Agaricus bisporus (English: Portobello, Portobello mushroom) is a fungus and the type species of the genus Agaricus. It is native to grasslands in North America and Europe. The fungus grows in the fields and grassy areas. The fungus produces the fruit body that bears spores above ground in late spring to autumn. The fruit body has a large grey-brown cap which on occasion can reach 5–10 centimeters (2–4 inches) in diameter. The tube is facing downward from the underside of the cap. The gills are pink and red-brown initially which turns to dark brown. The stem is white which is bruised to brown in color, up to 6 cm (2 1/3 inch) high, 1-2 cm wide and 1.5-2.5 cm thick.

The scientific name of this mushroom is derived from the Greek word “Aquarius” which means growing in the fields. Portabello Mushroom should not be confused with dangerous and harmful mushroom named Destroying Angel. They could be differentiated by the color of gills and the base of mushrooms.  The gills of Killer mushrooms are snow-white but Portabello mushrooms are pink or brown. The base of the poisonous mushroom has volva or cup whereas the Portabello mushroom does not have.

Health Benefits of Portobello mushroom

Portobello mushroom contains enough proteins, minerals, nutrients which is essential to maintain good health. It contains low calories which makes them suitable for diet. The selenium enhances the body to produce antioxidants. The high amount of niacin helps to reduce Alzheimer’s disease. It contains a rich amount of water which helps to revitalize the body. Portobello mushroom contains more potassium than a banana. An intake of Portobello mushrooms helps to balance the overall health by preventing various health ailments.

1. Prevent Neurodegenerative diseases

The copper therapy showed effective results in preventing Parkinson’s and Alzheimer’s disease. The high amount of copper could be harmful leading to copper posing and impairment of brain functions. The experts say that tight regulated homeostatic mechanisms are required to copper to maintain the required supply in the body. Research shows that the deficiency of copper increases the chances of impaired brain function and cognitive decline.

2. Proper growth

The low presence of copper leads to problems in growth and poor development in children. It also leads to the health ailments such as muscle and joint pain, fatigue, and poor function of the brain. Copper is essential for oxygenation from RBC. Due to the deficiency in copper, the tissues, organs, and cells do not receive an adequate amount of oxygen. The studies show that the low amount of copper in the body slows down the growth reduce weight as well as the height and also slows down metabolic activity.

3. Antioxidant action

Selenium counteracts the aging process and enhances the immune system by lowering the free radical damages. Along with Vitamin E, it provides a synergistic effect that enhances the body to combat oxidative stress and prevent colon and prostate cancer. Selenium eliminates the fat in the cell membranes. It is required to combat the oxidative degradation of cells and prevent the mutation of DNA cells that causes diseases.

4. Cures pellagra

The deficiency of Vitamin B3 is the cause of pellagra. Its symptoms are digestive problems, irritation, skin inflammation, and weak muscles. People with low levels of Vitamin B may experience the problems of converting amino acids and protein metabolism. One can die if the Vitamin B3 levels are not restored.

Malnutrition and chronic alcoholism is the cause of Nicotinic acid deficiency. So niacin is provided to people with malnutrition, irritability, nervousness, insomnia, and loss of consciousness.

Pellagra could be treated with nicotinamide which is a type of Vitamin B3 having the same function as niacin but differs in side effects and absorption.

5. Maintains energy levels

Vitamin B2 is essential to convert food into energy and maintain proper nerve, brain, hormone, and digestive function. Without enough riboflavin, the body won’t be able to digest the molecules that are found in fat, carbohydrate, and protein foods and use them as fuel.

Riboflavin helps to convert proteins into fats, carbohydrates, and amino acids in the form of glucose. It also regulates thyroid activity as well as adrenal function. The deficiency of riboflavin results in thyroid disease. It also soothes the nervous system, reduces chronic stress, and regulates hormones that control energy, appetite, temperature, and mood.

6. Cardiovascular function

Vitamin B5 is required in order to synthesize cholesterol. It influences cholesterol and heart health. It assists to create RBC that transports oxygen throughout the body. It upgrades the hemoglobin levels. It allows Vitamin B2 to perform its function which helps to prevent anemia. Vitamin B2 helps to transport oxygen to the cells and mobilizes iron. The deficiency of Vitamin B2 results in shortness of breath, fatigue, inability to exercise, and others.

7. Detoxify body

Kidneys eliminate the organic molecules found in excess from the blood. Phosphorus is vital for kidney function and detoxifies the body by removing toxins and waste. The kidney depends upon phosphorus, magnesium, and potassium to balance the level of sodium, uric acid, fat, and water within the body.

8. Cures anemia

Vitamin B6 is essential for the creation of hemoglobin in the blood that is transported by RBC in order to bring oxygen to the cells. Anemia is the cause of low red blood cells which have the symptoms such as aches, fatigue, pain, and others. The studies have shown that enough intake of Vitamin B6 can help to reduce the symptoms of anemia and also prevent it.

9. Healthy heart

Potassium acts as an electrolyte and assists to control blood pressure, heartbeat, and circulation. The presence of high sodium and low potassium leads to hypertension, high blood pressure, and cardiovascular disease.

Along with magnesium and calcium, potassium prevents the build-up in the cells which leads to blood pressure and results in narrowed arteries, heart palpitations, poor circulation, and scarring. The low amount of potassium leads to chest pains, irregular heartbeats, and cardiac arrest.

10. Digestive health

Potassium maintains the balance between fluid, water, and sodium levels in the digestive tract. The low presence of potassium is the cause of constipation, bloating, and abdominal pain due to the buildup of fluids and imbalance in minerals. It also balances the acid in the stomach, heals the gut, and maintains optimal pH level. It eliminates harmful bacteria and keeps healthy bacteria.
