It basically contains protein ranging from 19%-35% which is higher as compared to convenience food crops like rice, corn and wheat. The quality of protein is also high as it contains all the essential amino acids required by the body. Carbohydrate content present in mushrooms is about 50%-65% on a dry matter basis. Water-soluble carbohydrate has pharmacological effects in the body. The fat content in mushroom ranges from 2%-6% which includes the essential fatty acids [5].

Vitamins: Mushrooms are wealthy supply of B-complex nutrients. Mushrooms are wealthy with B-complicated vitamins like thiamine, cyanocobalamine, riboflavin, pyridoxine, niacin and pantothenic acid. Those vitamins act as co-enzyme for facilitating the numerous metabolic reactions taking place inside the frame. Mushrooms also have better content of diet D. The ascorbic acid is also found in mushrooms in small amounts. Provitamin A and nutrition E also are found in mushrooms.

Minerals: Mushrooms have principal minerals like ok, P, Na, Ca, Mg etc. which constitute approximately 50%-76% of the whole ash content of the mushrooms. Wild mushrooms have greater mineral content than the cultivated ones. Zinc, selenium, copper, iron etc. also found in mushrooms. Selenium and zinc have antioxidant potential and might assist in preventing oxidative damage. Zinc plays the maximum important position for the frame's protecting (immune) gadget to nicely work and it also help in mobile department, mobile development and wound restoration. Copper enables in the manufacturing of erythrocytes which can be used to supply oxygen everywhere in the frame. Selenium works as an antioxidant to guard our body cells from harm that might likely result in coronary coronary heart ailment and also prevents ageing. The potassium to sodium ratio in mushrooms is higher i.e., 110:1, that is helpful in improving blood flow and additionally prevents high blood strain [6].

Biologically active compounds: Mushroom contain aromatase enzymes which are important for production of estrogen in the body. Various alkaloids like cordycepin, lectins, levostatin etc. are beneficial for various functions in the body. The mushroom sterol (ergosterol) performs the same function as cholesterol. Antioxidants present in mushrooms include a compound called ergothioneine, which have protective functions against CVDs, chronic inflammations and neurodegenerative diseases.

Pharmacological properties of mushrooms

Anticancer properties of mushrooms: The bioactive metabolites play a crucial function in anticancer homes of mushrooms. One of the mushrooms named tiger milk mushrooms incorporate high stage of beta-glucans which play an essential characteristic in boosting the immune system of the body and it also prevents the cancer forming mobile and their spreading. Mushrooms comprise unique bioactive compounds such as polysaccharides, polysaccharide-protein edifices and β-glucan, which show off mitigating, most cancers prevention agent, antagonistic to proliferative and immuno-adjusting influences. In historic times the powder of reishi mushroom has been applied to treatment most cancers in China. It was used for appearing chemotherapy in most cancers patients and that they were found to be useful to lower tumor and malignant cellular boom in patients with breast and prostate cancers. Numerous RCT investigations exposed the position of Polysaccharide K (PSK) from mushrooms to standard chemotherapy extended the patience of patients after recuperation gastric malignancy resection over chemotherapy alone. This confirms the potential of polysaccharides to cause apoptosis and result in various type of cellular demise facilitated by means of immunological components present inside the mushrooms. The cancer stopping movement of mushrooms can be correlated to the phenolic components together with flavones, flavonoids and so forth. Of mushrooms that have anticancer capability [7].

Antioxidant properties: Oxidation of any compound inside the human cells outcomes in formations of unfastened radicals.
