From puffballs to truffles, mushrooms can range from everyday fare to a costly delicacy. People can buy them fresh, canned, or dried.

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.
Many types of mushroom are edible, and most provide about the same quantities of the same nutrients per serving, regardless of their shape or size.

|Carbohydrate (g)||3.1, including 1.9 g of sugar||130|
|Vitamin C (mg)||2.0||65–90|
|Vitamin D (mg)||0.2||15|
|Folate (mcg DFE)||16.3||400|

Tips for serving
The Environmental Working Group, which assesses foods for their pesticide contents, placed mushrooms that grow in the U.S. in its 2019 list of the 15 cleanest foods, referring to relatively low traces of pesticides.
However, people should still wash and clean them carefully before using them to remove any soil and grit. If necessary, trim the ends of the stalks. You can use mushrooms whole, sliced, or diced.

- removing the stems of portobello mushrooms, marinating the caps in a mixture of olive oil, onion, garlic, and vinegar for 1 hour, then grilling them for 10 minutes
- adding grilled portobello mushrooms to sandwiches or wraps
To prepare dried mushrooms, leave them in water for several hours until they are soft.
