Histamine Intolerance
Histamine intolerance is reduced tolerance to dietary histamine in aged and fermented foods. Short guided trials and medical workup beat long random restriction.
Histamine intolerance is difficulty clearing dietary histamine—found in aged cheese, wine, fermented foods, and leftovers—leading to headaches, flushing, or gut symptoms in sensitive people. It is not a universal gluten-style villain; diagnosis overlaps with allergies and mast cell issues.
Low-histamine trials should be short and guided.
Common questions
-
Should everyone avoid fermented foods?
No—most people tolerate them well. Avoid only if consistent symptoms link to high-histamine meals and a clinician supports the approach.
