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 .
Short-term effects of severe dietary carbohydrate-restriction advice in Type 2 diabetes--a randomized controlled trial.
OBJECTIVE This study sought to examine the effects of a 3-month programme of dietary advice to restrict carbohydrate intake compared with reduced-portion , low-fat advice in obese subjects with poorly controlled Type 2 diabetes . RESEARCH DESIGN AND METHODS One hundred and two patients with Type 2 diabetes were recruited across three centres and r and omly allocated to receive group education and individual dietary advice .  Weight , glycaemic control , lipids and blood pressure were assessed at baseline and 3 months . Dietary quality was assessed at the end of study . RESULTS Weight loss was greater in the low-carbohydrate ( LC ) group ( -3.55 + /- 0.63 , mean + /- sem ) vs. -0.92 + /- 0.40 kg , P = 0.001 ) and cholesterol : high-density lipoprotein ( HDL ) ratio improved ( -0.48 + /- 0.11 vs. -0.10 + /- 0.10 , P = 0.01 ) . However , relative saturated fat intake was greater ( 13.9 + /- 0.71 vs. 11.0 + /- 0.47 % of dietary intake , P < 0.001 ) , although absolute intakes were moderate . CONCLUSIONS Carbohydrate restriction was an effective method of achieving short-term weight loss compared with st and ard advice , but this was at the expense of an increase in relative saturated fat intake
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 .
