Reuters reports, “U.S. restaurants are starting to list calorie counts on menu items, but new research shows those labels may not be accurate enough, particularly when it comes to individual items. ‘The big story may be that there is such a huge spread in the numbers,’ said Lorien Urban, a nutrition researcher at Tufts University in Boston, who worked on the study of dozens of restaurants in three states. ‘Essentially what that is saying is, you really don’t know what you are getting.'”

“All told, only seven percent of the French fries, burgers and other food items the team sampled were within 10 calories from the stated values.That could be a hurdle for the new U.S. healthcare law, which requires restaurants with 20 or more locations to list calories on their menus in the hopes this will help curb the nation’s obesity epidemic.”
