Mushrooms are a good source of vitamin D, especially when exposed to UV light
Vitamin D is essential for maintaining and building strong bones, as it helps the body absorb calcium. Mushrooms are one of the few non-animal sources of this vital nutrient, making them a valuable addition to a plant-based diet. The amount of vitamin D present in mushrooms varies depending on their exposure to UV light. Wild mushrooms like chanterelles and morels, 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, contain less than 40 IU. However, exposing these mushrooms to UV light can significantly increase their vitamin D content. For example, white button mushrooms exposed to sunlight can produce up to 400 IU of vitamin D per 3.5-ounce serving.
To enhance the vitamin D content of mushrooms at home, they can be placed in direct sunlight for 15 to 120 minutes. Studies suggest that this simple method can result in levels of vitamin D2 as high as 10 mcg per 100g of fresh mushrooms. Mushrooms that provide the most vitamin D after UV or sunlight exposure include white button, portabella, and cremini mushrooms. Consuming sliced mushrooms exposed to sunlight for at least 15 minutes is an easy way to ensure adequate vitamin D intake.
In addition to their vitamin D content, mushrooms offer a range of other nutritional benefits. They are a good source of selenium, an antioxidant that helps protect body cells from damage, reducing the risk of chronic diseases, heart disease, and certain cancers. Mushrooms also contain ergothioneine, a powerful antioxidant amino acid that prevents or slows cellular damage. Additionally, mushrooms provide B vitamins, including thiamine, riboflavin, B6, and B12, which are essential for various bodily functions. Mushrooms are also a rich source of potassium, which helps control blood pressure and maintain normal fluid and mineral balance in the body.
Overall, mushrooms are a nutritious food item that can be a valuable source of vitamin D, especially when exposed to UV light. They offer a range of additional health benefits, including antioxidants, vitamins, and minerals, making them a beneficial addition to a balanced diet.

They contain selenium, which acts as an antioxidant and supports the immune system
Mushrooms are a type of fungus that contains a substance called ergosterol, which is structurally similar to cholesterol in animals. They have been eaten and used as medicine for thousands of years. Mushrooms are a good source of selenium, an antioxidant that helps to protect the body's cells from damage. This damage could potentially lead to heart disease, certain cancers, and other diseases associated with ageing. Selenium also supports the immune system and is important for male fertility.
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 the tension in blood vessels. They are also a good source of vitamin B6, which helps the body form red blood cells, proteins, and DNA.
Vitamin D is another important nutrient found in mushrooms. While fresh wild mushrooms like chanterelles and morels can contain up to 1200 IU of vitamin D per 3.5-ounce serving, mushrooms grown in dark conditions typically contain less. However, exposing these mushrooms to ultraviolet (UV) light or sunlight can significantly increase their vitamin D content. Vitamin D helps with cell growth and boosts immune function, making it an important component for bone and immune health.
In addition to their nutritional benefits, mushrooms are a good substitute for meat in recipes due to their umami flavour. They are naturally low in calories, fat, sodium, and cholesterol, making them a healthy addition to any diet.

They are a good source of B vitamins, including thiamine, riboflavin, B6, and B12
Mushrooms are a rich source of B vitamins, including thiamine, riboflavin, B6, and B12. B vitamins play an important role in energy production, helping the body derive energy from food, and forming red blood cells. They are also important for brain health.
Among the B vitamins, thiamine (B1) contributes to healthy nerve function and the metabolism of carbohydrates, while riboflavin (B2) is involved in energy production and the metabolism of fats and drugs. Vitamin B6, as mentioned earlier, is crucial for red blood cell formation and also plays a role in cognitive development and immune function.
Vitamin B12, on the other hand, is particularly important for those following a plant-based diet, as it is typically found in animal products. B12 is involved in the production and maintenance of myelin, which surrounds nerve cells, and it also contributes to mental ability, red blood cell formation, and the breakdown of fatty acids and amino acids for energy production. While B12 is generally low in most mushroom varieties, oyster mushrooms are a notable source of this vitamin, and shiitake mushrooms are known to contain even higher levels of B12. Consuming 50 grams of dried shiitake mushrooms can meet the daily recommended intake of B12.
In addition to their B vitamin content, mushrooms are also a good source of other nutrients, including potassium, vitamin C, fiber, vitamin D, selenium, and antioxidants. These nutrients contribute to overall health and may offer specific benefits such as improved heart health, reduced risk of cancer, and enhanced immune function.
It is worth noting that cooking methods can impact the nutrient content of mushrooms. High-temperature cooking methods, such as boiling or microwaving, may cause water-soluble vitamins like B vitamins to escape into the cooking water. Therefore, it is recommended to sauté or simmer mushrooms over low heat to preserve their nutrient content.
