Hello
Its not so much *sugar* per se (which actually doesn't have as high a GI as you might think), but how it is broken down when it is digested.
White french baguette bread, for instance has a GI score of 95 (its out of 100 - 100 being that the food you've eaten goes into your bloodstream instantaneously - the lower the score the better basically)
1 teaspoon of sucrose has a GI score of 65, whilst 30g of rice krispies has a score of 82.
So I personally would avoid the rice krispies and eat something like all-bran, coming in at 42 for 40g.
Full fat milk has a GI score of 27, which is pretty low obviously.
So as you can see, its not that obvious which are high sugar foods and which aren't. Its about how the sugar/carbohydrate molecules are broken down in the gut, and how fast the sugar can enter your bloodstream. So milk, for example, yes has sugar in it, but for the sugar to be available in your bloodstream the milk sugar has to have been broken down first, and that doesn't happen so fast - its a complicated molecule.
White bread, OTOH, has a simple starch molecule and needs only one or two steps to break the chain up and get into your bloodstream.
If you want to read more try "the glucose revolution" or something like that.
Kind regards
Meri
