They have vitamin D and B12
White button mushrooms are low in calories, with 8 ounces containing approximately 20 to 21 calories. They are also a good source of vitamins and minerals, notably including vitamin D and vitamin B12.
Vitamin D is essential for maintaining healthy bones and preventing osteoporosis, mineralization defects, and muscle weakness. White button mushrooms, when exposed to UV rays or sunlight, become a natural, non-animal source of vitamin D2. This form of vitamin D can be converted by the body into its active form, which is necessary for calcium absorption and bone health.
Vitamin B12, typically found in animal sources, is also present in white button mushrooms. This makes them an excellent option for individuals following a plant-based or vegan diet, ensuring they obtain this vital nutrient. Vitamin B12 is important for maintaining healthy blood and nerve cells and preventing anaemia.
The presence of vitamins D and B12 in white button mushrooms adds to their nutritional value and makes them a beneficial addition to a balanced diet. These vitamins contribute to the overall health benefits associated with mushroom consumption, including improved heart health, cholesterol-lowering effects, and potential cancer-fighting properties due to their antioxidant content.
In summary, white button mushrooms are not only low in calories but also provide essential vitamins and minerals. The presence of vitamins D and B12 in these mushrooms makes them a nutritious choice, particularly for those following plant-based diets, as they help support bone health, healthy blood and nerve cell function, and overall well-being.

They are high in fibre
White button mushrooms are a great, low-calorie food option. They are also a good source of fibre, which is beneficial for digestive health and can help lower cholesterol levels. Fibre is also beneficial for maintaining a healthy weight as it helps you feel full for longer.
A serving of 8 oz of white button mushrooms contains 20 calories, with 3 grams of carbohydrates and 1 gram of sugar. White button mushrooms are also a good source of protein, with 2.2 grams per serving, and low in fat, with 0.5 grams.
White button mushrooms are also known for their high fibre content. Fibre is a type of carbohydrate that cannot be digested by the body, but it plays an important role in maintaining regular bowel movements and a healthy digestive system. The recommended daily intake of fibre for adults is 25-30 grams, and including high-fibre foods like white button mushrooms can help ensure adequate intake.
In addition to their high fibre content, white button mushrooms also contain other essential nutrients. They are a good source of vitamin D, which is important for bone health and immune function. White button mushrooms also contain vitamin B12, which is commonly found in animal sources, making it a valuable nutrient for those following a plant-based diet.
The high fibre content in white button mushrooms can also have beneficial effects on cholesterol levels. Fibre can help lower low-density lipoprotein (LDL), or "bad" cholesterol, by interfering with its absorption in the intestines. This can lead to a reduced risk of heart disease and other cardiovascular issues associated with high cholesterol levels.

They have cancer-fighting properties
An 8 oz serving of white button mushrooms contains 21 calories. White button mushrooms are not only low in calories but also have cancer-fighting properties.
White button mushrooms (Agaricus bisporus) are the most cultivated edible mushrooms worldwide. They are widely consumed due to their nutritional value and medicinal properties. Mushrooms have been used in traditional Chinese medicine to treat illnesses for centuries.
The potential cancer-fighting properties of white button mushrooms can be attributed to multiple antioxidant compounds, including polyphenols, polysaccharides, ergothioneine, glutathione, selenium, and vitamin C. These antioxidants help combat oxidative stress, which can lead to cellular damage and an increased risk of cancer.
Research has shown that white button mushroom extract can shrink tumors and delay their growth. In a human clinical trial, the extract was found to slow tumor growth and enhance the effectiveness of cancer-fighting immune cells. Specifically, the extract interrupts androgen receptor (AR) signaling, inhibiting DHT-induced AR translocation, preventing co-activator binding, attenuating transcriptional activity, and ultimately suppressing the expression of prostate-specific antigen (PSA) and androgen-dependent cell cycle progression.
Additionally, white button mushrooms have cytotoxic effects on cancer cells and can enhance the immune system by activating lymphocytes, NK cells, and macrophages, increasing cytokine production, reducing cancer cell growth, boosting apoptosis, and blocking angiogenesis.
While the cancer-fighting abilities of white button mushrooms are promising, it is important to note that there is currently no evidence that they can cure or prevent cancer. More research and clinical trials are needed to fully understand their potential in cancer treatment and care.
