What is the relationship between sodium intake and blood pressure in adults aged 19 and older? (DGAC 2010)

Conclusion

A strong body of evidence has documented that in adults, as sodium intake decreases, so does blood pressure.

Adults and Sodium: What is the relationship between sodium and blood pressure in adults aged 19 years and older?

Research Recommendations

Conduct trials that determine the effects of sodium reduction on clinically relevant non-blood pressure variables, such as left ventricular mass, proteinuria and bone mineral density.

Rationale: An inclusive body of evidence suggests that the benefits of a lower sodium intake extend beyond reduced blood pressure. Evidence from cross-sectional studies has documented that sodium is directly associated with left ventricular mass and proteinuria. Clinical trials have also documented that a higher intake of sodium increases urinary calcium excretion.
