The Claim

Higher potassium intake is associated with a 24% lower risk of incident stroke in adults, based on moderate-quality observational evidence, but no causal relationship can be established.

What the research says

Supports is higher

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

In plain English

People who eat more potassium-rich foods like bananas and spinach tend to have a 24% lower chance of having a stroke for the first time, but we can’t say for sure that potassium is the reason why.

What the research says

1 study

  1. Study: Effect of increased potassium intake on cardiovascular risk factors and disease: systematic review and meta-analyses

    This study found that people who ate more potassium-rich foods had a 24% lower chance of having a stroke, just like the claim said — and it also admitted we can't be 100% sure it's because of potassium, not other lifestyle factors.
