Study looks at NYC fast-food menu calorie counts
Like any fitness program, it works only if you pay attention to it.
A new study on New York City's effort to encourage healthy eating by posting calorie counts on menus shows that it worked for about one in six customers — or those who paid heed to them. Those who ignored the numbers or didn't see them ordered whatever they wanted, regardless of how fattening it was.
City health officials who conducted the study said that's good news. On any given visit, customers who looked at the counts generally ordered about 100 fewer calories than those who didn't, according to the results of the study published Tuesday in the British medical journal BMJ.
In 2008, New York became the first municipality in the U.S. to require chain restaurants to post the counts, and other places including California and Seattle followed suit. Starting next year, a federal law will require all chains with 20 or more locations to print calorie counts on menus. British fast-food restaurants are set to introduce a similar but voluntary initiative.
The study was the first large-scale look at the initiative's success at several different chains. Lynn D. Silver, assistant commissioner of the city Department of Health and Mental Hygiene and one of the study's authors, said it showed modest gains in getting people to order lower-calorie meals. But she said the law also led restaurants to widen their offerings of healthier food, such as salads.
"Calorie labeling alone won't cure the obesity epidemic but it is one part of trying to address it," Silver said.
About a third of adults in the U.S. are obese, according to the federal Centers for Disease Control and Prevention.
The study looked at lunchtime purchases at 11 fast-food chains around New York in 2007, before the city law was passed, and then again in 2009. Researchers asked customers for their receipts and spoke to them about their orders. There was no significant change overall. But customers did order fewer calories, on average, at three major chains: McDonald's, Au Bon Pain and KFC. The study notes that those restaurants also introduced healthier choices around the same time the law was passed.
Meanwhile, the sandwich shop Subway showed a big increase in the average calorie count of a lunch order, which the authors linked to the popularity of its "$5 foot-long" deal, introduced nationally in 2008.
The study found that more than 20 percent of customers at Subway and Au Bon Pain paid attention to the calorie counts, an increase from the overall average of 15 percent. Women were more likely to use them when deciding what to order, as were people in wealthier neighborhoods. Young people were the least likely to use them.
The study noted that people are increasingly relying on food prepared away from home.
"There is a strong and growing consensus that consumers want to know what they are eating so that they can make informed choices," the authors wrote.
In a separate development on Tuesday, McDonald's announced changes to its iconic Happy Meal, making the portion of French fries smaller and adding fruit.
Marion Nestle, a professor at New York University's Department of Nutrition, Food Studies and Public Health and author of the blog "Food Politics," said the study confirms that once people pay attention to the calorie counts, they make dietary changes.
"The next step has to be to get more people to look at the info," she said.
In New York City's Midtown at lunchtime on Tuesday, Carlos Muñoz, a 29-year-old student at a technical school, munched on a chicken wrap, fries and a soda from McDonald's.
"I don't really pay any mind to it," he said of calorie counts. "I figure one bad thing a day I should be able to burn away."
But he supported their presence on menus.
"You should know what you're putting into your body," he said. "If I'm ever curious, I'd like to know I can get the information."
Inside Starbucks, Alexandra Casey, 23, of Worcester, Ma., said she looks at calorie counts when they're posted. But as a vegan and avid runner, she was more concerned with overall nutritional content rather than just calories. For example, nuts might be high in calories but they're still a better choice than cake.
Casey applauded New York for leading the way in posting the counts but said eateries should provide more comprehensive information about the food and beverages they offer.
"It's not just about a number," she said. "The question is, what's the content of those calories."
