And this is why: the FDA officially recognized stevia (the basis of the sweetener) as safe on 12/17 ... probabally the day before I started seeing all of these commercials!
Where will we 1st see the sweetener? According to an article on QSRmagazine.com:
Pepsi will launch two new products featuring its stevia-derived PureVia. Zero-calorie SoBe Lifewater, in berry, apple, and pomegranate flavors, will hit shelves soon along with Trop50, a light orange juice product with 50 percent less sugar and calories, which will debut in March 2009.
Coke is also putting its natural sweetener to work already, using Truvia to create Sprite Green, a 50 calorie Sprite variety that is aimed at active young adults. In addition to Sprite Green, Coke is launching two new Odwalla juice flavors using the sweetener.
