The Food and Drug Administration announced today that it will crack down on food labels it finds "misleading," including the so-called "Smart Choice" labels we reported on last month. Critics say such labels often point consumers to unhealthy choices, instead of the healthy ones. For example, products that are 50 percent sugar have earned the "Smart Choice" labels on their packaging. So tonight, we ask: How confident are you that you know what you're eating? Tell us what you think. You can follow "Nightline" anytime on Twitter: http://twitter.com/Nightline.
