Shiitake mushrooms have one of the highest amounts of natural copper, a mineral that supports healthy blood vessels, bones, and immune support. In fact, 1/2 cup of shiitake mushrooms give you 72 percent of your daily recommended intake (DRI) of this mineral. The mushrooms are also a rich source of selenium, providing 33 percent of your DRI.

Here are additional health benefits for shiitake mushrooms:

Improve heart health.

Shiitake mushrooms contain eritadenine, a compound known to reduce cholesterol levels in the blood. They also contain beta-glucans that reduce inflammation and help prevent the intestines from absorbing cholesterol.

Support immune health.

Shiitake are rich in polysaccharides like lentinans and other beta-glucans. These compounds protect against cell damage, help your immune system, and boost white blood cell production for fighting off microbes. Polysaccharides also have anti-inflammatory properties.
