Fishburg,

Once I recovered from the shock of reading that your friend has a doctor who actually recommended that she go low carb, I couldn't figure out why he or she would say that about cheese.

So I checked a variety of cheeses for carb count, and this is what I found, per cup of cheese:

Muenster - 1
Havarti - 0
Mozzarella - 4
Swiss - 4
Parmesan - 3
Provolone - 3
Jarlsberg - 0
Gouda - 6
Edam - 2
Brie - 11
Camembert - 11

Cheddar - 6
Colby - 3

Havarti was my new favorite omelet cheese because it has zero carbs, and I put at least 3/4 cup of cheese in my omelets. And Muenster, with only one carb gram per cup is another favorite. But I hadn't checked out the stats on Jarlsberg.

Cheddar cheese does appear to be the highest, except for Brie and Camembert. (That's a shock, but of course how often do you eat an entire cup of Brie or Camembert?) But Colby, the only other yellow cheese I could think of, has only 3. And Edam, which is white, has as many carbs as cheddar.

So maybe the doctor was right about cheddar cheese causing problems, at least in large quantities. Very interesting.
