Mushroom as a Dietary Supplement Pleurotus ostreatus, the oyster mushroom or oyster fungus or Dhingri in India, is a common edible mushroom. It has the bittersweet aroma of benzaldehyde. The oyster mushroom is one of the most suitable fungal organism for producing protein rich food from various agrowastes without composting. Medicinal and nutritional value of oyster mushroom: Oyster mushrooms are 100% vegetarian and the nutritive value of oyster mushroom is as good as other edible mushrooms like white button mushroom, shiitake, or paddy straw mushroom. They are rich in vitamin - C and B complex. Why Eat Mushrooms? No cholesterol and low fat with ergosterol and polyunsaturated fatty acids: Good for Heart. Low calorific food with no starch, low sugars: Delight of Diabetics. High Fibre, low sodium-high potassium diet: Anti-Hypertensive. Good source of vitamin B-complex and Vit C; only vegetable source of Vit D. Rich in minerals like copper (cardio-protective) & Selenium (anti-cancer). Anticancer, Anti-HIV, Anti-viral, Anti-histaminic, Hypo-cholesterolemic,Hepato-& Nephro-protective, Anti-oxident, stamina enhancer, etc.1 Only vegetable source of Vitamin D- Vitamin D is critical for bone and mineral metabolism. Because the vitamin D receptor is expressed on immune cells such as B cells, T cells, and antigen-presenting cells, and because these cells can synthesize the active vitamin D metabolite, vitamin D also has the potential to modulate innate and adaptive immune responses. Vitamin D supplements may increase the levels of T regulatory cells in healthy individuals and patients with autoimmune diseases; vitamin D supplements may also increase T regulatory cell activity.2 In a meta-analysis of randomized clinical trials, vitamin D supplementation was shown to protect against acute respiratory tract infection. 3 High levels of vitamin D may cause hypercalcemia and nephrocalcinosis.4
Patients hospitalized with COVID-19 who has sufficient levels of vitamin D show significant reductions in severe outcomes and a lower risk of death compared with insufficient levels, new research shows. "This study provides direct evidence that vitamin D sufficiency can reduce the complications including the cytokine storm and ultimately death from COVID-19," said senior author Michael F. Holick, MD, PhD, of Boston University School of Medicine, Massachusetts, in a press statement from his institution. The research examines hospitalized patients with severe COVID-19 in Iran, and Holick worked with lead researcher Zhila Maghbooli, MD, of the Tehran University of Medical Sciences, and colleagues, on the study, which was published in PLoS One.5 Conclusion- As there has been increase in number of covid-19 patients there has been increase in requirements for the nutritional food. Mushroom as an only source of vitamin D, it can be consumed as a daily nutritional food in our diet. As is low calorific food with no starch, low sugars it can be consumed with the patients suffering from Diabetes. Also it has traces of vitamin B-complex and Vit C it can be given as a nutritional food to Covid-19 patients. Overall it acts as a rich source of vitamins which can consumed as a household remedy.
