Oreos are getting a skinny new look, and its maker says the new cookie is a "sophisticated" snack for grown-ups that isn't meant to be twisted or dunked. Mondelez International says it will add "Oreo Thins" to its permanent lineup in the U.S. starting next week. The cookies look like regular Oreos and have a similar cookie-to-filling ratio, except that they're slimmer. That means four of the cookies contain 140 calories, compared with 160 calories for three regular Oreos.
