that changing the type of salt can help control hypertension, stroke, heart attacks, and kidney diseases, thereby reducing mortality from these ailments.
In India, the average daily salt intake is estimated at 9.01 grams, which is almost double the World Health Organization's (WHO) recommended limit of 5 grams. This is also one of the causes of high blood pressure in the country. According to the ICMR-INDIAB study for 2023, 315 million people in India, or 35.5% of the entire population, suffer from hypertension. In 2025, the WHO recommended using low-sodium salt based on potassium chloride instead of regular salt for the general public.
