The Claim

Among adults aged 60 or older with a history of stroke or hypertension, replacing regular salt with a salt substitute containing 75% sodium chloride and 25% potassium chloride reduces the rate of stroke from 33.65 to 29.14 events per 1000 person-years, corresponding to a 14% lower risk (rate ratio 0.86).

In plain English

If you're over 60 and have had a stroke or high blood pressure, switching to a special salt that has less sodium and more potassium might help you have fewer strokes.
