Understanding and dietary management of histamine intolerance

Histamine intolerance affects many people and can lead to significant impairments in quality of life. Histamine is a biogenic amine that is found in many foods and performs important functions in the body. It regulates blood pressure, supports the immune system and controls the sleep-wake cycle. However, some people cannot break down histamine properly, which leads to various symptoms. In this article, we explain in detail the causes, symptoms and management of histamine intolerance.

What is histamine?

Histamine as a biogenic amine

Histamine is a versatile messenger substance that plays a central role in the human body. It is formed from the amino acid histidine and is present in many foods. Histamine has numerous functions in the body. It is involved in regulating blood pressure, supporting the immune system and controlling the sleep-wake cycle. Histamine also plays a role in appetite control and the inflammatory response. For example, when we have a mosquito bite, histamine causes the itchy hives.

Occurrence in food

Histamine is formed in protein-rich foods through the action of fungi and bacteria. Typical examples are aged cheese, sauerkraut and sausage. Histamine is also formed when food spoils, which means that the level of histamine in foods can vary. Storage time, maturation and processing affect histamine levels. It is therefore difficult to determine the exact histamine content of foods and to generally classify them as “tolerable” or “intolerable”. Nevertheless, there are foods that often have a high histamine content and trigger symptoms in many sufferers. These include alcoholic beverages such as wine and champagne, cheese, fish, tomato products, salami, vinegar and pickled foods, buttermilk, yogurt and mushrooms. There are also histamine liberators, which do not contain much histamine themselves but promote the release of histamine in the body. These foods include cocoa products, nuts, mussels, squid and some types of fruit.

Causes of histamine intolerance

Enzymatic basics

The main cause of histamine intolerance is the reduced activity of the enzyme diamine oxidase (DAO). This enzyme is responsible for the breakdown of histamine in the body. If DAO does not function adequately, the body cannot effectively break down the ingested histamine. This leads to an accumulation of histamine in the blood, which can cause various symptoms.

Genetic and acquired factors

Histamine intolerance can be both genetic and acquired over the course of life. Genetic predispositions can cause a person to have reduced DAO activity from birth. Various studies have shown that certain genetic variations, called single nucleotide polymorphisms, are associated with a deficiency in DAO. In addition, certain medications such as chemotherapy drugs and alcohol can impair the activity of the DAO enzyme. Intestinal diseases such as short bowel syndrome and irritable bowel syndrome can also reduce the functionality and amount of the DAO enzyme. Ingestion of high concentrations of other biogenic amines can also promote temporary histamine intolerance, as the DAO enzymes are busy breaking down these amines.

Symptoms of histamine intolerance

Skin reactions

Histamine intolerance can cause various skin reactions. The most common symptoms include itching, redness and urticaria. These symptoms often appear after eating foods rich in histamine and can be very unpleasant. We should pay attention to which foods trigger these reactions in order to avoid them in the future.

Gastrointestinal complaints

Gastrointestinal complaints are also common symptoms of histamine intolerance. Bloating, abdominal pain, nausea and diarrhea can occur after eating foods rich in histamine. These symptoms can significantly affect the quality of life and lead to a feeling of malaise. A low-histamine diet can help alleviate these complaints.

Respiratory symptoms

Respiratory symptoms are another sign of histamine intolerance. Runny nose, nasal congestion and shortness of breath may occur. These symptoms are often similar to allergic reactions and can be easily confused. It is important to recognize these symptoms and take appropriate action.

Other symptoms

In addition to the skin and respiratory symptoms, other symptoms can also occur. Headaches and heart palpitations are common complaints of histamine intolerance. These symptoms can be very stressful and reduce the quality of life. We can reduce these symptoms by eating a low-histamine diet and avoiding histamine-rich foods.

Diagnosis of histamine intolerance

Food diary

A food diary is a helpful tool for diagnosing histamine intolerance. In a food diary, we write down all the foods we eat and the symptoms we experience. By documenting this, we can identify patterns and determine the relationship between certain foods and the symptoms. A food diary can also help us create an individual low-histamine diet. We should keep the food diary regularly and document all the details precisely.

Medical tests

Various medical tests can be carried out to diagnose histamine intolerance. Measuring the DAO level in the blood is a possible diagnostic aid. In those affected, the concentration of the DAO enzyme is often reduced. However, it is important to note that the concentration of the DAO enzyme alone does not allow a clear conclusion to be drawn about the severity of the disease. A comprehensive medical consultation is necessary in order to interpret the test results sensibly and to rule out other allergies. The diagnosis of histamine intolerance should always be made by a specialist.

