Artificial sweeteners have gone from diet darlings — touted for allowing people to get a hit of sweetness without the calories of sugar — to a more maligned ingredient, as evidence mounts suggesting a complicated net effect on calorie consumption.

The Food and Drug Administration rolled out its long-anticipated new food labels Friday, and they'll include new details on how much sugar is in food and reflect the sad fact that Americans eat more than they used to.
