Effect of the dietary approaches to stop hypertension diet and reduced sodium intake on blood pressure control . The authors hypothesized that the Dietary Approaches to Stop Hypertension ( DASH ) diet and reduced sodium intake would control stage 1 hypertension and reduce high-normal blood pressure ( BP ) to optimal levels . Adults with systolic BP 120-159 mm Hg and diastolic BP 80-95 mm Hg were randomly assigned to receive the DASH diet or a typical American ( control ) diet , consuming three different sodium intakes ( higher=142 mmol/d , intermediate=107 mmol/d , and lower=65 mmol/d ) for 30 days each . BP control was defined as systolic BP < 140 mm Hg and diastolic BP < 90 mm Hg . Among subjects with hypertension at baseline , at higher sodium intake the DASH diet increased BP control two-fold over control ( 63 % vs. 32 % ; 95 % confidence interval , 1.4-2.9 ) . Reducing sodium intake in the control diet group increased BP control 2.3-fold ( 74 % vs. 32 % ; 95 % confidence interval , 1.7-3.2 ) . The maximum BP control rate ( 84 % ) was achieved with the DASH/lower sodium diet . BP became normal or optimal in 71 % of persons consuming the control/lower sodium diet and 77 % of persons consuming the DASH/lower sodium diet . Both the DASH diet and reduced sodium intake improved BP control .
