Oyster mushrooms are low in calories and fat
Oyster mushrooms, or Pleurotus ostreatus, are a group of edible gilled mushrooms named for their shell-like appearance and resemblance to oysters. They are one of the most cultivated and consumed mushrooms worldwide, valued for their soft texture, mild nutty flavour, and distinct health benefits.
In addition to being low in calories and fat, oyster mushrooms are rich in dietary fibre, which helps to keep you satisfied for longer. They are also a good source of protein, with almost 3 grams of protein per cup. Oyster mushrooms are high in several vitamins, including niacin, riboflavin, pantothenic acid, and folic acid, as well as minerals like potassium, magnesium, calcium, phosphorus, copper, iron, and zinc.
Oyster mushrooms also contain bioactive compounds, such as ergothioneine, an amino acid with potent antioxidant properties. These compounds may contribute to oyster mushrooms' potential health benefits, including their ability to reduce inflammation, lower cholesterol, and protect against cellular damage caused by free radicals.

They are high in vitamins and minerals
Oyster mushrooms are neither plant nor animal, but a type of fungus. They are a good source of vitamins and minerals, which are essential for human health. They are particularly high in vitamin B3, which is crucial for assisting the growth and function of organs, as well as the breakdown of lipids, carbohydrates, and proteins in food. Vitamin B3 is also a precursor to antioxidants, which protect the body from cellular damage caused by free radicals.
Oyster mushrooms are also a good source of vitamin B, which helps the digestive system and red blood cells to function optimally. They contain folic acid, a B vitamin that promotes good sleep, memory retention, and may aid in mood regulation. Additionally, oyster mushrooms are high in phosphorus, magnesium, calcium, salt, iron, and zinc, which are all necessary for robust immunity and the prevention of anemia.
Oyster mushrooms also contain vitamin D, which is important for bone health and the absorption of calcium. They are a good source of potassium, which is essential for maintaining healthy blood pressure and heart function. The copper content in oyster mushrooms is important for maintaining mental wellness, as it is involved in the production of dopamine and serotonin, which influence mood, focus, and productivity.
Oyster mushrooms are also a good source of dietary fiber, which is beneficial for digestive health and can help lower cholesterol levels. They are low in calories, fat, and sugar, making them a nutritious addition to a balanced diet.

Oyster mushrooms are a good source of antioxidants
Oyster mushrooms, or Pleurotus ostreatus, are a group of edible gilled mushrooms. They are commonly enjoyed in dishes like pasta and stir-fries and are known for their impressive health-promoting properties. Oyster mushrooms are loaded with fiber, vitamins, minerals, and other important nutrients. They are also low in calories, fat, and cholesterol, making them a good choice for people following low-carb and low-fat dietary patterns.
One of the antioxidants found in oyster mushrooms is ergothioneine, an amino acid with potent antioxidant activity. Oyster mushrooms are the main source of ergothioneine, which has been linked to a reduced risk of cancer. In addition, oyster mushrooms contain higher amounts of antioxidants than other types of cultivated mushrooms, which may be why they are used in so many dietary supplements.
Another antioxidant found in oyster mushrooms is pleuran, a polysaccharide that helps protect the body's cells from free radical damage. Oyster mushrooms also contain beta-glucans, which are fibers that make up the cell walls of yeast and fungi. When fermented by bacteria in the gut, beta-glucans produce short-chain fatty acids that can help reduce cholesterol production in the body. This may be one of the reasons why oyster mushrooms are believed to promote heart health by reducing risk factors like high cholesterol and high blood pressure.

They may help reduce cholesterol
Oyster mushrooms are neither plant nor animal. They are a type of fungus and are commonly enjoyed in dishes like pasta and stir-fries. They are known for their impressive health-promoting properties and are a good source of fibre, protein, vitamins, and minerals.
Oyster mushrooms are believed to be a good source of antioxidants, which can help protect your body's cells from damage caused by free radicals. They contain higher amounts of antioxidants than other types of cultivated mushrooms, which is why they are used in many dietary supplements. Oyster mushrooms are also one of the few species known to be carnivorous, as they can kill a species of tiny worms called nematodes to obtain more nitrogen in their diet.
Oyster mushrooms are also believed to be beneficial for heart health. Some research suggests that eating oyster mushrooms may reduce heart disease risk factors like high blood pressure and cholesterol. A 2011 randomised control trial found that eating a soup containing 30 grams of dried oyster mushrooms for 21 days decreased total cholesterol and oxidised LDL (bad) cholesterol levels compared to a placebo. Another study of 89 participants with diabetes found that eating oyster mushrooms for 7 days lowered their cholesterol, in addition to their blood sugar and blood pressure.
Oyster mushrooms contain beta-glucans, which are fibres that make up the cell walls of yeast and fungi. When fermented by bacteria in the gut, beta-glucans produce short-chain fatty acids that can help reduce cholesterol production in the body.

Oyster mushrooms may help regulate blood sugar levels
Oyster mushrooms, or Pleurotus ostreatus, are a type of edible mushroom that are shaped like oysters. They are one of the most popular mushrooms in the world and are commonly enjoyed in dishes like pasta and stir-fries. They are also one of the few species known to be carnivorous.
Oyster mushrooms are a good source of fiber, protein, and a variety of vitamins and minerals. They are also low in calories, fat, and cholesterol, making them a healthy and nutritious food choice. In addition, oyster mushrooms are believed to be a good source of antioxidants, which can help protect the body's cells from damage caused by free radicals.
Some research suggests that eating oyster mushrooms may help regulate blood sugar levels. A study in 22 people with and without type 2 diabetes found that taking powdered P. ostreatus reduced post-meal blood sugar levels. The authors speculated that the mushrooms increased sugar use in body tissues while inhibiting certain blood sugar-increasing proteins. Similarly, a 2007 study in 30 hospitalized people with type 2 diabetes found that eating 150 grams of cooked oyster mushrooms three times a day for 7 days reduced fasting blood sugar levels by about 22%. After 1 week without mushrooms, fasting blood sugar levels increased by about 13%.
Another study of healthy participants found that taking a mixture of powdered mushroom in water for 14 days reduced their fasting blood sugar levels by 6%. Scientists reviewed previous research in 2020 and attributed oyster mushrooms to controlling blood sugar. They suggested that the beta-glucans in oyster mushrooms may be the cause as they help to slow down digestion and absorption. However, more research is needed to confirm these effects.
