Sensitivity notes
Why histamine food checker matters
Histamine is a compound naturally present in many foods, especially aged, fermented, or preserved items. In sensitive individuals, excess histamine can cause headaches, flushing, hives, digestive issues, and other symptoms. Your body normally breaks down histamine, but some people have reduced capacity to do so.
- Focus on fresh foods - histamine builds up as food ages
- Cook and eat meals fresh; avoid leftovers sitting more than 24 hours
- Be cautious with fermented foods, aged cheeses, and cured meats
- Consider that stress and hormones can affect your histamine tolerance
- Some antihistamines or DAO supplements may help (consult your doctor)

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
