One thing that has always confused me is how some foods can be defined as both complex carb and high GI, like potatoes. How exactly does this work? I mean, I never have a potato when I have low blood sugar; orange juice raises my blood sugar quicker even though every site I read claims it has a lower GI than potatoes.
I wondered this about orange juice as well. It has always raised by blood sugar the quickest.
Thanks. I'd like to get to the bottom of the GI and understand more how it works - are there individual variations, etc. I do know for sure that I always get pretty fast results from simple sugars like fruit (except for apples and apple juice - they take much longer and don't have near the same effect!). Bananas are very effective at raising my sugars fast as well as oranges and orange juice (they are apparently both a simple sugar and a high GI food whereas oranges and orange juice are classified as moderate in the GI range).
