A Review of the Latest Findings and Practical Recommendations on the Effective Nutrients in the Prevention of Coronavirus

Coronavirus 2019 is an epidemic caused by a group of viruses with symptoms such as respiratory symptoms, fever, sore throat, and fatigue. This article is presented with the aim of practical recommendations in the field of effective nutrients against coronavirus.

In this review article, articles focusing on nutrition, the immune system, viral infections, and coronaviruses were published by searching databases for both articles and manuscripts accepted from 1990 to 2020, and articles without English abstracts were excluded from the review system.

Some nutrients are actively involved in the proper functioning and strengthening of the human immune system against viral infections including dietary protein, omega-3 fatty acids, vitamin A, vitamin D, vitamin E, vitamin B1, vitamin B6, vitamin B12, Vitamin C, iron, zinc and selenium. There have been few studies on the effect of dietary factors on the prevention of COVID-19, but supplementation with these nutrients may be effective in improving the health status of patients with viral infections.

Following a balanced diet and supplementation with appropriate nutrients may play an important role in the prevention, treatment, and management of COVID-19. However, more clinical trials are needed to confirm these findings and provide strong recommendations against the epidemic.
