Celery
Fresh celery is low in histamine, though it is a known allergen for some people — a separate issue from histamine sensitivity.
Celery doesn't contain significant histamine and isn't known to release or block histamine breakdown in the body.
-
Freshness still counts — celery that's gone limp or is past its prime is worth replacing, as degradation over time can slowly affect how any vegetable sits
-
Allergy vs. intolerance — celery is one of the top 14 allergens in Europe, but a celery allergy is distinct from histamine intolerance and involves a different immune response
For histamine purposes specifically, fresh celery is generally considered a safe, everyday option.
