Mushrooms are fleshy fruit bodies of several macrofungi species. Edible mushrooms are consumed for their nutritional and culinary value, and some are even used in folk medicine. However, some mushrooms are poisonous and can cause severe health issues or even death. The identification of edible mushrooms is crucial to ensure safety, as some poisonous mushrooms closely resemble non-toxic varieties. The world's most lethal mushroom, the death cap, is responsible for 90% of fatalities from consuming toxic fungi.
| Characteristics | Values |
|---|---|
| Definition | Mushrooms are the fleshy fruit bodies of numerous species of macrofungi (fungi that bear fruiting structures large enough to be seen with the naked eye). |
| Scientific Name | The scientific name for mushrooms is Agaricus bisporus. |
| Common Varieties | Common white, button, cultivated, and champignon mushrooms are all names for the youngest form of Agaricus bisporus. Its semi-mature form is known as cremini, baby-bella, Swiss brown, Roman brown, Italian brown, or chestnut mushroom. Its fully mature form is known as portobello. Other common varieties include shiitake, oyster, morel, king bolete, giant puffball, yellow chanterelle, tube chanterelle, and panther cap mushrooms. |
| Edibility | Edible mushrooms are defined by the absence of poisonous effects on humans and desirable taste and aroma. Poisoning by wild mushrooms is common and may be fatal or cause mild gastrointestinal disturbance or slight allergic reactions. |
| Nutritional Value | Mushrooms are a good source of protein, vitamin D, and umami flavor. |

Edible mushrooms are free of cholesterol and contain essential amino acids and vitamins
Mushrooms are a type of fungus that has been consumed and used in traditional medicine for thousands of years. There are over 2,000 edible varieties of mushrooms, including the prized truffle, matsutake, morel, and chanterelle. Edible mushrooms are cultivated or foraged and are consumed for their nutritional and culinary value.
Edible mushrooms are free of cholesterol and are an excellent source of essential amino acids and vitamins. They are low in calories and fat and contain various vitamins, minerals, antioxidants, and fiber. Specifically, mushrooms contain vitamin C, folate, and several B vitamins, including thiamine, riboflavin, B6, and B12. They are also the only vegan, non-fortified dietary source of vitamin D, which helps the body absorb calcium to maintain and build strong bones. Vitamin D can be obtained by exposing certain varieties of mushrooms, such as white button, portabella, and cremini, to UV light or sunlight.
Mushrooms are a rich source of ergothioneine, an amino acid and antioxidant that prevents or slows cellular damage. They also contain glutamate, another amino acid that gives mushrooms their savory, umami flavor. Additionally, mushrooms are high in polysaccharides, which are believed to have cancer-fighting properties and promote the growth of healthy gut bacteria.
Some edible mushrooms, such as shiitake, have been found to help lower cholesterol levels. They contain compounds that inhibit cholesterol production, block absorption, and reduce overall cholesterol levels in the blood. Incorporating mushrooms into one's diet can also lower the risk of developing mild cognitive impairment (MCI) and other brain health issues.

Poisonous mushrooms can cause mild gastrointestinal disturbance, allergic reactions, or even death
Poisonous mushrooms can cause a range of adverse reactions, from mild gastrointestinal disturbances to severe toxicity, allergic reactions, and even death. It is important to note that there is no reliable home test to distinguish between edible and poisonous mushrooms, and proper identification by a mushroom expert is essential before consumption.
Mild gastrointestinal disturbances are a common symptom of mushroom poisoning, often occurring within 20 minutes to 4 hours of ingestion. Symptoms may include nausea, vomiting, cramps, and diarrhea, which typically resolve after the irritant is expelled from the body. However, severe cases may require hospitalization and supportive treatment to replace lost fluids and electrolytes.
Poisonous mushrooms can also cause allergic reactions in certain individuals. Mushroom allergies occur when the immune system fails to recognize the proteins in the mushroom as safe and attacks them with immunoglobulin E antibodies, triggering the release of histamine. This can lead to inflammation and swelling of the intestines, resulting in gastrointestinal symptoms such as abdominal pain, nausea, vomiting, and diarrhea. Allergic reactions to mushrooms can be serious and require medical evaluation by a doctor.
In addition to gastrointestinal issues and allergic reactions, poisonous mushrooms can also cause severe toxicity and even death. Amatoxins, found in mushrooms like Amanita phalloides (the death cap), can cause serious liver and kidney damage, with symptoms appearing 6 to 24 hours after ingestion. Orellanine, found in certain mushroom species, has a slower onset of symptoms (36 hours to 3 weeks) but can also lead to kidney failure and death.
It is crucial to seek immediate medical attention if you suspect mushroom poisoning or observe symptoms such as gastrointestinal distress, impaired kidney function, excessive salivation, sweating, severe vomiting, diarrhea, visual disturbances, irregular pulse, difficulty breathing, or anaphylaxis. Proper identification of mushrooms by experts and awareness of their potential toxic effects are vital to prevent adverse health consequences.

