Ouzo
As a distilled spirit, ouzo's main histamine issue is alcohol blocking the enzyme your body uses to clear histamine.
Ouzo is a distilled spirit, so it doesn't carry much histamine directly — but alcohol itself interferes with DAO, the enzyme your body relies on to break down histamine from food and drink.
-
DAO blocking — even a small amount of alcohol can slow histamine clearance enough to let levels build up, especially if you've eaten histamine-rich foods alongside it
-
Anise compounds — ouzo's characteristic anise flavoring may cause reactions in some people, though this is more about individual sensitivity than a well-established histamine mechanism
Pairing ouzo with lower-histamine foods may help reduce the overall load on your system.
