Evaluating online nutrition information: a scoping review of young adults' source preferences and criteria for credibility and trustworthiness.
Synthesis in Frontiers in digital health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: The use of the internet to search for different kinds of information has become part of everyday life also for nutrition information. Therefore, it is important that the information is evidence-based, credible, and trustworthy. Assessing this is complicated by the declining importance of traditional health information gatekeepers and the rapid flow of information. This scoping review examines factors that influence the trustworthiness and credibility of digital information sources on healthy diets from the perspective of young adults. Methods: We conducted a scoping review with a comprehensive search of 5 databases and grey literature up to 12/2024, following the PRISMA-ScR guidelines. Two reviewers performed a two-stage screening process. The coding of trust- and credibility-influencing factors is based on the Misinformation Receptivity Framework and the Online Credibility Framework. Results: 48 papers were included, identifying 82 factors concerning the formation of trust and credibility in nutrition information. The most frequently reported factors are clarity of the information ( Discussion: Our findings suggest that most studies focus primarily on the receiver's characteristics. The existing literature often neglects factors like the author's reputation, the usability of digital platforms, and the accessibility of information. In addition, other studies have found that ethnicity and nationality can strongly influence assessments of information trustworthiness and credibility. However, this is not systematically reported in the analyzed papers. This shows that further research is needed on trust- and credibility-inducing factors. Furthermore, the results underscore the need for research that incorporates diverse perspectives and cultural backgrounds to achieve a comprehensive understanding of this critical area.
