Coming Soon: Calorie Count on Movie Popcorn Trains, planes, grocery stores must also post calories By Evann Gastaldo, Newser Staff Posted Aug 31, 2010 10:20 AM CDT 10 comments Comments This delicious bucket of popcorn is about to be ruined for you, thanks to the FDA's requirement that movie theaters post calorie counts. (©CLF) (Newser) – There are some things you just don’t want to know … and the number of calories in that buttery movie popcorn you’re about to enjoy is probably one of them. Chain restaurants are already required to post calorie counts under the new health care law, and the FDA wants to require the same of other places that serve food—from airplanes to, yes, movie theaters, the Wall Street Journal reports. An official decision on who must comply will come in December, and nutrition advocates are happy. Movie theater advocates, not so much. "People don't go to movie theaters for the primary purpose of eating," says one. "Why aren't ballparks covered? You think the food served at ballparks is healthy?" (The answer: Stadiums aren’t considered chains ... and no, that food is not healthy.) Click here for a little preview of just how unappetizing that movie popcorn is about to become.
