Hello,
From what I have read, the glycemic index is a limited tool because it doesn't take the amount of ingested carbs into account, hence why the glycemic load was created.
But then I read an example that threw me: a serving of 10g with an GI of 100 is equivalent to a serving of 100 g with a GI of 10, since they have the same GL of 10.
So my question is: how do we know that blood glucose levels will rise constantly? Is glucose absorption really constant and unlimited? I don't think it is the case with other nutrients, is it?
I mean, what if they rise constantly with the first 90g of GI=10 food, and then the rise slows down with the final 10 grams (because of some kind of saturation for example, although I haven't studied glucose metabolism yet), which would cancel the equivalence suggested by GL calculation? Or the other way round? What if it increases 'normally' at first, and then more and more as the intake gets bigger?
Is it an established fact that blood glucose increase is directly proportional to quantity x GI ?
I hope my question is clear...
Thanks!
