“…Estimates of GI and GL ranged from a mean GI of 40-54 for the lower-GI groups to 53-86 for the higher-GI groups and a mean GL of w50 g/1000 kcal for lower GL groups compared with 75-120 g/1000 kcal for the higher GL groups (Table 1). Two studies reported GI as percentages, but these were not transformed (35,40). The median difference in GI within each study was 10 units, whereas the median difference in GL was 34 units.…”

Background: High blood pressure is a strong risk factor for cardiovascular disease. Objective: The aim of this study was to determine the associations of dietary glycemic index (GI) and glycemic load (GL) with systolic blood pressure (SBP) and diastolic blood pressure (DBP) in healthy individuals. Design: A systematic review and meta-analysis of randomized controlled trials (RCTs) was carried out. Databases were searched for eligible RCTs in 2 phases. MEDLINE, Embase, CAB Abstracts, BIOSIS, ISI Web of Science, and the Cochrane Library were searched from January 1990 to December 2009. An updated search was undertaken with the use of MEDLINE and Embase from January 2010 to September 2016. Trials were included if they reported authordefined high-and low-GI or -GL diets and blood pressure, were of $6 wk duration, and comprised healthy participants without chronic conditions. Data were extracted and analyzed with the use of Stata statistical software. Pooled estimates and 95% CIs were calculated with the use of weighted mean differences and random-effects models. Results: Data were extracted from 14 trials comprising 1097 participants. Thirteen trials provided information on differences in GI between control and intervention arms. A median reduction in GI of 10 units reduced the overall pooled estimates for SBP and DBP by 1.1 mm Hg (95% CI: 20.3, 2.5 mm Hg; P = 0.11) and 1.3 mm Hg (95% CI: 0.2 mm Hg, 2.3; P = 0.02), respectively. Nine trials reported information on differences in GL between arms. A median reduction in GL of 28 units reduced the overall pooled estimates for SBP and DBP by 2.0 mm Hg (95% CI: 0.2, 3.8 mm Hg; P = 0.03) and 1.4 mm Hg (95% CI: 0.1, 2.6 mm Hg; P = 0.03), respectively.

“…Venn et al [34] conducted an 18-month randomized controlled trial study in 18 overweight volunteers in New Zealand. Diets were based on the guidelines published by the National Heart Foundation of New Zealand, which included a recommendation to eat at least 6 servings of breads and cereals each day.…”

“…Four randomised controlled trials were identified that presented evidence on dietary fibre in relation to blood glucose, all of which were included in a meta-analysis (Aller et al, 2004;Thompson et al, 2005;Andersson et al, 2007;Olendzki et al, 2009). Two trials were identified in the update search (Venn et al, 2010;Weickert et al, 2011) (Aller et al, 2004;Thompson et al, 2005;Andersson et al, 2007). No further trials were identified in the update search (Cardiometabolic review, diabetes and glycaemia chapter p 273-276).…”
