Shiitake also aids digestion thanks to its fiber content and contains anti-inflammatory and neuroprotective compounds that help protect the liver and improve cognitive function. It can be enjoyed fresh, dried, or as an extract, and its preparation methods are adaptable: it can be sautéed, boiled, or eaten raw in salads.
