Menu to Meal (M2M) Menu Labeling Intervention Study

This study evaluates the impact of culturally tailored menu labeling interventions on psychosocial factors and ordering behavior among customers in two independently owned Hispanic restaurants in East-Central Texas. Participants will be exposed to one of three sequential menu conditions at each restaurant: (1) a standard menu without nutrition information, (2) a paper menu with bilingual nutrition labels, or (3) a digital menu app enhanced with Augmented Reality (AR) and Artificial Intelligence (AI) providing interactive nutrition guidance. The study will assess whether menu formats influence nutrition literacy, decision-making confidence, self-efficacy, attitudes, behavioral intentions, and actual ordering behavior. Data will be collected through surveys, purchase receipts, and app interaction logs.

Inclusion Criteria: * Adults aged 18 years or older * Patrons dining at participating Hispanic restaurants during designated study hours * Able to read and speak English or Spanish * Willing and able to provide informed consent * Pregnant women are eligible to participate, as the study procedures pose minimal risk Exclusion Criteria: * Minors under 18 years of age * Individuals with visual or cognitive impairments that prevent interaction with the menu formats or AR/AI technology * Individuals who have participated in a prior phase of the study * Restaurant staff involved in study implementation
