DAO Deficiency

New Study Finds DAO Deficiency Accounts for Over 70% Of All Histamine Intolerance

November 21, 2015  |  Histamine Intolerance  |  24 Comments

A study just published on 16 November 2015 has confirmed that DAO deficiency remains the leading cause of histamine intolerance.

The study was conducted using 14 patients from one Italian hospital clinic. The participants were selected from past patients whom had benefited from a low histamine diet.

Patients had a blood DAO test, and 10 of the 14 study participants, had on average less than one fifth of a healthy person’s DAO.

The Lab Test For Histamine Intolerance

One of my current frustrations is that 23andMe™, and online report readers, are used to self-diagnose rather than get the lab test for histamine intolerance.

Here is a report from a popular online 23andMe™ report reader of the “DAO” snps from one of my clients.

You could be forgiven for thinking that…

MTHFR? Vitamin C Can Boost Your Folate by 50%

August 4, 2015  |  Blog, Histamine Intolerance  |  18 Comments

Do you have mutations of MTHFR? Vitamin C can boost your folate by 50%.

Folate is a critical nutrient for protecting DNA and in homocysteine methylation. Yet folate is very fickle.

If you have an MTHFR mutation, in the presence of oxidative stress, then folate can become unstable and wreak havoc.

However, at least three small human studies, have shown that vitamin C acts to stabilise folate. Not only that but it helps to absorb it even with a fickle C667T MTHFR polymorphism.

A Bio-Individual List of Histamine Inhibitors

This blog post outlines a list of bio-individual histamine inhibitors. It is a companion post for my previous post on the bio-individual triggers of histamine intolerance.

Histamines are a natural chemical in plants, animals, and humans. The body needs histamines to perform critical functions.

The body was designed to be in a state of homeostasis so that the supply of histamine meets the body’s metabolic needs.

Excessive amounts of histamine are normally de-activated by diamine oxidase (DAO), histamine methyl transferase (HNMT), and monoamine oxidase (MAO).
