These foods are, among others:
Raw or pasteurized milk and dairy products.
Citrus fruits, strawberries and banana.
Seafood, oily fish and fish sauces.
Raw cured sausage such as spiced sausage, chorizo or bacon.
Some vegetables such as tomatoes, spinach or aubergines.

*Alcoholic drinks contain, to some extent, histamine or other biogenic amines, and furthermore, alcohol inhibits DAO activity impeding histamine degradation and metabolization.
