Eating more salt doesn't just raise blood pressure directly—it also makes people gain weight, and that extra weight raises blood pressure too.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Consuming large amounts of sodium leads to higher blood pressure in adults.
In U.S. adults aged 60 and younger, higher body weight increases the extent to which sodium intake raises blood pressure.
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.
For every additional gram of sodium consumed daily, systolic blood pressure rises by 0.36 mmHg in U.S. adults aged 20 and older without hypertension or baseline disease, with 0.14 mmHg of this rise occurring directly and 0.23 mmHg linked to increased body mass index.
