What to know 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.
Watch for
- 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
