Eating behaviors in the digital age: the role of social media and healthy diet literacy

Abstract Purpose The growing use of social media has increased access to online health and nutrition information, which may influence individuals’ eating behaviors. This study examined the relationship between digital healthy diet literacy, social media addiction, and eating behaviors among adults. Methods This cross-sectional study included 554 adults aged 18–64 years in Kırklareli, Türkiye. Data were collected through face-to-face interviews using a Personal Information Form, the Social Media Addiction Scale (SESMEB), the Bergen Social Media Addiction Scale (BSMAS), and the Digital Healthy Diet Literacy Scale (DHDL). Anthropometric measurements were obtained by the researchers. Results The participants’ mean age was 31.5 ± 10.4 years; 52% were female and 43.5% university graduates. SESMEB and BSMAS scores were higher among younger, single, and more educated individuals but lower among obese participants ( p < 0.05). DHDL scores were higher in those with higher education, regular exercise, and sufficient income, but lower in obese participants ( p < 0.05). Significant relationships were found between all scales and social media use characteristics (number of accounts, duration, importance of likes, participation in nutrition groups, and exposure to advertisements). Strong positive correlations were observed among SESMEB, BSMAS, and DHDL scores. Conclusions Social media addiction and digital healthy diet literacy are inter-related and may influence eating behaviors. Enhancing digital health and nutrition literacy may help reduce negative effects of social media and promote healthier eating habits. Level of evidence : Level III, cross-sectional analytic study.
