Food Containing Resistant Starch Type 4 and Postprandial Glycemic Response

Completed · Not applicable

Conditions studied: Healthy

In brief

The primary objective of the study is to determine if resistant starch reduces the 2 hour glycemic response as measured by positive incremental area under the blood glucose response curve (Positive iAUC- ignores area below fasting). Secondary endpoints include insulin iAUC, glucose and insulin net incremental AUC (net iAUC), time point of peak rise (T max) of glucose and insulin, and glucose and insulin concentrations at each time point (C max).
