The Claim
Increasing dietary potassium intake by 1 gram per day is associated with an 11% reduction in stroke risk and a reduction in systolic blood pressure of 3.1 to 3.5 mmHg in individuals with hypertension, independent of sodium intake.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you eat a little more potassium-rich food each day—like bananas or spinach—you might lower your risk of stroke and reduce your blood pressure a bit, even if you don’t change how much salt you eat.
See the scientific wording
Increasing dietary potassium intake by 1 g/day is associated with an 11% reduction in stroke risk and a systolic blood pressure reduction of 3.1–3.5 mmHg in hypertensive individuals, independent of sodium intake.
What the research says
1 studyStudy: Effect of low sodium and high potassium diet on lowering blood pressure and cardiovascular events
The study says eating more potassium-rich foods helps lower blood pressure and reduces stroke risk in people with high blood pressure, which matches what the claim says—even though it didn’t test exactly 1 gram more per day or ignore sodium completely.
