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 .
Effects of the Dietary Approaches to Stop Hypertension Diet Alone and in Combination With Exercise and Caloric Restriction on Insulin Sensitivity and Lipids
This study examined the effects of the Dietary Approaches to Stop Hypertension ( DASH ) diet on insulin sensitivity and lipids . In a r and omized control trial , 144 overweight ( body mass index : 25 to 40 ) men ( n=47 ) and women ( n=97 ) with high blood pressure ( 130 to 159/85 to 99 mm Hg ) were r and omly assigned to one of the following groups : ( 1 ) DASH diet alone ; ( 2 ) DASH diet with aerobic exercise and caloric restriction ; or ( 3 ) usual diet controls ( UC )  . Body composition , fitness , insulin sensitivity , and fasting lipids were measured before and after 4 months of treatment . Insulin sensitivity was estimated on the basis of glucose and insulin levels in the fasting state and after an oral glucose load . Participants in the DASH diet with aerobic exercise and caloric restriction condition lost weight ( −8.7 kg [ 95 % CI : −2.0 to −9.7 kg ] ) and exhibited a significant increase in aerobic capacity , whereas the DASH diet alone and UC participants maintained their weight ( −0.3 kg [ 95 % CI : −1.2 to 0.5 kg ] and + 0.9 kg [ 95 % CI : 0.0 to 1.7 kg ] , respectively ) and had no improvement in exercise capacity . DASH diet with aerobic exercise and caloric restriction demonstrated lower glucose levels after the oral glucose load , improved insulin sensitivity , and lower total cholesterol and triglycerides compared with both DASH diet alone and UC , as well as lower fasting glucose and low-density lipoprotein cholesterol compared with UC . DASH diet alone participants generally did not differ from UC in these measures . Combining the DASH diet with exercise and weight loss result ed in significant improvements in insulin sensitivity and lipids . Despite clinical ly significant reductions in blood pressure , the DASH diet alone , without caloric restriction or exercise , result ed in minimal improvements in insulin sensitivity or lipids
