The human diet is rich with molecules that have been shown to play a role in both the prevention and treatment of viral disease by acting as medicines. Of particular relevance are plant-based foods that possess a complex profile of molecules of various chemical classes such as alkaloids, flavonoids, coumarins, terpenoids and indoles. Laboratory studies revealed multiple mechanisms of action by which these dietary compounds exert their action against functional and genetically diverse viruses. Furthermore, there is a growing body of evidence that poor dietary habits and diet related comorbidities such as obesity, diabetes and cardiovascular disease are responsible for most poor outcomes from COVID-19 across the globe.
