Histamine is a chemical released by the body's immune system in response to allergens. While histamine is typically associated with allergy symptoms, it also plays a role in regulating sleep-wake cycles and cognitive function. Histamine intolerance, which affects about 1% of the population, occurs when the body cannot break down histamine properly, leading to a build-up that may cause various symptoms. Certain foods are known to be high in histamine or contain histamine-like substances, including some fruits and fermented foods. Mushrooms have been a topic of discussion in the context of histamine intolerance, with some sources classifying them as medium histamine foods and others considering them safe for a low-histamine diet. While most edible mushrooms are generally low in histamine, they contain histamine-like amines and may trigger symptoms in individuals with histamine intolerance.

What You'll Learn
Histamine intolerance
Histamine is a chemical released by the body's immune system in response to potential allergens. It is also known for contributing to allergy symptoms, such as coughing, wheezing, and watery eyes. Histamine has other functions, including regulating the sleep-wake cycle and cognitive function.
The symptoms of histamine intolerance are diverse and non-specific, often mimicking those of other conditions, which can make diagnosis challenging. Gastrointestinal issues are the most common symptoms, including bloating, abdominal discomfort, gas, diarrhoea, and constipation. Other symptoms include headaches, nasal congestion, fatigue, and other related issues.
There is no specific direct test to diagnose histamine intolerance. Doctors may suggest an elimination diet, where high-histamine foods are avoided for a few weeks, and then slowly reintroduced one at a time to identify any triggers. Incorporating low-histamine foods into the diet can help reduce symptoms, and DAO supplements may also be beneficial, although more research is needed to confirm their effectiveness.
While nearly all foods contain some histamine, certain foods are recommended to be limited or avoided on a low-histamine diet, including some fruits, mushrooms, soybeans, and processed meats.

Histamine in mushrooms
Histamine is a chemical released by the human immune system in response to potential allergens. It is known for contributing to allergy symptoms, such as coughing, wheezing, and watery eyes. However, histamine also has other functions, such as regulating the sleep-wake cycle and cognitive function. While histamine intolerance is not considered a food allergy, it affects approximately 1% of the population and causes the body to be unable to break down histamine correctly, leading to a buildup. This can result in bothersome symptoms, including allergy-like reactions, headaches, nasal congestion, fatigue, and gastrointestinal disturbances.
Mushrooms are generally considered a low-histamine food and may be suitable for individuals following a low-histamine diet. Common edible mushrooms include shiitake, reishi, cordyceps, cremini, white, button, and portobello mushrooms. However, it is important to note that histamine levels can vary among different types of mushrooms. Some studies suggest that while mushrooms are low in histamine, they contain histamine-like amines like putrescine, which could increase the adverse effects of histamine and trigger symptoms in individuals with histamine intolerance.
The impact of mushrooms on individuals with histamine intolerance can vary significantly. While some people with histamine intolerance may experience symptoms after consuming mushrooms, others may tolerate them well. It is recommended that individuals with histamine intolerance work closely with a healthcare provider to determine their tolerance level and the appropriate amount and type of mushrooms to include in their diet. Keeping a list of high-histamine foods and slowly reintroducing suspected trigger foods can help identify specific triggers.
Additionally, the processing and preparation of mushrooms can affect their histamine content. A study analyzing 53 processed and unprocessed mushroom samples found that spermidine and putrescine, rather than histamine, were the most common amides in mushrooms. However, dried Polish forest mushrooms were identified as having high amounts of histamine in eight samples. Therefore, it is important to consider not only the type of mushroom but also its processing and preparation when assessing its histamine content.

