The participants will arrive at the laboratory between 8:30-9 am following a 10 hour overnight fast. They will be instructed not to partake in intense level sports and avoid alcohol consumption on the evening prior to a test session. Following a 10 minute rest two blood samples will be obtained five minutes apart for determining baseline blood glucose levels. If the two baseline blood glucose values are far apart a further 1-2 blood samples may be taken until two stable values are obtained. The study session will be terminated if stable values cannot be obtained or if baseline blood glucose levels are above 6 mmol/L. After obtaining acceptable baseline blood glucose values they will be given either the standard or test food to consume. They will be asked to consume the drink at a comfortable pace within 10 minutes. Further blood samples will be obtained at 15, 30, 45, 60, 90, 120, 150 and 180 minutes for blood glucose measurements. Mandatory sampling will be carried out up to 120 minutes. If the blood glucose level has not reached baseline levels by the end of 120 minutes further samples may be taken at 150 and 180 minutes. During the entire testing period the participants will be instructed to remain rested and in the laboratory.
