America's Unhealthiest Drinks Exposed. I'm not a coffee drinker but used to go into Starbucks with Jane to support her habit. For a while I was getting their iced "juice" drinks (can't remember the name). Until I looked at the nutrition info one day, a medium-sized cup (full of ice mind you so it wasn't 100% drink!) had more calories and more fat than an entire milkshake from Baskin Robbins. I've never bought anything from Starbucks since.
