New findings reinforce potassium’s role in supporting healthy blood pressure
Researchers from the George Institute in Australia report that increasing potassium intake while reducing sodium can help normalize blood pressure. These observations are documented in Human Hypertension. The study builds on a broader body of work showing how mineral balance in the diet influences cardiovascular health.
In the earlier Salt Substitution and Stroke Study, data from 20,995 participants were analyzed to assess how substituting regular salt with potassium-enriched salt affects health outcomes. Conducted by George Institute scientists, the study demonstrated a 14% lower risk of stroke, a 13% lower risk of serious cardiovascular disease, and a 12% lower risk of premature death when potassium-rich salt was used instead of conventional salt. These findings were reported alongside subsequent analysis that integrates additional external data sources on sodium and potassium intake and blood pressure.
The combined results indicate that the most meaningful health gains come not merely from cutting sodium, but from elevating potassium intake. This shift in focus aligns with broader nutrition research that links higher potassium levels to better blood pressure control and reduced cardiovascular risk.

Potassium is a mineral present in many foods, including legumes, nuts, vegetables, leafy greens, and fruits. It is noted that food processing often lowers potassium content, replacing it with sodium, which is frequently cheaper to use. This dynamic helps explain why dietary patterns and product formulations can impact blood pressure and heart health.
Some individuals with high blood pressure may find it challenging to follow dietary guidelines that advocate increasing potassium. A practical approach suggested by researchers is to replace regular table salt with a potassium-enriched alternative, which can simplify adherence while supporting healthier mineral balance.
Historically, the question of whether to replace standard table salt with sea salt has been considered in public health nutrition, but the current evidence emphasizes potassium supplementation via salt substitutes as a clearer, actionable option for many people.
