Last summer, PepsiCo announced it would remove the controversial chemical aspartame from its Diet Pepsi soft drink.
Now, one year later, it's bringing the ingredient back.
Starting in September, Diet Pepsi will come in two versions: one with aspartame, housed in light blue packaging with a label touting Diet Pepsi's "classic sweetener blend." The other will contain sucralose, an artificial sweetener better known as Splenda, and will be sold in Diet Pepsi's now-familiar silver packaging.
There isn't any solid scientific evidence that artificial sweeteners cause health problems like cancer, but aspartame hasn't been able to shed its bad reputation among nervous consumers. PepsiCo removed aspartame last year in hopes of boosting sales, but alas, many fans didn't like the taste of the new formulation and demanded it back.