Dietary management of histamine intolerance

Avoid foods rich in histamine

Those affected should be aware of which foods have a high histamine content. Aged cheese, such as Parmesan or Roquefort, often contains high amounts of histamine. Canned fish, smoked fish and sausages such as salami and ham are also rich in histamine. Tomato products such as ketchup and tomato sauce as well as alcoholic beverages such as wine and champagne are also problematic. These foods can trigger symptoms such as headaches, skin rashes or digestive problems. It is therefore important to eliminate these foods from your daily diet or to reduce them significantly.

Low histamine diet

A low-histamine diet can help alleviate the symptoms of histamine intolerance. Freshly cooked meat and poultry are usually low in histamine and well tolerated. Fresh or frozen fish that has not been stored for long can also be consumed without problems. Plant-based milks such as coconut milk and almond milk are a good alternative to cow’s milk products, which can contain histamine. Fresh vegetables such as onions, sweet potatoes, broccoli and beetroot are also recommended. Fruits such as blueberries, apples, mangos and peaches are usually well tolerated and can be consumed without concern. These foods provide important nutrients and help to minimize histamine intake.

Foods that release histamine

Some foods release histamine into the body even if they do not contain much histamine themselves. These so-called histamine liberators include cocoa products, nuts, seafood such as mussels and squid, and certain fruits such as strawberries and pineapples. These foods can worsen the symptoms of histamine intolerance because they promote the release of histamine in the body. It is therefore advisable to avoid these foods as well or only consume them in small quantities.

Additional measures

Dietary supplements

In addition to a low-histamine diet, dietary supplements can provide valuable support. Vitamin C is known to support the histamine breakdown processes in the body. B vitamins such as B6 and B12 and minerals such as magnesium and zinc can also be helpful. Quercetin, a plant-based active ingredient, has anti-inflammatory properties and can inhibit the release of histamine. DAO dietary supplements are also available on the market. These contain the enzyme diamine oxidase, which helps break down histamine. However, the effectiveness of these preparations has not yet been sufficiently proven by studies. Therefore, dietary supplements should always be taken in consultation with a doctor.

Medication

Antihistamines can help to relieve the symptoms of histamine intolerance in the short term. These medications block the effects of histamine and can thus reduce symptoms such as itching, headaches or gastrointestinal problems. There are also topical creams that can be used for skin reactions. However, these should only be used under medical supervision. In severe cases, oral steroids may be necessary to control the inflammatory reactions in the body. Homeopathic and herbal remedies can also be supportive, but should also be discussed with a doctor.

Supportive measures

Apps to monitor the histamine content in food and track symptoms can be very useful. They help you keep track and adjust your diet accordingly. Stress management techniques such as yoga, meditation and breathing exercises can also be helpful. Stress can worsen the symptoms of histamine intolerance, so it is important to incorporate regular relaxation techniques into your daily routine. Support from family and friends is also important. They can help you stick to the dietary change and provide moral support.

Practical tips and everyday coping

Dietary changes

Dietary changes can be challenging, especially at first. It’s important to be well prepared and have a plan. Start by removing high-histamine foods from your pantry and replacing them with low-histamine alternatives. Plan your meals in advance and make shopping lists to ensure you always have the right foods on hand. Reading food labels can also help avoid hidden histamine. It can also be helpful to talk to other sufferers and share experiences and recipes.

family and friends

Support from family and friends is crucial to the success of the dietary change. Explain to them what histamine intolerance is and which foods to avoid. Shopping and cooking together can help to integrate the new diet into everyday life. It is also important to be patient and understanding, especially in social situations such as family gatherings or going to restaurants. Over time, the new diet will become routine and support from loved ones can make this process easier.

Sports and exercise

Regular physical activity can alleviate the symptoms of histamine intolerance and improve general well-being. Exercise helps reduce stress and boost metabolism. Suitable sports include yoga, Pilates, swimming and walks in the fresh air. These activities are gentle and can be easily integrated into everyday life. Even small exercise sessions such as stretching exercises or short walks during the working day can be helpful. It is important to find a sport that is fun and can be practiced regularly.

Quality of life despite histamine intolerance

Positive perspectives and long-term strategies

Conscious food choices and effective stress management can significantly improve the quality of life despite histamine intolerance. It is important to maintain a positive attitude and focus on the benefits of the new diet. Avoiding histamine-rich foods can lead to greater well-being and fewer complaints. Over time, the low-histamine diet becomes a habit and symptoms become more controllable. We discuss the latest research and developments aimed at improving the diagnosis and treatment of histamine intolerance. New studies and innovative approaches offer hope for even more effective management strategies. Through continuous learning and adaptation, we can lead a fulfilling and healthy life in the long term.

Through the combination of a well-planned diet, supportive measures and a positive attitude, we can successfully overcome the challenges of histamine intolerance. Together we can create a future worth living despite this disease.
