Prevalence of sustainability claims on packaged food.
Article in Public health nutrition, 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
objectiveGlobal food systems have a key influence on both health and sustainability. Dietary shifts that promote health and sustainability are regarded as a critical synergistic pathway for advancing human and planetary health. In response, consumer interest in the sustainability of food systems has prompted the use of claims highlighting positive sustainability attributes displayed on-pack. This study assessed the prevalence and types of sustainability claims displayed on packaged food in Australia.
designClaims data on packaged food were collected at five supermarkets in Sydney in 2024. We determined the prevalence of sustainability claims overall, by claim category and format (text or logo).
settingAustralia.
participantsNone.
resultsOver a third of products displayed at least one sustainability claim, the most prevalent being 'natural' and 'vegan'. Text claims were far more prevalent than logos (84 %
conclusionsFrequent use of broad and unspecific sustainability claims raises challenges for substantiation, and there is a risk that consumers are being misled. Our findings support the need for stronger regulation, including criteria for terms used in claims, to improve consumer trust and comparability across products.
