Following the fasting samples, volunteers will consume the test meals. Further blood samples will be collected at 15, 30, 45, 60, 90, 120, 150, 180 minutes after the ingestion of test meal. These samples will be used to analyses for whole capillary blood glucose. At every 30 minute interval, samples will be collected for analysis of capillary plasma insulin.
