The Claim

In the Salt Substitute and Stroke Study, the dose-response relationship between increased potassium intake and reduction in systolic blood pressure varied widely across data sources, with estimated effects ranging from −0.050 to −0.114 mmHg per mmol of potassium, indicating substantial uncertainty in the magnitude of the effect.

In plain English

When people ate more potassium, their blood pressure went down a little—but the amount it dropped varied a lot depending on which study you looked at, so we’re not sure exactly how much potassium helps lower blood pressure.

The dose-response relationship between potassium increase and systolic blood pressure reduction in the Salt Substitute and Stroke Study varied widely across data sources, with estimates ranging from −0.050 to −0.114 mmHg per mmol of potassium, reflecting substantial uncertainty in the effect size.

What the research says

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

    The study found that using salt with more potassium lowered blood pressure, and the amount of drop per extra unit of potassium varied a lot depending on how they calculated it — just like the claim says.
