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 .
A low-fat vegan diet and a conventional diabetes diet in the treatment of type 2 diabetes: a randomized, controlled, 74-wk clinical trial.
BACKGROUND Low-fat vegetarian and vegan diets are associated with weight loss , increased insulin sensitivity , and improved cardiovascular health . OBJECTIVE We compared the effects of a low-fat vegan diet and conventional diabetes diet recommendations on glycemia , weight , and plasma lipids . DESIGN Free-living individuals with type 2 diabetes were r and omly assigned to a low-fat vegan diet ( n = 49 ) or a diet following 2003 American Diabetes Association guidelines ( conventional , n = 50 ) for 74 wk . Glycated hemoglobin ( Hb A(1c ) ) and plasma lipids were assessed at weeks 0 , 11 , 22 , 35 , 48 , 61 , and 74 . Weight was measured at weeks 0 , 22 , and 74 . RESULTS Weight loss was significant within each diet group but not significantly different between groups ( -4.4 kg in the vegan group and -3.0 kg in the conventional diet group , P = 0.25 ) and related significantly to Hb A(1c ) changes ( r = 0.50 , P = 0.001 ) . Hb A(1c ) changes from baseline to 74 wk or last available values were -0.34 and -0.14 for vegan and conventional diets , respectively ( P = 0.43 ) . Hb A(1c ) changes from baseline to last available value or last value before any medication adjustment were -0.40 and 0.01 for vegan and conventional diets , respectively ( P = 0.03 ) . In analyses before alterations in lipid-lowering medications , total cholesterol decreased by 20.4 and 6.8 mg/dL in the vegan and conventional diet groups , respectively ( P = 0.01 ) ; LDL cholesterol decreased by 13.5 and 3.4 mg/dL in the vegan and conventional groups , respectively ( P = 0.03 ) . CONCLUSIONS Both diets were associated with sustained reductions in weight and plasma lipid concentrations . In an analysis controlling for medication changes , a low-fat vegan diet appeared to improve glycemia and plasma lipids more than did conventional diabetes diet recommendations . Whether the observed differences provide clinical benefit for the macro- or microvascular complications of diabetes remains to be established .
