Introduction: Dietary fibre (DF) is recognized as healthy for long, so that health claims are
allowed by the European Food Safety Authority (EFSA) due to its proved benefits, extended but
not only confined to many diseases of the gastrointestinal tract.
Objective: This work intended to analyse the level of information about DF in 10 countries,
situated in Europe, Africa and South America.
Methods: A descriptive cross-sectional study was undertaken through a survey based on a
questionnaire of self-response applied to a sample of 6010 participants. The data were lately
treated by factor and cluster analyses, including validation methodologies.
Results: Factor analysis showed that ten of the twelve items used to assess the knowledge about
DF could be arranged into two factors: one related to health effects (α =0.854) and the other to
the sources (α =0.644). Furthermore, cluster analysis showed that the participants could be
divided into three groups: 1) Good knowledge about sources and health effects of DF; 2) Good
knowledge about the sources of DF but poor knowledge about the health effects; 3) Poor
knowledge about the sources and health effects of DF. Conclusions: The results clearly allowed identifying two factors and three clusters, and the
variables that most influenced cluster membership were country, living environment and level
