Effects of juices enriched with xanthan and β-glucan on the glycemic response and satiety of healthy men.

This study compared the effects of 3 palatable juices enriched with different polysaccharides with a control nonenriched juice on glucose and insulin responses as well as on appetite sensations and determined whether the polysaccharide-induced viscosity contributed to the effects of enriched juices on these variables. Using a randomized crossover design, 14 healthy male subjects consumed 4 juices: 3 juices were enriched with either xanthan gum, β-glucan, or a mix of xanthan gum and β-glucan, and the control juice had no added polysaccharides. Viscosity was measured at a shear rate of 30 s(-1), which represented an approximation of the viscosity in the gastrointestinal tract.
