What should I know about was nicht essen histaminintoleranz?

For histamine intolerance (HIT), avoid high-histamine and histamine-releasing foods: aged cheeses (Parmesan, Gouda), fermented products (sauerkraut, kimchi), alcoholic beverages (especially red wine, beer, sparkling wine), smoked or canned fish (tuna, anchovies, mackerel), processed meats (salami, ham), and certain vegetables (tomatoes, spinach, eggplant) and fruits (bananas, strawberries, citrus). Also chocolate, nuts, and vinegar can trigger symptoms. Important: HIT is not an allergy but a DAO enzyme deficiency. Tolerance varies individually; a strict elimination diet should be short-term and supervised by a doctor/dietitian to avoid nutrient deficiencies. A symptom diary helps identify personal triggers. Evidence for a blanket avoidance diet is moderate; many benefit from personalized adjustments. Caveat: Not everyone with symptoms has true HIT; other causes (mast cell activation, other intolerances) should be ruled out.
