Consumers vary in their attitudes and expectations about dietary fibre: analysis of answers to a pan-European online survey.
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
objectivesDietary fibre (DF) has known health benefits, but consumer intake remains below recommended levels. This survey aimed at gathering and structuring information about DF-related attitudes of European consumers, including motivations and barriers, as well as preferred incentives for increasing DF intake.
participantsRepresentative sample of 7247 subjects from seven countries.
settingOnline survey.
designParticipants completed a questionnaire focused on knowledge about DF, perceived intake and reactions to incentives. Hierarchical clustering analysis was used to define ‘clusters’ based on response profiles and ‘groups’ based on socio-demographic characteristics.
resultsConsumers had a relatively good overall understanding of DF. However, responses to more detailed questions revealed knowledge gaps. Half of respondents said they consumed enough DF. Among proposed incentives for increasing intake, respondents preferred the labelling of fibre-rich products, then the inclusion of fibre in a wide variety of foods. Five answer clusters were identified: ‘committed consumers’ (sufficient DF intake, convinced of benefits), ‘sceptical’ (little DF-related knowledge, unconvinced), ‘informed consumers’ (good DF knowledge, insufficient intake), ‘helpless consumers’ (low intake, unclear about how to increase) and ‘resistant consumers’ (little concern and knowledge, rejection of all incentives). Socio-demographic groups displayed slight differences in response profiles (e.g. relative to the whole sample: white-collar workers tended to be ‘committed’ rather than ‘resistant’ consumers, and seniors tended to be ‘informed’ or ‘helpless’ rather than ‘sceptical’).
conclusionsThis study helped define subpopulations of European consumers based on DF-related attitudes and behaviours. Socio-demographics somewhat explained these differences and should be considered when developing strategies for increasing DF consumption.
