The relationship between sustainable dietary behaviors, sustainable food literacy, healthy life awareness, and social media addiction in adults: a cross-sectional study in Türkiye

Our findings highlight that higher sustainable food literacy and healthy life awareness significantly predict greater adherence to the Mediterranean diet and improved nutritional sustainability, regardless of sociodemographic characteristics. Social media addiction was positively associated with both literacy and awareness, though it did not directly predict dietary adherence or sustainability. These results suggest that while social media use may enhance exposure to nutrition-related information, its impact on actual dietary behaviors is less direct. Targeted interventions should therefore leverage the informational potential of digital platforms, while also fostering translation of awareness into healthier and more sustainable eating practices.
