The Claim
A low sodium-to-potassium ratio, resulting from combined low sodium and high potassium intake, is associated with greater blood pressure reduction than either low sodium intake or high potassium intake alone, and this ratio serves as the mechanistic basis for the effectiveness of the DASH diet.
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.
Eating less salt and more potassium together lowers blood pressure better than just cutting salt or just adding potassium alone—and that’s why the DASH diet works so well.
See the scientific wording
The combination of low sodium and high potassium intake, as reflected in a low sodium-to-potassium ratio, is associated with greater blood pressure reduction than either intervention alone, and is the mechanistic basis of the DASH diet’s effectiveness.
What the research says
1 studyStudy: Effect of low sodium and high potassium diet on lowering blood pressure and cardiovascular events
This study says eating less salt and more potassium (like in fruits and veggies) helps lower blood pressure — which is exactly what the DASH diet teaches. So yes, it supports the claim.
