Food marketing influences eating preferences and choices, especially among adolescents, contributing to the rise of overweight, obesity, and other chronic health disorders. Recent social media advancements have provided food marketers with platforms to reach out to many in more personal and authentic ways as compared to classical media advertising. Such personalized and borderless social media platforms allow marketers to easily use owned, paid, and earned (word-of –mouth) marketing strategies, including paid and non-paid influencers to reach younger target audiences. This study therefore aims to explore food messages adolescents (12–18 years old) encounter on social media, and assess these messages for their sources, the presence of core and non-core food, and the marketing strategies employed. To attain an in-depth understanding of the food messages that adolescents are continuously exposed to, we carried out a diary study with 21 Flemish adolescents who took screenshots of food images they encountered on their social media platforms for the duration of one week. A quantitative and qualitative content analysis of 611 images revealed that adolescents are mostly exposed to messages of non-core (67% of images) and branded (49% of images) food, often (49% of images) presented in association with a social context such as hanging around with friends, eating at restaurants and celebrating with food. Adolescents often encounter branded food images through peers and social media influencers, the majority of which are part of earned (49% of branded images) or paid (40% of branded images) media food marketing. This research provides an in-depth understanding of the social media messages that adolescents encounter on a daily basis and sheds light on food norms typically communicated on social media by marketers, peers, and influencers. Study findings highlight prominent social media food messages that should be tested for their persuasiveness, providing insights for future research that aims to assess the effects of social media food marketing on adolescents. Based on the study findings, we call for relevant policy actions that address current social media marketing strategies targeted at adolescents.

Packaging is increasingly recognized as an essential component of any marketing strategy. Visual and informational front-of-pack cues constitute salient elements of the environment that may influence what and how much someone eats. Considering their overwhelming presence on packaging of non-core foods, front-of-pack cues may contribute to the growing rates of overweight and obesity in children and adults. We conducted a systematic review to summarize the evidence concerning the impact of front-of-pack cues on choices and eating behaviors. Four electronic databases were searched for experimental studies (2009–present). This resulted in the inclusion of 57 studies (in 43 articles). We identified studies on children (3–12 years) and adults (≥ 18 years), but no studies on adolescents (12–18 years). The results suggest that children and adults are susceptible to packaging cues, with most evidence supporting the impact of visual cues. More specifically, children more often choose products with a licensed endorser and eat more from packages portraying the product with an exaggerated portion size. Adults’ eating behaviors are influenced by a range of other visual cues, mainly, package size and shape, and less so by informational cues such as labels.

Objective: To assess the relationship between exposure to social media food messages and self-reported adolescent eating outcomes (including food intake, perceived norms, and food literacy). Design: A cross-sectional survey was used to assess reported exposure to core and non-core food messages (including marketing messages) on social media, as well as reported food intake, perceived norms, food literacy, attitudes, self-regulation, among others. Setting: 18 secondary schools across Flanders, Belgium Participants: 1002 adolescents 11 to 19 years of age. Results: Self-reported exposure to food marketing and overall food messages on social media were positively associated with eating attitudes, behaviors, perceived norms and food literacy among adolescents. Interestingly, the relationship between food exposure and intake was shaped differently depending on food type; descriptive norms mediated the positive relationship between non-core food social media exposure and non-core food intake (e.g., indirect effect estimate on self-reported sweets consumption is 0.005, se 0.002, p<0.01), while food literacy mediated the positive relationship between core food social media exposure and core food intake (e.g., indirect effect estimate on self-reported vegetable consumption is 0.01, se 0.003, p<0.000). Conclusions: This study highlights the significance of social media in relation to adolescent eating. There is an opportunity for health professionals to use social media in the promotion of core food among adolescents. We call for relevant policy actions to regulate the marketing of non-core food to adolescents on social media.

Current food production and consumption patterns pose serious threats to our global environment. The goal of the current research is to investigate whether the presence of specific informational cues, i.e., ecological labels and nutrition labels, can improve the environmental impact of food choices. Two online experiments were carried out in which young adults were asked to select products in a grocery shop setting, and to indicate quantities (in grams) for a hypothetical one-person meal. In the first experiment (N = 142), we varied the theme (sustainability vs. nutrition vs. control) of the labels alongside the products. The labels displayed a summarized product score (i.e., the products’ actual nutri-score), but this was either presented as the nutritional score or as the ecological score of that product. In the second experiment (N = 250), we again varied this label theme as well as the level of complexity, namely interpretative (i.e., simple) vs. reductive (i.e., detailed). While the results of the first experiment revealed no impact of the labels, the results of the second experiment suggest that labels with a sustainability theme can influence young adults to compose a more sustainable meal with less meat, and with a lower carbon and blue water footprint. The labels’ level of complexity did not impact the different eating outcomes. In conclusion, while these results point to the potential use of labels with a sustainability theme, it is important to note that the results did not consistently replicate across studies and analyses and should therefore be interpreted with caution. A possible explanation for the effect of eco-themed labels might be that they trigger pro-environmental objectives during decision-making, and prime people to consider the sustainability of their food choices.
