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 .
Chronic consumption of short-chain fructooligosaccharides does not affect basal hepatic glucose production or insulin resistance in type 2 diabetics.
Short-chain fructooligosaccharides ( FOS ) are prebiotics , which escape digestion in the small intestine and are fermented by the colonic microflora into short-chain fatty acids . Recently , we found that the daily consumption of 20 g FOS decreased basal hepatic glucose production in healthy subjects without any effect on insulin-stimulated glucose metabolism . In this study , we evaluated the effects of the chronic ingestion of FOS on plasma lipid and glucose concentrations , hepatic glucose production and insulin resistance in type 2 diabetics . Type 2 diabetic volunteers ( n = 10 ; 6 men , 4 women ) received either 20 g/d FOS or sucrose for 4 wk in a double-blind crossover design . FOS did not modify fasting plasma glucose and insulin concentrations or basal hepatic glucose production . The plasma glucose response to a fixed exogenous insulin bolus did not differ at the end of the two periods . Erythrocyte insulin binding also did not differ . Serum triacylglycerol , total and HDL cholesterol , free fatty acid , apolipoproteins A1 and B and lipoprotein ( a ) concentrations were not modified by the chronic ingestion of FOS . We conclude that 4 wk of 20 g/d of FOS had no effect on glucose and lipid metabolism in type 2 diabetics
