2. Shiitake mushrooms provide fiber.

You also get 3 grams of fiber in that cup of Shiitake mushrooms. Fiber is a type of indigestible carbohydrate found only in plants and mushrooms. It plays a number of roles in the body, supporting heart health, gut health, regularity and healthy blood sugar levels within normal ranges. Men need to eat 38 grams daily, according to the 2015-2020 Dietary Guidelines for Americans, while women need 25 grams, but most people fall short. Eating a cup of mushrooms puts you closer to your daily quota in a tasty way!

3. Shiitake mushrooms are a good source of riboflavin, vitamin B6, niacin, zinc and manganese.

Foods are a “good source” of an essential mineral or vitamin if they provide 10% to 19% of the Daily Value of that nutrient in a serving. Shiitakes give you 15% of your DV for riboflavin, 12% of the DV for B6 and 11% of your niacin.

Zinc is a mineral that supports wound healing and immune health, and you get 13% of your DV from a cup of cooked Shiitakes. You also get 15% of your manganese for the day, which supports blood clotting and other important processes in the body.

4. Shiitake mushrooms are an excellent source of pantothenic acid (vitamin B5) and selenium.

Vitamin B5 is better known as pantothenic acid. While not as well-known as some other vitamins, B5 helps you make blood cells and process food into energy. By providing 52% of the DV for this vitamin, Shiitake mushrooms are an excellent source (meaning they provide at least 20%).

Plus, you get over half of your daily selenium (51%) and copper (65%) from Shiitakes! Selenium is a mineral that is known to have potent antioxidant qualities, while copper helps support energy production, iron metabolism and more.

5. Shiitake mushrooms contain vitamin D.

Vitamin D is a fat-soluble vitamin that your body needs to absorb calcium (for bone health). It also helps healthy cell growth and immune function.* Most of the time, we get this nutrient from animal-based foods (or sunlight), but one of the coolest Shiitake mushrooms health facts is that they also provide vitamin D.

A cup will give you 40.6 international units of vitamin D, in the form of ergocalciferol (D2). When Shiitake mushrooms are exposed to UV light, they can actually increase their vitamin D levels!

6. Shiitake mushrooms support immune health.*

In both China and Japan, Shiitake mushrooms were traditionally used to support the immune system for everything from acute responses to cellular support.(1)* Today, Shiitake fruiting body extract, which is known as lentinan, is researched and used widely. Lentinan supports white blood cells and offers antioxidant support for the immune system.*(2)
