NEW YORK — PepsiCo says it's dropping aspartame from Diet Pepsi in response to customer worries and replacing it with sucralose, another artificial sweetener commonly known as Splenda.
The decision to swap sweeteners comes as Americans keep turning away from popular diet sodas. Rival Coca-Cola said this week that sales volume for Diet Coke, which also uses aspartame, fell 5 percent in North America in the first three months of the year.
Atlanta-based Coca-Cola said in a statement that it has no plans to change the sweetener in Diet Coke, which is the country's top-selling diet cola.
