Mushrooms: Nutrition, Health Benefits and Everyday Uses

What are Mushrooms? How it can be defined?

Mushrooms are wonderful organisms that belong to the fungi kingdom. Unlike plants, they don’t photosynthesize or produce seeds to propagate. Instead, they spread through spores, which are tiny cells released into the air, similar to pollen. Once these spores settle, they grow and mature, often thriving in soil or decaying wood.

Although mushrooms are often classified as vegetables for culinary purposes, they have unique characteristics that set them apart from typical plant foods. Edible mushrooms, like button, oyster, porcini and chanterelle, are popular in many cuisines. However, not all mushrooms are safe to eat; some varieties, like the infamous death cap, are toxic and can lead to severe illness or even death if consumed. Therefore, knowing which types of mushrooms are safe is essential for anyone interested in foraging or experimenting with wild mushrooms.

Nutritional Profile of Mushrooms

Mushrooms are low in calories yet packed with valuable nutrients. Here’s what an 80-gram serving of mushrooms typically provides:

• Calories: 6 Kcal
• Protein: 0.8 grams
• Fat: 0.2 grams
• Carbohydrates: 0.2 grams
• Fiber: 0.6 grams
• Potassium: 302 mg
• Folate: 32 mcg

An 80-gram serving of mushrooms, roughly equivalent to 14 button mushrooms, counts as one of your recommended daily five servings of fruits and vegetables.

Top 5 Health Benefits of Mushrooms

1. A Natural Source of Vitamin D

One unique aspect of mushrooms is their ability to provide vitamin D, a nutrient typically derived from sunlight or animal sources. When mushrooms are exposed to UV light, they can increase their vitamin D content, making them one of the few plant-based sources of this essential nutrient. This can even be done at home by leaving mushrooms in direct sunlight for 15 to 120 minutes, which can enhance their vitamin D2 levels significantly.

2. Immune System Support

Mushrooms contain beta-glucan, a type of soluble fiber known for its immune-modulating properties. Beta-glucans stimulate immune cells like macrophages and natural killer cells, enhancing the body’s defense against infections and potentially inhibiting the growth of certain tumors. Additionally, mushrooms are a good source of B vitamins and selenium, both of which play a role in supporting immune health and protecting cells from damage.

3. Possible Benefits for Brain Health

Some varieties of mushrooms, especially “medicinal” mushrooms like lion’s mane and reishi, have gained attention for their potential effects on neurodegenerative conditions. Research suggests that these mushrooms may offer benefits in the treatment and management of diseases like Alzheimer’s. While they are often consumed in powdered or supplement form, their unique compounds make them a promising focus in the field of brain health.

4. Heart Health

Mushrooms have been found to have properties that support heart health by helping to lower cholesterol levels, particularly in individuals who are overweight. Compounds in mushrooms may prevent the accumulation of plaque on blood vessel walls, supporting healthy blood flow and reducing blood pressure. These qualities make mushrooms a heart-friendly addition to any diet.

5. Gut Health and Digestion

Mushrooms contain substances such as beta-glucans that function as prebiotics, encouraging the development of helpful bacteria in the intestines. A healthy gut is essential for effective digestion, a strong immune system and healthy communication between the gut and the brain. By promoting a balanced gut environment, mushrooms can play a valuable role in overall digestive health.

Functional Mushrooms and Their Medicinal Properties

“Functional mushrooms” are types of edible mushrooms that possess distinctive medicinal attributes. Some of these mushrooms, such as lion’s mane, turkey tail and cordyceps are used in alternative medicine for their potential health benefits. These mushrooms have shown promising effects in research, from supporting immune function to potentially acting as adaptogens, which help the body manage stress. As research on these functional mushrooms continues, they may become more widely recognized for their potential to enhance well-being.

Are Mushrooms Safe for Everyone?

Generally, mushrooms purchased from reliable sources are safe for most people, as long as there are no allergies to mushrooms or molds. However, with the increasing popularity of foraging, there is a higher risk of consuming toxic varieties. Foraging should only be done with an experienced guide, as certain wild mushrooms look similar to edible types but can be harmful if ingested. Cooking mushrooms is also recommended, as raw mushrooms can sometimes be harder to digest or cause mild reactions.

One specific variety, known as “magic mushrooms” or psilocybin mushrooms, can cause hallucinations and other sensory distortions. These mushrooms contain the compound psilocybin, which acts as a powerful psychedelic. It’s important to note that psilocybin mushrooms are classified as a controlled substance in many regions, including the UK, where it is illegal to possess, distribute or sell them.

How to Choose and Store Mushrooms

When selecting mushrooms, look for ones that feel firm, have a dry surface and are free from mold. Fresh mushrooms should be stored in a paper bag in the refrigerator, which can help them stay fresh for up to five days. Before use, brush off any dirt and rinse them briefly.

Some common types of mushrooms found in stores include:

• Shiitake
• Portobello
• Crimini (baby bella)
• Button (white mushroom)
• Oyster
• Enoki
• Beech
• Maitake

Each of these varieties has a distinct flavor and texture, making mushrooms a versatile ingredient that can add depth and richness to a range of dishes without adding fat or sodium.

Nutritional Benefits of Mushrooms

Mushrooms offer a range of nutritional benefits, including several key nutrients that support overall health:

• Antioxidants: Mushrooms contain selenium, an antioxidant that helps protect the body from free radicals that can lead to diseases like cancer and heart disease. Selenium also plays a role in immune function and may help slow the aging process.
• Beta Glucan: As a soluble fiber, beta-glucan is known for its ability to improve cholesterol levels and regulate blood sugar. This compound is particularly abundant in varieties like oyster and shiitake mushrooms.
• B Vitamins: Mushrooms are rich in B vitamins, including riboflavin, niacin and pantothenic acid. These vitamins are vital for energy production, healthy skin, nerve function and red blood cell production.
• Copper: This mineral is essential for red blood cell production and maintaining strong bones and nerves. A single cup of cooked mushrooms can supply about one-third of the recommended daily intake of copper.
• Potassium: Known for its role in heart and muscle function, potassium levels in mushrooms are comparable to those in bananas, making mushrooms a valuable source of this mineral.

Are Mushrooms Good for You?

Mushrooms are a nutrient-dense addition to a balanced diet, offering multiple health benefits without adding extra calories, sodium or fat. They’re especially beneficial for heart health, immune function and gut health, making them a versatile ingredient for people of all dietary backgrounds. For those looking to add more nutrients to their diet naturally, mushrooms are a powerhouse of antioxidants, vitamins and minerals. Whether enjoyed fresh, cooked or even in supplement form, mushrooms can contribute to a healthier lifestyle when incorporated thoughtfully into daily meals.
