Mushrooms are a versatile and widely consumed ingredient, but they can also cause allergic reactions in some people. Mushroom allergies are relatively uncommon, but they can be severe and even life-threatening in rare cases. The symptoms of a mushroom allergy can range from mild discomfort to anaphylaxis, and they may include hives, stomach pain, respiratory issues, nausea, vomiting, and diarrhea. The duration of a mushroom allergy can vary from a few hours to a few days, and the most effective treatment is to avoid mushrooms altogether. It is important to note that mushroom allergies may be linked to mold allergies, and exposure to mushroom spores through consumption, inhalation, or skin contact can trigger an allergic reaction.

What You'll Learn
Mushroom allergy symptoms
Mushrooms are a versatile and widely-consumed ingredient, enjoyed in various cuisines worldwide. However, for some people, they can trigger adverse reactions, including allergic responses that range from mild to severe.
More severe symptoms can indicate an anaphylactic reaction, a life-threatening allergic response that requires immediate medical attention. These may include difficulty breathing, wheezing, dizziness, rapid heartbeat, severe abdominal pain, a weak pulse, and a sudden drop in blood pressure, which can lead to loss of consciousness.
In addition to the symptoms mentioned above, individuals with a mushroom allergy may also experience swelling of the lips, face, or throat, and nausea.
If you suspect that you have a mushroom allergy, it is important to consult with an allergist for diagnosis and treatment. The skin prick test, or the blood test, are common methods of diagnosing allergies.

Mushroom allergy diagnosis
Another test used to diagnose mushroom allergies is the blood test, which measures the amount of specific antibodies, known as Immunoglobulin E (IgE), in the blood. High levels of IgE indicate an allergic reaction. However, blood test results are typically available after a few days, unlike the immediate results provided by skin prick tests.
Food allergy testing is also employed in mushroom allergy diagnosis. This involves injecting a minute amount of mushroom protein into the skin. If any inflammation or redness is observed, the patient is diagnosed with a mushroom allergy. Doctors must be prepared to treat any adverse reactions that may occur during this test. Once a diagnosis of an allergic reaction is confirmed, an antihistamine should be administered to alleviate the patient's discomfort. If symptoms are severe, steroids or epinephrine may be necessary.
It is worth noting that the overall extent of mushroom allergies is not precisely known. They may be very slight (1%) or as prevalent as pollen and mould allergies (10-30% of an allergic population). Additionally, mushroom allergies may be linked to allergies to other fungus-related foods, such as mycoprotein, fermented foods, and foods contaminated with fungi.

Mushroom allergy treatment
Mushroom allergy symptoms can vary from mild to severe and may even be life-threatening in some cases. Mild symptoms include a rash, itching, hives, sneezing, nasal congestion, and minor digestive issues such as stomach discomfort. In more severe cases, an individual may experience anaphylaxis, a severe allergic reaction that can cause a drop in blood pressure, difficulty breathing, and loss of consciousness.
The choice of treatment for a mushroom allergy typically depends on the severity of the allergy and the patient's overall health condition. Medications are often the first line of treatment. Over-the-counter (OTC) antihistamines can help alleviate mild symptoms such as a runny nose, itching, and sneezing. For severe symptoms, doctors may prescribe corticosteroids to reduce inflammation. In emergency cases, such as anaphylaxis, epinephrine (also known as adrenaline) is administered.
Allergy shots, also known as allergen immunotherapy, involve injecting small doses of the allergen into the body to help build up immunity. Over time, this can reduce the severity of allergic reactions. This treatment method is typically recommended for patients with severe allergies or those who don't respond well to medications.
The most effective way to prevent a mushroom allergy is to avoid exposure to mushrooms. This includes not only avoiding eating mushrooms but also avoiding areas where mushrooms are grown or processed. Since mushrooms are a common ingredient in many dishes, it is important to read food labels carefully and ask about ingredients in restaurants.
Research into mushroom allergies is ongoing, and there is currently no cure for mushroom allergies. However, scientists are investigating various treatment options, including immunotherapy and developing hypoallergenic mushroom varieties.

Mushroom allergy vs intolerance
Mushrooms are a type of fungus that is widely consumed as a nutritious food worldwide. However, some individuals may experience an allergic reaction after consuming mushrooms. The overall extent of mushroom allergies is not known, but it is estimated that it could be as prevalent as pollen and mould allergies, affecting 10-30% of an allergic population.
Mushroom Allergy:
Mushroom allergy occurs when the human body misinterprets the proteins in mushrooms as foreign particles. The body then releases IgE antibodies to combat these proteins, which in turn releases histamines, causing an allergic reaction. Common symptoms of a mushroom allergy include hives, swelling, coughing, wheezing, vomiting, and diarrhoea. In severe cases, a mushroom allergy can lead to anaphylaxis, a life-threatening allergic reaction characterized by a drop in blood pressure, difficulty breathing, and loss of consciousness. The most effective treatment for a mushroom allergy is to avoid mushrooms altogether and consult with an allergist for diagnosis and treatment. Antihistamines can help relieve mild allergy symptoms, but they are not effective in treating anaphylaxis.
Mushroom Intolerance:
While less common, some individuals may also experience an intolerance to mushrooms, which is different from a mushroom allergy. Intolerances are typically related to the digestive system, whereas allergies involve the immune system. Symptoms of a mushroom intolerance may include stomach pain, bloating, and digestive issues. Treatment for a mushroom intolerance typically involves avoiding mushrooms and identifying and treating any underlying conditions that may be contributing to the intolerance. In some cases, home remedies such as aloe vera or garlic may help to ease the symptoms of a mushroom intolerance.

Mushroom allergy research
Mushrooms are widely consumed as a nutritious food worldwide. However, mushrooms are also a common ingredient in many dishes, and some individuals may experience an allergic reaction after consuming them. Mushroom allergy symptoms can range from mild to severe and can even be life-threatening in some cases.
The overall extent of mushroom allergies is not known, but it is estimated to be very slight (1%) in terms of ingestion, but it could be as prevalent as pollen and mould allergies (10-30%) in an allergic population. Mushroom allergy symptoms can appear within minutes to hours after consuming mushrooms. Common symptoms include hives, swelling, coughing, wheezing, vomiting, and diarrhoea. In more severe cases, anaphylaxis can occur, which requires immediate treatment with epinephrine.
Fungus-related foods, such as edible mushrooms, mycoprotein, and fungi-fermented foods, can cause fungus food allergy syndrome (FFAS) by allergic cross-reactivity with airborne fungi. FFAS may involve one or more target organs, with various allergy symptoms ranging from oral allergy syndrome to severe anaphylaxis. Mycoprotein, a protein-rich food obtained from filamentous fungal biomass, is gaining popularity as an alternative to meat. However, complaints have been made about adverse reactions, including urticaria, swelling of the throat, tongue, mouth, or lips, breathing difficulties, and anaphylaxis.
Research into mushroom allergens has been challenging due to the reliance on naturally growing mushrooms, which are frequently contaminated by other allergen sources. Additionally, the choice and recognition of species are difficult. Most known allergenic mushrooms and fungi are universal and grow in Europe and North America. However, the genus Chlorophyllum is only found in North America, while its close relative, the genus Macrolepiota, is common in Europe.
To effectively treat a mushroom allergy, individuals should avoid all types of mushrooms, including shiitake, portobello, white button, and oyster mushrooms. Antihistamines can help relieve mild allergy symptoms, but they are ineffective against anaphylaxis. If an individual suspects a mushroom allergy, they should consult an allergist for diagnosis and treatment.
