So since the banana is lower it might work but not as well. Thanks for that info.
Now, about that other thing you wrote. Raisins not providing a fast spike. That's kind of a subjective relative comment that I'd like to understand better. What did you mean? Or rather what would you consider as another nutrient that would provide a faster spike.
I don't necessarily need a fast spike so much as I want an increase (in blood sugar) that will endure about an hour of intense training.
I suggest you google the glycemic index, because IMO it is a useful concept. Personally in my everyday eating as well as on long bicycle rides I employ it, and go for low glycemic foods. I would ask though, and I don't know the answer, would not the body's homeostatic mechanisms mediated by the various hormones kick in during prolonged, high intensity workouts and essentially overide the immediately preceding food intake, e.g. by glycogen release, muscle uptake, etc.?
