On May 7, all US chain restaurants with 20 or more locations—and that includes coffee shops, bakeries, and movie theaters that sell food—had to start posting the calorie content of their menu items.
The rationale behind the US Food and Drug Administration (FDA) mandate, set forth in the Affordable Care Act in 2010, was that it might make customers think twice about ordering a meal that contained more calories than they should consume in an entire day. But whether posting calorie counts will help trim the proportion of US adults and children who are overweight or obese remains to be seen.
