The Histamine Intolerance and Diamine Oxidase Connection

A new study by Maintz and Novak et al concludes that the histamine intolerance and diamine oxidase connection alone does not explain histamine intolerance (HIT). Previously, genetic mutations in DAO, were hypothesised to be the sole cause.

HIT is the result of an imbalance between histamine and the capacity for histamine…

Why Olive Oil (And A Paleo Diet) Increases DAO

This blog post addresses why olive oil (and a paleo diet) increases diamine oxidase (DAO) and helps reduce the symptoms of histamine intolerance.

DAO

The intestinal mucosa is a protective layer in the gut that contains a wide range of enzymes used in digestion and nutrient absorption. One of these enzymes is DAO.

DAO protects the body against an excessive buildup of histamines by degrading both ingested and bacterial histamine.

The amount of DAO synthesised can be reduced due to a genetic mutation (DAO deficiency) but it is nutrients which make it bio-available. This means that what we eat will determine whether available DAO is transported into the gut and bloodstream.

This is not speculation. A study examined each of the key nutrients and here is what they found:
