How it can benefit you and what to eat [Video]

From headaches to itchy skin and nausea, histamine intolerance can make life uncomfortable. A low-histamine diet can help.

Histamine plays a role in our immune and digestive systems, and helps our neurological function.

Our body naturally produces this chemical, but it can also be found in food.

Some people are less tolerant of histamine – they have too much of it in their system.

Dietitian Nicole Dynan says this may be because they lack an enzyme called diamine oxidase (DAO), which breaks down histamine in the body.

“People may lack DAO due to interference by medications or if they have a gut disorder. Some foods also block the release of DAO,” says Nicole, of Dietitians Association of Australia.
