diet coke and coke zero.
same thing goes for diet pepsi and pepsi one.

what the hell is the difference? i cut out regular coke and pepsi a long time ago. been drinking diet for years. but im hooked on coke zero and cherry flavored coke zero. are they still as 'healthy' as the traditional diet colas?

Found this:

Coca Cola Zero - Sweetened with aspartame and acesulfame potassium., the reason this is different than Diet Coke is Coca Cola Zero is a sugar free version of the Classic Coke formulation. In other words, this is meant to be a sugar free version of the red cans of Coke you know and may or may not love. It has a redder, deeper color close to the color of Classic Coke and tastes far less like a diet soda (by many accounts) than Diet Coke.
