Effects of the Dietary Approaches to Stop Hypertension (DASH) Diet on the Pressure-Natriuresis Relationship
Abstract —Blood pressure-lowering mechanisms of the Dietary Approaches to Stop Hypertension ( DASH ) diet , rich in fruits , vegetables , and low-fat dairy foods , were analyzed based on the pressure-natriuresis relationship . Participants ( n=375 ) were r and omly assigned to control or DASH diet groups by using a parallel-group design . They then ate their assigned diet for 3 consecutive 30-day intervention feeding periods , during which sodium intake varied among 3 levels by a r and omly assigned sequence . Urinary sodium excretion rate and mean arterial pressure were measured at the end of each sodium intake level . Mean arterial pressure and urinary sodium excretion were plotted on x and y axes , respectively , for participants eating control and DASH diets and were modeled as linear relationships for simplicity to allow the estimation of the extrapolated x-intercept and slope of the relationships . The DASH diet steepened the slope of the relationship ( 29.5±3.4 vs 64.9±13.1 [mmol/d]/mm Hg , P = 0.0002 ) without significantly shifting the x-intercept ( 94.1±0.5 vs 93.2±0.6 mm Hg , NS ) of the relationship . These data suggest a natriuretic action of the DASH diet
Changes in both systolic and diastolic BP were greater in participants with higher baseline BP or BMI .
The DASH diet improved cardiovascular risk factors and appeared to have greater beneficial effects in subjects with an increased cardiometabolic risk .
