Food Sources of Histamine
Histamine occurs in food as a result of microbial enzymes converting the amino acid histidine (present in all
proteins) to histamine. All foods subjected to microbial fermentation in the manufacturing process contain
histamine. Included in this category are cheeses, fermented soy products, other fermented foods (e.g.
sauerkraut), alcoholic beverages, and vinegars.
Foods exposed to microbial contamination also contain histamine in levels determined by the extent and rate of
action of the microbes. Histamine levels reach a reactive level long before any signs of spoilage occur in the
food. This characteristic has important implications in fin fish, where bacteria in the gut are particularly active
in converting histidine to histamine. The longer the fish remains ungutted, the higher the levels of histamine in
the flesh.
Some foods such as eggplant and spinach contain high levels of histamine naturally. In addition, a number of
food additives such as azo dyes and preservatives mediate the release of histamine.
Some of these chemicals such as benzoates occur naturally in foods, especially fruits, and may have the same
effect as the food additive in releasing histamine.
The histamine restricted diet excludes all foods known to contain high levels of histamine or to contain
chemicals that can promote the physiological release of histamine.

The foods most commonly reported to induce urticaria are shellfish, fish, egg, nuts, chocolate, berries, tomatoes,
cheese, milk, and wheat.
Foods reported to release histamine directly from mast cells are uncooked egg whites, shellfish, strawberries,
tomatoes, fish, chocolate, pineapple and alcohol.
Foods containing histamine—Aged protein containing foods and fermented foods commonly have increased
histamine levels.
Foods reported to be high in histamine are fermented cheeses (e.g. Camembert, Brie, Gruyere, Cheddar,
Roquefort, Parmesan), brewer's yeast, shellfish, many fin fish, canned fish, tomato, spinach, red wine
(especially Chianti), beer, unpasteurized milk (e.g., cow, goat or human milk), chicken, dry pork sausage, beef
sausage, ham, chocolate, fermented soy products, and all fermented vegetables, such as sauerkraut.
