Money: The War Of The Low-Carb Colas

The low-carb craze hits the soda aisles this month with the arrival of Pepsi Edge and Coca-Cola C2. Both drinks boast about half the carbs, sugar and calories of regular colas while promising a fuller flavor than diet sodas. The balancing act is achieved with a mixture of corn syrup and artificial sweeteners. But how do they stack up to the originals? Both low-carb versions taste surprisingly close to their full-sugar progenitors, but in a head-to-head tasting, C2 seems a little less artificial and has less of an aftertaste than Edge.
