Fennel

Low histamine

Fresh fennel is low in histamine and free of known histamine-releasing properties, making it a well-tolerated vegetable.

Fennel — the bulb, fronds, and fresh seeds — is a fresh vegetable with no significant histamine content and no well-established mechanisms that interfere with histamine processing.

  • Distinguish from fennel seed spice — fresh fennel bulb is generally low-histamine; dried fennel seeds used as a spice may be better tolerated than many other spices, but some people with sensitivities find concentrated spice forms less predictable

  • Cooking doesn't change its status — whether roasted, raw, or braised, fresh fennel maintains its low-histamine profile

Fresh fennel bulb is a flavorful, versatile option that tends to work well for people watching their histamine load.
