• Registration Number: NCT04228341
• Lead Sponsor: Clinical Nutrition Research Centre, Singapore

Brief Summary

To investigate the effects of rice polishing on glycaemic and insulinaemic response in healthy Chinese male volunteers.

Detailed Description

There will be a total of 8 test session. Each session will last for 3.5 hours. At each test session, volunteers will be served with test meal and blood will be collected. After an overnight fast, subjects will visit the research center. Two fasting capillary blood samples will be collected via fingerprick. Following the fasting samples, subject 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.
