Soft-drink purists have just a few months to scoop up as much Pepsi as possible: Starting in August, a new formulation of the soda is hitting store shelves.
PepsiCo announced last week that it's replacing the aspartame in Diet Pepsi with sucralose, the sweetener marketed under the brand name Splenda.
The reason for the change? "Customer worries" that aspartame isn't safe.
“Aspartame is the number-one reason consumers are dropping diet soda,” Seth Kaufman, a vice president at Pepsi, said.
That might be consumers' reason, but it's not a scientific one. As Julia Belluz points out at Vox, the European Food Safety Authority recently conducted a risk assessment on aspartame and "ruled out a potential risk of aspartame causing damage to genes and inducing cancer." Aspartame is not proven to cause bladder cancer, or brain cancer, or behavior problems, or any other diet-soda old-wives tales.
