The glycemic index is such a big nutritional deal for people with diabetes that it has sprouted spin-offs. One of the most well known of these is the glycemic load. But many people might find the “substance glycemic index” to be even more useful. People are still arguing about how usefu...

    Isn't this coming round to the old, simple system of 'exchanges'? I know this looks more accurate, but exchages were very easy to use. David's Response Derek Paice, who developed the substance glycemic index, sent me this reply to Martin’s comment: Unfortunately, the exchange method does not directly address A1C control. The glycemic index teaches that for those with type 2 diabetes, the carb source affects its impact on blood glucose. The exchange system, as I understand it, does not make that distinction. One exchange is about 15 grams of carbs, whatever the source. The SGI (substance glycemic index) defines glycemic effects based on food weight, not carbs. Further, for those with some mathematical capability the SGI can be personalized to predict their A1C. For people making negligible insulin, such as those with type 1 diabetes, a simple simulation model shows that total insulin dose is independent of glycemic index. Here’s where the carb is a carb is a carb rule applies. However, the AUC (area under the curve) is predicted to be lower for lower GI foods, a result supported by observations of some who have had type 1 diabetes for many years.

    The great thing about Mona Vie that has a low glycemic index and people are actually reducing their insulin after taking this!

    I think the GL is very helpful.  It seems to make sense to me. I've found some diet guidelines and great recipes at http://www.lowglycemicrecipes.net. They list carb amount, calories, fat, fiber content, Glycemic Index (GI), Glyco Load (GL). I haven't seen any other sites that offer the GI and GL together in their recipes. Other recipe sources don't have this information---and these recipes look and taste really delicious.  Does anyone else use this information?
