1. Understanding Histamine and Its Impact
1.1. What is Histamine?
Histamine is an organic nitrogenous compound involved in local immune responses, regulating physiological function in the gut and acting as a neurotransmitter for the brain, spinal cord, and uterus. In the body, histamine is produced as part of an immune response to allergens. It is stored in mast cells and basophils, and released when the body detects a threat, such as an allergen, causing symptoms like itching, sneezing, and inflammation. Histamine also plays a role in stomach acid production, helping with digestion. Maintaining balanced histamine levels is crucial for overall well-being.
1.2. What is Histamine Intolerance?
Histamine intolerance is a condition characterized by the body’s inability to properly break down histamine, leading to an accumulation of histamine and a range of adverse symptoms. This can occur when there is an imbalance between histamine intake and the body’s capacity to degrade it. Diamine oxidase (DAO) is the primary enzyme responsible for breaking down ingested histamine. When DAO activity is reduced, histamine levels can rise, triggering various symptoms.
1.3. What are the Symptoms of Histamine Intolerance?
Histamine intolerance can manifest through a wide array of symptoms, often mimicking those of allergies or other conditions, making it challenging to diagnose.
Common symptoms include:
- Headaches and migraines
- Skin issues like hives, eczema, and itching
- Digestive problems such as bloating, diarrhea, and abdominal pain
- Respiratory symptoms like nasal congestion, sneezing, and asthma
- Cardiovascular issues, including heart palpitations and irregular heart rate
- Fatigue and anxiety
These symptoms can vary in severity and may be triggered by specific foods or environmental factors. Recognizing these signs is the first step in managing histamine intolerance.

1.4. How is Histamine Intolerance Diagnosed?
Diagnosing histamine intolerance can be complex due to the wide range of symptoms and the lack of a single, definitive test. Doctors often use a combination of methods to reach a diagnosis.
The diagnostic process typically involves:
- Medical History and Symptom Assessment: A thorough review of your symptoms, medical history, and dietary habits.
- Elimination Diet: Removing high-histamine foods from your diet for a period (usually 2-4 weeks) to see if symptoms improve.
- Histamine Challenge Test: Under medical supervision, consuming a controlled amount of histamine to observe if symptoms are triggered.
- DAO Enzyme Level Test: Measuring the levels of diamine oxidase (DAO) in your blood, although this test is not always reliable.
If symptoms improve on a low-histamine diet and are triggered by the histamine challenge, histamine intolerance is likely. Consulting with a healthcare professional or registered dietitian is crucial for accurate diagnosis and management.
2. High-Histamine Foods to Avoid or Limit
2.1. Fermented Foods
Fermented foods are a significant source of histamine because the fermentation process encourages histamine production.

FAQ: Foods High in Histamine
1. What exactly is histamine intolerance?
Histamine intolerance occurs when your body can’t break down histamine properly, leading to a buildup and causing various symptoms like headaches, skin issues, and digestive problems. This imbalance is often due to reduced activity of the diamine oxidase (DAO) enzyme, which is responsible for breaking down histamine.
2. Which foods contain the highest levels of histamine?
Foods with high histamine levels include fermented items like aged cheeses, sauerkraut, and kimchi; alcoholic beverages, especially red wine and beer; processed and smoked meats like salami and ham; certain types of fish, such as mackerel and tuna; and pickled or canned foods.
3. Can cooking methods affect histamine levels in food?
Yes, cooking methods can impact histamine levels. Freshly cooked foods generally have lower histamine levels compared to leftovers or foods that have been stored for extended periods. Histamine levels increase as food ages, so it’s best to consume freshly prepared meals.
4. Are there any fruits and vegetables I should avoid on a low-histamine diet?
Yes, certain fruits and vegetables are known to be higher in histamine or act as histamine liberators. These include citrus fruits like oranges and lemons, strawberries, tomatoes, spinach, and eggplant.
5. What are histamine liberators, and how do they affect me?
Histamine liberators are foods that don’t necessarily contain high levels of histamine themselves but can trigger the release of histamine from mast cells in your body. Common histamine liberators include citrus fruits, chocolate, tomatoes, and certain nuts.
6. How can I tell if I have histamine intolerance?
Symptoms of histamine intolerance can vary but often include headaches, skin rashes, digestive issues, nasal congestion, and fatigue. A doctor may use an elimination diet, histamine challenge test, or DAO enzyme level test to diagnose the condition.
7. Are there any supplements that can help with histamine intolerance?
Yes, DAO (Diamine Oxidase) supplements can help break down histamine in the digestive tract, reducing symptoms. However, it’s essential to consult with a healthcare provider before starting any new supplements.
8. What is the best way to store food to minimize histamine buildup?
To minimize histamine buildup, it’s best to freeze fresh meats and fish immediately if you can’t cook them right away, refrigerate cooked food promptly, and use airtight containers for storage. Avoid leaving food at room temperature for extended periods.
9. Can I still eat out if I have histamine intolerance?
Eating out with histamine intolerance can be challenging, but it’s possible with careful planning. Choose restaurants that prepare food fresh, ask about ingredients and preparation methods, and avoid dishes with common high-histamine ingredients.
10. Where can I find more information and support for managing histamine intolerance?
