Overview

About Scallions

Scallions are a low-FODMAP win hiding inside a high-FODMAP vegetable.

The white bulb is high in fructans, the same onion-and-garlic FODMAP that bloats and cramps sensitive guts, but the green tops are low-FODMAP and Monash-cleared. That is the whole trick: cook with the green part, discard or set aside the white bulb, and you keep the onion flavor without the fructan hit.

How Scallions scores

Watch for

What trips people up

  • The white bulb is high in fructans, the same FODMAP found in onion and garlic, so it can bloat, cramp and gas a sensitive gut
  • The green tops are low-FODMAP: using only the dark-green part is the standard way to get scallion flavor safely
  • Moderate overall FODMAP and a mild histamine liberator, so raw and in quantity is harder than a small cooked garnish

FAQ

Common questions about Scallions

Are scallions low FODMAP?

Partly. The green tops of scallions are low-FODMAP and Monash-cleared, but the white bulb is high in fructans, the same FODMAP as onion and garlic. So scallions are low-FODMAP only if you use the green part and leave out the white bulb.

Can I eat green onions with IBS?

Usually yes, if you stick to the green tops. The dark-green portion gives you onion flavor without the fructans that trigger bloating and cramps, so it is one of the few ways FODMAP-sensitive people can keep an onion note in cooking. Save the white bulbs for infusing oil, which you then discard.

What part of a scallion is high in FODMAPs?

The white bulb at the root end. It concentrates the fructans, just like a regular onion, while the green tops are low. Slicing off and discarding the white bulb is the simplest fix, and using the greens keeps a dish IBS-friendly.
