The effect of arabinose on sucrose-induced glycemic response and glycemic kinetics as measured by a dual stable isotope methodology

INTERVENTION: Two test days in random order: 1) Drink containing sucrose; 2) Drink containing sucrose + L‐arabinose Both drinks will contain a sucrose‐(13C‐glucose) tracer. There will be a continuous infusion of 2H‐glucose during both tests. CONDITION: Glucose metabolism , Glycemic control ; ; PRIMARY OUTCOME: Total rate of glucose appearance (RaT); ; Exogenous rate of glucose appearance (RaE); ; Total rate of glucose disappearance (RdT); ; Exogenous rate of glucose disappearance (RdE); ; Plasma glucose concentration; ; Plasma insulin concentration SECONDARY OUTCOME: Plasma FFA and glycerol concentrations ; ; Whole‐body carbohydrate and fat oxidation rates INCLUSION CRITERIA: ‐ Male/Female ‐ Aged 18 – 35 y inclusive ‐ BMI 18.5 – 25.0 kg/m2 inclusive ‐ Healthy ‐ Recreationally active (participating in recreational sports activities = 3 times per week)
