actually all cheeses have carbs (dairy) In my 1992 Atkins book, it lists:
This is per 1 oz
Cheddar - .6 grms of carbs
Swiss 1 grm
American .6
Cottage 7
Cream Cheese .5
Camembert 1
Feta 1
Muenster .3
Provolone .5
So yes all cheeses have carbs,,,,, I have read that if it is 1 or under.. they can put Zero on the package
Hope that this helps!
