Study Objective
To evaluate the interrelation between nutrition and the COVID-19 pandemic, including how nutrition may modulate the disease's impact and how the pandemic has altered nutritional behavior globally.
Short Abstract
This systematic review assesses the bidirectional relationship between nutrition and COVID-19. It explores how poor nutrition may increase susceptibility to severe COVID-19 outcomes and how the pandemic itself has affected global food security, nutritional behavior, and dietary habits. The review also highlights the potential benefits of certain diets and nutraceuticals in managing COVID-19 risk and improving outcomes.
