Rye bread

Moderate FODMAP (Caution)Safe at 1 thin slice

Is rye bread low FODMAP?

Rye bread is moderate FODMAP, safe in limited portions (Safe at 1 thin slice).

Rye is one of the higher-fructan grains and adds GOS too, so a thin slice is the low-FODMAP limit. A long-fermented rye sourdough is the more forgiving swap.

FODMAP subgroups to watch

Rye bread contains fructans, GOS that can drive SIBO symptoms.

Portion threshold

Fructans + GOS climb fast past 1 slice. Single typical servings stay in the rated range; larger servings push past the threshold.
