Abstract
Background: During late 2019 a viral disease due to a novel coronavirus was reported in Wuhan, China, which rapidly developed into an exploding pandemic and poses a severe threat to human health all over the world. Until now (May 2021), there are insufficient treatment options for the management of this global disease and shortage of vaccines. Important aspects that help to defeat coronavirus infection seems to be having a healthy, strong, and resilient immune system. Nutrition and metabolic disorders, such as obesity and diabetes play a crucial role on the community health situation in general and especially during this new pandemic. There seems to be an enormous impact of lifestyle, metabolic disorders, and immune status on coronavirus disease 2019 (COVID-19) severity and recovery. For this reason, it is important to consider the impact of lifestyle and the consumption of well-defined healthy diets during the pandemic.Aims: In this review, we summarise recent findings on the effect of nutrition on COVID-19 susceptibility and disease severity and treatment. Understanding how specific dietary features might help to improve the public health strategies to reduce the rate and severity of COVID-19.
Highlights
The recent outbreak of coronavirus disease 2019 (COVID-19), caused by a new zoonotic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) [1], is a great threat to public health all over the world [2]
The direct consequences of COVID-19 on an individual represents a spectrum of clinical severity with some patients being asymptomatic or having only mild upper respiratory tract symptoms whilst some subjects have severe pneumonia characterised by fever, cough, dyspnoea, bilateral pulmonary infiltrates and acute respiratory injury requiring
We summarise recent findings regarding the impact of nutrition on the variation in COVID-19 disease severity and its potential impact on the control of the disease during the current pandemic
