A definition for dietary fibre.
The objective of this paper is to present a definition for dietary fibre based on recent advances that have taken place not only in human nutrition but also in plant cell-wall science and animal nutrition. We propose a physiologically based framework definition but, recognizing the diversity of dietary fibre, we have proposed further classifications within this framework. We also suggest that dietary fibre be removed from the carbohydrate group of nutrients because some compounds defined as dietary fibre are not chemically carbohydrates. The definition and classification system clearly highlight areas where further studies are needed.
