Histamine intolerance

Presumed set of adverse reactions

Histamine intolerance is a presumed set of adverse reactions to ingested histamine in food. The mainstream theory accepts that there may exist adverse reactions to ingested histamine, but does not recognize histamine intolerance as a separate condition that can be diagnosed. There is a common suspicion that ingested histamine in persons with deficiencies in the enzymes that metabolize histamine may be responsible for various non-specific health complaints, which some individuals categorize as histamine intolerance, still, histamine intolerance is not recognized as an explicit medical condition with that name in the International Classification of Diseases (ICD) Edition 11, or any previous edition. The scientific proof that supports the idea that eating food containing histamine can cause health problems is currently limited and not consistent.
