Packaged foods offer convenience for families and individuals, but they can be a major source of saturated fat, sodium and added sugars, which when consumed in excess contribute to chronic disease. To help people build healthier diets, the U.S. Food and Drug Administration proposed a new front-of-package nutrition label in January 2025 that would inform consumers about the presence of these nutrients.

While the FDA works to finalize the label, a research team led by the University of California, Davis, suggested a design that highlights products that are high in added sugar, sodium or saturated fat. They suggest in a new study an easy-to-understand label that make the healthfulness of foods more apparent.

Their was published March 24 in the journal, The Lancet Public Health. 

The FDA’s effort to provide shoppers with an at-a-glance guide is an important step, said , UC Davis associate professor of nutrition and human development and corresponding author of the study.

The would require a small “nutrition info” box on the front of most packaged food. Saturated fat, sodium and added sugars would each be listed with a rating of “low,” “medium” or “high.”  This would be based on the % Daily Value, as defined by the FDA, which for these nutrients are a daily limit, in one serving. The labels would also list the numeric % Daily Value. 

However, to make nutrient content easier to understand, researchers suggest that front-of-package labels should only flag products that are high in added sugar, sodium or saturated fat with labels that says “high in” a specific nutrient. 

For example, a candy product might have one simple “high in added sugars” label. A pot pie might have “high in sodium” and “high in saturated fat” labels, researchers said.

The FDA label for the same candy and pot pie would list all those nutrients and the low, medium or high levels with the exact % Daily Value of each.

Putting labels to the test

Researchers conducted an online randomized controlled trial with more than 13,000 adults across the United States to compare the FDA’s proposed black-and-white nutrition info box to alternative designs to assess the effects of the labels on consumer understanding and behavior.

Falbe said “high in” label designs outperformed the FDA’s proposed label in helping participants quickly identify healthier choices. Using multiple “high in” labels, such as “high in added sugar,” “high in sodium,” or “high in saturated fat” also surpassed the FDA’s label in helping participants choose healthier foods for themselves in virtual shopping settings.

Also, compared to “high in” labels, the FDA’s proposed “nutrition info” labels caused participants to misperceive items such as processed meat and candy as healthier. “That’s probably because the FDA label listed two ‘lows’ and one ‘high’ for these products,” said Falbe. “The two ‘low’s’ may have created a false health halo, another reason the FDA should go with a ‘high in’ label.”

“This label will be seen every day by millions of Americans for decades, so the FDA should pick the best label,” Falbe said.

The new proposed label would be on display on the front of packages in addition to the nutrition facts panel already seen on the back or side of most food and beverage products. 

“A lot of people overconsume added sugars, sodium and saturated fat, so to be able to quickly see that ‘high-in’ label makes it very easy to say, ‘maybe I should avoid that today,’” said Brittany Lemmon, a Ph.D. candidate in epidemiology and lead author of the study.
