A utilização de redes sociais e a exposição a conteúdo baseado em imagens tem- -se associado a uma imagem corporal mais negativa e a escolhas alimentares menos saudáveis em jovens adultos vulneráveis à influência das redes sociais. Objetivos: Caracterizar os influencers portugueses que criam conteúdos na área da alimentação e os seus conteúdos. Métodos: Realizado estudo observacional analítico transversal com utilização de conteúdos públicos. Foram avaliados influencers portugueses, com mais de 100000 seguidores, com pelo menos 6 publicações no feed nos últimos 6 meses, sobre alimentação, nutrição e saúde. Os dados foram recolhidos durante um mês e foram analisados os 10 dias com maior número de conteúdos. Após a seleção da amostra, foram analisados 42 influencers e 788 conteúdos. Resultados: Os influencers eram 71,7% do género feminino, 11,9% possuíam licenciatura em dietética e nutrição e 57,1% utilizaram a imagem corporal no feed. Observou-se que o género feminino utilizou mais imagem corporal no feed do que o género masculino. Dos conteúdos avaliados, 92,9% são instastories, 49,4% apresentavam, pelo menos, uma publicidade e 30% das alegações dos conteúdos não tinham evidência científica robusta. Os nutricionistas avaliados foram os que utilizaram menos publicidade. Na avaliação das opções de refeição, as hortícolas, a fruta e os cereais pouco refinados aparecem com uma frequência inferior à recomendada e os grupos da carne, pescado, ovo e gorduras surgem com uma frequência quase quatro vezes superior. Discussão/Conclusão: Os indivíduos avaliados não possuem idoneidade para comunicar nutrição. O algoritmo do Instagram filtra os conteúdos apresentados permitindo às marcas amplificar as suas vendas e perturba os usuários mais sensíveis no que diz respeito à imagem corporal. Orientações mais objetivas relativamente à publicidade nas redes sociais, estratégias digitais para a promoção da alimentação saudável, a explicação do algoritmo e o combate à desinformação por organismos públicos são necessários para uma utilização das redes sociais positiva.
ABSTRACT - Introduction: The use of social networks and exposure to image-based content has been associated with a more negative body image and less healthy food choices in young adults who are vulnerable to the influence of social networks. Objectives: To characterize the Portuguese influencers who create content in the food sector and their content. Methods: A cross-sectional analytical observational study was carried out using public content. Portuguese influencers were evaluated, with more than 100,000 followers, with at least 6 publications in the feed in the last 6 months about food, nutrition, and health. Data were collected for a month and the 10 days with the highest number of contents were analyzed. After selecting the sample, 42 influencers and 788 content were analyzed. Results: The influencers were 71.7% female, 11.9% had a degree in dietetics and nutrition and 57.1% used their body image in their feed. It was observed that the female gender used more body image in the feed than the male gender. Of the contents evaluated, 92.9% are instastories, 49.4% had at least one advertisement, 30% of the content claims had no robust scientific evidence. The dietitians evaluated were the ones who used less advertising. In the evaluation of meal options, vegetables, fruit, and low-refined cereals appear less frequently than recommended and the meat, fish, egg, and fat groups appear almost four times more frequently. Discussion/Conclusion: The evaluated individuals are not qualified to communicate nutrition. Instagram's algorithm filters the content presented, allowing brands to amplify their sales and upset the most sensitive users when it comes to body image. More objective guidelines regarding advertising on social networks, digital strategies to promote healthy eating, explanation of the algorithm, and the fight against misinformation by public bodies are necessary for a more beneficial use of social networks.
