Online and Mobile Application Diet Information for Food Chemical Intolerances: An Evaluation of the Content, Quality and Health Literacy Demand.
Article in Journal of human nutrition and dietetics : the official journal of the British Dietetic Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
aimsTo quantify the content, understandability, actionability, readability, and overall quality of food chemical intolerance dietary information for patients available online and via mobile applications.
methodsContent analysis was undertaken between August 2023 and August 2024 of eligible webpages and mobile applications. Online material was evaluated for quality using the DISCERN tool, clarity using the Centre for Disease Control and Prevention's Clear Communication Index and health literacy demand using the Patient Education Material Assessment Tool and the Hemingway readability calculator. Mobile applications were evaluated for quality using the Mobile App Rating Scale.
resultsA total of 169 websites and four mobile applications were eligible for analysis. Almost all (95%) resources recommended an elimination diet for the management of food chemical intolerance, but only 56% advised food reintroduction. Overall, diet information regarding food chemical intolerance found online and in mobile applications was mostly of poor quality. Information found online was also of low clarity and written with a high health literacy demand. Of the information scored as being of good quality, these were written by health/medical organisations and dietitians.
conclusionFuture revision and development of online and mobile applications should aim to improve the quality and reduce the health literacy demand of food chemical intolerance diet information. Additionally, online information and applications should include food reintroduction instructions, as prolonged dietary restrictions, especially without supervision, may increase the risk of nutrient deficiencies and disordered eating behaviours, and impact quality of life.
