Effects on blood pressure of reduced dietary sodium and the Dietary Approaches to Stop Hypertension (DASH) diet. DASH-Sodium Collaborative Research Group.
BACKGROUND The effect of dietary composition on blood pressure is a subject of public health importance . We studied the effect of different levels of dietary sodium , in conjunction with the Dietary Approaches to Stop Hypertension ( DASH ) diet , which is rich in vegetables , fruits , and low-fat dairy products , in persons with and in those without hypertension . METHODS A total of 412 participants were r and omly assigned to eat either a control diet typical of intake in the United States or the DASH diet . Within the assigned diet , participants ate foods with high , intermediate , and low levels of sodium for 30 consecutive days each , in r and om order . RESULTS Reducing the sodium intake from the high to the intermediate level reduced the systolic blood pressure by 2.1 mm Hg ( P<0.001 ) during the control diet and by 1.3 mm Hg ( P=0.03 ) during the DASH diet . Reducing the sodium intake from the intermediate to the low level caused additional reductions of 4.6 mm Hg during the control diet ( P<0.001 ) and 1.7 mm Hg during the DASH diet ( P<0.01 ) . The effects of sodium were observed in participants with and in those without hypertension , blacks and those of other races , and women and men . The DASH diet was associated with a significantly lower systolic blood pressure at each sodium level ; and the difference was greater with high sodium levels than with low ones . As compared with the control diet with a high sodium level , the DASH diet with a low sodium level led to a mean systolic blood pressure that was 7.1 mm Hg lower in participants without hypertension , and 11.5 mm Hg lower in participants with hypertension . CONCLUSIONS The reduction of sodium intake to levels below the current recommendation of 100 mmol per day and the DASH diet both lower blood pressure substantially , with greater effects in combination than singly . Long-term health benefits will depend on the ability of people to make long-lasting dietary changes and the increased availability of lower-sodium foods
