Hypothesis
Replacing Smart Salt for regular salt covering at least 50% of dietary sodium sources in a diet would lead to a 3 to 5 g reduction in sodium intake and consequently a lower SBP.
Conclusion
Replacing regular salt with Smart Salt significantly reduced daily sodium intake and systolic blood pressure in subjects with mildly elevated blood pressure.
Supporting Evidence
- 24-hour urinary sodium excretion decreased significantly in the Smart Salt group.
- Replacement of NaCl with Smart Salt resulted in a significant reduction in systolic blood pressure over 8 weeks.
- Subjects in the Smart Salt group had a 3.3 g difference in sodium intake compared to the control group.
Takeaway
Using a special salt that has less sodium and more potassium and magnesium can help lower blood pressure.
Methodology
A randomized, double-blind, placebo-controlled study with an 8-week intervention period.
Limitations
The sample size was relatively small, and results need to be verified with a larger sample size.
Participant Demographics
Subjects were aged 25-75 years with mildly elevated blood pressure.
