Is spinach low FODMAP?
Why serving size is the thing to watch
Spinach cooks down a lot — a big handful of raw leaves reduces to a small spoonful once wilted. That means a "reasonable-looking" serve of cooked spinach, like a creamed spinach side dish or a dense spinach and cheese filling, can represent several times more actual spinach than it looks like. This is the pattern to watch for, more than spinach being inherently risky.
Raw vs cooked, baby vs mature
- Baby spinach, raw, in a salad — low FODMAP at typical serving sizes, straightforward.
- Lightly sautéed spinach as a side — still low FODMAP at a normal portion; just be mindful it's more concentrated than the same volume raw.
- Creamed spinach, spinach and ricotta fillings, or spinach-heavy dips — worth checking the actual quantity of spinach involved, since these preparations concentrate it further.

Frequently asked questions
Is baby spinach low FODMAP?
Yes — baby spinach is rated low FODMAP by Monash University at typical serving sizes, whether raw in a salad or lightly cooked.
Does cooking spinach change its FODMAP status?
Cooking itself doesn't change the FODMAP content, but it does change how much you're actually eating — wilted or sautéed spinach reduces dramatically in volume, so a "handful" of cooked spinach represents a much larger raw quantity than the same handful eaten raw. Large, concentrated cooked servings are where the fructan content can add up.
Is English spinach different from baby spinach for FODMAP purposes?
Mature English spinach is generally still low FODMAP at normal serving sizes, but as with baby spinach, a large concentrated serve (like a creamed spinach side dish) is more likely to push into moderate territory than a light handful in a salad.
