So I did a little experiment and tested my blood sugar before and after eating some of those pork rinds.

I tested before eating them, 30 mins after, and 1 hour after eating them. My blood sugar stayed the same in all three tests.

I'm not sure if this proves anything, but eating the maltodextrin did not seem to effect my blood sugars. I would think if my insulin spiked that my blood sugars would rise.
