Abstract

The typical American diet includes high salt and low potassium, a pattern linked to elevated blood pressure (BP) in cross-cultural studies. This study compared resting and stress cardiovascular responses on a high salt, low potassium diet to those observed during 2 interventions: salt restriction and potassium supplementation. Forty-seven percent of the primarily normotensive sample (n = 67 adults) were salt sensitive, showing a decrease in meanarterial pressure greater than or equal to 5 mmHg during low salt and equivalent reductions during high potassium. The equivalent benefits of the interventions were maintained, but not enhanced, during exposure to behavioralstress (i.e., no effect on reactivity). Salt resistants (SRs) exhibited nochange in resting or stress BP across the diets. High salt increased cardiac index in both groups, whereas vascular tone was decreased only in the SRgroup. High potassium produced hemodynamic benefits similar to low salt, even with continued high salt intake.
