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 .
Can the Mediterranean diet lower HbA1c in type 2 diabetes? Results from a randomized cross-over study.
BACKGROUND AND AIMS To investigate the impact of a diet modeled on the traditional Cretan Mediterranean diet on metabolic control and vascular risk in type 2 diabetes . METHODS AND RESULTS Twenty-seven subjects ( 47 - 77 yrs ) with type 2 diabetes were r and omly assigned to consume either the intervention diet ad libitum or their usual diet for 12 weeks and then cross over to the alternate diet . Most of the meals and staple foods for the intervention diet were provided . Lipids , glycemic variables , blood pressure , homocysteine , C-reactive protein , plasma carotenoids and body composition ( anthropometry and dual energy X-ray absorptiometry ) were assessed at baseline , and at the end of both diet periods . Dietary adherence was monitored using plasma carotenoid and fatty acid ( FA ) analysis , complemented by diet diaries . Compared with usual diet , on the ad libitum Mediterranean intervention diet glycosylated haemoglobin fell from 7.1 % ( 95 % CI : 6.5 - 7.7 ) to 6.8 % ( 95 % CI : 6.3 - 7.3 ) ( p=0.012 ) and diet quality improved significantly [ plant : animal ( g/day ) food ratio increased from 1.3 ( 95 % CI : 1.1 - 1.5 ) to 5.4 ( 95 % CI : 4.3 - 6.6 ) ( p<0.001 ) ] , plasma lycopene and lutein/zeaxanthin increased ( 36 % and 25 % , respectively ) , plasma saturated and trans FAs decreased , and monounsaturated FAs increased . CONCLUSION A traditional moderate-fat Mediterranean diet improves glycemic control and diet quality in men and women with well-controlled type 2 diabetes , without adverse effects on weight
