Nutritional and Health Benefits of Oyster Mushroom Tart

Oyster mushrooms are one of the most common types of edible mushrooms in the world. They taste mild and savory, with a flavor similar to seafood.

Due to its medicinal properties, more people use oyster mushrooms to cook with. Their unique flavor adds to some pretty amazing health benefits.

The many health benefits of oyster mushrooms help the following conditions:

Condition #1: Atherosclerosis

Atherosclerosis hardens or impairs arteries. Oxidative stress, high blood pressure, and high cholesterol all cause atherosclerosis over time.

Research shows that oyster mushrooms help prevent this type of condition. They contain beta-glucans, which keep cholesterol levels under control.

Plus, the ergothioneine content of mushrooms prevents plaque forming in our arteries.

Condition #2: Anemia

Anemia is a condition where our blood doesn’t have enough healthy red blood cells, known as hemoglobin.

Vitamin B2, called riboflavin, helps prevent anemia. Riboflavin produces red blood cells and thus, helps mobilize iron through the body.

You have to replenish the vitamin daily so your body has access to a healthy supply, because it doesn’t store B2. Eating oyster mushrooms is also great for providing it to our body, which is a type of water-soluble vitamin.

Condition #3: Osteoporosis

Therefore, Vitamin D is very important in promoting healthy bones and preventing osteoporosis.
