The Acute Effect of Soluble Dietary Fibre-Enriched Pudding Products on Glycemic and Insulinemic Response in Adults at Risk for Type 2 Diabetes

Abstract

Type 2 Diabetes (T2D) is a chronic loss of the ability to regulate blood glucose, therefore dietary interventions capable of modulating glycemic response are rationalized. A randomized, double-blinded, crossover study was conducted to investigate effects of soluble dietary fibres (DF) (yellow mustard mucilage (YMM), fenugreek gum (FG), flaxseed mucilage (FM)) added to pudding on acute postprandial glycemic response in adults (n=15) at risk for T2D. Results showed significant time by treatment interactions for glucose and insulin, with the soluble DF puddings being lower than the control at some time points. Peak glucose and insulin were also significantly lower with all soluble DF puddings compared to control, although 2-hour incremental area under the curves did not differ. Therefore, YMM, FG and FM have the ability to alter glycemic response in individuals at risk for T2D, suggesting their potential as dietary strategies for individuals who could benefit from alterations in glycemic response.
