FDA takes on trans fats

The FDA is turning up the heat on artificial trans fats, saying it no longer considers the heart-clogging additives to be generally safe in foods. It's a major policy shift and the first step in banning artificial trans fats from the nation's food supply. Without that "generally safe" designation, it will eventually be illegal to sell foods containing man-made trans fats. Anderson discussed all this with Senior Medical Correspondent Elizabeth Cohen.

Michael Moss is the author of "Salt Sugar Fat: How the Food Giants Hooked Us" and has plenty to say about trans fats.
