Lemon juice
Lemon juice is a histamine liberator — its compounds may prompt your body to release stored histamine even in small amounts.
Citrus fruits like lemons sit firmly in the histamine liberator category, meaning they can trigger internal histamine release.
-
Liberation effect — it's not that lemon juice is high in histamine itself, but that citrus compounds appear to signal the body to release its own histamine stores
-
Small amounts add up — a squeeze of lemon in water, dressing, or cooking might seem minor, but if you're consuming multiple liberators throughout the day, it contributes to the overall load
Lime juice works in a similar way, so swapping one citrus for another typically doesn't change much.
