They are rich in antioxidants and may help reduce inflammation
Oyster mushrooms are rich in antioxidants, which are substances that help reduce or prevent cellular damage in the body. They contain higher amounts of antioxidants than other types of cultivated mushrooms, including seven phenolic compounds such as gallic acid, chlorogenic acid, and naringenin, which act as antioxidants. Oyster mushrooms also contain ergothioneine, an amino acid with potent antioxidant activity.
The high antioxidant content of oyster mushrooms may offer several health benefits. Test-tube, rodent, and human studies have shown that oyster mushrooms may help reduce inflammation. For example, a 2007 study in rodents found that treatment with oyster mushroom extract improved antioxidant levels and lowered certain inflammatory markers, including malondialdehyde (MDA). Similarly, a small study in humans published in 2016 found that participants who ingested an oyster mushroom extract for eight weeks showed potential immune-enhancing effects, which could help reduce inflammation in the body.
Oyster mushrooms are also a good source of dietary fiber, which has been associated with better heart health and a reduced risk of certain diseases. They are low in calories, sugar, and fat, and provide a good amount of protein and various vitamins and minerals, making them a nutritious addition to a healthy diet.
In addition to their nutritional benefits, oyster mushrooms are prized for their culinary uses. They have a delicate taste and can be used to enhance the flavor of a wide variety of savory dishes. They are commonly found in Asian cuisine and have also gained popularity in other parts of the world, where they are used in stews, soups, stir-fries, and more.
