Vitamin D plays an important role in building a healthy immune system
Confirmation of Vitamin D Correlation in Adult and Elderly Subjects with Corona 19
Recommended daily intake of 4000 IU (100㎍) vitamin D
[디지털투데이 이장혁 기자] In the Corona 19 situation, there is increasing interest in the benefits of vitamin D in the prevention and treatment of diseases.
Since vitamin D plays an important role in building a healthy immune system by inducing the expression of antimicrobial peptides on the surface of immune cells and epithelium, it is known that the body must have a sufficient amount of vitamin D in order for the immune system to function normally.
According to a recent study by a research team from Professor Marcos Pereira of the Federal University of Bahia in Brazil published in the latest issue of “Critical Reviews in Food Science and Nutrition,” an international journal in the field of food. In the case of vitamin D deficiency patients, Corona 19 is worse.
As a result of systematic literature review and meta-analysis to confirm the correlation with vitamin D in adult and elderly subjects with COVID-19, vitamin D deficiency was not directly related to the possibility of COVID-19 infection.
However, it was found that the proportion of patients with vitamin D deficiency was 64% more in the severe corona19 group than in the mild patient group.
In addition, it was confirmed that the hospitalization rate of patients with Corona 19 deficient in vitamin D increased by 81% and the mortality rate by 82% compared to patients without vitamin D deficiency.
The research team revealed that there is a close correlation between vitamin D deficiency and the severity of Corona 19 disease.
Recently, 100 experts, including scientists and doctors from around the world, made a joint statement on the need for vitamin D intake in the journal’Geriatrie et Psychologie Neuropsychiatrie du Vieillissement’. <비타민D 보충제와 코로나 19: 전문가 합의 및 지침>Announced.
Vitamin D deficiency (serum 25-OH vitamin D concentration of 50 nmol/L (20 ng/mL) or less) is associated with severe corona19.
Experts recommend sufficient efforts to achieve serum 25-OH vitamin D concentrations of 75 nmol/L (30ng/mL) or higher in order to reduce the risk of COVID-19, and recommend daily intake of 4000 IU (100㎍) of vitamin D. have.
Vitamin D is supplied from sunlight in addition to food. The time for vitamin synthesis without causing erythema on the skin suggested by experts is 20 to 40 minutes a day.
However, it is difficult to expect a supply of vitamin D from the actual sunlight during a difficult time to go out.
It is necessary to get vitamin D through food or supplements. Foods that naturally contain vitamin D include blue-green fish, fish liver oil, and egg yolk.
Foods fortified with vitamin D, such as soy milk and yogurt, can also be a major source.
Soymilk is a food made from soybeans, and according to a review study published in The Journal of Nutritional Biochemistry, an SCI-level scientific journal, soybeans are rich in genistein, which inhibits the infection and proliferation of viruses. . In addition, soybeans contain soybean saponin, which is known to be good for improving immunity.
