What You'll Learn
Mushrooms are a good source of vitamin D
Mushrooms exposed to ultraviolet light are a good source of vitamin D. The most common form of vitamin D in mushrooms is D2, with lesser amounts of vitamins D3 and D4. Vitamin D2 is the form of vitamin D found in fungi, while D3 is primarily sourced from animals or algae. Mushrooms are the only vegan, non-fortified dietary source of vitamin D, making them a good option for those avoiding animal products.
The vitamin D content in mushrooms can be increased by exposing them to UV light or sunlight. Certain mushrooms, such as white button mushrooms, have been found to generate more vitamin D when exposed to UV light. This process involves using a pulsed UV lamp to generate vitamin D2 within the 'flesh' of the mushroom. The concentration of vitamin D2 produced depends on various factors, including the type and orientation of the mushrooms, the distance from the lamp, and the number of pulses received.
While most commercially grown mushrooms are cultivated in the dark and lack vitamin D, some growers use ultraviolet light to produce vitamin D-rich mushrooms. When purchasing mushrooms, it is important to check the nutrition facts panel to ensure they contain vitamin D, as not all commercially available mushrooms are rich in this nutrient.
In summary, mushrooms are a good source of vitamin D, especially when exposed to UV light or sunlight. They are the only produce that contains vitamin D and provide a vegan source of this important nutrient. By including mushrooms in your diet and ensuring adequate sun exposure or purchasing UV-treated mushrooms, you can increase your vitamin D intake and contribute to overall bone and immune health.

They are rich in potassium, B vitamins, and selenium
Mushrooms are a type of fungus, often considered a vegetable, that are native to North America and Europe. They are known for their delicate flavour and meaty texture. They are also packed with essential vitamins and minerals, making them an excellent addition to a healthy diet.
One of the key nutrients found in mushrooms is potassium. Mushrooms are a rich source of this mineral, which is known for reducing the negative impact of sodium on the body. Potassium helps to lessen the tension in blood vessels, thereby potentially lowering blood pressure. This makes mushrooms an excellent ingredient to use in recipes that call for saltier ingredients, helping to reduce sodium intake.
Mushrooms are also a good source of B vitamins, including riboflavin (vitamin B2), thiamine (vitamin B1), niacin, biotin, and vitamin C. B vitamins are important for several functions in the human body, and mushrooms have long been used for their medicinal value, particularly in oriental cultures. The shiitake mushroom, for example, has been used medicinally in Japan and other Asian countries for over 2000 years.
In addition to potassium and B vitamins, mushrooms contain selenium, an essential nutrient for human health. Selenium is needed for the biosynthesis of selenoenzymes and selenoproteins, which play a role in antioxidant defence, detoxification, immunomodulation, and thyroid functioning, among other activities. Selenium-enriched mushrooms have been linked to the treatment and prevention of various conditions, including cancer, cardiovascular disease, and immunological diseases. However, it is important to note that selenium can be toxic at elevated concentrations, so the cultivation of selenium-fortified mushrooms is carefully considered to ensure optimal nutritional benefits.

Mushrooms are a low-calorie food
Mushrooms are an excellent substitute for meat, particularly red meat, in recipes. They help to reduce calories and fat intake while keeping the meal just as satisfying. For instance, a study found that swapping half the meat for mushrooms in a traditional ground beef recipe reduced sodium intake by 25% without compromising on flavour.
Mushrooms are also a good source of vitamins, minerals, and antioxidants, which can have various health benefits. They are one of the few dietary sources of vitamin D, which is important for bone health and immune function. Additionally, mushrooms are rich in potassium, which helps to reduce the negative impact of sodium on the body and can potentially lower blood pressure.
When it comes to cooking mushrooms, sautéing, boiling, grilling, and baking are healthier options compared to frying or battering. The volume of mushrooms decreases significantly after cooking, especially if they are cooked with oil or other ingredients.
Overall, mushrooms are a nutritious and flavourful addition to any diet, offering a range of health benefits while being low in calories.

They are a source of protein and fibre
Mushrooms are a type of fungus, often considered a vegetable, that has been consumed and used as medicine for thousands of years. They are a rich source of protein and fibre, along with various vitamins, minerals, and antioxidants.
Protein is an essential macronutrient that serves as a building block for muscles, skin, hair, and other tissues in the body. It also helps produce enzymes and hormones, which are vital for maintaining overall health. Mushrooms, despite being low in calories, provide a good amount of plant-based protein. This makes them an excellent option for individuals following vegetarian or vegan diets, as well as those looking to increase their protein intake without consuming excessive calories or fat.
Fibre, also known as dietary fibre, is a type of carbohydrate that the body cannot fully digest or absorb. It is essential for maintaining a healthy digestive system, promoting regular bowel movements, and supporting the growth of beneficial gut bacteria. Mushrooms contain a specific type of soluble fibre called beta-glucan, which has immune-boosting properties. Beta-glucan activates certain parts of the immune system, enhancing the body's ability to fight infections and potentially inhibiting the growth of tumours.
In addition to their protein and fibre content, mushrooms are also a good source of B vitamins, including B2, B3, B5, B6, B9 (folate), and B12. These vitamins play a crucial role in cell growth and formation, contributing to healthier hair, skin, nails, brain, and heart. Mushrooms are also one of the few non-animal sources of vitamin D, which is essential for bone health and strengthening the immune system.
When incorporating mushrooms into your diet, it is important to choose edible varieties and ensure proper preparation. Wild mushrooms, while offering tasty and nutritious options, require careful identification to avoid toxic species. Farm-grown mushrooms from supermarkets are generally safe and can be eaten raw or cooked, adding flavour and texture to various dishes.

Mushrooms may help to prevent cancer
Mushrooms are a nutritious food with a delicate flavour and meaty texture. They are low in calories and packed with vitamins, minerals, protein, and antioxidants. They are also the only vegan, non-fortified dietary source of vitamin D.
Mushrooms have been shown to have anti-inflammatory effects, improve immune system efficiency, and lower blood pressure. They may also help to lessen the risk of developing serious health conditions, such as Alzheimer's, heart disease, cancer, and diabetes.
Mushrooms are being studied for their potential to prevent and treat cancer. They are rich in ergothioneine, an amino acid and antioxidant that prevents or slows cellular damage. A review of 17 cancer studies found that eating just 18 grams of mushrooms daily may lower your risk of cancer by up to 45%.
Shiitake mushrooms, in particular, have been found to keep cholesterol levels low. They contain compounds that inhibit the production and absorption of cholesterol and lower overall cholesterol levels in the blood. Additionally, shiitake extracts like lentinan, a type of beta glucan, may stimulate the immune system to attack cancer cells. In laboratory studies, lentinan has been shown to slow the growth of some cancer cells and improve the quality of life for lung cancer patients.
Maitake mushrooms have been used in Japan and China to treat diabetes and hypertension. They are also being studied for their potential to slow the growth of breast cancer cells and exhibit anti-cancer effects on skin, lung, and prostate cancer cells.
A Brazilian study on Agaricus sylvaticus mushrooms found that consuming these mushrooms after bowel cancer surgery improved participants' quality of life compared to those who did not consume the mushrooms.
While the medicinal use of mushrooms has been prevalent in Asia for a long time, their use for treating cancer has increased in other parts of the world in recent decades. However, it is important to note that more clinical research is needed to confirm the preventive and therapeutic aspects of mushrooms in cancer treatment.
