What Is Oyster Mushroom?

Oyster mushrooms are a type of edible fungi. They feed on dead and decaying material like wood, and their cap can grow between two to 10 inches. They are available in different colors, ranging from white to dark brown, and have a mild taste and odor similar to anise.

Health Benefits Of Oyster Mushrooms

1. Loaded With Antioxidants

Oyster mushrooms are great sources of antioxidant phenolic compounds like variegatic, ergothioneine, and gallic acids (2), (3), (4), (5). These antioxidants neutralize free radicals, inhibit oxidative damage, and may help reduce LDL cholesterol (bad cholesterol) (6), (7).

2. Improve Heart Health

Consuming oyster mushrooms may reduce the risk of cardiovascular diseases. They contain beta-glucans, which have antihypertensive effects and can lower LDL-cholesterol levels (8). Moreover, the dietary fiber in oyster mushrooms may prevent hypercholesterolemia (high cholesterol level) (9).

A review published in the International Journal of Molecular Sciences suggests that polysaccharides in mushrooms reduce the risk of cardiovascular disease. Consuming oyster mushrooms can reduce the total cholesterol and triglyceride levels (10), (11). However, more studies are needed to understand this benefit on humans.

3. Lower Blood Sugar Levels

The dietary fiber in P. ostreatus prevents insulin resistance (12). A study conducted by the University of Jayewardenepura, Sri Lanka, found that freeze-dried and powdered forms of P. ostreatus at a dose of 50 mg/kg/body weight reduced blood glucose concentrations (13).

Another study showed that oyster mushrooms significantly reduced blood glucose levels in people with diabetes. The mushrooms can increase glycemic status and help manage type 2 diabetes (14), (15).

4. Support Immune Function

Golden oyster mushrooms may contain other immune regulative compounds like vitamin D2 and support immune health (16). A study observed that consuming oyster mushrooms for eight weeks could enhance natural killer (NK) cells (a part of the immune system) and protect against several diseases (17).

The imunoglucan in oyster mushrooms can prevent recurrent respiratory tract infections (RRTIs) (18). Oyster mushrooms are also effective against Herpes Simplex Virus type-1 (HSV-1) (19).

5. May Reduce Cancer Risk

The protein extracts of oyster mushrooms have anti-cancer effects and may inhibit the proliferation of breast and colon cancer cells (20), (21). A study conducted by the Methodist Research Institute, USA, found an inverse relationship between oyster mushroom intake and cancer risk (22).

Water extracts of edible mushrooms like oysters have the potential to suppress cancer cell proliferation, especially breast cancer cells (23). However, more studies are needed to understand the anti-cancer effect of oyster mushrooms in humans.

6. Have Anti-inflammatory Properties

Animal studies showed that oyster mushrooms possess anti-inflammatory properties and helped reduce inflammatory conditions (24), (25).

Another study concluded that biotechnologically produced oyster mushroom supplementation improved gut health in obese Zucker rats (26). However, limited studies are available to prove this claim.

If you have never tried oyster mushrooms before, here are a few ways to incorporate them into your diet.

Nutritionist Maryam Azhar says, “Oyster mushrooms must be saut√©ed or steamed for just 5-6 minutes to get maximum benefits. If mushrooms are cooked on high heat or fried, they can lose their nutritional content.”

Ensure you do not overcook the mushrooms and always eat fresh ones. However, you can store them for a few days before eating. Here are a few tips for storing them properly.

How To Store Oyster Mushrooms

Place the mushrooms in a loosely closed plastic bag in the refrigerator to keep them fresh for 5 to 7 days. Freeze them for 1 to 3 minutes and drain thoroughly. Seal in airtight bags and place in the freezer. You can store dry oyster mushrooms in the oven at 150°F for an hour and store them for longer periods. However, make sure you do not consume excess oyster mushrooms as it may cause adverse effects.

Possible Side Effects Of Oyster Mushrooms

Oyster mushroom contains ostreolysin, a toxic protein. Animal studies found that this protein may cause respiratory issues and increase arterial blood pressure (27). However, its effects on humans are not known.

Oyster mushrooms may also trigger symtpoms of hypersensitivity pneumonitis, an inflammation of small airways in the lungs and cause fever, joint pain, and chills.

Also, in rare cases, mushrooms may be contaminated with heavy metals. Hence, always get the mushrooms from a trusted source and farms that follow proper agricultural practices.

To Conclude

Oyster mushrooms are the most commonly available edible mushrooms. They are packed with nutrients and antioxidants and have several health benefits. You can add them to your favorite dishes like stir-fries, soups, and pasta. However, excess intake of oyster mushrooms may cause some undesirable side effects and allergic reactions. Hence, limit their intake and consult your doctor in case of any emergency.

Recomiendo una porci√≥n diaria de  bayas  (media taza fresca o congelada, o un cuarto de taza seca) y tres porciones diarias de otras frutas (una fruta de tama√Īo mediano, una fruta cortada en taza, o un cuarto de taza seca).  ¿Por qu√© selecciono las bayas?
