Research Question In the United States, more than 50% of the average calorie intake comes from ultraprocessed foods (UPF). High levels of UPF consumption have been linked to negative health outcomes including obesity, type-2 diabetes, cardiovascular disease, and cancer. As a result, multiple countries have implemented stop sign disclosures on the front of food products to highlight excessive levels of nutrient content often associated with UPFs. Unfortunately, consumers often make inappropriate inferences based on front-of-package (FOP) processing claims (e.g., natural) that have been shown to affect healthfulness perceptions beyond nutrient content alone (Rybak et al. 2021). In the U.S., the Food Labeling Modernization Act of 2021 calls for a new labeling system and specific requirements for processing claims to aid consumers in making healthful food choices. Consequently, this research examines the use of Chilean-style processing stop sign package disclosures to present objective information to consumers. In three experiments, we examine the direct effects of stop sign disclosures on healthfulness, disease risk, and purchase intentions as well as the indirect effects through product processing level. Additionally, we examine the attenuating effects of these disclosures on the favorable, and potentially misleading, inferences drawn from unregulated and regulated FOP processing claims. Method and Data In Study 1, we addressed two types of stop sign package disclosures for UPFs, one that simply identifies the product as an ultra-processed product (UPFdisc) and one that presents three specific processing attributes related to UPFs (PAdisc). The study utilized a 2 (UPFdisc: present vs. absent) x 2 (PAdisc: present vs. absent) between-subjects design with 392 online participants. Multi-item scales drawn from prior research included disease risk, perceived healthfulness, and purchase intentions (Keller et al. 1997; Berry et al. 2017). Perceived product processing level was also assessed as a mediator. In Study 2, we included an additional factor, FOP all-natural claim (present vs. absent), to explore how each disclosure type moderates the effect of a favorable, unregulated processing claim and how this moderation extends to downstream outcomes. Lastly, in Study 3 we investigate the robustness of Study 2 results by testing the USDA regulated organic processing claim, a different food category, and the currently implemented negative nutrient attribute stop sign disclosure (NAdisc). The study utilized a 2 (UPFdisc: present vs. absent) x 2 (NAdisc: present vs. absent) x 2 (FOP organic claim: present vs. absent) between-subjects design. Summary of Findings In Study 1, we found similar direct and indirect effects for both processing disclosure types, suggesting that the simple, single stop sign disclosure may help consumers accurately determine the level of product processing and healthfulness, and lead to downstream effects on purchase intentions. In Study 2, in the absence of either disclosure type, the unregulated allnatural claim had favorable indirect effects on our outcome variables; however, in the presence of either the single UPFdisc or the three attribute PAdisc, the effects of the all-natural claim were no longer significant. These results further suggest the value of processing related stop sign disclosures to aid consumer perceptions and support the use of a simple, single disclosure. In our third study, we tested the UPFdisc and the USDA regulated organic FOP claim. We also examined the effects of the NAdisc which is currently used on UPF products in other countries (e.g, Chile). Consistent with our theorizing, in the absence of either disclosure the organic claim had favorable indirect effects on our outcome variables, and the presence of the nutrient disclosure did not attenuate these effects. Alternatively, the single UPFdisc again successfully attenuated these effects, consistent with Study 2. Key Contributions There is an extensive list of medical research within the past five years that has shown relationships between UPF consumption and severe disease risk, including type-2 diabetes, cardiovascular disease, hypertension, advanced heart age, cancer, and obesity (e.g., Mendoca et al. 2016; Juul et al. 2018; Piore 2021). The FDA (2022) is currently conducting research to select a FOP symbol that food companies could use on a food product to convey that a product is "healthy" but have yet to offer any objective definition of what is "healthy." In the past their definition has been linked only to nutrient information (e.g., saturated fat, sodium); however, it has become clear in this and other research (Caldwell 2021; Rybak et al. 2021) that consumers perceive product healthfulness to include attributes beyond just nutrient levels and that reduced processing is viewed favorably. In all three experiments, disclosures informing consumers that the product is ultra-processed significantly reduce healthfulness evaluations. These effects occur despite a nutrition facts panel and ingredients list presented on the back of the package, and the results extend beyond nutrient stop sign disclosures. Further, product processing level evaluations mediate effects on the downstream outcomes of healthfulness, disease risk, and purchase intentions. [ABSTRACT FROM AUTHOR]
