However , it can significantly decrease postintervention and reduction data of FPG , FI , HbA1c , and HOMA-IR .
Heterogeneity was eliminated by subgroup analysis according to baseline BMI .
There was no significant difference in the amelioration of QUICKI between the ITC and control groups .
However , the difference was statistically significant and the heterogeneity was eliminated after subgroup analysis according to intakes of ITC .
Conclusion Supplementation of ITC can ameliorate IR in T2DM , especially in obese T2DM patients , but the effects are controversial in obese patients
Background Insulin resistance ( IR ) is a physiological condition related to type 2 diabetes mellitus ( T2DM ) and obesity , which is associated with high blood insulin and glucose .
Inulin-type carbohydrate ( ITC ) is a kind of fermentable fructan that can reduce glucose and ameliorate IR in an animal model , but the effect in clinical trials is controversial .
Objective The authors conducted a systematic literature review to evaluate the effect of ITC supplementation in ameliorating IR in T2DM and obese patients .
Effects of high performance inulin supplementation on glycemic status and lipid profile in women with type 2 diabetes: a randomized, placebo-controlled clinical trial.
BACKGROUND Type 2 diabetes mellitus , as a noncommunicable disease , is the main public health challenge in the 21st century . The prevalence of diabetes mellitus adjusted for the world population in Iran was 8 % until the year 2010.Lipid levels are considered as important parameters to be evaluated , as high serum lipid levels are often reported as a complication in patients with diabetes mellitus . It is cl aim ed that functional foods may improve complications of diabetes mellitus , so this study was design ed to evaluate the effects of high performance inulin on glycemic status and lipid profile of women with type 2 diabetes . METHODS The study was a r and omized controlled clinical trial . Forty-nine type 2 diabetic females ( fiber intake < 30g/d , 25 < BMI < 35 kg/m2 ) were divided into two groups . Patients in the intervention group ( n=24 ) received 10g/d inulin and patients in the control group ( n=25 ) received 10g/d maltodextrin for 8 weeks .  Glycemic status and lipid profile indices were measured pre and post intervention . Data were analyzed using SPSS software ( verision11.5 ) . Paired , unpaired t-test and ANCOVA were used to compare quantitative variables . RESULTS Supplementation with inulin caused a significant reduction in FBS ( 8.50 % ) , HbA1c ( 10.40 % ) , total cholesterol ( 12.90 % ) , triglyceride ( 23.60 % ) , LDL-c ( 35.30 % ) , LDL-c/HDL-c ratio ( 16.25 % ) and TC/HDL-c ratio ( 25.20 % ) and increased HDL-c ( 19.90 % ) . The changes for the control group parameters were not significant at the end of study . CONCLUSION Inulin may help to control diabetes and its complications via improving glycemic and lipid parameters
However , it can significantly decrease postintervention and reduction data of FPG , FI , HbA1c , and HOMA-IR .
Heterogeneity was eliminated by subgroup analysis according to baseline BMI .
There was no significant difference in the amelioration of QUICKI between the ITC and control groups .
