• Conditions: Diabetes
• Interventions: Other: Wheat Yellow Noodle; Other: Rice Roll with resistant starch; Other: Sucrose Jelly; Other: Glucose Reference 2; Other: Glucose Reference 3; Other: Glucose Reference 1; Other: Beta-glucan yellow Noodle; Other: Rice Roll; Other: Isomaltulose Jelly

• Registration Number: NCT03706378
• Lead Sponsor: Clinical Nutrition Research Centre, Singapore

Brief Summary

The study specifically aims to determine glycemic and insulinemic response of added low GI ingredients, beta-glucan, resistant starch and isomaltulose to foods.

Detailed Description

There will be a total of 9 test sessions and each session will last up to 3 hours. At each test session, the following procedures will be performed: two finger-prick blood samples, five minutes apart to measure baseline blood glucose and insulin concentrations. Subject will be served the test food and to consume within15 minutes. Following the test meal, blood samples will be collected at the following time points: 15, 30, 45, 60, 90, 120, 150 and 180min for glucose measurements and insulin measurements will be collected at 30, 60, 90, 120, 150 and 180min.
