Favourable effects of the Dietary Approaches to Stop Hypertension diet on glucose tolerance and lipid profiles in gestational diabetes: a randomised clinical trial.
Although gestational diabetes mellitus ( GDM ) is associated with an increased risk of maternal and neonatal morbidity , there is no consensus as to the optimal approach of nutritional management in these patients . The present study was design ed to assess the effect of the Dietary Approaches to Stop Hypertension ( DASH ) eating plan on glucose tolerance and lipid profiles of pregnant women with GDM . The present r and omised controlled clinical trial was performed among thirty-four women diagnosed with GDM at 24 - 28 weeks of gestation . Subjects were r and omly assigned to consume either the control diet ( n 17 ) or the DASH eating pattern ( n 17 ) for 4 weeks . The control diet was design ed to contain 45 - 55 % carbohydrates , 15 - 20 % protein and 25 - 30 % total fat . The macronutrient composition of the DASH diet was similar to the control diet ; however , the DASH diet was rich in fruits , vegetables , whole grains and low-fat dairy products , and contained lower amounts of saturated fats , cholesterol and refined grains with a total of 2400 mg Na/d . Fasting blood sample s were taken at baseline and after 4 weeks of intervention to measure fasting plasma glucose , glycated Hb ( HbA1c ) and lipid profiles . Participants underwent a 3 h oral glucose tolerance tests and blood sample s were collected at 60 , 120 and 180 min to measure plasma glucose levels . Adherence to the DASH eating pattern , compared with the control diet , result ed in improved glucose tolerance such that plasma glucose levels reduced at 60 ( 21·86 v. 20·45 mmol/l , Pgroup = 0·02 ) , 120 ( 22·3 v. 0·2 mmol/l , Pgroup = 0·001 ) and 180 min ( 21·7 v. 0·22 mmol/l , Pgroup = 0·002 ) after the glucose load . Decreased HbA1c levels ( 20·2 v. 0·05 % , Pgroup = 0·001 ) was also seen in the DASH group compared with the control group . Mean changes for serum total ( 20·42 v. 0·31 mmol/l , Pgroup = 0·01 ) and LDL-cholesterol ( 20·47 v. 0·22 mmol/l , Pgroup = 0·005 ) , TAG ( 20·17 v. 0·34 mmol/l , Pgroup = 0·01 ) and total : HDL-cholesterol ratio ( 20·6 ( SD 0·9 ) v. 0·3 ( SD 0·8 ) , Pgroup = 0·008 ) were significantly different between the two diets . Additionally , consumption of the DASH diet favourably influenced systolic blood pressure ( 22·6 v. 1·7 mmHg , Pgroup = 0·001 ) . Mean changes of fasting plasma glucose ( 20·29 v. 0·15 mmol/l , Pgroup = 0·09 ) were nonsignificant comparing the DASH diet with the control diet . In conclusion , consumption of the DASH eating pattern for 4 weeks among pregnant women with GDM result ed in beneficial effects on glucose tolerance and lipid profiles compared with the control diet
