Researchers said experiments on rodents and humans had found a “number of edible mushrooms” have been shown to contain rare and exotic compounds that are good for the brain.

The fungi contain chemicals that boost nerves in the brains by preventing inflammation and a study of eleven types of mushrooms – some already used for medicinal purposes – found they increased grey matter by raising production of a chemical called NGF (nerve growth factor (NGF).

Mushrooms contain diverse yet exclusive bioactive compounds that are not found in plants. Eating mushroom or mushroom-based extracts might have beneficial effects on human health and improve brain function.
