Simple Salt Swap Could Save Thousands of Australian Lives, New Study Finds

Published 2026-11-05

A new study suggests that a simple change to the salt used in Australian kitchens and food factories could prevent more than 2,000 deaths every year. The research points to a possible way to improve public health without asking people to make major changes to their daily lives.

The idea is to replace some of the regular salt, which is mostly sodium chloride, with a salt that contains less sodium and more potassium. Many people in Australia eat more salt than health guidelines recommend. Too much sodium can raise blood pressure, and high blood pressure is linked to heart disease and stroke, which are among the leading causes of death in the country.

Because much of the salt Australians eat comes from processed and packaged foods rather than from the salt shaker, the researchers say that changes made by food manufacturers could have a large effect. If companies used a lower-sodium salt in their products, many people could reduce their intake without noticing a difference in taste. The study suggests that this kind of action could have a bigger impact than advice given to individuals alone.

The findings add to growing calls for government and industry to take action on salt levels in food. Public health experts say that further discussion will be needed before any changes are made, including how the new salt would be labelled and how it would affect different groups of people. For now, the study offers a clear message: small changes to a common ingredient could make a large difference to the health of millions of Australians.
