Research in context Evidence before this study We conducted a systematic search of the National Library of Medicine for articles on associations between diet and COVID-19 risk. We found that a limited number of studies have evaluated the role of specific food groups in the onset and progression of SARS-CoV-2 infection and COVID-19 symptoms. However, evidence on associations between dietary patterns or indexes, treating diet as a whole, is rare. Generally small studies have indicated that a healthy anti-inflammatory diet is associated with a lower risk of COVID-19 infection. However, there are no prospective data from sufficiently large cohorts to provide robust evidence on the effect of dietary inflammatory potential on the risk of COVID-19 incidence, disease severity, or mortality.
