What is histamine intolerance?
Histamine intolerance occurs when there is a buildup of histamine in the body.
It is a chemical responsible for a few major functions:
- communicates messages to your brain
- triggers release of stomach acid to help digestion
- releases after injury or allergic reaction as part of your immune response
When histamine levels get too high or when it cannot break down properly, it can affect your normal bodily functions.
Which foods are high in histamine?
In general, fermented food products have the highest histamine content, while fresh foods have the least.
Fermented dairy products and meats, pickles, and alcoholic beverages are high in histamine.
Do antihistamines help histamine intolerance?
Antihistamines help in wearing off the effects of histamine temporarily.
They simply block the receptors that histamine molecules bind to, and prevent the interaction.
But once the antihistamines are removed from the system, histamine acts up and intolerance sets in.
What is a natural antihistamine? Does turmeric act as an antihistamine?
Vitamin C extract, butterbur extract, and probiotics are naturally available antihistamines.
Pineapples contain an enzyme called bromelain, which is known to show antihistamine properties.
Studies are underway to declare turmeric as an antihistamine.
It is observed to suppress the immune responses that occur.
Can antihistamines be taken every day?
Different brands of over-the-counter antihistamines function differently, so the frequency at which it can be taken needs to be checked with a clinician.

What are the symptoms of high histamine levels?
- Severe headaches
- Nasal congestions
- Irregular menstrual cycle
The above mentioned are common symptoms that indicate histamine levels are higher than normal.
How do I know if I have histamine intolerance?
The most common symptoms are related to the stimulation of the immune system, like itching, sneezing, hives, nasal congestion, and watering eyes.
Gastrointestinal symptoms like diarrhea and pain in the abdomen also occur.
Can histamine cause itchy skin?
Yes! Histamine is solely responsible for triggering immune responses that result in symptoms like itchy skin, rashes, swelling, etc.
Urticaria is a skin rash condition caused by histamine triggers.
Also called as hives, these ideally occur when the body responds to allergens.
How do you lower histamine levels?
One way to lower histamine levels is by blocking the absorption of histamine into the bloodstream.
Heart medications, antibiotics, malaria, and TB medications disrupt the enzymes that enable histamine absorption.
OTC painkillers like Aspirin and Diclofenac are also routinely used for lowering histamine levels.
Does magnesium lower histamine levels?
Magnesium significantly affects histamine metabolism.
Magnesium increases the degradation of extracellular histamine.
Reduced levels of magnesium cause a spurt in the production of histamine from histidine, its parent molecule.
Around 400-500 mg of magnesium, a day is studied to have improved effects.
What can I eat for breakfast on a low histamine diet?
Adding organic poultry, asparagus, beets, butternut squash, and fresh veggies and fruits like berries, cherries, and melons to your breakfast platter help in keeping the histamine levels under check.

What causes too much histamine in the body?
One cause of increased histamine is mastocytosis, a condition in which mast cells proliferate excessively and accumulate just under the epidermis.
These accumulations are hotspots for histamine releases.
Are the following foods high in histamine content?
Sadly, yes! Studies have shown that the consumption of chocolate increases histamine levels.
In normal situations, it will stop with being a tasty treat.
But when a person already suffers from a high content of extracellular histamine, chocolate simply adds to their woes.
Coconut contains stearic acid, which gets stored as fat molecules in the body, to be metabolized later.
But it has no direct effect on histamine release and is safe to consume.
Oatmeal has a very low histamine content and can be a great addition to your breakfast menu.
Coffee is high in histamines, and when consumed in large quantities can elicit symptoms of histamine intolerance.
Conditions related to histamine intolerance
Does histamine cause anxiety?
When histamine intolerance sets in, it causes dilation of blood vessels, drop in blood pressure, and other cardiovascular effects that predispose an individual to anxiety or panic attacks.
Can histamine intolerance cause anaphylaxis?
Histamine intolerance progresses with negative effects on the cardiovascular and immune systems.
This may be a cause for anaphylactic shocks that stem from hypersensitive immune responses.
Does histamine cause inflammation?
Histamine is said to trigger a set of chemical reactions that result in inflammation of the cells of the immune system.
An increase in the histamine levels will directly link to an inflammatory response.
Are chronic urticaria and histamine intolerance related?
Chronic urticaria is a long-lasting condition of rashes, hives, and itching on the skin.
This is established by histamine molecules constantly triggering cells of the immune system to sustain the immune response.
Are histamine deficiency and intolerance linked to paranoia, derealization, and nightmares?
There are no direct associations between histamine and paranoia, derealization and/or nightmares.
It has been linked to anxiety and panic attacks at the latest, but that is due to the other symptoms.
Mental illnesses are not related to histamine fluctuations on paper.
Does exercise increase histamine levels?
Interesting studies on exercise and histamine levels have been successful in establishing a link between the two.
During exercise, the body goes into a mode that favors vasodilation to increase the oxygen content being absorbed.
This is done by employing histamine molecules to trigger blood vessel dilation and related effects.
Although these do not stem from allergic reactions, the establishment of vasodilation is carried out using histamine molecules.
Does stress cause histamine release?
Stress stimulates the brain to start initiating relaxative mechanisms, like vasodilation to lower the blood pressure.
This is done with the help of histamine molecules, which trigger such mechanisms.
Thus, stress is found to increase histamine release in the body.
How does histamine affect the brain?
Studies have shown that histamine acts as a neurotransmitter by binding to different receptors across different parts of the human brain, thus causing varied effects on the human body.
Histamine is mainly responsible for keeping the brain ‘awake’ and alert.
It is also seen to influence eating habits, as it tends to decrease the urge to eat.
It is also hinted to help in reducing alcohol intake.
What is the difference between a mast cell disease and histamine intolerance?
Mast cell diseases are experienced as a result of an immune response towards an allergen.
However, histamine intolerance simply triggers the same response, in the absence of an allergen.
Xcode Life's Gene Allergy Report covers histamine intolerance, pet allergy, grass allergy, and 12+ categories.
