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.

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))
  * Normal laboratory values for various measures of metabolic health (full blood count, gamma-GT, AST, ALT, glucose, TAGs, total cholesterol, HDL-cholesterol, LDL-cholesterol);
  * Normal systolic blood pressure (100-150 mmHg);
  * Normal diastolic blood pressure (60-90 mmHg);
  * Normal resting heart rate (50-90 beats per minutes after 3 minutes rest).

* Able to fast for at least 10 hours the night before each test session
* Able to refrain from eating legumes and drinking alcohol the day before each test session.
* Subject covered by social security or covered by a similar system
