There’s an association between putting nutrition data on “front of package” food product labels and improved nutritional content in those foods, according to a new study.

Researchers analyzed 16 years of data on tens of thousands of products and their competitors, evaluating nutritional data on 44 categories of food products from 1996 through 2011. Altogether, they looked at data on 21,096 products, representing 9,083 brands, covering everything from energy bars to soup.

“For consumers, we found that the presence of a Facts Up Front FOP label on a package generally meant that the product had a better nutritional profile…”

“We wanted to know whether food companies were responding to increased public interest in healthier food,” says coauthor Rishika Rishika, an associate professor of marketing in North Carolina State University’s Poole College of Management. “In other words, is the market driving change in the nutrition of food products? And the evidence suggest that this is exactly what’s happening.”

Specifically, the researchers evaluated whether there was any impact when products adopted the “Facts Up Front” style FOP nutrition labels. Facts Up Front is a voluntary nutrition labeling program adopted by the food industry. Manufacturers participating in the program list the calories, saturated fat, sugar, and sodium per serving size of their food products on relatively large FOP labels. The products still carry the mandated nutritional information panels on the back of the packages.

To determine whether the voluntary FOP program had influenced the nutritional content of food products, the researchers looked specifically at two things.

For food categories in which at least one product had adopted the FOP labeling, the researchers evaluated differences in the nutritional quality of all products in the category both before and after any products adopted the FOP labels. They also compared these differences with food categories in which no products adopted labeling and that served as control groups.

The researchers calculated a product’s nutritional content using the Nutrient Profiling model, which includes a host of nutrients, such as sugar, fat, sodium, protein, and fiber.

The results showed a clear association between FOP labeling and changes in the nutritional content of food products. The researchers discovered five factors that were associated with the presence of FOP labels having a greater impact on nutrition:

  • Premium brands improved nutritional quality more than non-premium brands in the same category.
  • Brands that had narrower product lines, meaning they produced fewer products than their peers, improved nutritional quality more.
  • Products in categories that are broadly unhealthy, such as snack foods, showed a more pronounced response.
  • Foods in “more competitive” categories, meaning those in which there were many competitors at different price points, showed a more pronounced response.
  • Products that had adopted FOP labeling showed more improved nutritional quality.

The researchers also found pronounced changes in the content of nutrients that were singled out by the “Facts Up Front” FOP program.

Across all of the food categories in which at least some products adopted the FOP labels, there was a 12.5% reduction in calories; 12.97% reduction in saturated fat; 12.62% reduction in sugar; and 3.74% reduction in sodium.

“We had hypothesized that when nutritional information is clearly marked on the front of the package, that consumers would be more likely to consider it when deciding what to buy,” Rishika says. “This would, in turn, cause competitive pressure on other brands in that category to innovate and improve the nutritional quality of their products.

“The fact that the effect of FOP labeling was most pronounced for the nutritional variables on the FOP labels supports our theory,” Rishika says. “And the fact that the effect was stronger for brands that adopted FOP labeling also supports the hypothesis.”

The researchers have a few takeaway messages.

“For consumers, we found that the presence of a Facts Up Front FOP label on a package generally meant that the product had a better nutritional profile than competing products that didn’t have an FOP label,” Rishika says.

More broadly, the findings suggest that voluntary, highly visible nutritional labeling can be an effective tool for encouraging change on an industry level.

“However, it remains unclear which aspect of the program is more important,” Rishika says. “Is the fact that the program is voluntary more important, since it helps consumers identify brands that are choosing to share nutritional information on the front of package? Or is the fact that the FOP labeling is prominent more important, simply because the information is more clearly noticeable? Those are questions for future research.”
