Diabetes
Dietary fiber may help manage a number of health conditions, including type 2 diabetes. A 2018 review trusted Source 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 gramsTrusted Source (g), provides almost 1 g of fiber. The Dietary Guidelines for Americans recommend that adults consume 22.4–33.6 trusted Source 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.
Heart health

Potassium can help regulate blood pressure, and this may decrease the risk of hypertension and cardiovascular disease. The American Heart AssociationTrusted Source (AHA) recommend reducing the intake of added salt in the diet and eating more foods that contain potassium.
According to current guidelinesTrusted Source, 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 studyTrusted Source 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.
There is some evidenceTrusted Source that consuming a type of fiber called beta-glucans may lower blood cholesterol levels. Beta-glucans occur in the cell walls of many types of mushrooms.
The stem of the shiitake mushrooms is a good sourceTrusted Source of beta-glucans. The Mediterranean diet includes a range of plant foods, such as mushrooms. Find out more.
In pregnancy
Many women take folic acid, or folate, supplements during pregnancy to boost fetal health, but mushrooms can also provide folate. A cup of whole, raw mushrooms contains 16.3 microgramsTrusted Source (mcg) of folate. Current guidelines recommend that adults consume 400 mcgTrusted Source of folate each day. What foods should you eat and avoid during pregnancy? Find out here.
Other benefits
Mushrooms are rich in B vitamins, such as:
riboflavin, or B-2
folate, or B-9
thiamine, or B-1
pantothenic acid, or B-5
niacin, or B-3
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.
Nutritional content
