Influence of moral reasoning and environmental concern on sustainable food consumption behaviors: A gender comparison among university students

Currently, South American countries face social and environmental challenges that can be addressed through the transformation of food purchasing and preparation patterns. This study aims to enhance comprehension regarding personal factors influencing sustainable food consumption, by examining the impact of moral reasoning and environmental concern on this behavior. The responses of 233 Chilean university students to an online self-report survey were analyzed using Partial Least Squares Structural Equation Modeling. The results have shown that moral reasoning and environmental concern positively impact sustainable food consumption behaviors, such as opting for food with minimal packaging, conserving energy during cooking, and repurposing food waste. Additionally, significant gender differences in these effects were observed. These novel findings provide further evidence supporting the necessity of bolstering moral education and environmental consciousness to foster the adoption of sustainable food consumption practices among university students in developing South American nations. Furthermore, the results underscore the importance of considering gender distinctions in education, particularly in light of entrenched family and societal roles. • The findings confirm the significant role of both moral reasoning and environmental concern in influencing sustainable food consumption. • The PLS-SEM model emphasizes the substantial impact of moral reasoning on environmental concern. • The finding supports a gender-differentiated effect of moral reasoning on environmental concern. • The results support a gender-differentiated effect of environmental concern on sustainable food consumption.
