Not Applicable

Completed

• Conditions: Diabetes
• Interventions: Other: Glucose Reference 1; Other: Glucose Reference 2; Other: Glucose Reference 3; Other: Wholegrain Penne; Other: Semolina Penne; Other: Semolina Spaghetti; Other: Wholegrain Spaghetti; Other: Asian Noodles; Other: Jasmine Rice

• Registration Number: NCT03646812
• Lead Sponsor: Clinical Nutrition Research Centre, Singapore

Brief Summary

The aim of the study is to determine the glycaemic and insulinaemic index of pasta products and local foods. It is hypothesized that different pasta cuts and wholegrain composition of pasta and local foods have different GI depending on the nature of the carbohydrate content and the food structure within each food.

Detailed Description

There will be a total of 9 test sessions and each session will last up to 3.5 hours. The order of sessions will be determined with an online randomizer. 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.
