Cutting Salt Could Save Thousands of Lives Annually, Studies Reveal

Two recent studies highlight the life-saving potential of cutting salt intake across populations. Researchers in the U.K. and France found that even modest reductions could prevent thousands of heart attacks, strokes, and deaths each year. Health organisations worldwide continue to push for stricter sodium limits to improve public health.

A U.K. study projected that fully meeting the 2024 sodium-reduction targets would lower average salt consumption by 17.5% per person. Over two decades, this could prevent around 103,000 cases of ischemic heart disease and 25,000 strokes. The changes might also add 243,000 quality-adjusted life years while saving the NHS roughly £1 billion.

In France, researchers focused on reducing salt in bread, a staple food. A small cut of 0.35 grams per person daily could prevent about 1,186 deaths annually. The study also showed hospitalisations for ischemic heart disease dropping by 1.04%, with strokes declining by up to 1.05%. Men benefited more than women in the French findings, regardless of age. Meanwhile, global health bodies like the World Health Organization and the American Heart Association recommend daily sodium limits of 2,000 mg and 1,500 mg respectively, though the AHA allows up to 2,300 mg as a maximum.

Both studies stress the need for broad strategies to lower salt consumption. Meeting reduction targets could lead to fewer heart-related illnesses, longer healthy lives, and significant cost savings for healthcare systems. Public health officials now face the challenge of turning these findings into actionable policies.
