would it be possible to slow the absorption of hi gi carbs like macaronee (sp?) and cheese with a good serving of broccoli or something high in fiber?

Fiber can slow transit time and has the potential to block some of the carbs from being absorbed. However, the GI of the carbs wont change, so what is absorbed will still reach the blood stream at a fast rate.

that is a good question, now to my knowledge the addition of either protein or fat will lower the GI of something which has a high GI, ala the PB on a rice cake, but as far as fiber goes, I do not know, it would make sense that it would also, being that it like the others slows digestion, but I cant say for sure

The glycaemic index of a meal is the average of the indices of all its components so adding something high in fibre will, in essence, lower the GI... but you also have to make sure you are eating foods that have a low glycaemic load (that is, how MUCH carbohydrate you are eating overall...).

These articles might help....
