Brief summary: A carbohydrate adjusted liquid formula (Inslow) using palatinose as the major carbohydrate (\>50%) was devised. Consumption Inslow for a long term (3-5 months) is reported to improve glycemic control by reducing the postprandial plasma glucose levels in diabetes and impaired glucose-tolerant subjects (IGT). The present study intends to understand the mechanism on postprandial glycemic responses.

Detailed description: The test enteral nutrition formula (Inslow) and the standard balanced formula (Meibalance) were administered in a randomized crossover design to 11 healthy people, 13 IGT and 12 type-2 diabetes, judged by the postprandial state after in taking the two test meals in a random order with a washout period of one week. On the day prior to the test day, subjects were asked to stay at the same facility and to take the same supper with 450 kcal controlled, after 21:00 with only water allowed as ad libitum and not do any exercise. Each participant was taken a fasting blood sample, and then requested to consume one of is energetic test meals (200 kcal per serving) Inslow or standard balanced formula at 7:00 AM. Subsequent blood samples were collected at 30,60,90,and 120 min after meal consumption. The plasma concentrations of glucose, insulin, and free fatty acids were measured for each blood sample. Plasma glucose was measured by hexokinase method, plasma insulin by serum radioimmunoassay method and plasma free fatty acid by enzyme chemical method.Routine blood test and biochemical test were performed using the same blood sample only at fasting stage,including RBC, WBC, TP, ALP, T-Cho, etc., to confirm the status of each subject. Collected blood was applied to analyses at Shanghai Meizhong Clinical Measurement Centre. The enteral nutrition meal Inslow was designed by palatinose, dextrin and fiber as carbohydrate for 56%,23% and 15%, respectively. The standard balanced meal was included dextrin as the main carbohydrate for 85%, together with sugar and fiber.

Eligibility criteria: Inclusion Criteria:
