Is Oat Milk Low FODMAP?

Updated · Dairy alternatives
Depends on portion or type

It depends on the brand and portion. Some oat milks are tolerated in small servings, but the result varies.

Main FODMAPs: Varies by brand

Why

Oat milk is made from oats and water, and oats contain small amounts of fructans and GOS. Many brands also add sweeteners, thickeners, or fibers, so the FODMAP content differs from one product to another.

Good to know

  • Check the label for added inulin, chicory root fiber, or fruit juice concentrates.
  • Barista blends and flavored versions often contain more additives than the plain kind.
  • If you want to try it, start with a small serving and see how you feel.

Tips and swaps

  • Lactose-free milk
  • Unsweetened almond milk
  • Rice milk
