Primary Outcome Measures
NameTimeMethod
Glycemic index0, 15, 30, 45, 60, 90, 120 min

The glycemic index is calculated with the incremental area under the curve of the glycemic response 7 time points ( 0 , 15 , 30, 45 , 60, 90 , 120 min) to 50 g intake carbohydrate food test food and reference

Secondary Outcome Measures
NameTimeMethod
Glucose metabolism related parametersday 1, 8, 15, 22, 29

glucose and insulin assessed in 7 point curves

satiety hunger assessment (visual analogue scale)just before taking the product, just after taking the product, 30, 60 , 90, 120, 180, 240 min and 260 min after taking the product)

visual analogue scale to assessment satiety and hunger will be picked up in 9 time points to calculate the area under the curve to get a score
