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 .
The Effect of Dietary Patterns on Estimated Coronary Heart Disease Risk: Results From the Dietary Approaches to Stop Hypertension (DASH) Trial
Background —The Dietary Approaches to Stop Hypertension ( DASH ) diet is recommended in the 2005 US Dietary Guidelines . To underst and the potential benefits of DASH on coronary heart disease ( CHD ) , we applied the Framingham risk equations to calculate 10-year risk of developing CHD using data from the DASH trial . Methods and Results —In the DASH trial , 459 individuals with prehypertension or stage-1 hypertension not taking antihypertensive medication were r and omly assigned to 1 of 3 diets : control , fruits and vegetables ( F/V ) , or DASH ( rich in fruits , vegetables , low-fat dairy , and reduced in fats and cholesterol ) . Weight was held constant . Estimated 10-year CHD risk was the primary outcome of this secondary analysis . Among 436 participants with complete data , mean ( SD ) age was 44.7 ( 10.7 ) years , 51 % were male , and 60 % were African-American .  Median 10-year CHD risk was 0.98 % at baseline and decreased in all groups . Compared with control , the relative risk ratio comparing 8-week with baseline 10-year CHD risk was 0.93 ( 95 % confidence interval , 0.85 to 1.02 ; P=0.12 ) for F/V and 0.82 ( 95 % confidence interval , 0.75 to 0.90 ; P<0.001 ) for DASH . Comparing DASH with F/V , the relative risk ratio was 0.89 ( 95 % confidence interval , 0.81 to 0.97 ; P=0.012 ) . With the exception of an interaction between dietary pattern and race suggesting a greater risk reduction in blacks than whites ( P for interaction=0.038 ) , results were similar across subgroups . Conclusions —Compared with control and F/V , the DASH diet reduced estimated 10-year CHD risk by 18 % and 11 % , respectively . In addition to reducing blood pressure , the DASH diet should substantially reduce the risk of CHD . Clinical Trial Registration —URL : http:// clinical trials.gov . Unique identifier : NCT00000544
