In this paper we present the first global assessments of COVID-19's impacts on food systems and their actors, focusing specifically on the food security and nutritional status of those affected in low and middle-income countries. The review confirms the magnitude and the severity of an unprecedented crisis that has spread worldwide and has spared only a few. The analysis shows that the dimension of food security that has been most affected is accessibility, with reasonably solid evidence suggesting that both financial and physical access to food have been disrupted. In contrast, there is no clear evidence that the availability of food has been affected. Overall, data suggests that food systems resisted and adapted to the disruption of the pandemic. This resilience came, however, at great costs, with the majority of the systems' actors having to cope with severe disruptions in their activities. In contrast, grocery stores and supermarkets made billions of dollars in profits in 2020.
