Health benefits of Shimeji mushrooms

Shimeji mushroom is industrialized culinary, medicinal mushroom known for its high therapeutic value with significant antioxidant, anti-inflammatory, immunomodulatory, anti-tumor, anti-atherosclerotic, antihypertensive, anti-aging and cholesterol-lowering properties (3).

1. Nutrients rich Shimeji mushroom

This mushroom contains a high amount of nutrients mainly to polysaccharides as the active compounds. Other nutrients like protein, fiber, energy and low-fat content which is beneficial for those having noncommunicable diseases. 

It also contains potassium phosphorus followed by magnesium, zinc, and copper. 

Other than this it is also a rich source of ergosterol steroids, provitamin D2, riboflavin, biotin, and niacin.

2. Shimeji mushrooms are low in cholesterol

Shimeji mushrooms contain dietary fiber which enhances the fecal excretion of bile acids and lowered insulin response. Therefore, mushroom powders not only reduce serum total cholesterol concentrations but also atherosclerotic lesion formation than other mushrooms such as Eringi and Maitake mushroom (4). 

3. Prevents parasitic infection

Shimeji mushrooms contain protease enzymes which possess a nematicidal effect on Panagrellus redivivus and bovine infective larvae which affect plants, animals and humans and protect from parasitic diseases (5).

4. Shimeji mushroom is a potential natural anticancer agent

Shimeji mushrooms are rich in glycoprotein (HM-3A), marmorin, beta-(1-3)-glucan,  hypsiziprenol, and hypsin. These compounds inhibit the proliferation of various cancer cells such as leukemia, hepatoma, breast, sarcoma, lung carcinoma cells (6). Thus, Shimeji mushrooms caps are a potential good natural source of anticancer agents (7).

5. Antifungal Shimeji mushrooms because of Hypsin compound

Hypsin (ribosome-inactivating protein) present in mushroom possess antifungal activity against various pathogenic fungi such as Physalospora piricola, Fusarium oxysporum, Mycospharella arachidicola and Botrytis cinerea (8).

6. Shimeji mushrooms in the treatment of Hypertension

Shimeji mushrooms contain angiotensin I-converting enzyme (ACE) inhibitor which is oligopeptide that may be helpful in lowering blood pressure and reduce the risk of stroke in persons having hypertension (9).

7. Anti-inflammatory properties of Shimeji mushrooms

Shimeji mushrooms are rich in polysaccharides, phenolic compounds, and flavonoids. Thus inhibits inflammatory cytokines and oxidative stress and protect from lung failure.  Therefore, Shimeji mushroom may be useful of amending inflammatory responses and act as a natural drug against lung failure in the future (10).

8. Anti-bacterial Shimeji mushrooms

Shimeji mushroom is a rich source of phenolic and flavonoid content which is beneficial for protect against various bacteria such as Serratia marcescens, Escherichia coli Bacillus subtilis and Staphylococcus aureus (11,12).

9. Shimeji mushrooms are rich in antioxidants

Phenol, steroids, flavonoids and ascorbic acid found in the mushroom are biologically active components that prevent oxidative stress-mediated disease through radical scavenging activity.

10. Management of diabetes and weight

This mushroom contains hypsiziprenol, hypsin, polysaccharides and dietary polyphenols, such as resveratrol. It helps in reduction of fat deposition without affecting body weight loss by activating obesity-related gene which is responsible for oxidation and lipolysis. Furthermore, intake of this mushroom lower the fasting plasma insulin and plasma glucose, modulate glycemic index and increase the antioxidant contents thus regulate both obesity and insulin resistance.

Side effects of Shimeji mushrooms

Shimeji mushrooms have no side effect because practically No clinical study has reported so far. However, Shimeji mushroom deteriorates rapidly after harvest due to water loss, browning, softening, stipe elongation and hollowing, pileus expansion, and splitting, and the appearance of unsightly aerial hyphae on the pile surface during refrigeration, all of which greatly reduce consumer acceptability.
