According to the network meta- analysis the Mediterranean diet is the most effective and efficacious dietary approach to improve glycaemic control in type 2 diabetes patients
The aim of the present study is to assess the comparative efficacy of different dietary approaches on glycaemic control in patients with type 2 diabetes mellitus using a systematic review of the literature .
Effect of Lowering the Glycemic Load With Canola Oil on Glycemic Control and Cardiovascular Risk Factors: A Randomized Controlled Trial
OBJECTIVE Despite their independent cardiovascular disease ( CVD ) advantages , effects of α-linolenic acid ( ALA ) , monounsaturated fatty acid ( MUFA ) , and low-glycemic-load ( GL ) diets have not been assessed in combination . We therefore determined the combined effect of ALA , MUFA , and low GL on glycemic control and CVD risk factors in type 2 diabetes . RESEARCH DESIGN AND METHODS The study was a parallel design , r and omized trial wherein each 3-month treatment was conducted in a Canadian academic center between March 2011 and September 2012 and involved 141 participants with type 2 diabetes ( HbA1c 6.5%–8.5 % [ 48–69 mmol/mol ] ) treated with oral antihyperglycemic agents . Participants were provided with dietary advice on either a low-GL diet with ALA and MUFA given as a canola oil – enriched bread supplement ( 31 g canola oil per 2,000 kcal ) ( test ) or a whole-grain diet with a whole-wheat bread supplement ( control ) . The primary outcome was HbA1c change . Secondary outcomes included calculated Framingham CVD risk score and reactive hyperemia index ( RHI ) ratio . RESULTS Seventy-nine percent of the test group and 90 % of the control group completed the trial . The test diet reduction in HbA1c units of −0.47 % ( −5.15 mmol/mol ) ( 95 % CI −0.54 % to −0.40 % [ −5.92 to −4.38 mmol/mol ] ) was greater than that for the control diet ( −0.31 % [ −3.44 mmol/mol ] [ 95 % CI −0.38 % to −0.25 % ( −4.17 to −2.71 mmol/mol ) ] , P = 0.002 ) , with the greatest benefit observed in those with higher systolic blood pressure ( SBP ) . Greater reductions were seen in CVD risk score for the test diet , whereas the RHI ratio increased for the control diet . CONCLUSIONS A canola oil – enriched low-GL diet  improved glycemic control in type 2 diabetes , particularly in participants with raised SBP , whereas whole grains improved vascular reactivity
