Whether you’re suffering from high levels of histamine or you need to follow a low histamine diet, here’s a list of the best Natural Antihistamine Foods that may help symptoms.

What is Histamine and What Does it Do?

Histamine is a chemical that acts as a messenger in the body. It has three main purposes:

  1. It forms part of our immune response to allergens or injuries,
  2. It carries messages between the brain and nervous system,
  3. It stimulates the production of stomach acid to help us break down and digest food.

The problem with histamine is that too much of it can build up in the body’s tissues. This can be caused by various things – either too much exposure to histamine through food or environmental factors, an inability to break it down properly, or the release of excess histamine after an infection.

The build-up of histamine is known as histamine intolerance.

When histamine levels are too high, the functions that histamine is meant to support tend to become problematic. Learn more about how to naturally lower histamine levels.

The immune system, for example, may begin to perceive harmless substances like dust or certain foods as harmful. It will then release extra histamine and other chemicals into the bloodstream, affecting organs like your nose, eyes, throat, lungs, skin, or digestive system.

The results are the type of symptoms that we typically associate with allergic reactions, such as sneezing, wheezing, hives, and digestive problems. 

What Does Antihistamine Mean?

An antihistamine is something that curbs the effects of histamine on the body, bringing bothersome symptoms under control.

When you think of “antihistamines” you probably think of medications, and there are certainly many over-the-counter and prescription drugs that can block some of the negative effects of histamines.

But it is also possible to control the symptoms of histamine intolerance with certain foods. 

Whilst all antihistamine foods naturally contain very low levels of histamine, there are other ways in which they are helpful. 

Some, for example, can help boost the production of an enzyme called diamine oxidase (DAO). DAO is produced by the body and its main function is to keep histamine levels within a healthy range. Eating foods that can stimulate DAO production will help clear excess histamine more quickly.

Conversely, some foods should be avoided in an antihistamine diet because they block DAO, or because they actually promote histamine release. These foods are known as histamine liberators

Foods to Avoid and Unsuitable for a Low-Histamine Diet

Foods That are High in Histamines

You may need to avoid these high histamine foods until your symptoms are under control.

  • Fermented foods (such as kombucha, yogurt, kimchi, and sauerkraut)
  • Preserved meats
  • Aged cheese
  • Alcohol (especially red wine)
  • Avocado
  • Spinach
  • Fresh fish and shellfish (if frozen immediately after being caught, frozen fish is lower in histamines)
  • Bone broth (because of the lengthy cooking time needed to produce it)

Foods That Can Trigger the Release of Histamines

  • Cocoa
  • Chocolate (although white chocolate is often well tolerated)
  • Peanuts, cashews, and walnuts
  • Banana
  • Tomatoes
  • Citrus fruits
  • Strawberries
  • Dried fruits (these often contain sulfites or other preservatives that may trigger histamine release
  • Legumes
  • Vinegar

Foods That Block the Production of DAO (Should Be Avoided)

  • Alcohol
  • Tea (including black, green, and yerba mate)
  • Energy drinks

Other Tips

As much as possible, try to cook only fresh ingredients (except for fish which can be higher in histamines when freshly-caught). This means avoiding doing a large weekly shop and aiming to buy your ingredients as and when needed. This is because fresh foods are relatively low in histamine, but the content increases with time.

It’s also a good idea to look for organic produce, in order to avoid any pollutants that may trigger histamine-related reactions. See my related article for how to eat more organic.

There is also evidence to suggest that the cooking methods you use can make a difference to the histamine content of your food. A 2017 study showed that frying or grilling foods increased their histamine levels, whereas boiling them either didn’t affect them or even reduced them.

Conclusions

The symptoms caused by a build-up of histamine can be uncomfortable. Whilst antihistamine medication can temporarily control them, making adjustments to your diet may be an even better solution.

Consuming the right foods gives you some control over how much histamine is released by your body and how quickly it is cleared. These benefits make an antihistamine diet more of a long-term solution and one that may bring you significant relief.
