Fermentable oligo-, di- and monosaccharides, and polyols (FODMAP) were analysed.
FODMAP levels ranged from 1.2 to 2.0 g/100 g DM in flours of 5 wheat species.
Dough proofing times decisively determined FODMAP contents in wheat breads.
FODMAP levels in wheat breads were effectively diminished by up to 90%.
Wheat products for IBS patients may be obtained by specific processing methods.
