Regular Consumption of Vitamin D Boosts Immunity Against COVID-19

Eating food rich in Vitamin D and taking its supplements can reduce the chances of infection and lower the severity of COVID-19 infection, a study has found.
Finding of the new study were made public by scientists from Boston University School of medicine who analysed the blood samples of 235 COVID-19 cases to measure their Vitamin D levels.
The researchers used cutoff point of 30 ng/mL for the definition of vitamin D sufficiency based on the Endocrine Society’s Practice Guidelines on Vitamin D. The guideline defines vitamin D deficiency and insufficiency as a circulating level of 25(OH)D of <20 ng/mL and 20–29 ng/mL respectively
After adjusting for a number of factors, the study confirmed that there is an association between Vitamin D sufficiency and reduction in clinical severity.
174 out of the 235 cases were discovered to be severe while 57 of these severe cases were discovered to have Vitamin D deficiency.
The study also noted that 40+ year old cases with Vitamin D sufficiency had more than 51.5% chances of survival and lower severity compared with other cases having higher levels of 25(OH)D.

According to the author of the study, Dr Michael Holick, “there is a great concern that the combination of an influenza infection and a corona viral infection could substantially increase hospitalizations and deaths due to complications from these viral infection”.
Also, the professor of medicine recently published a report which says there are 54% chances of not contracting COVID-19 if one’s body is Vitamin D sufficient.
He therefore recommended the regular intake of food rich in Vitamin D or its supplement, especially in winter to reduce the risk of being infected and having complications from COVID-19.
Vitamin D facilitates normal immune system function and it’s good for normal growth, development of bones and teeth and resistance against diseases.
Cereals, sardine, mackerel, salmon, almond, green leafy vegetables, dairy products, orange juice, beef liver, cheese, egg yolks and oat meals are rich in Vitamin D.
