The effect of fiber-rich milk and equi-carbohydrate snack on glycemic and insulin response and satiety feeling
Abstract: Additional dietary
fibers which can decrease the glycemic response by slowing down digestion
whilst maintaining the available carbohydrate content is one approach of
healthy diet. This study aimed to compare post-prandial glycemic and insulin
response, hunger and satiety feeling after consuming fiber-rich milk compare
with equi-carbohydrate food as morning snack in healthy adults.
Methods: Cross-over study was conducted on 12 healthy subjects who
fulfilled the criteria. Each test food
was given after consuming standard breakfast. Venous blood samples for insulin
and glucose level were taken before consuming test food, at 30, 60, 120, and
180 minutes after, and plotted against time to generate a curve. Hunger and
satiety assessments were taken by visual analog scale (VAS) after each blood
sampling.
Results: In average, age was 30.8+4.3 years old, body mass index was
20.6±1.6 kg/m2. Seven of twelve subjects were females. There were significantly
differences in postprandial glycemic response (p<0.001), insulin response
(p=0.045) and hunger feeling (p=0.021) between the two foods. However,
postprandial satiety feelings were not different significantly (p=0.357). The
glycemic response area under the curve of fiber-rich milk was significantly
lower than the equi-carbohydrate snack (p=0.010).
Conclusion: Differences in glycemic and insulin response, and hunger
feeling between two test foods, suggesting that fiber-rich milk can be used as
an alternative snack for healthy adults. Further study is needed for the use of
fiber-rich milk as an alternative snack for pre-diabetic patients.
