A recent article published in Nutrients stated that COVID-19 negatively impacts the nutritional status of individuals. Over the past few months, clinical nutrition professional organizations across the globe have published nutritional support recommendations for health care professionals. 

The present review identified 15 publications from electronic databases and websites of clinical nutrition professional organizations, up to 19th June 2020.
