Histamine Intolerance: A Gut Problem in Disguise

Dr. Will Bulsiewicz

Bulsiewicz explains histamine intolerance — why certain foods (aged cheese, wine, fermented foods) cause headaches, flushing, and digestive distress in some people — and why the root cause is usually gut dysfunction, not the foods themselves.

Canon

•
The courage to reintroduce feared foods after gut healing requires trusting the science over the anxiety — many patients are trapped by fear of food reactions
Bulsiewicz describes patients who have healed their gut dysfunction but remain trapped by food fear: they are afraid to reintroduce foods that previously caused reactions. The courage to test reintroduction — risking a reaction — is necessary for full recovery.

Highlights

•
Histamine intolerance is usually a symptom of gut dysfunction, not a permanent condition — fixing the gut often resolves the food sensitivities
Bulsiewicz argues that most histamine intolerance is caused by reduced diamine oxidase (DAO) activity in a damaged gut lining. Treating the underlying gut dysfunction — through microbiome restoration — often resolves the histamine sensitivity without permanent dietary restriction.
