Some sources have suggested that selenium may help prevent cancer, but a Cochrane review, from 2017, found no evidence to confirm this.
Mushrooms also contain a small amount of vitamin D. There is some evidence that vitamin D supplementation may help prevent or treat some kinds of cancer, though according to a 2018 report, the effect may vary from person to person.
Choline is another antioxidant in mushrooms. Some studies have suggested that consuming choline can reduce the risk of some types of cancer, but at least one other study has indicated that it may increase the risk of prostate cancer.
It is worth noting that consuming a nutrient as a supplement is not the same as consuming it in the diet.
What links are there between cancer and the diet?
Dietary fiber may help manage a number of health conditions, including type 2 diabetes.
A 2018 review of meta-analyses concluded that people who eat a lot of fiber may have a lower risk of developing type 2 diabetes. For those who already have it, fiber may help reduce blood glucose levels.
A cup of sliced, raw mushrooms, weighing 70 grams (g), provides almost 1 g of fiber.
The Dietary Guidelines for Americans recommend that adults consume 22.4–33.6 g of dietary fiber each day, depending on sex and age.
Mushrooms, beans, some vegetables, brown rice, and whole-grain foods can all contribute to a person’s daily requirement of fiber.
The fiber, potassium, and vitamin C in mushrooms may contribute to cardiovascular health.
Potassium can help regulate blood pressure, and this may decrease the risk of hypertension and cardiovascular disease. The American Heart Association (AHA) recommend reducing the intake of added salt in the diet and eating more foods that contain potassium.
According to current guidelines, people should consume around 4,700 milligrams (mg) of potassium each day. Mushrooms appear on the AHA’s list of foods that provide potassium.
A 2016 study concluded that people with a vitamin C deficiency were more likely to experience cardiovascular disease and suggested that consuming vitamin C may help prevent this illness. They did not find evidence that vitamin C supplements can reduce the risk of this type of disease.

Mushrooms are rich in B vitamins, such as:
B vitamins help the body get energy from food and form red blood cells. A number of B vitamins also appear to be important for a healthy brain.
The choline in mushrooms can help with muscle movement, learning, and memory. Choline assists in maintaining the structure of cellular membranes and plays a role in the transmission of nerve impulses.
Mushrooms are also the only vegan, nonfortified dietary source of vitamin D.
Several other minerals that may be difficult to obtain from a vegan diet — such as selenium, potassium, copper, iron, and phosphorus — are available in mushrooms.
