The relationship between nutrition and COVID-19

Guest editor(s)
Dr Mauro Lombardo,


The COVID-19 pandemic has had a huge impact on health care, and social and economic repercussions, worldwide in recent months. A huge number of studies have been published in the last two years trying to establish a connection between diets, supplements, micronutrients and prevention/therapy of COVID-19. Despite the relevance of nutritional research related to COVID-19, the existing evidence is remarkably poor. Therefore, increasing the evidence on the potential key contribution of nutritional status and nutritional care to COVID-19 is an  important priority.  


The special issue aims to assess whether nutritional status could improve the body's ability to prevent and heal COVID-19 infection. In addition, manuscripts assessing whether changes in dietary intake and physical activity due to COVID-19 could influence nutritional status will be accepted.  


Although thousands of papers have been published evaluating possible correlations between nutrition and COVID-19, there is a need for a more objective and less emergent investigation of what dietary interventions might be useful in preventing or treating COVID-19.  


List of topic areas 

  • Malnutrition risk
  • Micronutrient status

  • Special patient groups: chronic and liver diseases, cancer, diabetes, the elderly etc.
