What should I know about lebensmittel mit histamin?

The question about histamine-rich foods is primarily relevant for individuals with histamine intolerance. Histamine is a biogenic amine naturally present in many foods, especially aged, fermented, or preserved products. Typical high-histamine foods include aged cheese (e.g., Parmesan, Gouda), sauerkraut, salami, tuna, wine (especially red), beer, and fermented soy products. Symptoms of histamine intolerance (headaches, flushing, diarrhea, palpitations) arise from an imbalance between histamine intake and breakdown, often due to reduced activity of the enzyme diamine oxidase (DAO). Some genetic tests (e.g., for DAO variants like rs10156191) may indicate a predisposition, but the evidence for clinical prediction is weak. Diagnosis is best made by a physician using a symptom diary and possibly blood DAO measurement. MyBody-X tests currently do not offer a specific histamine intolerance test; the existing DNA analyses (e.g., FOXO3, PPARG) have no direct relevance. Importantly, histamine intolerance is not an allergy, and individual tolerance thresholds vary greatly. An elimination diet under professional guidance is the gold standard. Evidence for dietary recommendations is mostly based on mechanistic studies and anecdotal reports, not large randomized trials. Therefore, caution is warranted: not every reaction to histamine-rich foods constitutes a true intolerance.
