Abstract

Rationale: Research has shown that the behavioural effects of inulin vary depending on dose, whether combined with food or not, and length of time that the inulin is consumed. Objectives: The aim of this study was to examine the acute effects of 13g of inulin on digestive symptoms, mood and cognitive performance. Methods: This study compared 13g of inulin and maltodextrin placebo over a single day using a cross-over design (N=51), with a measurement of mood and cognition occurring across the day. Results: Inulin increased the number of motions occurring and the number of stools passed. Inulin was associated with a more negative mood and impaired cognition, especially episodic memory. Conclusions: Inulin can influence behaviour through a variety of mechanisms. Effects seen in this study could not reflect changes in gut flora due to the short time period studied. Other possible mechanisms are discussed.
