This study aimed to assess adults' perceptions and practices regarding sustainable diets and to identify sociodemographic factors influencing these outcomes. A cross-sectional online survey was conducted with 337 adults from February 5 to 21, 2025. Participants' awareness, willingness to engage in education, and practices related to environmental, health, and consideration aspects of sustainable diets were measured using a 5-point scale. The findings revealed low awareness of sustainable diets (1.80) and moderate willingness to participate in educational initiatives (3.18). Practice scores were highest in the health area (3.53), followed by environmental (3.06) and consideration (2.34) aspects. Females demonstrated significantly greater awareness of sustainable diets (2.06 vs. 1.64, p<0.001) and higher practice scores in the environmental (p<0.01), health (p<0.05), and consideration areas (p<0.001). Adults aged 50 to 59 exhibited the highest practice levels across all areas, including environmental (3.52) and health (3.83). One-person households reported lower practice scores compared to larger households in all areas (all p<0.01). Regression analyses indicated that female gender, older age, and larger household size were positively associated with sustainable dietary practices. In conclusion, while adults exhibited low awareness of sustainable diets, there was moderate interest in education. Sustainable diet practices varied significantly based on gender, age, and household size.
