The Superfood Qualities of Mushrooms

The benefits of fungi are still largely unknown—but researchers keep turning up surprising ways they boost human health.

Edible fungi, like shiitake, oyster, and lion’s mane mushrooms, have been linked to boosting immunity and improving treatment results in cases of cancer, high cholesterol, and neurological diseases. Injections of an extract of shiitake mushrooms (Lentinula edodes) may slow the growth of tumors and improve outcomes of chemotherapy.
This story appears in the March 2018 issue of National Geographic magazine.

Mushrooms are everywhere — on forest floors, in gardens, in networks connecting below our feet. The largest organism on Earth is actually a honey mushroom, an underground web that covers more than 3.7 square miles in Oregon’s Blue Mountains.

Yet mushrooms are poorly understood, and the field of medicinal mushrooms is still in its infancy. Fungi used to be overlooked as a low-calorie, low-nutrition food, but in fact many are full of nutrients. According to biochemist and herbalist Martin Powell, many produce compounds that show potential for improving treatment results for those suffering from ailments such as cancer and dementia.

“Fungi are far more mysterious than plants,” says Robert Beelman, director of the Penn State Center for Plant and Mushroom Foods for Health. He led a recent study showing that two common antioxidants in some mushrooms—ergothioneine and glutathione—have the potential to help ward off diseases that come with aging, such as heart disease and Alzheimer’s. Some species are famous for their hallucinogenic properties. Others, like the mushrooms shown here, not only are appreciated by chefs but also show therapeutic value. Perhaps in the future, superfoods won’t be just plants but also fungi.

July 8, 2016 - You probably didn't know mushrooms could be used to construct buildings and cure diseases. Mushrooms are being tested in innovative and imaginative ways to help society. Engineers, medical researchers, and designers are utilizing the natural abilities of various fungi for antibiotics, building materials, water filtration, toxic waste cleanup, pest abatement, textiles, and other purposes.
