Mashed potato

Moderate FODMAP (Caution)Potato + milk + butter

Is mashed potato low FODMAP?

Mashed potato is moderate FODMAP, safe in limited portions (Potato + milk + butter).

Potato and butter are fine; regular milk adds lactose, and restaurant versions often add garlic. If you made it yourself with lactose-free milk and no garlic, log the homemade version instead of this one.

FODMAP subgroups to watch

Mashed potato contains lactose, fructans that can drive SIBO symptoms.

Portion threshold
