I’ve read that when one drinks a casein solution, it forms a “clot” in the stomach which slows digestion of evrything else in there with it (this may be a model for something more complex, I dunno).
Anyway, my point is - if you were to drink some casein before consuming a high GI food, would this “casein clot” make it comparable to a lower GI food?
I always just assumed this must be the case, but I was wondering what others thought 
The GI and GL index are worthless when it comes to combining foods. No one knows for sure how each food affects others, other than to say adding fiber or fish oil to a meal will reduce the GI. Again though no one knows by how much it will be reduced.

Very interesting, indeed!
the glucose load dose not change, it is simply the total glucose you consume. the comments regarding the GI are accurate.

True.
The amount of sugar and calories will not change, but adding fiber, fat and protein will slow the digestion. Fiber would have the least glycemic/calorie impact. It is even better if the fiber is actually part of the food like an apple! The creators of the glycemic index said in one of their books/articles that it would be too difficult to quantify GI’s of mixed foods becuase the combos and ratios are nearly endless. If you have not already, look into the “glycemic load” it is more pertinent measure of the food amounts that you eat.

True. [/quote]
The glycemic load however is based on amount and GI: [url]http://en.wikipedia.org/wiki/Glycemic_load[/url]
I know we can’t give exact figures when it comes to combining food, however it was just a thought - that someone could add a huge amount of calories by first drinking casein and then chugging something like malto or whatever, but without getting a crazy insulin response… Any more thoughts?

the casein is not very likely to slow the absorption of the maltodextrin much, however, raised amino acid levels in the blood may facilitate nutrient partitioning, chances are you are still getting an insulin spike, it may be a tad lower, or could be higher, hard to say until you run a tightly controlled experiment.

Interesting… Thanks for the reply.
Malto was just an example by the way, it could be poptarts or whatever else is higher GI than you’d like…
