Primary Outcome Measures:
  • Change in blood glucose concentration [ Time Frame: several time points after ingestion of test substance ] [ Designated as safety issue: No ]
    Test substances will be given at 0800 hr and blood drawn at several time points up to 5 hours after the meal.


Secondary Outcome Measures:
  • Change in serum insulin concentration [ Time Frame: Several time points after ingestion of test substance ] [ Designated as safety issue: No ]
    Test substances will be given at 0800 hr and blood drawn at several time points up to 5 hours after the meal.

Detailed Description:

Various foods or food substances are given as a test meal. The metabolic response is determined at various times after the administration of the meal (e.g. blood glucose, and other hormones and metabolites).
