Glossary

A group of chemical substances resulting from the decarboxylation of amino acids. Histamine is the best-known biogenic amine.

Substances that reduce the activity of the DAO enzyme, which worsens the breakdown of histamine.

The main enzyme responsible for breaking down histamine in the body. Its deficiency is related to HIT.

Temporary exclusion of foods with a high histamine content to determine the body's reactions and subsequent gradual inclusion.

The process by which microorganisms convert substances. It is key in HIT because it increases the histamine content of food.

A biogenic amine formed during the breakdown of proteins, plays a role in immune reactions and digestion.

The inability of the body to properly break down histamine, which leads to its excessive accumulation and manifestations.

Substances that release histamine from cells, worsening the symptoms of HIT.

An amino acid that is converted to histamine in the body. Its excess or poor processing can worsen HIT.

A biogenic amine produced by protein breakdown, similar to histamine, can worsen HIT symptoms.

A build-up of histamine in the body from various sources that exceeds tolerance and triggers symptoms.

Limiting histamine-rich foods and histamine-releasing substances for people with histamine intolerance.

A biogenic amine formed during the breakdown of proteins can worsen the symptoms of HIT.

The gradual inclusion of foods with a higher histamine content back into the diet after the elimination period.

DAO enzyme supplementation for better histamine breakdown in histamine intolerance.

DAO enzyme supplementation for better breakdown of dietary histamine in people with HIT.

An independent non-profit organization (Schweizerische Interessengemeinschaft Histamin-Intoleranz) that specializes in research, education and support for people suffering from histamine intolerance (HIT) and related disorders of mast cell metabolism.

A biogenic amine similar to histamine that may exacerbate HIT symptoms in susceptible individuals.

Immune system cells that release histamine and other mediators in response to HIT triggers.
