Histamine is a neurotransmitter involved in several of your body’s processes including your immune system and nervous system. As part of the immune system, histamine triggers your body’s inflammatory response when it sense irritants like pollen or dander. Histamine dilates your blood vessels and sends white blood cells to the site of inflammation.

Histamine is broken down by the N-methyltransferase enzyme in the central nervous system and by the diamine oxidase (DAO) enzyme in the digestive tract. Since DAO is responsible for metabolizing the majority of ingested histamines, a deficiency can contribute to symptoms of histamine intolerance.

Histamine intolerance occurs when you have a buildup or overproduction of histamine and are unable to fully break it down. If histamine builds up in the body, then troublesome symptoms can occur.

  • Irregular menstrual cycles
  • Difficulty falling asleep or staying asleep
  • Abdominal cramps
  • Dizziness
  • Anxiety

Low Histamine Diet

A buildup of histamine can happen due to an excess of your body’s natural production of histamine (produced by a species of bacteria found in our guts) and from overconsumption of histamine-releasing foods.

A low histamine diet will not completely solve a sensitivity or intolerance to histamine or address the root cause, but it can help reduce histamine in the body and possibly provide symptom relief. A combination of healing your gut and following a low histamine diet can resolve histamine intolerance for many people. Read more about histamine intolerance and how a low-histamine diet can help.

Again, going on a low-histamine diet may not cure the root cause of the intolerance, but it should help manage the symptoms. It’s always a good idea to check with your doctor to make sure that your symptoms aren’t the result of something more serious.

High Histamine Foods to Avoid

  • Alcohol and fermented beverages (especially red wine and kombucha)
  • Citrus fruits, bananas, avocado, and dried fruit. Strawberries can also be high in histamine
  • Pineapple and papaya
  • Fermented foods (kimchi, sauerkraut, yogurt, kefir, etc.)
  • Soured foods (sourdough bread, buttermilk, etc.)
  • Aged cheese and cow’s dairy products
  • Chocolate, cocoa, and cacao
  • Processed, cured, smoked, or leftover meats
  • Vinegar and vinegar containing foods (pickles, relishes, etc.)

  • Seafood (fin or shellfish, in any preservation such as canned, smoked, etc.)

While it can seem very restrictive to avoid high-histamine foods, there are still plenty of nutritious foods to enjoy.

Can I drink caffeinated coffee on a low histamine diet?

There is not a lot of research on coffee and histamine. But, at least one animal study showed an increase of histamine levels after consumption of caffeine. There is also anecdotal evidence that caffeine may reduce DAO levels, the enzyme responsible for breaking down histamine. So, it is best to ask your doctor or healthcare provider whether or not coffee is okay for you to drink.

Can I drink alcohol on a low histamine diet?

Probably not. This is because alcohol is another food that blocks DAO, which will inhibit the breakdown of histamine in your body. Alcoholic beverages are also usually fermented, which is another class of foods to avoid on a low histamine diet. As always, please discuss this issue with your healthcare provider.

Conclusions

A low histamine diet may help with symptoms of high histamine or histamine intolerance. When following a low histamine diet, choose foods that are low in naturally-occurring histamines and foods that are not fermented, cured, or processed in a way that increases histamines.

It is also important to note that the research is still developing regarding histamine intolerance and how to best treat it.
