The Claim
In U.S. adults without hypertension medication or baseline disease, a 1 g/d increase in sodium intake is associated with a 0.23 mmHg increase in systolic blood pressure, with body mass index mediating this relationship, after controlling for age, sex, socioeconomic status, smoking, alcohol, physical activity, calorie intake, fluid intake, and potassium intake.
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.
For U.S. adults without high blood pressure or preexisting disease, consuming 1 gram more sodium per day is linked to a 0.23 mmHg rise in systolic blood pressure, and this effect is explained by changes in body mass index, even when accounting for other lifestyle and dietary factors.
See the scientific wording
In U.S. adults without hypertension medication or baseline disease, a 1 g/d increase in sodium intake is associated with a 0.23 mmHg increase in systolic blood pressure mediated through body mass index, independent of age, sex, socioeconomic status, smoking, alcohol, physical activity, calorie intake, fluid intake, and potassium intake.
Eating more salt causes the body to hold onto more water, which makes fat tissue grow slightly larger. This extra fat puts pressure on blood vessels, making the heart work harder to push blood through, which raises blood pressure.
What the research says
1 studyThis study found that when people eat more salt, their blood pressure goes up a little, and part of that increase happens because salt is linked to gaining a bit more weight. Even after accounting for things like exercise, diet, and age, this pattern still held true.
