Multi pIe-regression analysis of the individual results showed that the glycemic response was a significant predictor of the insulin response, but it accounted for only 23\% of the variability in insulinemia. The macronutrients (protein or fat, water, sugar, and starch) were also significant predictors, but together ac counted for only another 10\% of the variability of the insulin responses. Thus, we can explain only 33\% of the variation of the insulin responses to the 38 foods under examination. The low R2 value indicates that the macronutrient composition of foods has relatively limited power for predicting the extent of postprandial insulinemia. The rate of starch digestion, the amount of rapidly available glucose and resistant starch, the degree ofosmolality, the viscosity ofthe gut's contents, and the rate of gastric emptying must be other important factors influ encing the degree of postprandial insulin secretion.
