Menu Nutrition Labels Don’t Change Habits

Study: Even when calorie count is known, consumers don’t alter the way they eat

Letting consumers know exactly how many calories are in their food might do little to change their eating habits, a new study suggests.

The results show that, in the case of one fast-food chain in Washington, adding nutritional information to menus did not change consumer behavior after one year. has learned that the study comes just a few months before the nation is set to post mandated nutrition labels on menus at restaurants with 20 locations or more.

The findings suggested that nutrition labels alone might do little to ease the obesity epidemic, the researchers said. Additional public health campaigns might be needed to explain how the labels can be used by consumers to manage their diet and improve health.

“Obesity has lots of contributing causes, and so controlling it will undoubtedly require lots of contributing solutions,” said Elizabeth Pulos, a researcher at the Tacoma-Pierce County Health Department in Tacoma, Wash., who has studied nutritional labels on menus and was not involved in the new study. While the jury is still out on how effective labels are at helping people lose weight, as a consumer, Pulos would nevertheless like to know what’s in her food, she said.

The new findings also suggest that those who want to eat healthier already know which menu options contain fewer calories, so making nutrition information available doesn’t change these customers’ behavior, the researchers said.

Because the study looked at only one restaurant chain in one part of the country, more research needs to be done to determine if labeling might have a bigger impact if implemented on a larger scale.

The results were published on January 14 in the American Journal for Preventive Medicine.

Nutrition labels

So far, just a handful of studies have looked at the real-world impact of displaying nutrition labels on restaurant menus. One study found no change in consumer behavior. Another found that consumers, on average, purchased foods containing fewer calories after nutrition labels were added, but it was not clear if this effect was sustained for more than one month.

To build on this work, researchers from Duke-National University of Singapore (NUS) Graduate Medical School studied the effects of implementing restaurant menu nutrition labels on consumer purchases at restaurants in King County, Wash.They limited their analysis to one restaurant chain, a Mexican fast-food restaurant Taco Time.

The researchers compared the food-purchasing behavior at restaurants within Kings County, Washington to those outside of Kings County, which did not add nutritional labels.

After 13 months, they found no change in the average number of calories per transaction at the restaurants in Kings County relative to the restaurants outside of Kings County.

Fast food vs. sit-down

It’s possible that labeling may have more of an effect in sit-down restaurants than in fast food restaurants, Pulos said.

“In fast-food restaurants, people often don’t take a careful look at the menu — they know what they will order when they walk in the door.  I think this is less common in full-service restaurants,” she said.

Requiring labels might also prompt some restaurants to change their dishes or portion sizes so the numbers don’t look so scary to consumers, Pulos said.

In one study Pulos conducted, “chefs were sometimes sticker-shocked by the calories in their own meals, and made some changes. They just had no idea,” she said. “If food offerings are healthier, we might eat better without having to exert a lot of will power.”

Future studies should investigate how nutritional information should be conveyed on menus so it is useful to consumers, Pulos said.

The taco restaurant had identified healthful foods with a “Healthy Highlights” logo before the labeling was required. Perhaps, this was all the information consumers needed to make a decision, the researchers said.

“A simple logo identifying which foods are healthiest may be all it takes to convey that information to those consumers who wish to choose a healthier alternative,” said study researcher Eric Finkelstein, an associate professor of health services at Duke-NUS. “The additional information appears not to have made a difference,” he said.
