Methods of Quantifying the Glycemic Index of Raisins in Three Populations

The purpose of this study is to test the hypothesis that differences in glycemic index (GI) calculations [area under the curve (AUC), baseline adjusted, and the excursion method] exist among sedentary (S), athlete (A), and pre-diabetic (P) populations. The GI of raisins is determined in the three groups according to standardized methodology that is based on the calculation of AUC. In addition, two other methods (base-line adjusted and the excursion method) are evaluated. In the S group, both baseline adjusted and excursion result in higher GI values as compared to AUC, thus supporting the hypothesis. In addition, the P group have significantly higher baseline adjusted GI when compared to AUC. Considering the significant differences detected among computation techniques in S and P groups, overall time of glucose elevation may be an important factor. However, for the A group, a calculation technique incorporating time may not be as critical.
