Potato flour is a starchy tuber flour.

Low-FODMAPYes

Potato flour used as a small baker's percentage is low FODMAP.

The short answer
Potato flour is dried whole potato. Potato flour is vegan, and the tuber has no gluten. It is not keto. It is low FODMAP in a normal thickening amount. It tastes of potato and holds water, which is why a little of it keeps a gluten-free loaf from crumbling.
Use in moderation

Potato flour is a food, not an E-number. It is gluten-free. It is a nightshade, which matters to people who avoid those plants. It is not the modified starch listed as an additive.

Daily limit: Experts haven’t set a number because normal food amounts are far below any level of concern.

What is it?

The potatoes are cooked, dried and milled. The powder is heavy and speckled if the skins were left on. A teaspoon changes a dough. A cup used like wheat flour makes a gummy loaf.

Where it comes from: Potato flour is whole potato, cooked, dried and ground, skin and all. Potato starch is only the starch washed out of the raw tuber. They are stocked side by side and they do not bake the same way.

Why it’s in food

  • Holds a gluten-free loaf
  • Thickens a stew
  • Extends a flatbread
  • Adds potato flavor
