For most comparisons , the credibility of evidence was rated very low to moderate , with the exception for the DASH vs. the low-fat dietary approach for which the quality of evidence was rated high .
Conclusion : The present network meta- analysis suggests that the DASH dietary approach might be the most effective dietary measure to reduce blood pressure among hypertensive and pre-hypertensive patients based on high quality evidence
ABSTRACT Background : Pairwise meta-analyses have shown beneficial effects of individual dietary approaches on blood pressure but their comparative effects have not been established .
Objective : Therefore we performed a systematic review of different dietary intervention trials and estimated the aggregate blood pressure effects through network meta- analysis including hypertensive and pre-hypertensive patients .
A randomized clinical trial comparing low-glycemic index versus ADA dietary education among individuals with type 2 diabetes.
OBJECTIVE We compared the effects of a low glycemic index ( GI ) diet with the American Diabetes Association ( ADA ) diet on glycosylated hemoglobin ( HbA1c ) among individuals with type 2 diabetes . METHODS Forty individuals with poorly controlled type 2 diabetes were r and omized to a low-GI or an ADA diet . The intervention , consisting of eight educational sessions ( monthly for the first 6 mo and then at months 8 and 10 ) , focused on a low-GI or an ADA diet .  Data on demographics , diet , physical activity , psychosocial factors , and diabetes medication use were assessed at baseline and 6 and 12 mo . Generalized linear mixed models were used to compare the two groups on HbA1c , diabetic medication use , blood lipids , weight , diet , and physical activity .  RESULTS Participants ( 53 % female , mean age 53.5 y ) were predominantly white with a mean body mass index of 35.8 kg/m(2 ) . Although both interventions achieved similar reductions in mean HbA1c at 6 mo and 12 mo , the low-GI diet group was less likely to add or increase dosage of diabetic medications ( odds ratio 0.26 , P = 0.01 ) . Improvements in high-density lipoprotein cholesterol , triacylglycerols , and weight loss were similar between groups . CONCLUSION Compared with the ADA diet , the low-GI diet achieved equivalent control of HbA1c using less diabetic medication . Despite its limited size , this trial suggests that a low-GI diet is a viable alternative to the ADA diet . Findings should be evaluated in a larger r and omized controlled trial
For most comparisons , the credibility of evidence was rated very low to moderate , with the exception for the DASH vs. the low-fat dietary approach for which the quality of evidence was rated high .
