Alcohol
Another dietary source that contains high histamine content is alcohol. Both beer and wine are loaded with a lot of this substance. Normally the body can produce DAO, an enzyme that can break down histamine. However, excessive consumption of alcoholic beverages would inhibit the production of this enzyme. That is why heavy drinkers tend to be at higher risk of histamine intolerance when the element builds up in their bodies after an extended period. The exact histamine levels can vary in different alcoholic drinks. Red wine tends to have the highest amount compared to beer and white wine. [3]
