The Tolerance team will be at the at the NEC Birmingham all weekend.

Come say hi at stand B52. We’ll be offering:

🙋Free 1:1 Q&A sessions with (Saturday only)
💊Exclusive exhibition pricing on our diamine oxidase enzyme supplement jars
📋Take home low histamine food lists

See you there!

We're having a glow up!

You might notice our socials are a little barer than usual. Don't worry, we're still here, just refreshing our look.

While our grid gets a shake up, our diamine oxidase (DAO) you know and love remains unchanged.

Say yes, get Tolerance.

Diamine oxidase (DAO) is an enzyme found mostly in the gut, and its role is to break down histamine from the food and drink we consume.

Some people don’t produce enough DAO or their enzymes are damaged due to several reasons. This is what we call DAO deficiency.

DAO deficiency is often one of the main precursors to developing a histamine intolerance. Why?

If your body has insufficient or damaged DAO enzymes, it will likely lead to impaired breakdown of histamine. When this happens, excess histamine can pass through the gut and into our bloodstream, causing a 'histamine overload' throughout our bodies.

have written an article dedicated to DAO deficiency. Visit the Science section of our website to find out more.

Certain food and drink can affect the levels of histamine in the body, and it can help to be aware and consider two broad categories:

• Food and drink that contain high amounts of histamine.
• Food and drink that inhibit or reduce the effectiveness and/or the availability of the diamine oxidase (DAO), the enzyme that breaks down histamine.

Some high histamine food groups:

• Alcohol, including wine, beer and cider
• Fermented foods such as yoghurt and kimchi
• Matured cheeses
• Processed meat products
• Pork
• Aubergine and tomatoes
• Grapes
• Shellfish and oily fish

Some diamine oxidase (DAO) enzyme inhibitor food groups:

• Black tea, green tea and coffee
• Chocolate
• Avocado, banana, citrus fruit and strawberries
• Lentils
• Pistachios
