Mushrooms are a popular food enjoyed for their rich flavour and nutritional benefits. They come in many varieties, from common button mushrooms to exotic varieties like shiitake and oyster mushrooms. However, while mushrooms offer many health benefits, they can also cause side effects.

Some mushrooms are toxic, and even edible ones can lead to digestive problems or allergic reactions in some people. Read on to discover the possible side effects of mushrooms.

What are the side effects of mushrooms?

The following are some of the most common mushroom side effects:

  1. Digestive issues

  • Some varieties of mushrooms are difficult to digest and can cause stomach pain, bloating, nausea, or diarrhoea.
  • Wild mushrooms may contain harmful bacteria that upset the stomach.
  1. Allergic reactions

  • Some people may be allergic to mushrooms, causing symptoms such as rashes, itching, or swelling.
  • In severe cases, the allergic reaction may cause difficulty in breathing that requires immediate medical attention.
  1. Poisoning from toxic mushrooms

  • Certain wild mushrooms, such as the death cap, are poisonous and may lead to severe illness or even death.
  • Symptoms of mushroom poisoning include vomiting, dizziness, and confusion.
  • It is important to be cautious when picking wild mushrooms, as some edible varieties closely resemble toxic ones.
  1. Drug interactions

  • Some medicinal mushrooms, like reishi or lion’s mane, may interact with medications.
  • They can affect blood sugar levels, blood pressure, or the immune system.
  1. Liver and kidney Issues

  • Certain mushrooms, when eaten in large amounts, may put stress on the liver and kidneys.
  • Some wild mushrooms have toxins that can cause long-term damage to these organs.
  1. Contamination with pesticides or heavy metals

  • Mushrooms grown in polluted environments may absorb heavy metals and pesticides due to their unique ability to take in substances from the soil. This makes them more prone to accumulating contaminants like pesticides and metals.
  • Consuming contaminated mushrooms over time may lead to health problems.

Conclusion

Mushrooms can be a nutritious and flavourful addition to many meals, but they also come with risks. Some people may experience digestive problems, allergic reactions, or even poisoning from toxic varieties. Additionally, medicinal mushrooms may interact with medications.

To ensure safety, always buy mushrooms from trusted sources, cook them properly, and avoid eating wild mushrooms unless identified by an expert. If you experience any side effects after eating mushrooms, seek medical advice. Appropriate health insurance plans can cover the cost of health checkups, consultations, and treatment if necessary.
