Fibre has been shown to exert a number of benefits on gastrointestinal (GI) health, yet its intake is low. Addition novel fibres food products may increase fibre and improve gut health. The objective the present study was evaluate influence three GI outcomes in healthy human subjects. A total twenty participants (ten men ten women) with normal BMI (23 ( sem 2) kg/m 2 ) participated randomised, double-blind, cross-over five treatment periods. Participants consumed maltodextrin control or 20–25 g/d from soluble maize (SCF) resistant starch (RS), alone combination pullulan (SCF+P RS+P). periods were 7 d 3-week washout between Stool samples collected day each period, tolerance assessed via questionnaire days 1 6. There no differences stool weight consistency. SCF significantly reduced pH increased SCFA production compared RS control. RS+P percentage butyrate all other treatments. Overall, symptoms minimal. SCF+P led highest score 1, while had Both treatments caused significant shift microbial community.
