I read about this yesterday. Just the thought makes me want to scream. While I don't drink much milk (and the milk that I do drink comes from a local dairy where I can drive by and wave at the cows), this would also apply to other dairy products like sour cream, half & half, yogurt, etc. These are not benign additives and should be clearly labeled on the packaging.
I try to avoid artificial sweeteners like the plague...this would not help my cause!
