In a recent study published in the journal NutrientsResearchers at the University of Sydney, Australia, evaluated the performance of diet -related positions on a well -known platform of social media, categorizing them based on engagement, quality and accuracy.
Their findings indicate that the platform prioritizes high levels of commitment or “sacred” about the accuracy of the content, leading to concerns about misinformation that can have a serious negative impact on adolescent nutrition and health behaviors. However, the study found that different levels of accuracy did not lead to statistically significant differences in commitment measurements.
Background
Social media is increasingly important as a source of nutrition and health information for younger ones. Its popularity among these demographic elements makes a critical tool for disseminating health information.
With over a billion active users each month, 63% of users on the platform evaluated in this survey is 10 to 29 years old and its algorithms prioritize short and inspirational video content rather than long -term or elaborate positions.
The nature of social media positions has increased concerns about misinformation that can spread quickly if an inaccurate position becomes viral, especially as a significant proportion of nutritional and health information not to be downloaded by experts such as nutritionists or nutritionists.
Bias, regulatory, inaccurate and other potentially harmful messages can increase body dissatisfaction and disturbed eating habits between young women and adolescents, who are more likely to rely on social media information. In addition, low -income populations may face greater exposure to misinformation due to obstacles to access to professional health care.
Previous research from other platforms shows that misleading content affects adolescent preferences, increasing the risk of developing obesity or adopting poor nutritional behaviors. Understanding the exposure of vulnerable age groups to content of weight loss or nutrition from sources of non -experts is the key to dealing with misinformation in social media.
For the study
In this study, the research team examined the commitment measurements, prevalence and characteristics of nutritional positions uploaded to the social media platform from September 2023 to March 2024.
The relevant positions were detected using the preferred reference data for systematic revisions and post-analyzes protocol for Scoping Reviews Protocol (PRISMA-SCR). A pilot study was used to identify hashtags and the positions had access through new accounts to reduce bias due to the algorithm. The sorting process set 1054 relevant positions, of which 250 were randomly selected for analysis.
The research team gathered information about the involvement by examining how many times a post was, commented, shared or stored, as well as the number of subscribers that the content creators had. Details of the nutritional relevance, language and accessibility of the suspension were also collected. The positions were grouped into nine groups based on their dietary focus and in eight groups based on the type of content creator (in one category, “Content Farms”, identified as large volumes of low quality content that exploit the algorithms).
The quality of the positions was evaluated on the basis of criteria such as the level of commitment (to evaluate the potential of misinformation), transparency (reliability and clarity of information), financial disclosure (sponsorships, nutritional projections or viewers’ update.
The positions were classified as “completely accurate” into “completely inaccurate” based on accuracy and graded advertising, where one showed the stronger alignment with evidence. The data set was then analyzed to create descriptive statistics and compare inaccurate and precise positions based on engagement.

Findings
Health and wellness influences represented 32%of positions, content -related content creators published 18%and creators of lifestyle content or other creators who do not focus on health or nutrition represented 18%. On the contrary, nutritionists, dietitians or other health experts were represented only in 5% of dietary seats and 4% for nutritionists, making content based on minority experts.
In terms of content, about 34% of the seats were about weight loss, meal ideas or recipes. In 32% of the videos, the influences shared “what I eat in one day” positions, which the study recognized as an important source of weight-convenience and misinformation. Nutrition supplements were discussed in 10% of the posts, while the diet to achieve specific goals was covered at 7%.
In almost half of the applicable positions, the creator used testimonies to promote his own business or product. Only 18% included transparent advertising and only 13% were identified and revealed sources of conflict of interest. About 63% of the posts were found to promote stereotypes and 55% did not provide information based on evidence. Only 10% of the posts emphasized the potential dangers associated with behaviors and products they promoted despite the possibility of damage.
The research team found that 36% of the posts were completely accurate, with 29% most accurate. On the contrary, 19% of the posts contained completely inaccurate information and 18% were mostly inaccurate. Only 12% of the positions received grade A, 12% A grade B, 20% A degree C and 15% A degree D. 41% could not be evaluated. Dietitians produced the most accurate positions, with 42% of their content being classified as absolutely accurate.
In particular, mainly accurate positions and grade A had the highest commitment on average, but the differences in commitment measurements between expensive and inaccurate positions were not statistically significant. This suggests that while reliability is important, the Tiktok algorithm does not necessarily favor accurate content in relation to misleading content.

Conclusions
The platforms of social media, including analyzes in this study, are mainly dominated by creators of non -expert content. While they are popular, these creators can share information that has no scientific credibility.
The findings underline an urgent need for stricter moderation of nutrition misinformation, especially for places that promote extreme diets, unacceptable weight loss requirements or products with non -announced sponsorships.
Positions by qualified professionals, especially those related to weight loss, should be more attention to minimizing damage to vulnerable groups such as young adults.
As for the videos “what do I eat in one day” they were highlighted as a key misinformation lever, enhancing the unrealistic dietary standards. This, along with the lack of platform regulation on misleading content, proposes the need for more preventive interventions.
The study requires policies that encourage platforms to verify the credentials of health creators and promote the diet based on evidence of viral but misleading content. An effort is also needed to educate users about the misinformation of the social media to minimize the impact of exposure to misleading content.
