You Are All Wrong!
The correct order from highest Glycemic Index to lowest Glycemic Index is the following:
Don't worry. I got it wrong too the first time I tried this.
This is a quick chart of the Glycemic Index of sugars:
As you can see, Fructose is smack dab in the middle of the Glycemic Index. Orange juice is literally in the middle with a GI of 52 (out of 100). The sugar that makes Rice Krispies is actually very similar to the sugar found in your glucose tablets, so that's why it's the fastest with a GI of 82.
Bagels come in second with a GI of 72. Bagels are a "branch-chained" starch, which means it kind of looks like a tree (Okay, that's how Gary described it... I'm not making this up). Because enzymes are able to break down more than one sugar molecule at a time, it doesn't take as long to digest. Straight-chained starches take long because you have to break it down one at a time. Potatoes and most breads are pretty high on the GI, with most being over 70 (except for pita bread and rye bread). Legumes and pasta tend to be lower on the GI.
The low-fat yogurt, being lactose, comes in last at 33.
So, if you're low, have a bowl of Rice Krispies by leave out the milk!
Also, coincidentally, dLife just posted a new article all about the Glycemic Index, so you can find out more by reading it.
