Low Histamine Diet

What Is the Low Histamine Diet?

  • Histamine is a natural chemical present in our bodies and in certain foods. It is present in our skin, gastrointestinal tract, heart, lungs and brain. 

  • Someone with histamine intolerance may benefit from a low histamine diet. Consuming foods that are low in histamine helps to reduce the overall “load” of histamine in the body and may alleviate symptoms.

  • Histamine acts as a neurotransmitter (chemical messenger) in the central nervous system. It is also involved in the secretion of stomach acid. Histamine is produced by mast cells during immune responses to allergens. 

  • When histamine creates an allergic response, a person may experience typical allergy symptoms like congestion or runny nose, watery eyes, itchy skin rashes, sneezing, swelling, and inflammation or headaches. An abundance of histamine in the gut may cause gastrointestinal symptoms.

  • Histamine intolerance is when there is too much histamine in the body. This excess can be caused by:

    • Exposure to an allergen

    • Consuming high histamine foods

    • Impaired breakdown of histamine (due to genetic factors, certain medications, or poor gut health)

  • Histamine intolerance can manifest in a variety of ways including: diarrhea, constipation, stomach cramping, headaches, facial swelling, skin rashes, asthma, dizziness, anxiety, blood pressure changes, or fast/irregular heartbeat.[15]

  • Someone with histamine intolerance can benefit from a low histamine diet. Consuming foods that are low in histamine helps to reduce the overall “load” of histamine in the body and may alleviate symptoms.

Signs/Symptoms of Histamine Intolerance

Histamine intolerance can manifest in a variety of ways including [15]:

  • Diarrhea

  • Constipation

  • Stomach cramping

  • Headaches

  • Facial swelling

  • Skin rashes

  • Asthma

  • Dizziness

  • Anxiety

  • Blood pressure changes

  • Fast/irregular heartbeat

Recommended Foods

Low histamine foods include:

  • Fresh eggs, meat, and fish that is not leftover or thawed slowly

  • Fresh dairy products like milk, butter, or soft cheeses like mozzarella, ricotta 

  • Gluten-free grains

  • All fresh or frozen vegetables except those listed above 

  • Vegetable oils or animal fats

  • Fresh or dried herbs

  • Honey, agave syrup, stevia

  • Herbal teas

  • Non-dairy milk like almond or coconut

  • Most fresh or frozen fruits (some fruits don’t contain histamine but are limited on a low histamine diet. For a more complete list of foods for those following a low histamine diet, visit here

Foods to Avoid

Foods that are high in histamine include: [2]

  • Fermented or pickled foods like vinegar, yogurt, kombucha, kefir, sauerkraut, pickles, soy sauce, Worcestershire sauce

  • Alcohol, especially red wine

  • Leftover meat, fish, and seafood

  • Smoked, cured, and aged meats

  • Aged cheeses

  • Canned foods

  • Dried fruits and overripe fruits

  • Avocado

  • Certain vegetables like olives, eggplant, spinach, and tomatoes

A person on a low histamine diet may want to avoid foods that are metabolized using the DAO enzyme. We want the DAO enzyme to be available to break down histamine and not be otherwise occupied. The DAO enzyme will preferentially degrade the foods listed below, so those on a low histamine diet may way to avoid or limit these foods:

Other foods are not necessarily high in histamine but cause histamine to be released from our body’s own mast cells. These are known as histamine liberators and should be avoided or limited on a low histamine diet as well. Histamine liberators include:

Some foods also block the DAO enzyme, interfering with the breakdown of histamine.

  • Alcohol

  • Tea 

  • Energy drinks

Lifestyle Considerations for Low Histamine Diet

  • Histamine intolerance can be triggered by yeast/candida and mold. Candida and mold can lead to overall inflammation and GI dysfunction

  • Ask your doctor about testing for DAO deficiency and DAO gene polymorphism.

Supplement Recommendations for Low Histamine Diet

  • DAO enzyme supplements may be helpful

Low Histamine Diet in the Research

Effectiveness of Low Histamine Diet

  • A histamine-reduced diet improves symptoms of histamine intolerance. [7, 8, 11, 17]

DAO Supplementation

  • Oral supplementation with exogenous DAO enzyme from porcine kidney is also being used to enhance the intestinal capacity to degrade dietary histamine. [7, 8, 10, 11, 17, 20]

Low Histamine Diet and Asthma

  • Higher mean airflow obstruction and a trend for prolonged and more severe symptoms were observed among children with asthma that consumed a high histamine diet. Diet may have an active and direct impact on asthma symptoms. [9]

Low Histamine Diet Food List

  • Management of histamine intolerance is done with a low-histamine diet, although there is no consensus on the list of foods to be excluded. [10] 

  • A comparative review brought out the great variety in the type of foods that are advised against for histamine intolerant individuals. Only fermented foods were unanimously excluded. The presence of chemicals which may impair histamine degradation by the DAO enzyme at the intestinal level could partly explain the reason why certain foods were also frequently reported in low-histamine diets. [16]

Microbiome and Histamine Intolerance

  • The altered occurrence of Proteobacteria and Bifidobacteriaceae, reduced alpha-diversity as well as elevated stool zonulin levels suggest a dysbiosis and intestinal barrier dysfunction in histamine intolerant patients, which in turn may play an important role in driving disease pathogenesis. [17]

Histamine Intolerance Symptoms

  • When patients with histamine intolerance were surveyed, the most common and most serious reported symptom was bloating. Other commonly reported gastrointestinal symptoms were postprandial fullness, diarrhea, abdominal pain, and constipation. [18]

  • We show that intestinal and extra-intestinal non-celiac gluten sensitivity symptoms are very similar to those which can be found in histamine intolerance. [19]

  • The symptoms of histamine intolerance, although diverse and hence confusing, are remarkably similar to non-clonal mast cell activation syndrome. [21]

Histamine Intolerance and Children

  • The clinical picture of histamine intolerance in children is similar to that observed in adults apart from male predominance found in pediatric patients. In children, histamine intolerance most likely co-occurs with allergies and bowel diseases. [22]

The Bottom Line

This diet may be a challenge to follow for some people but it really depends on what the person is accustomed to eating. The biggest challenge is determining if a person’s symptoms are indeed due to histamine intolerance and the research agrees that diagnosis is non-standardized and difficult. For those that have histamine intolerance, the diet is widely accepted as an effective way to lower overall histamine in the body and keep symptoms at bay.

Diet Rating

Rating Scale: 1 - 5 Stars ★

We rate the quality and quantity of the research supporting the efficacy of the diet in improving symptoms as well as the Ease of Adherence, taking into account the cost, resources available, the time required, social acclimation to the diet including options available in restaurants and grocery stores which assist convenience and adherence

Ease of Adherence ★★★

This diet is relatively easy to follow, though the challenge is the lack of consensus on a complete “foods to avoid” list. Those that strictly follow the diet may have more of a challenge, though some people may benefit from less strict implementation of the diet.

Research ★★★★

There is an abundance of research to substantiate the use of a low histamine diet if histamine intolerance is suspected. If a low histamine diet proves beneficial, this is part of the criteria for diagnosis with histamine intolerance.
