Reviewed by Dr. Richard Fox, MD – Oyster mushrooms (Bone pleura) are edible fungi that have a name that matches their appearance. They grow in forests around the world and are known for their mellow appearance, pleasant taste, and potential health benefits.
As is the case with a range of other fungi, including Cordyceps As lion knows, there is interest in the potential health benefits of oyster mushrooms. These fungi are nutrient-rich, rich in antioxidants, and may have the ability to prevent or treat chronic diseases.
Oyster mushrooms have thick white flesh. Mild flavor and licorice-like aroma. They generally grow on dead or dying hardwood trees such as beech and oak, but can also be found on fallen branches and trunks. In recent years, they have become a hot commodity among foragers.
These mushrooms can be used in many ways, and taste great sautéed with onions and served as a side dish. Oyster mushrooms can also be added to soups, sauces, pasta, and meat dishes.
Like other fungi, oyster mushrooms are a rich source of vitamins, minerals, and antioxidants that may help treat many health signs.
One cup of sliced oyster mushrooms, or 86 grams, contains:

Although you’re unlikely to eat an entire cup of oyster mushrooms in one sitting, they offer a variety of nutrients. They are particularly rich in niacin and riboflavin, B vitamins that are beneficial for healthy cholesterol levels and cell growth and function, respectively.
The nutritional profile of oyster mushrooms offers plenty of potential benefits you can enjoy, including:
Mushrooms are one of the best plant sources of niacin. Research shows that the vitamin can boost levels of high-density lipoprotein (HDL), or “good” cholesterol, and reduce triglyceride levels.
Your body naturally produces cholesterol, and you need it to survive. But too much can be dangerous, especially for your heart.
Eating too many sugary snacks can increase “bad” low-density lipoprotein (LDL) cholesterol that builds up along the walls of your arteries, putting your heart health at risk.
Cholesterol makes it difficult for blood to move through blood vessels and increases the risk of high blood pressure, heart attacks and strokes.
Some animal studies have shown that oyster mushroom supplements can have a significant cholesterol-lowering effect. Mice given oyster mushroom supplements saw a 37% reduction in cholesterol and 45% lower triglycerides.
More work needs to be done to find out if there is a similar effect in humans.
Inflammation is the body’s natural response to an infection or injury, and it’s completely normal. However, sometimes, the immune system does not stop and the inflammation does not go away. This is called chronic inflammation, and is associated with a variety of long-term health conditions.
Test tube studies show that oyster mushrooms may be able to reduce several markers of inflammation, meaning they could have benefits for immune health and inflammatory conditions like rheumatoid arthritis.
Less inflammation may also have benefits for conditions such as heart disease and type 2 diabetes.
Oyster mushrooms also contain nutrients that are beneficial for brain health. In addition to potential anti-inflammatory and cholesterol-lowering benefits (which are good for brain health), the niacin in oyster mushrooms may also contribute to healthy cognitive function.
Research suggests that niacin may help protect against Alzheimer’s disease and cognitive decline in older adults.
Fungi are rich in antioxidants that can provide a number of health-promoting benefits. It helps fight free radicals to maintain cell health and reduce the risk of chronic diseases.
Fiber can help improve digestion and gut health, as well as heart health.
Fiber adds bulk to stool so it passes more easily through your digestive tract. It can also help feed the healthy bacteria in your gut.
Studies have shown that fiber has positive effects on heart health factors such as blood pressure and cholesterol levels.
Oyster mushrooms are mostly considered safe. But there are some things you want to pay attention to.
First, don’t feed yourself. If you are not experienced in foraging for mushrooms, there are simply too many risks involved. Many fungi can easily be mistaken for another, and you may end up with a poisonous mushroom. Leave the fodder to the professionals.
In the same vein, only purchase oyster mushrooms from trusted sources. Some low-priced, non-certified sellers may not have your safety or best interests in mind. Shop from trusted grocers, brands or farmers.
People with mushroom allergies should also avoid oyster mushrooms. They can worsen symptoms such as shortness of breath, inflammation, or other problems you may experience when eating mushrooms.
Oyster mushrooms also contain a small amount of a sugar alcohol called arabitol, which can cause gastrointestinal symptoms in some people.
Purines are another compound found in mushrooms (not just oyster mushrooms) that can cause problems for some people. Purines are broken down into uric acid, which may worsen gout symptoms.
Finally, some people who eat large amounts of mushrooms may experience:
If you plan to supplement with oyster mushrooms, talk to your doctor first and look for reputable products.
If you like mushrooms, oyster mushrooms are definitely worth a try. They are palatable and versatile, and the nutrients within them can benefit your health in many ways.
