The Claim
In the Salt Substitute and Stroke Study, modeling approaches estimated that sodium reduction contributed between 12% and 39% to the lowering of systolic blood pressure, suggesting substantial uncertainty regarding its relative importance compared to potassium increase.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Scientists tried to figure out how much of the blood pressure drop in a big study was due to eating less salt versus eating more potassium — and they found it’s hard to say exactly how much each one helped, because the numbers varied a lot depending on how they did the math.
See the scientific wording
The estimated contribution of sodium reduction to systolic blood pressure lowering in the Salt Substitute and Stroke Study ranged from 12% to 39% across multiple modeling approaches, indicating substantial uncertainty about its relative role compared to potassium increase.
What the research says
1 studyThe study looked at a special salt that has less sodium and more potassium, and found that while lowering sodium helped lower blood pressure a little, most of the benefit came from the extra potassium — and we can’t be sure exactly how much each part helped, which is what the claim says.
