Ingredient of the Month: Mushrooms for Mental Health

In this article:

Fungi are fabulously known for many health benefits, including reducing the risk of certain cancers. A study from Penn State College of Medicine shows that eating any kind of edible mushroom may also benefit a person’s mental health, in part to certain nutrients that are particularly abundant in mushrooms.

The Penn State researchers collected diet and mental health data from more than 24,000 U.S. adults for an eleven year span. They found that people who ate mushrooms had lower odds of having depression. They account for this because mushrooms are rich in ergothioneine, an antioxidant that may protect against cell and tissue damage in the body. Studies show that these particular antioxidants may prevent several mental illnesses, such as schizophrenia, bipolar disorder and depression. Oyster mushrooms contain the highest levels of ergothioneine.

“Mushrooms are the highest dietary source of the amino acid ergothioneine, an anti-inflammatory which cannot be synthesized by humans,” said lead researcher Djibril Ba, who recently graduated from the epidemiology doctoral program at the College of Medicine. “Having high levels of this may lower the risk of oxidative stress, which could also reduce the symptoms of depression.”

The most commonly eaten mushroom, the white button, contains potassium, which is believed to reduce anxiety. Other more gourmet species, such as Lion’s Mane (Hericium erinaceus), may prevent depression by stimulating the expression of nerve growth factor synthesis, which helps certain critical nerves survive, which could prevent depression. Mushrooms also include important nutrients for immune support, including vitamins D, C, B’s, selenium, iron, copper and zinc.
