Mushrooms are a nutrient-dense food that provides a range of health benefits. They are low in calories, have virtually no fat or cholesterol, and are very low in sodium. Mushrooms are a good source of antioxidants, vitamins, and minerals, including vitamin D, selenium, B vitamins, potassium, copper, and iron. They also contain an indigestible carbohydrate called chitin, which contributes bulk to the diet. The nutritional profiles of mushrooms vary between types, with some being higher in certain nutrients than others. Mushrooms are a versatile ingredient that can be cooked in various ways and are often used as a meat substitute in vegetarian and vegan dishes.

What You'll Learn
Mushrooms are a good source of vitamin D
The amount of vitamin D in mushrooms can vary 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. In contrast, mushrooms grown in darkened conditions, such as white button, shiitake, and oyster mushrooms, typically contain less than 40 IU. However, exposing button mushrooms to sunlight or UV lamps can significantly increase their vitamin D content, with some studies showing up to 400 IU per 3.5-ounce serving.
The vitamin D content in mushrooms can also depend on factors such as the time of day, season, latitude, and duration of UV exposure. Additionally, the concentration of vitamin D2 generated can vary based on the type and orientation of the mushrooms, whether they are sliced or whole, and the distance from the UV source. It is important to note that cooking mushrooms in fat, such as oils, can cause the vitamin D to leach out due to its fat-soluble nature.
Mushrooms are a valuable source of vitamin D, especially for those following a vegan or vegetarian diet. Vitamin D is commonly found in animal-based foods, such as fish and egg yolks, so mushrooms provide a non-animal alternative. While the vitamin D2 in mushrooms may not be as effective as the vitamin D3 found in animal sources, it still plays a crucial role in raising blood levels of vitamin D and maintaining overall health.

They are low in calories
Mushrooms are low in calories, making them a great food choice for those watching their weight. One cup of mushrooms (70g) provides only 15 calories, along with 2.2g of protein and 0.2g of fat. They are also a good source of copper, B vitamins like riboflavin, niacin, and pantothenic acid, potassium, and iron.
The nutritional profiles of mushrooms vary between types, but most edible varieties contain important vitamins and minerals. For example, white mushrooms have slightly more calcium, while shiitake mushrooms have more fiber. Mushrooms are also one of the few foods that contain vitamin D, which is important for building strong bones, reducing inflammation, and improving immune function. They can even increase their vitamin D content when exposed to ultraviolet light, just like how our skin produces vitamin D when exposed to sunlight.
Mushrooms are incredibly versatile and can be cooked in a variety of ways, including grilling, baking, broiling, sautéing, and roasting. They have a savory, umami flavor that is similar to meat, making them a popular meat substitute for those looking to reduce their meat intake or follow a vegetarian or vegan diet.
When buying fresh mushrooms, choose ones that are firm, dry, and unbruised. They should be stored in the refrigerator and washed or trimmed just before cooking. Mushrooms can be used in sauces, stews, soups, grain dishes, or simply chopped and sautéed as a side dish.

Mushrooms are a source of B vitamins
Mushrooms are a good source of B vitamins, which are essential for overall health and well-being. B vitamins help the body to convert food into energy and impact brain function and cell health. Vitamin B1, or thiamine, is essential for converting carbohydrates into energy and supporting brain function. Thiamine, riboflavin, B6, and B12 are all B vitamins found in mushrooms. Vitamin B12, also known as cobalamin, promotes red blood cell formation, supports healthy brain function, and helps produce DNA. It also helps maintain nerve function and prevents anemia.
Mushrooms are a unique food source because they are a type of fungus, neither a plant nor an animal food. They contain ergosterol, a substance similar to cholesterol in animals that can be converted into vitamin D when exposed to ultraviolet light. Vitamin D is important for bone and teeth health, immune function, and regulating mood. Some mushrooms are cultivated in the dark and have little to no vitamin D, but those exposed to sunlight or UV light during cultivation will have higher levels.
Mushrooms are also a good source of antioxidants, vitamins, minerals, and protein. They are low in calories, fat, cholesterol, and sodium, making them a healthy food choice. The Environmental Working Group has listed mushrooms as one of the cleanest foods in terms of pesticide content, although they should still be carefully cleaned before use. When buying fresh mushrooms, choose ones that are firm, dry, and unbruised. Store them in the refrigerator and do not wash or trim them until it is time to cook.
Mushrooms have been eaten and used as medicine for thousands of years. They are considered a superfood or functional food due to their many health benefits and bioactive compounds. They can be used as a meat substitute in recipes, providing a similar taste and texture profile while helping to reduce meat intake. Overall, mushrooms are a nutritious food source that contributes to a healthy and balanced diet.

They are rich in antioxidants
Mushrooms are a good source of antioxidants, which can help to protect the body from cancer and reduce inflammation. They contain bioactive compounds such as polyphenols, polysaccharides, vitamins, carotenoids, and minerals, which give them their antioxidant properties. These compounds can help to regulate oxidative homeostasis in the body, reducing the risk of various health disorders caused by oxidative stress.
Edible mushrooms, including those that are wild or cultivated, have been found to possess significant antioxidant properties. This has led to a growing interest in using mushrooms as a natural source of antioxidants for dietary supplementation. The antioxidant potential of mushrooms has been well-studied, and they are known to exhibit strong antioxidant effects on different radicals.
Mushrooms are also one of the few foods that contain vitamin D, which is important for bone health and immune function. When exposed to ultraviolet light, mushrooms can increase their vitamin D content, similar to how human skin produces vitamin D when exposed to sunlight. This makes them an even more valuable source of this essential nutrient.
In addition to their antioxidant properties, mushrooms have gained attention for their therapeutic benefits. They have been associated with biological activities such as antitumor, antiviral, anticoagulant, antidiabetic, and immunostimulant properties. These characteristics make mushrooms valuable not only in food but also in cosmetics, biomedicine, and environmental protection.
The specific types of mushrooms can also influence their antioxidant content. For example, cremini and portobello mushrooms are known to have higher levels of the antioxidant ergothioneine, while oyster and shiitake mushrooms are richer in fiber. Overall, mushrooms provide a range of antioxidants that contribute to their nutritional and therapeutic value, making them a popular choice for maintaining health and longevity.

Mushrooms are a good meat substitute
Mushrooms are low in calories and contain very little fat, no cholesterol, and low levels of sodium. They are a good source of B vitamins, selenium, zinc, and potassium. They also contain antioxidants and anti-inflammatory phytochemicals, which may have anti-cancer and anti-ageing properties.
When substituting mushrooms for meat, it is important to note that they are not a direct replacement for protein. However, they can be combined with other plant-based protein sources like beans, tempeh, tofu, or seitan to create a balanced meal.
Some popular ways to use mushrooms as a meat substitute include slicing and searing King Oyster mushrooms to use in place of scallops, or shredding Lions Mane mushrooms to use like crab meat. Breaded oyster mushrooms can be a good substitute for schnitzel, and when shredded, they can be used in a "pulled pork" sandwich. White button mushrooms, cremini, and portobello mushrooms are also good meat substitutes in pasta sauces, stews, and on pizzas.
Mushrooms can be blended with meat or used as a full meat replacement, depending on personal preference. They are a versatile and nutritious option for those looking to reduce their meat consumption.