Mushrooms are a good food option for vegetarians and vegans due to their high protein and vitamin D content
The vitamin D content in mushrooms varies depending on their exposure to UV light. Wild mushrooms like chanterelles and morels, which are naturally exposed to sunlight, can contain up to 1200 IU of vitamin D per 3.5-ounce serving. On the other hand, mushrooms grown in dark conditions, such as white button, shiitake, and oyster mushrooms, contain less than 40 IU. However, even these mushrooms can be a good source of vitamin D if exposed to UV light during production.
In addition to vitamin D, mushrooms are also a good source of protein, vitamins, minerals, and antioxidants. They contain B vitamins, including thiamine, riboflavin, B6, and B12, which are important for energy production and brain health. Mushrooms also provide potassium, vitamin C, and fiber, which contribute to cardiovascular health. The potassium in mushrooms helps regulate blood pressure, reducing the risk of hypertension and cardiovascular disease.
When it comes to cooking mushrooms, sautéing or simmering them over low heat is ideal for preserving their nutrients. Mushrooms have an umami flavor, making them a great replacement for meat in recipes. They can be added to salads, omelets, stir-fries, pasta sauces, and soups, providing both nutritional and culinary benefits.
It is important to note that not all mushrooms are edible, and consuming wild mushrooms without proper knowledge can be dangerous. Poisoning from wild mushrooms is common and can have severe consequences. Therefore, it is crucial to accurately identify edible mushrooms and exercise caution when foraging or consuming wild mushrooms.

Mushrooms can be cultivated or found in the wild
If you're interested in growing your own mushrooms, there are many online communities that can provide guidance and answer questions, such as r/unclebens, r/Shroomery, r/Witchcraft, and the North American Mycological Association (NAMA). These communities can offer advice on cultivation techniques, identification, and more.
Foraging for wild mushrooms can be dangerous, and it's crucial to have the help of an experienced technician or picker. Wild mushrooms can be found in large cities next to shade trees, suburban lawns, and remote woods. The best season to look for them is in the fall, preferably a few days after a large rainfall. Many non-poisonous mushroom varieties are easy to identify, such as Morel, Chanterelle, Oyster, Puffballs, and Coral Fungus. However, it's important to assume that other varieties are poisonous and only consume the types you've confirmed are edible.
Whether you're cultivating mushrooms or foraging for them in the wild, it's important to have the necessary knowledge and expertise to ensure safety and sustainability.

Some mushrooms are used for medicinal purposes
Mushrooms are a fungus that has been used in folk medicine for thousands of years. They are a good source of ergothioneine, an amino acid and antioxidant that prevents or slows cellular damage.
Chaga or Inonotus obliquus, for example, is a highly prized woody canker or conk that grows in the colder regions of the Northern Hemisphere on birch trees. It was first used in Russia around the 16th century as a tea to improve stomach health. Chaga contains high amounts of melanin, which is beneficial for the skin. Many indigenous people continue to use Chaga for its health-supportive properties.
Shiitake, oyster, maitake, and king oyster mushrooms have been found to have higher amounts of ergothioneine. However, researchers have found that incorporating any variety of mushrooms into your daily diet will lower your risk of cancer. Mushrooms are also naturally low in sodium, which helps to keep blood pressure low. A study from the Culinary Institute of America and UC Davis shows that swapping half of the meat for mushrooms in a traditional ground beef recipe can maintain flavor while reducing sodium intake by 25%.
In addition, shiitake mushrooms help to keep cholesterol levels low. They contain compounds that inhibit the production of cholesterol, block cholesterol from being absorbed, and lower overall cholesterol levels in the blood. A study in Singapore found that participants who ate more than two cups of mushrooms (including golden, oyster, shiitake, and white button mushrooms) a week had a 50% lower risk of developing mild cognitive impairment (MCI), which is often a precursor to Alzheimer's disease.
While the medicinal properties of mushrooms are due to the numerous and diverse secondary compounds and metabolites, few studies have been conducted within the framework of clinical trials. Although a medicinal mushroom has been widely used in Taiwan for the treatment of various cancers, a trial provided no evidence of its efficacy in improving the outcome of patients with advanced cancer.
