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 .
Effects of pistachio nut supplementation on blood glucose in patients with type 2 diabetes: a randomized crossover trial.
BACKGROUND Diabetes is a chronic , potentially debilitating , and often fatal disease . Dietary strategies to reduce postpr and ial glycemia are important in the prevention and treatment of diabetes . Nuts are rich in mono- and polyunsaturated fatty acids , which may reduce hyperglycemia and improve metabolism . OBJECTIVES To evaluate the effectiveness of pistachio nut supplementation on glycemic and inflammatory measures in patients with type 2 diabetes . METHODS In this double-blind , r and omized , placebo-controlled , crossover trial , 48 diabetic patients were equally assigned to groups A and B. Patients in group A received a snack of 25 g pistachio nuts twice a day for 12 weeks and group B received a control meal without nuts . After 12 weeks of intervention , the patients had an 8-week washout . Then the groups were displaced , and group B received the same amount of pistachios for 12 weeks . RESULTS With respect to the total change in variables over both phases , there was a marked decrease in HbA1c ( -0.4 % ) and fasting blood glucose ( FBG ) concentrations ( -16 mg/dl ) in the pistachio group compared with the control group ( p ≤ 0.001 for both ) . There was no overall significant change in BMI , blood pressure , HOMA-IR , and C-reactive protein ( CRP ) concentrations . Analysis of the two phases separately showed a decrease in FBG by 14 mg/dl and in HbA1c by 0.45 % in the treatment group ( A ) after 12 weeks , while no significant differences were seen in group B ( control group ) . In the second phase , FBG decreased from 151.36 ± 39.22 to 137.28 ± 28.65 mg/dl ( -14 mg/dl ) and HbA1c decreased from 7.42 ± 0.97 to 7.15 ± 0.68 mg/dl ( -0.28 % , p = 0.013 and p = 0.033 , respectively ) in the pistachio group ( B ) . Pistachio consumption reduced systolic blood pressure ( p = 0.007 ) , BMI ( p = 0.011 ) , and CRP ( p = 0.002 ) in patients from the treatment groups , but not insulin resistance . CONCLUSIONS Dietary consumption of pistachio nuts as a snack has beneficial effects on glycemic control , blood pressure , obesity , and inflammation markers in diabetic patients
