Researchers highlight mushrooms that may help slow the ageing process
Scientists are increasingly focused on ergothioneine, an antioxidant compound found in mushrooms, particularly in button mushrooms, oyster mushrooms and shiitake. Studies suggest it may support cell protection and healthy ageing.
Mushrooms, often seen as a simple addition to a meal, have increasingly drawn scientific attention in recent years. Researchers point to the nutrients and bioactive compounds they contain, which are being studied in connection with the body's ageing processes.
The antioxidant ergothioneine
Particular attention has gone to ergothioneine, a naturally occurring compound with antioxidant properties found in various edible mushrooms. In the human body, a specific transporter enables this substance to reach cells. Researchers note that ergothioneine could play a role in protecting cells and supporting brain function, since oxidative stress and chronic inflammation are linked to ageing and age-related health problems. A review published in 2025, which compiled 19 studies, examined ergothioneine's possible antioxidant, anti-inflammatory and nervous-system-protecting properties.
Three highlighted mushroom types
Among mushrooms that are easy to add to a daily diet, button mushrooms, oyster mushrooms and shiitake are specifically noted. Button mushrooms can be used in soups, sauces, omelettes and salads, and are widely available in almost any grocery store. Oyster mushrooms work well in stews and vegetable dishes, while shiitake are especially common in Asian cuisine, often used in soups and rice dishes.
Possible effects on the brain and heart
Researchers have also examined whether eating mushrooms could be linked to functions such as memory and information-processing speed, looking not only at ergothioneine but also at glutathione and vitamin D as possible protective factors for the nervous system. Other reviews point to a possible link between mushroom consumption and cardiovascular health indicators, as well as a lower overall mortality risk found in some analyses.
Mushrooms also contain fibre, vitamins, minerals and protein, making them a valuable part of a balanced diet. Experts note that only modest, regular portions are needed, added alongside vegetables, whole grains, legumes and fish.
