When 9-year-old Maya Lopez brings her lunch to school in Bloomington, Illinois, her mother Jessica scans every ingredient label, wary of what might hide in plain sight. She’s not alone. Across the United States, a quiet urgency is building among parents, caregivers, and health advocates demanding clearer rules around ultra-processed foods (UPFs)—and a new study shows overwhelming public support for action. Researchers Brenna Ellison of Purdue University and Maria Kalaitzandonakes at the University of Illinois Urbana-Champaign surveyed 990 Americans to gauge support for six potential UPF policies, revealing not just concern, but a hunger for guidance. With federal definitions still absent despite growing public attention, the findings offer a roadmap for policymakers navigating one of the most pressing public health conversations of our time.
The study, published in PLOS One, underscores a national appetite for transparency. Nearly 80% of respondents supported information-based policies—such as a federal definition of ultra-processed foods and dietary recommendations—highlighting a public eager for clarity in a landscape clouded by marketing and misinformation. "They really want that basic information, including definitions and intake recommendations," Ellison said. "Without knowing what is or is not a UPF, it's difficult to know how else they may want these products regulated." This foundational knowledge gap is especially critical for families trying to make informed choices, particularly when 60% of calories in the average American diet come from ultra-processed sources.
Support extends well beyond information. A striking 73% of respondents backed restrictions on ultra-processed foods in schools, the highest among all restriction-based policies. This cross-partisan consensus—shared equally by Democrats, Republicans, and Independents—reflects deep concern for children’s long-term health. Restrictions in grocery stores and food assistance programs like SNAP also saw majority support, though taxation of UPFs did not, with only 44% in favor, a number Ellison attributes to rising food costs and the perennial unpopularity of new taxes.
What’s more, attitudes about UPFs themselves shape policy preferences. Respondents who viewed ultra-processed foods as unsafe or addictive were significantly more likely to support restrictions, while those who found them tasty were less inclined to back limits—especially in grocery stores. Republicans showed stronger support for restricting UPFs in food assistance programs, while Democrats leaned toward broader information campaigns. Yet in schools, political lines blurred—a rare point of unity in today’s polarized climate.
As federal agencies continue working toward formal UPF guidelines, this study offers more than data—it offers direction. With children’s health at the center, and public support firmly behind action, the path forward is becoming clearer. "If you are a decision-maker at the federal or state level, getting buy-in from your constituents is going to be important," Kalaitzandonakes noted. The ingredients for change are there. Now, it’s time to act.
