Summary

This narrative review by Joanne Slavin, published in Nutrients in 2013, examines the evolving and sometimes inconsistent definitions of dietary fibre and prebiotics across regulatory, scientific, and clinical contexts. The paper likely distinguishes between structural and functional classifications of fibre, and considers which carbohydrates qualify as prebiotics based on their selective fermentation by beneficial gut bacteria. It provides a conceptual framework intended to support researchers, clinicians, and food regulators in applying consistent terminology.

UK applicability

The definitional and conceptual content of this review is broadly applicable to UK nutrition policy and dietary guidance, including frameworks set by the British Dietetic Association and Public Health England (now UKHSA), particularly in relation to recommended daily fibre intakes and functional food labelling.

Key measures

Definitional criteria for dietary fibre and prebiotics; classification of fibre types; fermentability characteristics; effects on gut microbiota composition

Outcomes reported

The paper reviews and clarifies the definitions of dietary fibre and prebiotics, examining how these definitions have evolved and their implications for understanding gastrointestinal health and gut microbiota function.
