Mushrooms are tasty and have been used in culinary fields across global kitchens for their unique flavor and various nutritional benefits. However, consuming or inhaling the spores of mushrooms can cause an allergic reaction (mushroom allergy) in some people (1). In this article, we discuss in detail several options available for treating mushroom allergy symptoms. Read on to know more!

A mushroom allergy can be either due to eating mushrooms or inhaling their spores (2). They are usually classified into three types – intolerance, allergic reactions, and poisoning.

Intolerance to mushrooms creates a slight feeling of illness, while an allergic reaction causes serious immediate symptoms. Mushroom poisoning is caused due to the consumption of poisonous mushrooms and has more severe symptoms.

A study found that the pollen spores of mushrooms peak usually in August and September (3).

Causes Of Mushroom Allergy

Mushroom allergy occurs when the human body misinterprets the proteins in mushrooms as foreign particles. As a response, the human body releases IgE antibodies to combat the proteins (4). This, in turn, releases histamines, which cause allergies.

The symptoms associated with mushroom allergies include:

  • Wheezing
  • Runny nose and/or watery eyes due to an inflamed upper respiratory tract
  • Skin rashes or hives
  • Swelling of the lips, mouth, and/or throat
  • Diarrhea
  • Vomiting
  • Nausea
  • Bloating or stomach cramping

More severe symptoms associated with mushroom allergy include:

  • A drop in blood pressure
  • Shortness of breath
  • Fainting

How To Diagnose Mushroom Allergy

A skin prick test is considered to be an accurate diagnostic method for food allergy (5). In this test, a very small amount of mushroom protein is injected into the skin. The patient is considered to be allergic to mushrooms if any inflammation or redness is observed in the injected area.

Allergy testing measures IgE antibodies to determine how serious of an allergy someone possesses.

Doctors should be well prepared to tackle any adverse reactions that may occur during the test.

How Is Mushroom Allergy Treated?

Treatment of mushroom allergy involves the administration of an antihistamine. Antihistamines are generally used in the management of allergic conditions (6). These medicines can be administered orally or through a nasal spray.

However, immediate medical attention is required when the symptoms are serious. For example, in the event of an anaphylactic reaction, an epinephrine shot should be administered immediately. This may relax the respiratory tract (7). A doctor should be contacted immediately as the symptoms can be fatal.

In addition to an effective treatment, there are a few remedies that may help alleviate mushroom allergy symptoms. They are listed below.

Remedies For Mushroom Allergy

Aloe Vera

  • Anecdotal evidence suggests that the soothing properties of aloe vera may help ease mushroom allergies.
  • It has natural anti-inflammatory and anti-itch properties.
  • Apply pure aloe vera gel on the skin to reduce redness and itching.
  • When taken as a juice or supplement, it may help ease digestive discomfort associated with mushroom allergies.

Garlic

  • Although garlic is not a direct treatment, it boosts the body’s immune system.
  • This may potentially reduce the severity of mushroom allergy reactions.
  • Including garlic in your diet can enhance your body’s ability to handle allergens.
  • Prior to trying these remedies, consult a healthcare professional to ensure safety and suitability for your specific situation.

The necessary precautions must be taken to avoid the recurrence of allergy symptoms once they are managed and brought under control. Here are a few tips to prevent mushroom allergies:

  • Avoid mushrooms and other mold products like yeast.
  • Keep anti-allergic medications (like nasal steroids) handy.
  • Consume packaged foods (sour creams, dry fruits, beer, cheese, etc.) with caution as they may trigger allergic reactions in some individuals.

Allergy to mushrooms can lead to an inflammation of the upper respiratory tract, hives, rashes, swollen lips, mouth, or throat, nausea, vomiting, nasal congestion, digestive problems, and even serious symptoms like fainting, low blood pressure, or dizziness. The allergic reaction happens due to the consumption of mushrooms or the inhalation of the spores as the body misidentifies the proteins in them as foreign particles. The most common way to treat a mushroom allergy is to use oral or nasal antihistamines. As allergic reactions to mushrooms can be extremely severe and result in anaphylaxis (a life-threatening allergic reaction), it is important to identify them and avoid exposing yourself to mushrooms or their spores.

Frequently Asked Questions

What are the differences between molds and mushrooms?

Molds are a group of fungi called hyphomycetes. They are characterized by filamentous hyphae. They produce airborne conidia or spores. Mushrooms are also a group of fungi that are characterized by a fruiting body. While all mushrooms are fungi, only a few of them are edible. Some mushrooms may prove to be hazardous to health.

How common is a mushroom allergy?

There is a lack of data regarding the prevalence of mushroom allergies. However, research suggests that allergy to mushroom consumption may be present in around 1% of the allergic population, and allergy to spores/mold is prevalent amongst 10-30% of an allergic population (3).

Can I eat curd with mushrooms?

According to proponents of Ayurveda, sour foods like mushrooms should not be consumed with dairy products such as curd. However, curd and mushrooms are often combined in various recipes and do not seem to have any adverse effects.

Key Takeaways

  • A few signs of mushroom allergy are skin rashes, itching, nausea, sneezing, abdominal pain, and difficulty breathing.
  • Allergic reactions can be triggered by consuming any part of the mushroom or inhaling its spores.
  • Some necessary precautions for mushroom allergies include avoiding mushroom exposure, carrying anti-allergic medications, and consuming packaged foods with extreme caution.
  • A mushroom allergy can be diagnosed through a skin prick test; it is important to get a proper diagnosis to avoid any allergic reactions.
