Cutting salt could save thousands from deadly strokes and heart disease annually

New research underscores the life-saving potential of reducing salt intake across Europe. Studies in the UK and France demonstrate that even modest cuts could prevent thousands of deaths and serious heart conditions each year. Health experts continue to advocate for stricter sodium limits as evidence of the benefits mounts.

A UK study found that achieving 2024 sodium-reduction targets could lower average salt intake 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 healthy life years and save the NHS approximately £1 billion.

A separate French study focused on reducing salt in bread, a staple in many diets. Cutting sodium there could lower daily intake by 0.35 grams per person. Researchers estimated this would prevent roughly 1,186 deaths annually and reduce hospitalizations for heart disease by 1.04%. Strokes—both hemorrhagic and ischemic—could drop by 1.05% and 0.88% respectively. Men benefited more than women in the French findings, regardless of age. The results align with global recommendations, including the WHO's daily sodium limit of 2,000 mg and the American Heart Association's stricter 1,500 mg ideal. Meanwhile, the US National Academies has set its own 2025 bioavailability targets for adults. Both studies emphasize the need for broad public health measures to combat excessive salt consumption.

The findings bolster calls for stronger salt-reduction policies. Lower sodium intake is linked to fewer heart attacks, strokes, and deaths—while easing pressure on healthcare systems. Experts say population-wide strategies, like reformulating processed foods, could deliver the most significant impact.
