The Claim

Increasing dietary potassium intake by 50 mmol/day reduces systolic blood pressure by 5.3 mmHg and diastolic blood pressure by 3.62 mmHg in adults with hypertension, suggesting a clinically relevant effect on cardiovascular risk reduction in this population.

What the research says

Supports is higher

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

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

If adults with high blood pressure eat more potassium-rich foods—like bananas or spinach—by about 50 mmol per day, their blood pressure numbers go down a bit, which might help lower their risk of heart problems.

What the research says

1 study
  1. Study: Effect of changes in potassium intake on blood pressure: a dose–response meta-analysis of randomized clinical trials (2000–2024)

    This study found that when people with high blood pressure eat more potassium-rich foods, their blood pressure drops by about the same amounts as the claim says — so the claim is backed up by solid science.
