RW — What's the difference between the well known glycemic index (GI) and this insulin index (II) you're referring to?
JB — The popular glycemic index is a measure of the speed at which carbohydrates enter the blood after a meal. A high-glycemic index means that blood sugar rises rapidly in response to a meal while a low-glycemic index means that blood sugar rises very slowly. Traditionally, nutritionists thought that the faster the carbs got into the blood, the bigger the insulin response. So in an attempt to manage insulin, they recommended always eating low-glycemic foods.
However, several studies since have shown that some low glycemic index foods have huge insulin responses! So the correlation between glycemic index and insulin response breaks down with some foods. For example, milk products have a very low glycemic index. But they promote insulin responses parallel to the highest glycemic foods. What's the deal? Well, it appears that there are several other factors that determine insulin release besides carb content and the rate of carb absorption.
This is why the insulin index was generated. This index actually measures insulin response to a food. So rather than assuming insulin response is correlated with carb absorption, these researchers decided to go ahead and measure it. And their results were eye opening!
