Low & High Histamine Foods List – Histamine Intolerance Guide

Histamine is an inflammatory compound that helps your immune system fight infections. It is produced when you are exposed to an allergen and your bodies attempt to get rid of it.

This compound is also a component of stomach acid, that is what helps you break down food in the stomach. Additionally, histamine is involved in your central nervous system and your immune system.

Histamine intolerance usually results from a disequilibrium of the capacity for histamine degradation and accumulated histamine. Diamine oxidase (DAO) is the primary enzyme that is needed for the metabolism of ingested histamine.

Statistics

About 1% of the population experiences histamine intolerance, either due to a lack of enzymes necessary to remove histamine from the system or unusually high levels of histamine in the body.

Causes

Common factors that interfere with diamine oxidase levels include the following:

  • temperature extremes;
  • alcoholic beverages;
  • injury or trauma;
  • low oxygen states;
  • chronic emotional stress;
  • a deficiency in vitamin C, vitamin B6, zinc, or copper;
  • liver conditions;
  • intestinal conditions that compromise the gut lining.

In addition, many prescription drugs may interfere with DAO, such as:drugs

  • tuberculosis medications;
  • airway medications, like – theophylline;
  • malaria drugs;
  • heart medications;
  • gastroesophageal reflux disease;
  • antibiotics;
  • nausea;
  • antidepressants;
  • over-the-counter and prescription NSAIDs and painkillers, like – naproxen, diclofenac (Voltaren), indomethacin (Indocin), or acetylsalicylic acid (aspirin);
  • gastrointestinal medicines;
  • antipsychotics;
  • muscle relaxants;
  • diuretics.

Diamine Oxidase Blocking Foods List

Diamine oxidase is the main enzyme for the metabolism of ingested histamine.

When histamine is not broken down by the body and is absorbed, it can lead to a variety of symptoms.

DAO-blocking foods and drinks include:

  • green tea;
  • alcohol;
  • mate tea (the national drink of Argentina that is also known as cimarrón or chimarrão);
  • black tea;
  • energy drinks.

Symptoms

Histamine intolerance can mimic a variety of the symptoms of an allergic reaction and may range from mild to severe.

Home Remedies

There are some natural remedies that can help improve diamine oxidase activity.

Butterbur

Butterbur is a natural antihistamine that has been used for centuries in Europe. 

In randomized clinical trials, butterbur has been shown to work as well as Allegra, Claritin, and Zyrtec.

Butterbur is sold in a number of forms, including:

  • gels;
  • extracts;
  • tinctures;
  • powders;
  • capsules.

Note – if you have a ragweed allergy, butterbur is cross-reactive and should be avoided.

Ubiquinol CoQ10

Ubiquinol is a reduced version of the coenzyme.

It is used for energy production and is important for a variety of processes, including diamine oxidase activity.

Holy Basil

Holy basil (scientific name – Ocimum tenuiflorum) is an aromatic perennial plant in the family Lamiaceae.

It is a natural antihistamine as well as it helps with anxiety, emotional stress, and adrenal dysfunction.

Quercetin with Bromelain

Quercetin is an antioxidant found in many fruits and vegetables. Bromelain is an enzyme found in pineapple and papayas. When quercetin is mixed with bromelain, it becomes an even more potent diamine oxidase-booster.

Note – quercetin is not well absorbed, therefore, it should be taken several times throughout the day and about twenty minutes before a meal.

Probiotics

Probiotics are live yeasts and bacteria that have numerous health benefits.

Two species that are especially helpful for histamine intolerance include Bifidobacterium longum and Lactobacillus rhamnosus.

Nigella Sativa Oil

This oil comes from black cumin seeds. These seeds have been widely used for hundreds of years in the treatment of different ailments throughout the world.

Nigella sativa oil is helpful if you are dealing with nasal congestion due to histamine intolerance.

Vitamin C

Vitamin C is a water-soluble vitamin which is found in many types of plant-based foods. It is necessary for the development, growth, and repair of all body tissues.

In addition, this vitamin is the co-factor for alcohol dehydrogenase, a type of enzyme which breaks down histamine.

Note – it is suggested to supplement with about 2 grams a day.

Riboflavin

It is required to help make FAD (flavin adenine dinucleotide), the co-factor for diamine oxidase. Hence, it is thought to be helpful with histamine intolerance.

DAO Supplements

These supplements are designed to enhance the breakdown of histamine within the contents of the digestive canal and to increase the diamine oxidase in the digestive tract.

This actually means that supplementing with the diamine oxidase enzyme only helps you to break histamine down which you are consuming.

Note – the supplements are derived from a porcine source, therefore, if you are allergic to pork, it is best to avoid them.

Prevention

  • folic acid (the synthetic form of folate) increases histamine levels, hence, it should be avoided by individuals whose histamine levels are high;
  • avoid fermented foods, like wine, cheese, fermented sausages, vinegar, sauerkraut, and soy sauce as they naturally contain high levels of histamine;
  • cut down on additives as they can contribute to histamine being released in your body;
  • take steps, like increasing water and dietary intake, to prevent constipation;
  • ensure your food is as fresh as possible and throw out the left-overs in the fridge;
  • avoid eating overripe vegetables and fruits.
