Shiitake mushroom
Is shiitake mushroom low FODMAP?
Shiitake mushroom is moderate FODMAP, safe in limited portions (Safe to a small handful (~17g)).
Shiitake carry mannitol, so keep fresh ones to a small handful and dried ones to about 2 caps. Larger amounts climb high. The deep savory flavor goes a long way, so a little still reads as plenty in a stir-fry or broth.
FODMAP subgroups to watch
Shiitake mushroom contains mannitol that can drive SIBO symptoms.
Portion threshold
High in mannitol above ~17g. Single typical servings stay in the rated range; larger servings push past the threshold.
SIBO note
Watch this one for IMO (formerly methane SIBO). The fermentation pattern of shiitake mushroom tends to feed this specific bacterial pattern more than other SIBO types.
