What Is Histamine And Histamine Intolerance?

Histamine is a chemical substance released by mast cells (a type of white blood cells) that helps regulate the body’s response to foreign substances. Simply put, your body releases histamine when it perceives something as harmful. While the body gets some amount of histamine from its own cells, histamine is also found in certain foods.

According to the Food and Health Organization of the United Nations and the World Health Organization, histamine-rich foods may cause histamine intolerance in sensitive individuals who have trouble breaking down this compound (2). Similar to an allergic reaction, the symptoms of histamine intolerance are (1):

Headaches
PalpitationⁱXSensations of pounding and racing heart felt in the chest, neck, and throat.
Redness
Skin inflammation
Nausea
Vomiting
Itchy skin
Rashes
Diarrhea

According to the American Academy of Allergy, Asthma, and ImmunologyⁱXA study of biology and medicine that deals with the medical research of immune systems. , there is no specific test for diagnosing histamine intolerance (3). So, doctors opt for an elimination diet. This means removing histamine-rich foods for 4 weeks and gradually adding them back. This allows your doctor to determine which food is triggering the symptoms.

How does a low-histamine diet benefit us? Let’s find out in the next section.

Benefits Of A Low-Histamine Diet

May Lower The Level Of Histamine In Your Body

The primary purpose of a low-histamine diet is to decrease the level of histamine in the body. Diamine oxidase is an enzymeⁱXProteins that aid in speeding our bodies' chemical changes or metabolism. that is responsible for breaking down histamine in our bodies. Studies have suggested that low levels of diamine oxidase (DOA) may increase the levels of histamine in the body (4). In another study, patients with histamine intolerance had lower DOA activity. The same patients when asked to go on a low-histamine diet with DOA supplements saw an improvement in the symptoms (5).

May Help Reduce The Symptoms Of Hives

A low-histamine diet may be instrumental in reducing the symptoms of hivesⁱXA typical skin rash caused by an allergic reaction and characterized by swollen and itchy bumps. . A study was conducted in 2018 to see the effect of a low-histamine diet on patients with chronic hives. The patients were prohibited from consuming histamine-rich food for 4 weeks. After 4 weeks, the researchers found a significant decrease in the histamine levels and severity of hive symptoms (6). Research also suggests that consuming a low-histamine diet for 3 weeks may be beneficial to patients with hives accompanied by gastrointestinalⁱXIt is of or pertaining to the gut and the stomach. symptoms (7).

May Help Manage Atopic Dermatitis

Similar to symptoms of histamine intolerance, the symptoms of atopic dermatitisⁱXA chronic skin condition that causes inflammation, dryness, and itching. may worsen due to the intake of histamine-rich food. A study conducted on a boy with atopic dermatitis found that a low-histamine diet is instrumental in the reduction of symptoms (1), (8).

May Reduce The Symptoms Of Irritable Bowel Syndrome

Eating a low histamine diet may reduce the symptoms of IBS. Research suggests that avoiding gluten-rich foods and fermented products may play an important role in reducing the symptoms of IBS (9).

A blogger shared her experience of following a low histamine diet for a week on her blog: “It took several days to get into the groove of eating this way, and then I noticed that I had lost some weight. I started weighing myself on Day 5 and by Day 6 had lost at least eight pounds (i).”

Even though a low-histamine diet has many potential benefits, it is highly recommended that you consult a doctor before going on this diet.

Today, due to limited evidence, it is difficult to quantify histamine levels in food. Factors such as storage time, addition of preservatives, and how old the food is can impact its histamine levels. Make sure you avoid foods labeled as “histamine liberators” as they are meant to help release histamine from other foods you consume. Here is a list of foods that may have higher levels of histamine (10):

Cheese, sour cream, buttermilk, and yogurt
Kimchi and sauerkraut
Pickles or pickled veggies
Kombucha
Salami, sausages, and fermented ham
Beer, wine, and champagne
Miso, tempeh, natto, and soy sauce
Sourdough bread
Tomatoes
Eggplant
Spinach
Frozen, salted, or canned fish such as sardines and tuna
Vinegar
Tomato ketchup
Avocado

Quick Tip

You may be more sensitive to some of these foods than others. Keep a detailed food diary and, after eliminating these foods, slowly reintroduce them one by one to identify those that trigger your histamine sensitivity.

While the above is a list of foods to avoid, below is a list of foods that are considered to be low in histamine.

Herbal teas
Quinoa, buckwheat, and rice
Chia, flax seeds, and hemp
Vegetables excluding spinach, eggplant, and tomato
Freshly cooked seafood and meat
Gluten-free products
Cooked eggs
Dairy-free products
Coconut products, such as coconut milk and coconut butter

Cons Of A Low-histamine Diet

Low histamine diet may lead to malnutrition

While limited studies indicate that a low-histamine diet can help reduce symptoms of various diseases, more studies are warranted to confirm that.

There is no scientific evidence currently that suggests that a low-histamine diet may improve quality of life in the long term.
A low-histamine diet may lead to malnutrition. Before you opt for it, it is recommended to consult a doctor/nutritionist for better understanding.
A low-histamine diet may be hard to sustain as it requires complete elimination of processed and canned foods. This may be hard for people who rely on these kinds of food for convenience.

Quick Tip

Check with your doctor for any nutritional supplements that you may need while on this diet, such as vitamin B6, vitamin C, zinc, and copper.

To Sum It Up

Histamine intolerance is a medical condition that is difficult to diagnose, and a low-histamine diet may be essential in tackling it. especially for individuals with compromised gut health and mast cell activation syndrome. Limited scientific evidence suggests that a low histamine diet may help in the reduction of symptoms of hives and atopic dermatitis. While cutting out fermented products and other selected foods may be beneficial for a while, it may lead to malnutrition in the long run. Before you opt for this diet, consult your doctor/nutritionist to plan a balanced diet that meets all your dietary needs.

Frequently Asked Questions

How can I lower my histamine levels quickly?

Taking antihistamines, corticosteroids, and DAO enzyme supplements may help lower your histamine levels quickly, especially if you suffer from DAO deficiency. DAO deficiency is a condition where the body lacks the DAO enzyme responsible for breaking down histamine. Therefore, consult your doctor before taking these medications.

Are potatoes high in histamine?

No, potatoes are not high in histamine.

What time of day is histamine highest?

Though the histamine levels keep fluctuating throughout the day, the body releases higher levels of histamine at night and the lowest levels in the afternoon. Excessive histamine may result in itching, difficulty breathing, and lack of sleep. Therefore, it is best to consume low histamine foods after evening.

Key Takeaways

Your body becomes histamine intolerant when it is unable to metabolize histamine.
This condition manifests in the form of an allergic reaction.
Studies suggest that diamine oxidase, a low histamine-breaking enzyme, may cause the intolerance.
Avoid fermented foods like pickles, kimchi, yogurt, etc., while on a low-histamine diet.
