Now I am not trying to encourage anyone from obsessing and counting all of their herbs when seasoning your plate.
However I smoke meat almost weekly and sometimes do a very heavy coat on the outside of the meat which I eat for the entire week. I was surprised that McCormick would list 0 carbs and 0 sugar when on some of their prepared rubs sugar was the second ingredient listed! I wanted to be aware of the hidden carbs I was consuming and thought I would share what I find.
Once again this is just is not to discourage daily use, just information when cooking large amounts of food ahead of time or just for interesting information! Also spices are different per brand where possible I used the USDA STANDARD REFERENCE for all figures since several of the brands will list 0 carbs and sugar due to a serving size being .25tsp.
I will add as I look up more information as well and please fell free to contribute!
