Nutritional value of Stropharia rugosoannulata

Stropharia rugosoannulata has high nutritional value and medicinal properties. It contains a high amount of protein, carbohydrate, fiber, and minerals, with low content of fat and sodium/potassium ratio.

The amount of protein and micronutrient minerals is higher in this mushroom than in button mushrooms, shiitake, and oyster mushrooms.

They are also rich in polysaccharides, triterpenoids, and reducing sugars, which add great medicinal value to this mushroom (2).

Health benefits

1. Rich in nutrients

Stropharia rugosoannulata has high carbohydrates, proteins, fibers, and minerals with low content of fat and sodium/potassium ratio.  Thus this mushroom is suitable for people with a low-fat healthy diet (3).

2. Antioxidant properties

Polysaccharides found in Stropharia rugosoannulata mushrooms act as potent natural antioxidants that remove harmful radicals from the body. Thus the intake of this mushroom protects the body from various diseases (4).

3. Keep bone healthy

The osteoclast is a large bone cell that breaks down or dissolves the bone. The abnormal acceleration of osteoclast may cause osteoporosis, however, Stropharia rugosoannulata contain sterols that suppress osteoclast formation and strengthen the bones (5).

4. Antifungal properties

Systemic candidiasis is a serious Candida infection that is caused by an immune deficiency and affects many organs.   However, Stropharia rugosoannulata exerts antifungal actions against Candida albicans and prevents infections. 

5. Antibacterial properties

Srophoria rugsoannulata contains biologically active substances that fight against different bacteria and prevent various infections. It inhibits bacteria like Escherichia coli, Streptococcus pneumonia, Pseudomonas aeruginosa, Salmonella typhimurium, and Klebsiella pneumonia.

6. Treat brain disease

The cell endoplasmic reticulum stress can cause the death of normal brain cells and further cause degenerative diseases like Alzheimer’s disease. 

The sterols found in Srophoria rugsoannulata protect the brain cells by easing the stress thus treating brain disease (6).

7. Ease cancer

A protein known as lectin in Srophoria rugosoannulata mushroom inhibits the growth of cancer cells and is effective against HIV infection. Thus, this mushroom may develop into a cancer therapy agent (7).

8. Lower cholesterol level

Stropharia rugosoannulata contain a polysaccharide that decreases the bad cholesterol and increases the good cholesterol level in the blood (8).

9. Treat diabetes

Polysaccharides from Stropharia rugosoannulata decrease the plasma glucose level in the blood. It corrects the liver function by promoting insulin synthesis thereby reducing the blood glucose level. Thus, intake of this mushroom manages diabetes (9).

Side effects

Wine cap mushroom has no side effects in moderate amounts but the person who has any mushroom allergy should avoid it. Moreover, it contains hallucinogenic compounds that may cause visual illusions, euphoria, and dizziness. Thus it is best not to eat a high amount for a longer time to avoid problems (10).
