Level 5 - mechanism / opinion, no new human data
Narrative review discussing definitions and conceptual frameworks without systematic search criteria or new experimental human trial data.

What was done
This narrative review examines the definitions and physiological roles of dietary fibre and bioactive compounds. It outlines their interactions with the gut microbiota, discusses defining the dietary fibre complex as an interconnected carrier matrix for bioactive compounds, and reviews intake and bioaccessibility data for polyphenols in the contemporary Spanish diet.
What was found
The abstract reports no numerical findings, sample sizes, or effect estimates. It reports conceptually that dietary fibre and bioactive compounds exert combined health effects via gut microbiota modulation, and proposes using intake levels from populations adhering to healthy dietary patterns as reference benchmarks for bioactive compounds.
Why it matters
Clarifying the terminology and functional relationship between fibre and bioactive compounds helps researchers evaluate plant food matrices as whole functional units rather than isolated nutrients.
Limits
This is a non-systematic narrative review providing conceptual discussion. The abstract provides no quantitative data, search methodology, sample sizes, or specific findings for the referenced Spanish dietary data.
