Oh yes. I'm such a nongeek I don't even know if something like my previous comment should be a topic under Forums. (I'm one of two people in the world who aren't on Facebook.)

Hi Everyone.

I'm definitely NOT a geek, but a type 2 who still uses pencils (remember those?) and paper (that white stuff that comes in pads) to log BGs, but I had an idea for data gathering, and Manny suggested that this group might be able to help.

An engineer friend, Derek Paice, came up with the idea of the "substance glycemic index," or SGI, which is essentially a GI but for all foods, not just carbs. He describes it in a free online booklet at Unfortunately, he's closed his website, which had some other information.

But my idea was that there's tremendous power in the online community, and if there were a way for people to measure their own SGIs and then post them to TuDiabetes, eventually there might be enough data to help people who didn't want to measure their own.

The idea is that you eat a food or a meal and then measure the area under the curve until it returns to baseline and compare that AUC with your AUC for a control substance, expressing it as a percentage. Derek used whole-wheat bread, but I think that's not a good control because the ingredients of whole-wheat bread can vary so much. Glucose would be better.

He used 60 grams of food, but one could use any amount.

The idea is that the GI used 50 g of "available carbohydrate," not a certain weight of food, and some foods might have carbs with a high GI but not much carb. The glycemic load is supposed to correct for that, but you can't get GLs for foods for which no one has calculated GI, for example, meat and nonstarchy vegetables. I'm type 2, but meat can make my BG go up.

Clearly, this wouldn't work for anyone using bolus insulin, but knowing the SGIs that had been calculated by type 2s could help some type 1s with food choices.

Anyway, right now it's just a vague idea. I was wondering if anyone else thought it had merit.

@Ginat: I just signed up for the SCiO with an expected delivery date in December 2014. With the developers opening it up for others to create their own apps, I am excited to see what might come out of it. I used the food thing to justify the buy-in.

@Ginat: I assume the Medtronic Pump is connected via USB. Have you connected your USB devices with Parallels so that the virtualized Windows can see them? Here is the documentation:

Comment by Ginat on May 29, 2014 at 12:02pm

Is anyone familiar with /heard of ScIO? It's a molecular imaging device that is supposed to give exact carbohydrate readings (among other things) in real time, not per unit, but for the real food you have on your real plate. Too good to be true? The device is still in the production stage.

Comment by Ginat on May 29, 2014 at 11:55am

Is there a way to download CareLInk to a Mac version 10.9.3? I have tried to run it through Parallels, but the computer does not "see" the CareLink to download the info. Super frustrating! Any help is appreciated! I've asked Medtronic customer service and Parallels customer service--so far no luck.

Network Engineer, Juniper MX series.

I just discovered that in Australia they have a fantastic system where food is labelled according to its glycemic index!
Check out this web link of the "Glycemic index foundation"
it would make life so much easier for us diabetics if they did this labeling in all countries.
How can we make this happen ?

Network Engineer anyone?
Been doing the Cisco and Microsoft thing for about 17 years. To this day, I am the only Type 1, female, tattooed geek that I know. Any others? :)
