The Claim

The use of salt substitutes in general adult populations reduces all-cause mortality by 12 fewer deaths per 1000 people and cardiovascular mortality by 9 fewer deaths per 1000 people over time.

What the research says

1 study

  1. Study: Impact of sodium intake on blood pressure, mortality and major cardiovascular events: an umbrella review of systematic reviews and meta-analyses

    This study found that using salt substitutes instead of regular salt leads to fewer deaths from heart problems and other causes — exactly what the claim says. The evidence is strong and comes from many high-quality studies combined.
