About COVID-19

COVID-19 is an infectious disease that has affected more severely older age groups, black and minority ethnic groups, those with other health conditions, and deprived populations. Because of this, it makes health inequalities worse

Currently there is increasing evidence documenting a growing number of people experiencing prolonged symptoms as well. 

Older people, in particular, are more likely to have other long-term conditions, and they are also more likely to have a greater risk of malnourishment, making nutrition and diet a very important aspect of recovery. However, anyone may benefit from improving their diet to help recover from COVID-19.

The UK has defined three COVID-19 disease stages:

  • Acute COVID-19: The first four weeks since symptoms begin (regardless of testing type).
  • Ongoing symptomatic COVID-19: 4–12 weeks after symptoms began.
  • Post COVID-19 syndrome: More than 12 weeks after symptoms began.

This knowledge hub provides information on nutritional care for the recovery from COVID-19.

Nutrition and diet do not substitute vaccination or medically advised COVID-19 treatments.

This knowledge hub is designed to provide information for the general public and does not substitute for medical advice. Dietary advice is complex and difficult to put into practice. Individual responses to dietary changes are highly variable. 

The information in this knowledge hub is not personalised and individuals are advised to seek guidance from a registered dietitian or nutritionist for tailored support.

The research team who designs, edits, reviews and updates the knowledge hub has no conflict of interest to report.

The Nutrition and COVID-19 recovery knowledge hub was originally published on 6 July 2021.
