Most likely, you’ve heard about antihistamines. These medications reduce the symptoms of allergies. But what are histamines, though?
The immune system produces these substances. Histamines function similarly to the club bouncers. They assist the body in eliminating an irritant, in this case, an allergy trigger, or “allergen.”
Your immune system uses histamine as a signaling molecule to communicate with other cells. Although histamine serves several purposes, its primary job is to trigger allergic and anaphylactic reactions.
Your body’s response to a foreign protein is an allergy. These proteins, sometimes referred to as allergens, are generally benign. When you’re allergic to a specific protein, the immune system starts to react too strongly in your body.
A series of responses triggers the release of histamine, which leads to the development of allergy symptoms. Usually, these symptoms only affect one part of your body. The majority of your body is affected by anaphylaxis, which is a severe immunological reaction. Anaphylactic shock can be very fatal.
In this article, we will discuss several low-histamine meals that are safe, filling, and simple to make, which will improve your health without sacrificing taste.

What Is a Low-Histamine Diet?
“Histamine is known as a chemical substance in mast cells, which is a certain type of white blood cell. Histamine helps your immune system respond to allergy triggers,” registered dietitian Amanda Igel, MS, RD, LD explains. “If you have an allergy to certain food, for example, the histamine gets released by these immune cells to protect the body from what it perceives as a threat.”
In an attempt to protect your body against an allergen, histamine transmits a variety of signals. It constricts your gastrointestinal (GI) tract and airways while also widening your blood vessels. Additionally, you begin to produce mucus, which is why your nose is runny.
According to Dr. Amy Burkhart, M.D., R.D., a registered dietitian and integrative medicine physician in Napa, California, the histamine-restricted diet is an eating plan that focuses on minimizing the total amount of histamine consumed daily by eliminating particular foods that contain higher levels of histamine. Although you cannot entirely avoid histamine in meals, choosing foods with lower levels of the chemical can help you reduce your overall histamine intake.
Those who cannot break it down quickly enough can use this to prevent histamine overload and lower their chance of developing a histamine intolerance. Regretfully, this diet won’t eliminate your aversion.
The diet includes avoiding meals and beverages that inhibit the DAO enzyme’s function, as well as choosing low-histamine food. According to Dr. Burkhart, “the DAO enzyme is comparable to lactase, which aids in the digestion of lactose, the sugar found in milk.” When consuming dairy products, people who are lactose intolerant may steer clear of meals that contain lactose or take an additional lactase supplement.
High-Histamine Foods to Avoid
You should avoid foods that have high levels of histamine or trigger its production when following a low-histamine diet. Although a comprehensive list is not necessary, knowing which frequent high-histamine culprits to avoid will help you manage your symptoms effectively.
Histamines are naturally present in some foods. Others cause your white blood cells to produce histamine even when they don’t have much of it. Both types of foods can cause your body to make too much histamine if you have histamine intolerance.
In most cases, foods that are fermented, aged, or heavily processed contain more histamine compared to fresh options.
Documented foods with increased histamine levels include:
- Alcohol
- The eggplant
- Sauerkrauts is a pickled or canned food.
- Cheese that has aged
- Products made from smoked meat, such as sausages, ham, and salami.
- Shellfish
- Nuts kept for a long time, such as peanuts, cashew nuts, almonds, and pistachios
- Chocolates and other goods made with cocoa
- Rice vinegar
- Prepared meals
- Salty snacks and confectionery that contain artificial coloring and preservatives
Many fruits can cause the production of histamine even when they don’t contain a lot of it. Some ingredients may resemble histamine, which can exacerbate symptoms. Thus, think about avoiding:
- A banana
- A pineapple
- Papaya
- Citrus fruits, including oranges, lemons, and limes
- Strawberries
- Cherries

Tips for Cooking and Storing Low-Histamine Foods
Managing histamine intolerance entails adherence to specific cooking and storing techniques. Ultimately, freshness and timing are of the utmost importance when it comes to histamine content in food. Histamine levels in the food can also increase over time, particularly during post-cooking and consumption.
When Managing Meats: The longer you leave meat and fish out before cooking, the more histamine they will contain. Freezing halts this histamine manufacturing process. Cook the meat immediately or freeze it, then defrost and cook it later when you return from the store.
Leftovers: Additionally, leftovers can build up histamine when stored in the refrigerator. By freezing leftovers in meal portions suitable for you and your family’s needs, you can defrost them to reheat later.
Ripeness: As food ripens, histamine levels may increase. To limit your intake of histamine-rich foods, such as tomatoes and avocados, choose under-ripe fruits and vegetables.
Non-fermented oils: Choose oils without ingredients that may cause sensitivities, such as sesame oil or soy sauce, and opt for non-fermented options like coconut or olive oil. Instead of using processed or dried seasonings, use fresh herbs like basil, thyme, and parsley to increase flavour.
You can significantly decrease your overall exposure to histamines and better manage your symptoms simply by being mindful of how you prepare and store your meals.
When to Try a Low-Histamine Diet

Isabel Smith, M.S., RD, CDN, is a registered dietitian at the Isabel Smith Nutrition in New York City, says, “People who might experiment with a low-histamine diet are ones which experience some classic symptoms [of histamine intolerance], like constant headaches/migraines, sinus issues, hives, skin irritations, digestive issues, irregular menstrual cycle, tissue swelling, anxiety, abdominal cramping, nausea and difficulty regulating body temperature”.
However, a study cited diarrhea, nausea and vomiting, headaches, itchy skin, oral allergy syndrome, red eyes, and swollen eyelids as some of the most typical symptoms of histamine sensitivity. Histamine intolerance often occurs alongside other food sensitivities, like lactose or fructose intolerance.

Final Thoughts
Eating a low-histamine diet doesn’t have to be boring or restrictive. Instead, it can be pretty enjoyable and nutritious. When you focus on fresh ingredients, simple preparation, and whole foods, it is possible to make delicious and easy-to-digest meals.
What truly matters is keeping things fresh and simple, rather than relying on complex recipes. You will find that fresh meats, colorful vegetables, gluten-free grains, and fresh herbs provide a broad spectrum of practical alternatives that benefit your health while also tasting good.
Most importantly, listen to your body. Since each individual’s tolerance for histamines is unique, keep a record of symptoms and reactions in a food journal. With the help of your healthcare professional or dietitian, you can then gradually reintroduce the foods and find a balance that works for you.
