A Concise Review: Nutritional Interventions for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)

Abstract

Wuhan, China reported a novel coronavirus-related sickness in late 2019, which quickly spread into a global epidemic. One crucial factor in combating the coronavirus infection appears to be the presence of a robust, long-lasting, and active immune system. The immune response is affected by several factors, including food. Nutritional insufficiency can cause immune deficits, making infections more likely to cause fatality. Thus, understanding numerous behaviors, particularly dietary habits, is essential to determining their capacity to reduce severe acute respiratory syndrome coronavirus 2 risks and improve prognosis. In this paper, the authors summarize the complex interaction between nutritional status and severe acute respiratory syndrome corona virus 2 infections, as well as the consequences of poor nutrients with regard of the extent to which disease is affected. The literature was compiled by searching a number of reputable scientific databases including Scopus, Science Direct, Springer, Nature, PubMed, Web of Science resources. The accumulating evidence demonstrates that malnutrition impairs the immune system's ability to function, weakening the body's infection resistance. This review emphasizes the significance of nutritional status in the care of coronavirus disease patients as well as demonstrates that functional foods may contribute to better outcomes. Ageing, Obesity, Malnutrition, Undernutrition, Lack of exercise are having a devastating effect on people's health in general and during this coronavirus disease. The severity and prognosis of coronavirus illness seem to be significantly influenced by lifestyle choices, nutritional imbalances, and impaired immune response.
