Determination of the Postprandial Responses to Two Cereal Foods Differing by Their SDS Content Consumed Alone.

This study aimed at determining the 4-hours postprandial blood glucose and insulin responses to the ingestion of cereal product differing by their SDS content. It is a laboratory-based research study with an open cross-over design, including 20 healthy non-smoking voluntary subjects, aged from 18 to 45 years. 2 test sessions per subject are included in the study. Foods are consumed in a random order according to a randomisation list.

Not more than 10% of the subjects will be of Asian or Asian Indian descent. The remaining subjects will be from other ethnic groups except from Australian Aborigines.
• Healthy subjects with:

• Normal glucose tolerance (fasting blood glucose < 6.0 mmol/L during the first test session and results of oral glucose tolerance test conducted within the last 30 days within recommendations (fasting blood glucose < 6.0 mmol/L, 120 minute glucose < 8.9 mmol/L))
