The glycemic index can be misleading because fat content can lower it, and foods are rarely eaten in isolation.

“For instance, Ice cream has a lower glycemic index, provided its ice cream that includes fat, which I hope it would, 'cause that's the good tasting ice cream, in my opinion, compared to something like mangoes or table sugar, right? So the glycemic index is not something to hold holy, in most cases, because most people are not ingesting foods in isolation.”
