Background: Diet is the leading global cause of chronic illness, yet healthcare providers remain reluctant to recommend dietary approaches for prevention and treatment. In addition, food systems contribute roughly one-third of all human-generated greenhouse gas emissions (GHGs), along with deforestation, ocean habitat loss, zoonotic diseases, and environmental injustice. Modifiable diet choices, such as reducing animal-sourced foods (ASFs), are increasingly recommended by nutrition and climate scientists. However, promotion of plant-based foods (PBFs) and diets (PBDs) faces even greater resistance. Shifting toward plant-based diets requires identifying barriers and facilitators of food and diet acceptance, adoption, and adherence, and assessing the feasibility and effectiveness of sustained practice. Acceptance of PBFs and novel alternatives may promote PBD adoption, but long-term adherence must be specifically measured to determine drivers of sustained change.Objective: To advance understanding of how acceptance, adoption, and adherence relate to strategies for reducing ASF intake to support healthy and sustainable dietary change.Specific Aim 1: To investigate consumer acceptance of cultivated meat (CM) in a real-world setting examining attitudes, sensory experiences, and sociopolitical meaning-making at the first public CM tasting event in the world, using ethnographic and grounded theory methods.Specific Aim 2: To develop and test a novel intervention designed to increase health with increasingly plant-forward diet behaviors and exercise, testing for adherence to goals, stage of change and change readiness, and weight change in a six-month pilot randomized control trial.Specific Aim 3: To develop and test an adherence metric for popular diets that restrict ASFs among self-identified adopters, and associations with BMI, diet quality (HEI-2015), and diet duration.Methods: Three studies explored acceptance, adoption, and adherence among American adults voluntarily pursuing diet change, independently, through novel food trial or coaching.Study 1: An ethnography of the June 2024 UPSIDE Foods "Freedom of Food" pop-up in Miami-the world's first public CM tasting-included semi-structured interviews (n=19), media interviews (n=17), field notes, and secondary media/social media analysis. Grounded Theory was used to analyze sensory feedback, attitudes about food technology, willingness to consume (WTC), and ethical and political alignment, with attention to pre-existing belief systems and veg*n identity.Study 2: A pilot RCT enrolled older adults (n=20) at risk for diet-related NCDs in an intervention (1:1 with control) designed to provide education and support plant-forward change diet and other healthy lifestyle behaviors and to maintain those changes. Adherence and weight change in the intervention and control groups were measured at three timepoints over six months. Adherence to program goals, change readiness (Stage of Change), compatibility, engagement, and enjoyment of the program was evaluated in intervention groups (n=3) which were also assessed for fidelity. Study 3: An online survey (n=1282) recruited American adults who self-identify as following a vegan, vegetarian, Paleo, or whole-food plant-based (WFPB) diet. Weight, height, lifestyle and demographic factors were gathered for participant characteristics. Diet was assessed using the Diet History Questionnaire II (DHQ-II) and used to calculate diet quality using HEI-2015 score.Contributions: The results generated from this study can be used to design future interventions and nutrition education programs to increase acceptance and adoption and more accurately gauge adherence to alternative foods and diets. Individuals, clinical and public health professionals can support maintained adoption and increased adherence aligned with individual preferences and health goals in order to achieve health benefits while incrementally improving sustainability and health through frequent plant-based choices.
