-- intro: With the new Food and Drug Administration rules requiring food sellers to post calorie counts on menu items, consumers are in for a shock. Some of their favorite items may lead to a little more belt tightening than they realized.
And it's not just calories. Consumers also will be able to ask for other nutritional facts, and some sellers must make those available upon request.
“Menu labeling is a landmark public health policy that will help people to decide for themselves how much and what they want to eat when dining out,” said Margo G. Wootan, the director of nutrition policy for the watchdog group, Center for Science in the Public Interest. “It also will spur restaurants to think more about and improve their offerings.”
Restaurants, movie theaters, pizza parlors, amusement parks, vending machines and food trucks are all subject to the rules. Companies with 20 or more locations have a year to comply.

“Customers pick and choose exactly what goes in to their own individual order, which allows us to meet virtually any set of dietary restrictions or preferences,” said Chipotle spokesman, Chris Arnold. “While you can load up a burrito to have a lot of calories, that's not what most of our customers do.”media: 27167950
