Histamine intolerance describes an overload of a protein substance in the body that cannot be broken down. Specifically, it is a breakdown disorder of histamine – caused by the deficiency of the histamine-degrading enzyme diamine oxidase (DAO). Histamine passes through the intestinal mucosa into the bloodstream, from there into the organs where it irritates the cells.
