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 .
The DASH diet is an effective nutritional strategy to prevent CVD
The Dietary Approach to Stop Hypertension ( DASH ) is recommended to lower blood pressure ( BP ) , but its effects on cardiometabolic biomarkers are unclear .
A systematic review and meta- analysis of r and omised controlled trials ( RCT ) was conducted to determine the effects of the DASH diet on cardiovascular risk factors .
Blood pressure response to dietary modifications in free-living individuals.
A diet rich in fruits , vegetables , and low-fat dairy foods has been shown to lower blood pressure ( BP ) when all foods are provided . We compared the effect on BP ( measured at home ) of 2 different self-selected diets : a low-sodium , high-potassium diet , rich in fruit and vegetables ( LNAHK ) and a high-calcium diet rich in low-fat dairy foods ( HC ) with a moderate-sodium , high-potassium , high-calcium DASH-type diet , high in fruits , vegetables and low-fat dairy foods ( OD ) . Subjects were r and omly allocated to 2 test diets for 4 wk , the OD and either LNAHK or HC diet , each preceded by a 2 wk control diet ( CD ) . The changes in BP between the preceding CD period and the test diet period ( LNAHK or HC ) were compared with the change between the CD and the OD periods . Of the 56 men and 38 women that completed the OD period , 43 completed the LNAHK diet period and 48 the HC diet period . The mean age was 55.6 + /- 9.9 ( + /-SD ) years . There was a fall in systolic pressure between and the CD and OD [ -1.8 + /- 0.5 mm Hg ( P < 0.001 ) ] . Compared with OD , systolic and diastolic BPs fell during the LNAHK diet period [ -3.5 + /- 1.0 ( P < 0.001 ) and -1.9 + /- 0.7 ( P < 0.05 ) mmHg , respectively ] and increased during the HC diet period [ + 3.1 + /- 0.9 ( P < 0.01 ) and + 0.8 + /- 0.6 ( P = 0.15 ) mm Hg , respectively ] . A self-selected low-sodium , high-potassium diet result ed in a greater fall in BP than a multifaceted OD , confirming the beneficial effect of dietary intervention on BP in a community setting
