In light of escalating environmental and public health challenges, the global food system plays a pivotal role in shaping sustainable futures. This study investigates how consumer food choices contribute to these outcomes by examining the influence of sustainability concerns in two culturally distinct contexts: South Africa and Greece. Using a comparative framework, the research analyses food preferences, the role of environmental and health considerations, and consumers’ willingness to shift toward more sustainable diets. The study employs an adapted version of the Sustainable Food Choice Questionnaire (SUS-FCQ), marking its first comprehensive application in both countries. A total of 303 valid responses were collected (204 from Greece, 99 from South Africa). Key motivational patterns and cross-cultural differences in food-related behaviours were identified through descriptive statistics, exploratory factor analysis, and regression analysis. Findings indicate that sensory appeal, health, and ethical concern are the primary drivers of food choices in both countries, with affordability remaining a critical consideration. Ethical concern emerged as more influential than in prior studies, suggesting growing consumer awareness of sustainability issues. In contrast, socio-cultural acceptability and preference for plant-based diets were among the least influential factors. Cross-cultural comparisons revealed general alignment in food priorities. Greek participants placed greater emphasis on ethical considerations and local sourcing, while South Africans scored higher on taste and cultural acceptability than Greeks. The study also highlights demographic trends, showing higher sustainability concern among women and older participants, whereas younger and lower-income individuals emphasised affordability. These findings support the need for culturally and demographically tailored strategies to promote sustainable consumption. This research contributes to the academic literature by extending the SUS-FCQ to underexplored regions. It provides valuable insights for policymakers, educators, and food system stakeholders seeking to encourage more sustainable dietary practices through culturally appropriate and inclusive interventions.
À la lumière de l’aggravation des enjeux environnementaux et de la santé publique, le système alimentaire mondial joue un rôle crucial à la formation d’un avenir durable. Cette étude traite comment les choix alimentaires des consommateurs contribuent à ces résultats en analysant l’influence des préoccupations liées à la durabilité dans deux contextes culturels distincts : l’Afrique du Sud et la Grèce. Dans un cadre comparatif, la recherche étudie les préférences alimentaires, le rôle des considérations environnementales et sanitaires, ainsi que l’envie des consommateurs à adopter des régimes plus durables. L’étude utilise une version adaptée du Sustainable Food Choice Questionnaire (SUS-FCQ), marquant sa première application complète dans les deux pays. Un total de 303 réponses valides a été recueilli (204 en Grèce, 99 en Afrique du Sud). Les principaux schémas motivationnels et les différences interculturelles dans les comportements alimentaires ont été identifiés à l'aide des statistiques descriptives, des analyses factorielles exploratoires et des analyses de régression. Les résultats montrent que l’attrait sensoriel, la santé et les préoccupations éthiques constituent les principaux facteurs influençant les choix alimentaires dans les deux pays, l’accessibilité économique restant également un critère important. La préoccupation éthique s’est révélée plus influente que dans les études antérieures, suggérant une sensibilisation croissante des consommateurs aux enjeux de durabilité. En revanche, l’acceptabilité socioculturelle et les préférences pour les régimes à base de plantes figuraient parmi les facteurs les moins influents. Les comparaisons interculturelles révèlent une concordance générale des priorités alimentaires. Les participants grecs accordent davantage d’importance aux considérations éthiques et à l’approvisionnement local, tandis que les Sud-Africains obtiennent des scores plus élevés pour le goût et l’acceptabilité culturelle. L’étude met également en évidence des tendances démographiques, avec une préoccupation plus marquée pour la durabilité chez les femmes et les participants plus âgés, tandis que les jeunes et les individus à faible revenu privilégient l’accessibilité économique. Ces résultats soulignent la nécessité de stratégies adaptées culturellement et démographiquement pour promouvoir une consommation durable. Cette recherche contribue à la littérature scientifique en étendant l’application du SUS-FCQ à des régions peu explorées et fournit des informations précieuses aux représentants politiques, aux enseignants et aux acteurs du système alimentaire souhaitant encourager des pratiques alimentaires plus durables à travers des interventions culturellement appropriées et inclusives.

Abstract
In light of escalating environmental and public health challenges, the global food system plays a pivotal role in shaping sustainable futures. This study investigates how consumer food choices contribute to these outcomes by examining the influence of sustainability concerns in two culturally distinct contexts: South Africa and Greece. Using a comparative framework, the research analyses food preferences, the role of environmental and health considerations, and consumers’ willingness to shift toward more sustainable diets. The study employs an adapted version of the Sustainable Food Choice Questionnaire (SUS-FCQ), marking its first comprehensive application in both countries. A total of 303 valid responses were collected (204 from Greece, 99 from South Africa). Key motivational patterns and cross-cultural differences in food-related behaviours were identified through descriptive statistics, exploratory factor analysis, and regression analysis. Findings indicate that sensory appeal, health, and ethical concern are the primary drivers of food choices in both countries, with affordability remaining a critical consideration. Ethical concern emerged as more influential than in prior studies, suggesting growing consumer awareness of sustainability issues. In contrast, socio-cultural acceptability and preference for plant-based diets were among the least influential factors. Cross-cultural comparisons revealed general alignment in food priorities. Greek participants placed greater emphasis on ethical considerations and local sourcing, while South Africans scored higher on taste and cultural acceptability than Greeks. The study also highlights demographic trends, showing higher sustainability concern among women and older participants, whereas younger and lower-income individuals emphasised affordability. These findings support the need for culturally and demographically tailored strategies to promote sustainable consumption. This research contributes to the academic literature by extending the SUS-FCQ to underexplored regions. It provides valuable insights for policymakers, educators, and food system stakeholders seeking to encourage more sustainable dietary practices through culturally appropriate and inclusive interventions.| File | Dimensione | Formato | |
