Low-Carb Coke

This story on low-carb Coke (I guess Diet Coke doesn't count?) reminds me of one of the more patently absurd things I've seen in a long time. In the local Harris Teeter, like many grocery stores I'm sure, they have started placing little flags signalling "Low-Carb Food!" to entice Atkins and South Beach fanatics.

That's all well and good, and I can't fault the stores for trying to capitalize on the latest health fad. But what was the first thing I saw labelled as such?

Butter. Unsalted sticks of butter. A low-carb food. Makes a great snack.
