Why the study?
Does a combined DASH diet and low sodium intake reduce short-term blood pressure variability?
Does a combined DASH diet and low sodium intake reduce short-term blood pressure variability?
Dietary modifications including the DASH diet and low sodium intake can modulate short-term blood pressure variability in addition to absolute blood pressure.
May guide dietary counseling on combined DASH plus low sodium for BP variability; leaves open confirmation in prospective outcome trials.
Dietary sodium and potassium can jointly modulate short-term BPV in addition to BP. Combined DASH diet and low sodium intake may reduce systolic and diastolic ARV via different mechanisms.
