Resistant dextrin, as a prebiotic, improves insulin resistance and inflammation in women with type 2 diabetes: a randomised controlled clinical trial.
Improvement of insulin resistance and inflammation is a basic strategy in the management of type 2 diabetes . There is limited evidence that prebiotics improve insulin resistance and inflammation . However , the ameliorating effect of resistant dextrin , as a prebiotic , on insulin resistance and inflammation in patients with type 2 diabetes has not been investigated so far . Therefore , the present study aim ed to examine the effects of resistant dextrin on insulin resistance and inflammation in type 2 diabetic patients . In a r and omised controlled clinical trial , fifty-five women with type 2 diabetes were assigned to two groups : the intervention group ( n 30 ) and the control group ( n 25 ) . The intervention group received a daily supplement of 10 g resistant dextrin and the control group received a similar amount of maltodextrin as placebo for 8 weeks . Fasting plasma glucose ( FPG ) , HbA1c , insulin , high-sensitivity C-reactive protein ( hs-CRP ) , IL-6 , TNF-α , malondialdehyde ( MDA ) and serum endotoxin concentrations were measured before and after the intervention . Data were analysed using SPSS ( version 13 ) . Paired and unpaired t tests and ANCOVA were used to compare quantitative variables after the intervention . Patients supplemented with resistant dextrin exhibited a significant decrease in fasting insulin ( 20.1 pmol/l , 22.8 % ) , homeostasis model assessment of insulin resistance ( 1.3 , 24.9 % ) , quantitative insulin sensitivity check index ( 0.2 , 7.2 % ) , IL-6 ( 1.4 pg/ml , 28.4 % ) , TNF-α ( 5.4 pg/ml , 18.8 % ) , MDA ( 1.2 nmol/ml , 25.6 % ) and endotoxin ( 6.2 endotoxin units/ml , 17.8 % ) concentrations than those supplemented with maltodextrin ( P < 0.05 ) . Decreases in FPG ( 0.05 mmol/l , 0.6 % ) , HbA1c ( 0.5 % , 9.6 % ) and hs-CRP ( 2.7 ng/ml , 35.1 % ) concentrations in the resistant dextrin group were not significant when compared with the maltodextrin group . In conclusion , resistant dextrin supplementation can modulate inflammation and improve insulin resistance in women with type 2 diabetes
