Overview
About Fennel bulb
Fennel bulb, the crisp aniseed vegetable, is a high-FODMAP food because of its fructan content, and it is also high in salicylates.
A generous serving of raw shaved fennel delivers the biggest fructan hit and is a common cause of bloating and gas for people with IBS or fructan intolerance, though small cooked portions are tolerated more easily. On every other front it is clean: low in histamine, with no nickel or glutamate concern.

How Fennel bulb scores
Watch for
What trips people up
- High in fructans, so a large portion of raw fennel is a frequent FODMAP trigger for bloating and wind
- High-FODMAP by volume: small serves are usually fine, but a whole shaved-fennel salad tips it into trigger territory
- High in salicylates, relevant if you are salicylate-sensitive
- Oxalate content is not well established for fennel bulb, so there is no firm claim to make there

FAQ
Common questions about Fennel bulb
Is fennel bulb high FODMAP?
It is high-FODMAP in larger servings because of its fructans, but small portions are gentler. A modest cooked amount is often tolerated, while a big raw fennel salad is the version most likely to cause symptoms.
Does fennel make you bloated?
It can. The fructans in fennel bulb ferment in the gut and produce gas, so people with IBS or fructan intolerance often bloat after a large serving, especially when it is eaten raw and in quantity.
Is fennel bulb low in salicylates?
No. Fennel bulb is high in salicylates, so if you are salicylate-sensitive it is worth limiting, and worth remembering that the aniseed flavour comes with a salicylate load rather than a clean profile.
