Diets were matched for all nutrients except daily FODMAPs, indicated in bold (paired t test).
*Total dietary fibre comprises fibre and resistant starch.
†The low FODMAP diet was supplemented with a daily average of 3 g psyllium.
‡The low FODMAP diet was supplemented with a daily average of 5 g Hi-Maize 220 (National Starch and Chemical Company; Bridgewater, New Jersey, USA).
§While there is a significant difference in lactose, 5 g lactose per sitting is considered well absorbed and tolerated in majority of people18.
FODMAP, Fermentable Oligosaccharides, Disaccharides, Monosaccharides And Polyols; NS, not significant.
