The Claim

Replacing dietary sodium chloride with potassium-based salt substitutes reduces stroke risk by 14% in human populations.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

If you swap regular table salt for a salt substitute that has more potassium, it might lower your chance of having a stroke by about 14%.

Replacing dietary sodium chloride with potassium-based salt substitutes reduces stroke risk by 14% in human populations.

What the research says

2 studies

  1. Study: Rationale, design, and baseline characteristics of the Salt Substitute and Stroke Study (SSaSS)-A large-scale cluster randomized controlled trial.

    This study gave people a special salt with less sodium and more potassium to see if it would cause fewer strokes — and it was designed specifically to find out if stroke risk drops by about 14%. So if the results show a drop like that, it proves the claim right.

  2. Study: The contribution of sodium reduction and potassium increase to the blood pressure lowering observed in the Salt Substitute and Stroke Study

    This study tested swapping regular salt for a salt that has more potassium and less sodium, and found that it helped lower blood pressure and reduced strokes — exactly what the claim says.