Histamine-like substances
Histamine is a chemical released by the immune system in response to potential allergens. Histamine intolerance occurs when the body is unable to break down histamine correctly, causing a buildup that may lead to allergy-like symptoms. While histamine levels in mushrooms vary, they are generally considered low-histamine foods and may be suitable for a low-histamine diet. However, mushrooms contain histamine-like amines, such as putrescine and spermidine, which can potentially trigger symptoms in individuals with histamine intolerance.
Putrescine, a histamine-like amine, is found in significant amounts in mushrooms. Putrescine belongs to a class of compounds known as polyamines, which are involved in various biological processes, including cell growth and differentiation. While putrescine itself may not cause direct adverse effects, it can interact with histamine receptors and influence histamine metabolism. In individuals with histamine intolerance, the presence of putrescine in mushrooms could exacerbate the effects of histamine, leading to symptoms such as headaches, nasal congestion, fatigue, and gastrointestinal issues.
Spermidine is another histamine-like substance found in mushrooms. Spermidine is also a polyamine compound, structurally similar to putrescine, and it plays a role in cellular metabolism and stability. Similar to putrescine, spermidine can affect histamine metabolism and breakdown. For individuals with histamine intolerance, the presence of spermidine in mushrooms may contribute to an imbalance in histamine levels, potentially triggering symptoms associated with histamine intolerance.
Additionally, some mushrooms contain other bioactive compounds, such as beta-glucans, which are responsible for exerting powerful functions in the body. While beta-glucans are known for their beneficial effects on immune response and intestinal health, they can also interact with the immune system in ways that are not fully understood. In some cases, beta-glucans may influence histamine release or sensitivity, potentially impacting individuals with histamine intolerance.
It is important to note that the effects of histamine-like substances in mushrooms can vary depending on individual sensitivity and the specific type of mushroom. While some people may experience symptoms of histamine intolerance after consuming mushrooms, others may tolerate them well. Therefore, it is advisable for individuals with histamine intolerance to work closely with healthcare professionals to determine their tolerance levels and include mushrooms in their diet accordingly.

Histamine testing
Histamine is a chemical released by the immune system in response to potential allergens. It is typically known for causing allergy and anaphylactic symptoms, which can become severe or life-threatening. Histamine intolerance, also known as enteral histaminosis or sensitivity to dietary histamine, is a disorder associated with an impaired ability to metabolize ingested histamine. It is characterized by allergy-like symptoms such as coughing, wheezing, and watery eyes. It can also cause headaches, nasal congestion, fatigue, and gastrointestinal disturbances.
- Skin Prick Test: This involves pricking the skin with tiny drops of allergens to observe any reactions.
- Blood Testing: Blood tests can reveal high histamine levels, low levels of DAO (diamine oxidase, the protein responsible for breaking down histamine), or other irregularities.
- Test Kits: Advanced test kits, such as ELISA, can accurately detect and quantify histamine levels in food products, ensuring consumer safety and regulatory compliance.
- Dietary Approach: Individuals can track potential symptoms after consuming mushrooms or other amine-containing foods to identify triggers and manage histamine intolerance.
It is important to note that specific foods to limit or avoid on a low-histamine diet vary from person to person based on their sensitivity. While mushrooms are generally considered low-histamine foods, some studies suggest that their high putrescine content (another amine) may increase the adverse effects of histamine, triggering symptoms in individuals with histamine intolerance. Therefore, individuals with histamine intolerance should work closely with healthcare providers to determine the appropriate amount and type of mushrooms in their diet.

Histamine and allergies
Histamine is a chemical released by the immune system in response to potential allergens. It is known for causing allergy and anaphylactic symptoms, which can become severe or life-threatening. Seasonal allergies are often the cause of histamine production in the body, but foods can also contain this chemical. Histamine intolerance occurs when the body cannot break down histamine properly, leading to a buildup that may cause bothersome symptoms. While nearly all foods contain some histamine, certain foods are recommended to be limited or avoided on a low-histamine diet.
Mushrooms are generally considered low-histamine foods and may be included in a low-histamine diet. Common edible mushrooms include shiitake, reishi, cordyceps, cremini, white, button, and portobello mushrooms. However, studies suggest that a high putrescine content in mushrooms, another type of amine, could increase the adverse effects of histamine. This may explain why some people associate mushroom consumption with histamine intolerance symptoms and choose to avoid them. Additionally, mushrooms may contain histamine-like substances that can trigger symptoms in individuals with histamine intolerance.
Individuals with histamine intolerance may exhibit symptoms such as headaches, nasal congestion, fatigue, and gastrointestinal disturbances after consuming mushrooms. The response to mushroom consumption can vary significantly among those with histamine intolerance. It is recommended that these individuals work closely with a healthcare provider to determine the appropriate amount and type of mushrooms to include in their meal plan. Keeping a list of high-histamine foods can be a helpful strategy for identifying and avoiding them.
To determine if a particular food triggers histamine intolerance, a gradual reintroduction approach can be taken. After avoiding high-histamine foods for a few weeks, specific foods can be slowly added back into the diet one at a time. If symptoms reappear, the recently added food may be identified as a trigger. Allergy testing, such as skin prick tests or blood tests, can also help identify the cause of symptoms.
