What You'll Learn
Mushrooms are low in calories and fat
Mushrooms are a low-calorie food, with one serving (about a cup raw or half a cup cooked) containing only about 15 calories. They are also low in fat, with some sources claiming that they contain practically no fat. This makes them a great low-fat alternative to meat, as their savoury, umami flavour is similar to meat. Mushrooms can be used as a substitute for meat in many dishes, and they are also a good source of plant-based protein.
Mushrooms are a good addition to a healthy diet as they are packed with essential vitamins, minerals, and antioxidants. They are a source of vitamin D, which is important for bone and immune health, and they also contain vitamin B6, folate, magnesium, zinc, and potassium. Mushrooms are also a rich source of potassium, which is known for reducing the negative impact that sodium can have on the body and helping to lower blood pressure. They are also low in sodium, which can further help to keep blood pressure low.
The antioxidants in mushrooms, such as ergothioneine and selenium, are anti-inflammatory compounds, which can be beneficial for people with minor inflammation or autoimmune disorders. Mushrooms are also being studied for their potential to ward off chronic diseases and improve everyday health. For example, a review of 17 cancer studies found that eating just 18 grams of mushrooms a day may lower your risk of cancer by as much as 45%.
While mushrooms are low in calories and fat, they are not a "magic bullet" for health and should be consumed as part of a balanced diet. It is also important to note that not all mushrooms are edible, and some wild mushrooms can be poisonous or contain toxins. When buying fresh mushrooms, choose ones that are firm, dry, and unbruised, and avoid those that appear slimy or withered.

They are a good source of vitamins and minerals
Mushrooms are a good source of several important vitamins and minerals, which contribute to their overall nutritional value and health benefits. Here are some key vitamins and minerals found in mushrooms:
- Vitamin D: Mushrooms are one of the few natural sources of vitamin D in the produce aisle. Vitamin D is essential for bone health, immune function, and mood regulation. Just like humans, mushrooms can synthesize vitamin D when exposed to sunlight or UV light. The ergosterol present in mushrooms converts to vitamin D2 when exposed to UV light, making them an excellent source of this vital nutrient.
- B Vitamins: Mushrooms contain a range of B vitamins, including riboflavin, niacin, and pantothenic acid. B vitamins are crucial for energy metabolism, nervous system function, and the production of red blood cells. They also help reduce the risk of certain types of anemia and support healthy skin, hair, and nails.
- Selenium: Selenium is a mineral with powerful antioxidant properties, and mushrooms are an excellent source of it. Selenium plays a vital role in immune function, thyroid health, and the protection of cells from oxidative stress. Adequate selenium intake is associated with a reduced risk of certain types of cancer and improved heart health.
- Potassium: Mushrooms are a good source of potassium, an essential mineral that helps regulate blood pressure and heart function. Potassium is also important for muscle contraction, nerve transmission, and maintaining fluid balance in the body. A adequate intake of potassium can help offset some of the negative effects of sodium on blood pressure and may reduce the risk of stroke and kidney stones.
- Copper: Copper is a mineral found in mushrooms that plays a role in energy production, connective tissue health, and the functioning of the immune and nervous systems. It also contributes to iron utilization in the body, helping with the formation of red blood cells and ensuring adequate oxygen transport throughout the body.
- Phosphorus: Mushrooms are a source of phosphorus, a mineral that works closely with calcium and vitamin D to support bone health. Phosphorus is also involved in energy metabolism and plays a role in maintaining the body's pH balance.

Mushrooms are a healthy meat substitute
Mushrooms are also a good source of plant-based protein, with some varieties containing more protein than most vegetables. For instance, oyster and shiitake mushrooms have the most fiber, with 2g per serving. Additionally, mushrooms are a good source of antioxidants, which offer anti-inflammatory benefits and can help protect against chronic diseases.
The versatility of mushrooms in culinary applications makes them a popular choice for those looking to reduce their meat consumption. They can be used as a meat substitute in a variety of dishes, including burgers, sausages, spaghetti sauce, tacos, and sandwiches. For example, oyster mushrooms can be shredded and used as a substitute for pulled pork in sandwiches, or sliced and sautéed with onions and sauce for a "beef" crumble in spaghetti.
Mushrooms also have a low environmental footprint, requiring fewer natural resources than conventional livestock farming. As consumer demand for sustainable and ethical food alternatives grows, mushrooms are becoming an increasingly popular meat substitute.
However, it is important to note that mushrooms do not contain as much protein as meat, and those who exercise may need to add other protein sources to their diet, such as beans or tofu, when using mushrooms as a meat substitute.

They are a good source of vitamin D
Mushrooms are a good source of vitamin D, specifically vitamin D2. Vitamin D is essential for health, but it can be hard to get enough of it from your diet. Vitamin D2 from mushrooms may not be as effective as vitamin D3, which is found in animal products, but it can still help raise blood levels of vitamin D. Vitamin D2 is also suitable for vegetarians and vegans who want to avoid animal-based sources of vitamin D.
Mushrooms are a type of fungus that contains a substance called ergosterol, which is similar in structure to cholesterol in animals. When exposed to ultraviolet (UV) light, ergosterol is converted into vitamin D2. This can happen when mushrooms are exposed to natural sunlight or artificial UV lamps. The amount of vitamin D2 produced depends on the duration and intensity of UV exposure.
Not all mushrooms contain vitamin D. Commercially grown mushrooms are often cultivated in dark environments and, therefore, lack vitamin D. However, some growers use UV light to increase the vitamin D content of their mushrooms. Wild mushrooms, such as chanterelles and morels, can contain up to 1200 IU of vitamin D per 3.5-ounce serving due to their exposure to sunlight.
It is important to note that cooking mushrooms in fat, such as oils, can cause vitamin D to leach out because it is fat-soluble. However, humidity and cooking mushrooms in water do not appear to affect their vitamin D content. Additionally, dried mushrooms can retain their vitamin D content if stored in cool, dark, and dry conditions.
Overall, mushrooms exposed to UV light are a valuable source of vitamin D, especially for those who follow a plant-based diet. By including UV-exposed mushrooms in their diet, individuals can increase their vitamin D intake and contribute to maintaining adequate vitamin D status.

Mushrooms contain antioxidants
Mushrooms are a healthy meat substitute because they are low in calories, fat, and cholesterol. They are also a good source of vitamins, minerals, and protein.
Mushrooms contain a variety of antioxidants, including ergothioneine, selenium, polyphenols, polysaccharides, carotenoids, and vitamins. These antioxidants have anti-inflammatory properties and can help protect cells from damage and inflammation that might lead to chronic diseases.
Ergothioneine (ET) is an unusual sulfur-containing derivative of the amino acid histidine, which is obtained exclusively through diet. Mushrooms are a primary source of ET, containing 400 to 2500 mg/g DW. Cells lacking ET are more susceptible to oxidative stress, which can lead to increased mitochondrial DNA damage, protein oxidation, and lipid peroxidation.
The antioxidant properties of mushrooms have been linked to their traditional use as a popular delicacy food. They have also been studied for their potential application in pharmaceuticals and treating various diseases.
Overall, mushrooms are a nutritious and healthy addition to any diet, offering a range of health benefits due to their antioxidant content.
