Ten healthy, normal-weight adults after 10-14 hours of fasting, consumed 50g available carbohydrates from D-glucose, tested three times, in different visits as reference food; and 50g available carbohydrates from orange juice and mixed fruit juice (consisted of apple, orange, grape, and pomegranate), each tested once, in different visits, along with 300mL water. There was a washout period of at least two days between visits. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min after beverage consumption. The first glucose sample was taken exactly 15min after the first sip of drink.

Ten healthy, normal-weight subjects after 10-14 hours of fasting, consumed 50g glucose diluted in 300ml water, tested three times, in different visits, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120 min.

Glucose solution (50 g) was the reference food (GI = 100%) against which all test foods were compared. Subjects arrived at the laboratory at eight to nine o'clock in the morning after 10-12 h overnight fast. Each subject was fed equivalent 50 g available carbohydrate of test foods or reference food in random order. To minimize day to day variation of glucose tolerance, the reference food was tested in triplicate in each subject. All test and reference foods were served with 250 mL of water. An automatic lancet device and glucometer (calibrated MediSmart Ruby glucose meter with a lancing device, Lilly-PHARMASERV SA, Greece) was used for finger capillary blood samples. Blood samples were taken immediately before the start of the study (0 min) and 15, 30, 45, 60, 90 and 120 min after the start of eating.

Clinically useful change in blood glucose, defined as the restoration of glucose within normal limits during the 2hr glucose tolerance test

Useful change in subjective appetite using visual analogue scales with a score 0 to 10 (given in the form of booklet, one scale per page) at baseline, 15, 30, 45, 60, 90 and 120min. The minimum or maximum score will be evaluated if it is better or worse depending on the appetite variable e.g. hunger, satiety, desire to eat, etc.
