Moreover , subgroup analyses suggested that the effects of glycemic control were significantly influenced by the sex of the subjects and the type and the method of intake of ITF .
Conclusions Our analyses confirmed that these four main glycemic indicators were significantly reduced by ITF supplementation , particularly in the prediabetes and T2DM population .
Evidence supports that reasonable administration of ITF supplementation may have potential clinical value as an adjuvant therapy for prediabetes and T2DM management .
Background Currently , many clinical trials have shown that inulin-type fructans ( ITF ) supplementation is associated with glycemic control ; nevertheless , the results are inconclusive .
The aim of this meta- analysis of r and omized controlled trials was to assess the effects of ITF supplementation on glycemic control .
Replacement of glycaemic carbohydrates by inulin-type fructans from chicory (oligofructose, inulin) reduces the postprandial blood glucose and insulin response to foods: report of two double-blind, randomized, controlled trials
Purpose Inulin-type fructans are recognized as prebiotic dietary fibres and classified as non-digestible carbohydrates that do not contribute to glycaemia . The aim of the present studies was to investigate the glycaemic response ( GR ) and insulinaemic response ( IR ) to foods in which sucrose was partially replaced by inulin or oligofructose from chicory . Methods In a double-blind , r and omized , controlled cross-over design , 40–42 healthy adults consumed a yogurt drink containing oligofructose or fruit jelly containing inulin and the respective full-sugar variants .  Capillary blood glucose and insulin were measured in fasted participants and at 15 , 30 , 45 , 60 , 90 , and 120 min after starting to drink/eat . For each test food , the incremental area under the curve ( iAUC ) for glucose and insulin was calculated and the GR and IR determined . Results Consumption of a yogurt drink with oligofructose which was 20 % reduced in sugars significantly lowered the glycaemic response compared to the full-sugar reference ( iAUC120min 31.9 and 37.3 mmol/L/min , respectively ; p < 0.05 ) . A fruit jelly made with inulin and containing 30 % less sugars than the full-sugar variant likewise result ed in a significantly reduced blood glucose response ( iAUC120min 53.7 and 63.7 mmol/L/min , respectively ; p < 0.05 ) . In both studies , the postpr and ial insulin response was lowered in parallel ( p < 0.05 ) . The reduction of postpr and ial glycaemia was positively correlated to the proportion of sugars replaced by inulin-type fructans ( p < 0.001 ) . Conclusions In conclusion , the studies confirmed that substitution of glycaemic sugars by inulin or oligofructose from chicory may be an effective strategy to reduce the postpr and ial blood glucose response to foods
