Special Issue Information

Dear Colleagues,

Social media has become a significant influence on the population’s habits and lifestyle. One aspect that has been impacted is eating behaviors, shaping dietary choices, habits, and nutritional outcomes. As these platforms become increasingly embedded in daily life, their role in shaping perceptions of food and health warrants careful examination. While social media can promote healthy eating and foster supportive wellness communities, it also has the capacity to disseminate misinformation and contribute to the development of unhealthy eating patterns.

Digital content yields both beneficial and detrimental effects. On one hand, social media can facilitate healthier dietary choices and increase nutritional awareness. On the other hand, it may exacerbate disordered eating behaviors, such as orthorexia and binge eating, driven by the promotion of unrealistic body standards and the proliferation of diet trends.

Potential topics include, but are not limited to:

  • Social media influencers shaping eating behaviors.
  • Impact of food-related content on various demographic or diverse ethnic groups.
  • Social media as a tool for public health campaigns and education.
  • Social media, misinformation, and unhealthy eating habits.
  • Food photography and visual esthetics on appetite and food choices.
  • Social media use, self-esteem, and body image concerns in the younger population.
  • Algorithm-driven content in promoting or discouraging healthy eating behaviors.
  • Social media's impact on eating behaviors across different cultures.
  • Addictive behavior regarding social media and eating habits.

Background: Social media platforms increasingly influence dietary behaviours, with cooking videos emerging as a key tool for promoting healthy eating. However, limited research has examined how such digital content affects adults in established adulthood. Objective: This study investigates the relationships among cooking behaviour, engagement with healthy cooking videos on Instagram, and healthy eating behaviours among Taiwanese adults aged 30 to 45. Methods: A cross-sectional online survey collected valid responses from 488 participants (effective response rate = 81.3%) who regularly cook and engage with food-related content on Instagram. Structural equation modelling (SEM) was used to test hypothesised relationships. Results: Cooking behaviour was positively associated with engagement in healthy cooking multimedia (β = 0.262, p < 0.01). Engagement significantly predicted healthy eating behaviours (β = 0.399, p < 0.001) and mediated the effect of cooking behaviour on dietary outcomes (indirect effect = 0.105, 95% CI [0.044, 0.204]). Cooking behaviour alone was not directly associated with healthy eating behaviours (β = 0.009, n.s.). Conclusions: Engagement with healthy cooking videos enhances healthy eating practices among adults in established adulthood. These findings highlight Instagram’s potential as a digital health promotion tool and support the integration of culinary media into public nutrition strategies. Full article

Background: Social media platforms such as TikTok are significant sources of nutrition information for adolescents and young adults, who are vulnerable to unregulated, algorithm-driven content. This often spreads nutrition misinformation, impacting adolescent and young adult health and dietary behaviors. Objectives: While previous research has explored misinformation on other platforms, TikTok remains underexamined, so this study aimed at evaluating the landscape of nutrition-related content on TikTok. Methods: This study evaluated TikTok nutrition-related content by (1) identifying common nutrition topics and content creator types; (2) assessing the quality and accuracy of content using evidence-based frameworks, and (3) analyzing engagement metrics such as likes, comments, and shares. Results: The most common creators were health and wellness influencers (32%) and fitness creators (18%). Recipes (31%) and weight loss (34%) dominated the list of topics. When evaluating TikTok posts for quality, 82% of applicable posts lacked transparent advertising, 77% failed to disclose conflicts of interest, 63% promoted stereotypical attitudes, 55% did not provide evidence-based information, 75% lacked balanced and accurate content, and 90% failed to point out the risk and benefits of the advice presented. A total of 36% of posts were considered completely accurate, while 24% were mostly inaccurate, and 18% completely inaccurate. No statistical significance was associated between the level of accuracy or evidence and engagement metrics (p > 0.05). Conclusions: TikTok prioritizes engagement over accuracy, exposing adolescents to harmful nutrition misinformation. Stricter moderation and evidence-based nutrition content are essential to protect adolescent and young adult health. Future research should explore interventions to reduce the impact of misinformation on adolescent dietary behaviors and mental well-being. Full article
