Dietary fibres in the regulation of appetite and food intake: importance of viscosity

Publikation: Bidrag til tidsskriftTidsskriftartikelForskningfagfællebedømt

Dietary fibres have many functions in the diet, one of which may be to promote control of energy intake and reduce the risk of developing obesity. This is linked to the unique physico-chemical properties of dietary fibres which aid early signalling of satiation and prolonged or enhanced sensation of satiety. Particularly the ability of some dietary fibres to increase viscosity of intestinal contents offers numerous opportunities to affect appetite regulation. This may be linked to increased chyme viscosity, as linseed dietary fibre has water holding capacity and intrinsic viscosity which is comparable to that of psyllium and guar gum. Few papers on the satiating effect of dietary fibres include information on the physico-chemical characteristics of the dietary fibres being tested, including molecular weight and viscosity. For viscosity to serve as a proxy for soluble dietary fibres it is essential to have an understanding of individual dietary fibre viscosity characteristics. The goal of this paper is to provide a brief overview on the role of dietary fibres in appetite regulation highlighting the importance of viscosity and also include new findings on the role of linseed dietary fibre on appetite regulation.
