The Health Benefits of a Low-Sodium Diet


Excess sodium intake and a lack of potassium are significant contributors to high blood pressure in Indonesia, leading to calls for the widespread availability of low-sodium potassium-rich salt substitutes (LSSS) to improve public health and reduce healthcare costs. New research from Griffith University highlights the potential benefits of switching from traditional table salt (100% sodium chloride) to low-sodium alternatives in Indonesia.

The Case for Low-Sodium Salt Substitutes

Dr. Leopold Aminde, the lead author from the School of Medicine and Dentistry, emphasized that the World Health Organization (WHO) recommends a population-wide reduction in sodium consumption to mitigate the burden of high blood pressure and related non-communicable diseases. According to Dr. Aminde, LSSS, which look and taste similar to regular table salt, could significantly impact the Indonesian health system by lowering blood pressure and preventing heart attacks, strokes, and kidney disease. This switch could also reduce health expenditure by up to USD 2 billion (IDR 27.7 trillion) over ten years.

Dr. Wahyu Nugraheni, co-author and Head of the Research Centre for Public Health and Nutrition at the National Research and Innovation Agency in Jakarta, noted that Indonesians consume more sodium than is physiologically required. LSSS provide an effortless way for people to reduce their sodium intake and improve their overall health.

Health Benefits and Economic Impact

Implementing LSSS in Indonesia could prevent up to 1.5 million non-fatal cardiovascular disease events and over 640,000 new cases of chronic kidney disease within the first ten years. The most significant health benefits would likely be seen in the low-income segments of the population, who are disproportionately affected by high sodium intake and related health issues.

Policy Implications and Future Directions

The research team hopes these findings will encourage the Indonesian government and other countries to consider reformulating regular salt to LSSS alternatives or facilitating supply chains to make these substitutes more available and affordable. The research findings are expected to inform upcoming WHO guidelines on implementation costs, cost-effectiveness, and the impact on health inequalities.

The research underscores the potential for LSSS to provide significant health benefits and economic savings, making a strong case for their adoption in public health strategies.


Reducing sodium intake and increasing potassium consumption through the use of low-sodium, potassium-rich salt substitutes could have a transformative impact on public health in Indonesia. By preventing numerous cases of cardiovascular disease and chronic kidney disease, these substitutes offer a practical and cost-effective solution to a pressing health issue. The findings of this research highlight the importance of policy reform and the potential for significant health and economic benefits from such interventions.
