The possible use of dietary components as therapeutic agents is well known and could be a tool against Coronavirus Disease 2019 (COVID-19). This review summarizes the evidence-based literature for immuno-modulation and antiviral activity of different vitamins (A, B, C, D, E), omega-3 fatty acids, selenium, zinc and flavonoids. These substances lessen the vulnerability of risk groups and retard intricate chain of events related to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) invasion. The potential roles of these substances include inhibition of SARS-CoV-2 pathogenesis, inactivation of ACE2 receptors, regulation of innate and adaptive immunity, stimulation of anti-inflammatory responses, regulation of cytotoxic cells activity, antiviral immune induction, retardation of incessant viral replications, suppression of cell signaling pathways and putative inhibition of SARS-CoV-2 major proteases. Moreover, after recovery from COVID-19, nourishing diet is needed to speed up the long-haul symptoms and lingering health issues.
