Will Food Labels Help Us Choose Healthier Foods?

In December of 2016, chain restaurants and many food establishments in the US will be mandated by the Food and Drug Administration (FDA) to display calories associated with their menu items.  The purpose of this mandate is to inform consumers with the goal of decreasing their consumption of high caloric restaurant food items.  Recent research in the area suggests that food labeling might be effective in decreasing customers’ caloric consumption.  However, the projected consumption decreases will likely be due to changes in restaurant menu offerings, rather than changes in consumer food purchasing behavior.

One such study (Bleich, Wolfson, Jarlenski, & Block, 2015) compared the calories associated with food items for restaurant chains that voluntarily displayed caloric information with restaurants that did not list caloric information. The results of the study indicated that throughout 2012, 2013, and 2014, restaurant chains that voluntarily posted caloric information offered lower calorie foods than those that did not display caloric information.  Restaurants that posted caloric information introduced more new food items compared to the restaurants that did not post the information.  Further these new foods also yielded less calories than those introduced by restaurants that did not post caloric information.  Throughout the study, calories associated with food items decreased over time with the restaurants that did not label their foods.  However, the calories remained higher compared to the foods offered by the voluntary labeling restaurants.

Another study (Cantor, Torres, Abrams, & Elbel, 2015) evaluated the effects of food labeling on consumers’ food purchases.  During 2008, 2013, and 2014, the investigators collected data on consumer food purchases from fast-food restaurant chains mandated to display the caloric information of menu items and similar restaurant chains that did not display the calories associated with menu items.  Consumers were also surveyed regarding their awareness of the food labels and the food labels’ impact on their food purchases.  Consumers of the food labeling restaurants reported being more aware of the labels and reported using the information to purchase lower calorie foods.  However, the data indicated no caloric differences in consumer food purchases from fast-food chains with food labels compared to those without food labels.  The survey results also indicated no difference in how often consumers purchased fast-food items. Although consumers of the food labeling restaurants reported being more aware of the food labels, their awareness, as well as reports of adjusting their food purchases decreased over time.

The combined results of these studies suggest the FDA’s mandate for restaurants to display calories associated with menu items will most likely not produce the intended changes in consumer behavior.  However, mandatory food labeling might encourage restaurants to offer healthier, lower calorie food options.  I am guessing these results are not quite what policy makers were expecting, as the stated purpose of the mandate is to inform consumers and promote healthier food choices.

Why is food labeling unlikely to change consumer behavior?

The answer is related to reinforcement and individual food preferences.  The consumption of high caloric food tends to be immediately reinforced by food taste, among other factors.  Menu labeling, on its own, is an antecedent-based intervention.  It does nothing to address the powerful reinforcers associated with eating high caloric foods.  Without the incorporation of consequence-based strategies designed to compete with powerful naturally occurring reinforcers, food labeling is likely to be ineffective at changing consumer food selections.

How might mandating food labels change restaurant menu offerings?

The mandate might do so by altering motivating operations related to sales.  Restaurants currently offering high calorie food options may introduce healthier items in an effort to compete with restaurants already offering healthier options. In this scenario, the mandate would increase the value of having lower calorie food items on the menu.  The mandate might also be indicative of potential increased regulations in the future.  If so, restaurants might introduce healthier food options to avoid further regulations.  In this scenario, the mandate would create an aversive condition that restaurants would attempt to avoid.
