I hear people on this site throwing the term 'Glycemic Index' a lot and I'd like to familiarize myself with how the GI of specific foods affect my diet.

For instance, I have recently started eating potato bread instead of white bread and I'd like a way to compare the Glycemic Index of the two to see how the change will affect my current diet.

Is there a particular source that's good for looking up the GI of specific foods (like Wolfram Alpha is for researching nutritional facts)?

NOTE: certain foods don't have any glycemic reaction like chicken, beef, etc. However if you marinade them, you'll have to check out what the GI is on the marinade.

Probably one of the most useful would be this:
