Mushrooms are a fungus with a variety of culinary and medicinal uses. They are a rich source of potassium, selenium, vitamin D, vitamin B6, and ergothioneine, an amino acid and antioxidant that prevents or slows cellular damage. They are also a prebiotic, stimulating the growth of healthy bacteria in the gut. Some mushrooms, known as magic mushrooms, contain the hallucinogenic substances psilocybin and psilocin. These mushrooms are illegal in most of the US and can be extremely dangerous, as they closely resemble certain types of poisonous mushrooms.

Nutritional benefits: vitamins, minerals, and sodium content
Mushrooms are a rich source of potassium, which helps to reduce the negative impact of sodium on the body. Potassium also helps to lower blood pressure by lessening tension in blood vessels. Mushrooms themselves are naturally low in sodium, with just five milligrams of sodium in a cup of white button mushrooms. Therefore, adding mushrooms to recipes can help reduce sodium intake, which is beneficial for maintaining low blood pressure.
Mushrooms are also a great source of selenium, vitamin D, and vitamin B6. Selenium helps to prevent cell damage, while vitamin D aids in cell growth, and vitamin B6 helps our bodies form red blood cells. All these nutrients contribute to a healthy immune system.
Additionally, mushrooms contain high amounts of ergothioneine, an amino acid and antioxidant that prevents or slows down cellular damage. Research has shown that eating just 18 grams of mushrooms a day may lower your risk of cancer by up to 45%.
Mushrooms are also a good source of prebiotics, which stimulate the growth of healthy bacteria in the gut. Mushroom polysaccharides, their most abundant carbohydrate, pass through the stomach unchanged and reach the colon to encourage bacterial growth.
When it comes to weight loss, mushrooms can play a role in combination with exercise and other lifestyle changes. They make an excellent substitute for red meat, helping to minimize calories, fat, and cholesterol.

Health benefits: cancer prevention, cholesterol, and blood pressure
Mushrooms are a nutrient-dense food with a variety of health benefits. They are rich in potassium, vitamin C, fibre, protein, selenium, vitamin D, vitamin B6, and antioxidants. These nutrients can help prevent and manage various health conditions, including cancer, high cholesterol, and high blood pressure.
Cancer Prevention
Mushrooms have been shown to have cancer-fighting properties due to their high content of antioxidants and other nutrients. Studies suggest that consuming 1 to 2 cups of mushrooms weekly may reduce the risk of cancer by up to 45%. Certain varieties, such as shiitake, oyster, and maitake, contain higher amounts of ergothioneine, a powerful antioxidant that may help reduce cancer risk. Additionally, mushrooms are a source of beta-glucans, a type of fibre that has been linked to lower cholesterol levels and may also contribute to cancer prevention.
Cholesterol
Mushrooms are an effective food for lowering cholesterol levels. They contain compounds that inhibit the production and absorption of cholesterol in the body, specifically targeting "bad" cholesterol, or low-density lipoprotein (LDL). Varieties such as shiitake, maitake, and reishi are particularly beneficial for lowering cholesterol. The fibre content in mushrooms, including beta-glucans, also contributes to reducing cholesterol levels and maintaining heart health.
Blood Pressure
Mushrooms are naturally low in sodium and rich in potassium, making them an excellent food for managing blood pressure. The low sodium content helps reduce excess fluid retention, which is a contributing factor to high blood pressure. Additionally, potassium helps regulate blood pressure and can decrease the risk of hypertension. Mushrooms also contain heart-healthy compounds and beta-glucans, which have been associated with lower blood pressure levels and improved circulation.

Taste and texture: savoury flavour, versatility, and preparation
Mushrooms are known for their savoury, earthy flavour and meaty texture, making them a popular meat substitute in vegetarian and vegan dishes. They are versatile and can be used in a wide variety of dishes, including soups, stews, stir-fries, pasta, sandwiches, burgers, and pizzas.
The taste and texture of mushrooms vary depending on the species and cooking method. For example, raw mushrooms tend to have a "woody" or "grassy" flavour, while cooked mushrooms may take on a firmer, meatier texture and a richer, more savoury flavour.
Some common edible mushrooms include Portobello, Shitake, Oyster, Lion's Mane, Enoki, Maitake, Morel, and Porcini. Portobello mushrooms are known for their dense, steak-like texture and robust flavour, making them a popular meat substitute in sandwiches, burgers, and pizzas. Oyster mushrooms have a mild, creamy, seafood-like flavour and a versatile texture that can mimic meat. Lion's Mane mushrooms are juicy and tender when cooked and are often used as a seafood substitute in vegan dishes. Enoki mushrooms have thin stalks and a crisp texture, making them ideal for salads or ramen. Maitake mushrooms have a delicate, feathery texture and a rich, savoury flavour with a slight hint of spice. Morel mushrooms have an earthy, nutty flavour that can be enhanced by cooking methods such as grilling or smoking. Porcini mushrooms have a distinct, creamy, nutty flavour and a firm, meaty texture, making them sought-after in Italian cuisine.
When preparing mushrooms, it is important to note that they are highly absorbent and will take on the flavours of other ingredients. This makes them versatile and easy to season to elevate their taste. However, it is crucial not to crowd mushrooms in a pan during cooking, as they have a high water content and can become squishy and gelatinous if too many are cooked at once. Cooking them in smaller batches or using a larger pan can help achieve a firmer, more savoury texture.

Psychoactive properties: hallucinations, anxiety, and paranoia
Magic mushrooms, or mushrooms that contain the hallucinogenic compound psilocybin, have been known to induce hallucinations, anxiety, and paranoia in users. While the effects of psilocybin mushrooms are highly variable, they are believed to be influenced by several factors, including dosage, age, weight, personality, emotional state, environment, and history of mental illness.
Psilocybin is a Schedule I substance in the United States, meaning that it is considered to have a high potential for abuse and no legitimate medical purpose. However, current research suggests that psilocybin is not addictive, and no physical symptoms occur after stopping use. The compound is naturally occurring and is found in approximately 200 species of mushrooms, including the liberty cap (Psilocybe semilanceata).
When consumed, psilocybin can induce hallucinations, sensory distortion, and euphoria. However, it can also cause negative side effects such as anxiety, paranoia, and short-term psychosis. The risk of experiencing these negative effects may be influenced by factors such as mental health, setting, quantity, and expectations. For example, feelings of stress or anxiety before using magic mushrooms may result in a "bad trip". Additionally, consuming higher doses of psilocybin or taking it in combination with other substances can increase the risk of adverse effects.
While psilocybin mushrooms have been primarily associated with recreational use, there has been a recent resurgence of interest in their potential therapeutic applications, particularly in the fields of mental health and addiction treatment. Some researchers believe that psilocybin therapy could transform how we treat conditions like severe depression and substance addiction. However, it is crucial to acknowledge the potential side effects and risks associated with psilocybin consumption and to ensure that any therapeutic use is supervised by trained professionals in a controlled clinical setting.

Safety concerns: identifying poisonous mushrooms and adverse effects
Mushrooms are widely known for their health benefits, but they can also be poisonous. Mushroom poisoning is a serious concern, and it is important to be able to identify poisonous mushrooms and be aware of their adverse effects.
Identifying Poisonous Mushrooms
Poisonous mushrooms can be hard to distinguish from edible varieties, and many edible mushrooms look the same as those that can be deadly if eaten. Learning to identify and understand the differences between mushroom varieties can be a difficult skill that takes years to perfect. Some key features to look out for when identifying poisonous mushrooms include the presence of "folds" rather than gills, as in the case of Chanterelles, which can be poisonous if mistaken for Jack O'Lantern mushrooms. True morels, which are edible, can be distinguished from their poisonous counterparts, false morels, by their pitted caps and smooth hollow stems, whereas false morel caps appear wavy and crumpled, and their stems are nearly solid. Another critical reason to bisect mushroom species is to rule out toxic look-alikes; for example, the Giant Puffball is considered edible when fresh, but deadly toxic Amanita virosa and Amanita bisporigera must be ruled out by cutting the puffball in half and examining the colour of the interior.
Adverse Effects of Poisonous Mushrooms
The most common consequence of mushroom poisoning is gastrointestinal upset, including nausea, vomiting, abdominal cramping, and diarrhoea. However, there are also recognised mushroom toxins with specific and sometimes deadly effects. Amatoxin, found in species of Galerina, Lepiota, and Amanita, causes liver toxicity, while Gyromitrin, found in false morels, affects multiple body systems, causing stupor, delirium, muscle cramps, loss of coordination, tremors, seizures, and severe gastrointestinal irritation. Another toxin, coprine, is harmless unless ingested within a few days of consuming alcohol, causing a disulfiram-like reaction with symptoms including headache, nausea, vomiting, flushing, tachycardia, and rarely, hypotension. In addition, muscarine, found in jack o' lantern mushrooms and some Clitocybe and Inocybe species, stimulates the muscarinic receptors of the nerves and muscles, leading to symptoms such as sweating, salivation, tears, blurred vision, palpitations, and respiratory failure in high doses.
It is important to note that patients with mushroom poisoning who receive immediate medical attention have a much better chance of recovery. Hospitalization and aggressive support therapy significantly reduce the mortality rate associated with mushroom poisoning.
