Day 17: Is Histamine Intolerance Behind Your Weird Symptoms? June 2021

Day 17: Is Histamine Intolerance Behind Your Weird Symptoms? June 2021

Do you suffer from seasonal allergies? Me too! It’s miserable. 


Being allergic to pollen means your body releases lots of histamine in response to pollen. 


When your body has too much histamine, it can cause symptoms collectively known as histamine intolerance. As well as the usual allergy symptoms (sneezing, blocked nose, itchy and watery eyes etc.) you can get some other strange symptoms caused by histamine intolerance too. 


Too much histamine can be either due to excess production of histamine by your body (for example due to an allergy), or not being able to break down histamine very well.  OR… both!


Histamine intolerance symptoms impact many different system in the body, including:


  • Head: headaches & migraines
  • Mood: anxiety, irritability, brain fog
  • Stomach: acid reflux, nausea, stomach pain
  • Intestines: bloating, diarrhea, constipation
  • Heart: heart arrhythmia, dizziness
  • Sinuses: drainage, congestion
  • Skin: hives, itching, flushing,
  • Circadian Rhythm: sleep problems, insomnia, early waking


Most people with histamine intolerance have several of the symptoms above.


There are two enzymes that help to break down histamine in the body (DAO and HMNT), and you can have genetic variations that decrease the activity of these enzymes, meaning your body cannot break down histamine as effectively. 


Turns out I have variations in both these enzymes. 





Some bad news: it turns out wine can make allergies worse. If you’ve noticed you’ve been sneezing more after a glass of wine, histamine (and sulfites), found in wine, can be to blame as they exacerbate seasonal allergies. 


Both chemicals are also found in beer, spirits and some foods. Red wines are the biggest culprits when it comes to histamines, having between 60 to 3,800 micrograms per glass versus white wine, which has between 3 and 120. Gin and vodka are much lower in histamine than wine, so during allergy season it might be sensible to steer clear of the wine and have a gin with sparkling water and lemon instead!


Alcohol also decreases the histamine degrading enzyme DAO, so yet another reason why you might notice your symptoms are worse after a drink.


High-Histamine Foods


Foods like cured, smoked and tinned meats including bacon, salami and tuna are usually high in histamine. As are cheeses like stilton, cheddar, camembert and parmesan.


To reduce histamine, opt for fresh meat and fish and younger cheeses such as ricotta and mozzarella.


I love cured and smoked meats, cheese and wine! But I’ve noticed that I do react to foods like salami when my hayfever is also bad. I’m definitely feeling better at the moment because I have been working on optimising my nutrition this month and I’ve cut out most cheese.




Taking in the Good (write down three good things that have happened or that you have noticed)


  • Having lunch at the Beacon in Tunbridge Wells with my sister. 
  • Getting the site ready for my bee hive! 
  • Reading with my 5yr old before bed. 


What good things will you remember about today, the only Thursday 17th June 2021 we will ever have?


Until tomorrow,
