I have been treating myself with sugar free Popsicles (Popsicle brand). I do not understand the nutrition information, however....

1 Pop, 55 grams
calories 15
fat 0
sodium 0
Total carbs 3
Sugars 0
protein 0

Ingredients:Water,Glycerine,MaltoDextrin*,Citric Acid,Natural and Artificial flavors,guar gum,locust bean gum,aspartame,acesulfame potassium,ascorbic acid,red 40,yellow 6,blue 1

*Adds a trivial amount of sugar

If the Maltodextrin "adds a trivial amount of sugar", and there are no sugar carbs listed, where are the 3 grams of carbs coming from? Is glycerine a carb, is it a sugar alcohol?

Any thoughts? Thank you.
