Résumé:
Social media has become a pervasive influence on young adults’ dietary habits worldwide.
This study investigates how social media affects food choices among Algerian university
students, considering cultural and economic factors. Using a cross-sectional survey, 261
students reported on their social media use, trust in nutritional information, physical activity,
and eating behaviors.
Participants completed a structured questionnaire assessing daily social media engagement,
trust levels, and dietary habits. Data were analyzed using chi-square tests to identify
associations between demographic variables and food-related behaviors. Comparative
analysis was conducted with a 2023 Pakistani study exploring similar themes.
Results show that 93.8% of students use social media daily, predominantly Instagram, and
76.8% trust online nutritional information. Frequent experimentation with new foods was
reported by 53.3%, though 54.1% perceive social media as promoting unhealthy eating.
Physical activity and income correlated with healthier habits, while younger students and
females exhibited greater social media use and trust. Following food trends was linked to
increased consumption of unhealthy foods. Comparisons with the Pakistani study reveal
consistent patterns across different cultural contexts.
These findings underscore social media’s complex role in shaping dietary choices and
highlight the need for culturally tailored interventions to improve digital literacy and promote
healthier eating behaviors.
