 In the morning of each test, a finger-prick capillary blood samples will be collected to determine fasting baseline blood glucose levels. The volunteers will then consume the test solution assigned for that trial. Ten minutes will be allowed for the test solution to be consumed. Over the two hours following the start of each test, finger-prick capillary blood samples were collected at 30, 60, 90, and 120 min. Blood glucose levels will be immediately measured in duplicate using an automated blood glucose analyzer YSI 2300, Yellow Springs, OH. Analysis of the collected sample was repeated if the difference between duplicate samples was greater than 0.1 mmolL. Once the samples were analyzed, the data was entered and the incremental area under the curve was calculated using the trapezoidal model GraphPad v5.0, La Jolla, CA.
