The role of histamine
Histamine is an incredible natural chemical that helps regulate immune reactions, gut function and central nervous system processes. It’s also the chemical responsible for common allergy symptoms like swelling, itching, mucus and sneezing.
Believe it or not, allergy symptoms are designed to help our body defend itself against pathogens. (For instance, a runny nose reduces further exposure to airborne substances.) So, histamine forms an integral part of a healthy inflammatory immune response. However, for some people, histamine levels can ‘build up’ in the body, sparking new (or exacerbating existing) allergy symptoms.
What is histamine intolerance?
Typically, there are natural enzymes that help break down and maintain histamine balance in the body. But, if your body cannot break it down properly, histamine levels begin to build up, which leads to a condition known as histamine intolerance.
Why does histamine build up in the body?
We produce more than we need
An overproduction of histamine may be due to:
We don’t break histamine down effectively
Our intestines produce certain enzymes that help breakdown and balance histamine. So, when our enzyme levels (particularly DAO) are compromised, it can increase histamine levels and may even spark histamine sensitivity.
DAO levels are directly influenced by our diet, particularly our consumption of zinc, copper, and vitamins B6 and C. So, it’s important to ensure we get enough of these key nutrients. They can also be affected by some medications, alcohol consumption, genetics and hormone imbalances. So, consult with your health care practitioner If you suspect you have histamine intolerance.
We consume too many histamine-rich foods
It’s usually only once your histamine levels are high, and you have difficulty breaking it down, that high-histamine foods become a challenge. Watch out for aged or fermented foods, such as cured meats, wine, blue cheese, yoghurt and sauerkraut. Other culprits include citrus fruits, strawberries, dried fruits, tomatoes, eggplant, anchovies, chocolate, tea, yeast and some preservatives. Some foods also encourage our bodies to release histamine (even though they don’t contain much themselves). Bananas, pineapples, tomatoes, peanuts, egg white and shellfish all fall into this category.
