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.
