Mushrooms are a good source of B vitamins, including Riboflavin, Niacin, and Pantothenic acid, which help to provide energy by breaking down proteins, fats and carbohydrates. B vitamins also play an important role in the nervous system.

Mushrooms are the leading source of the essential antioxidant Selenium in the produce aisle. Antioxidants, like selenium, protect body cells from damage that might lead to chronic diseases. They help to strengthen the immune system, as well. In addition, mushrooms provide ergothioneine, a naturally occurring antioxidant that may help protect the body’s cells.

When building your plate to maximize vitamin D, consider mushrooms – they’re the only source of vitamin D in the produce aisle and one of the few non-fortified food sources.

Mushrooms are hearty and filling.   Increasing intake of low-energy-density foods (meaning few calories given the volume of food), specifically mushrooms, in place of high-energy-density foods, like lean ground beef, can be an effective method for reducing daily energy and fat intake while still feeling full and satiated after the meal.
