This research article discussed about the global malnutrition crisis that is caused by the COVID-19 pandemic. As these crises will damage the nutritional status of the vulnerable groups through multiple mechanisms and poverty. Also, malnutrition will increase due to healthcare failures, as it already strained healthcare systems which are forced to divert resources from a range of nutritionally important functions — including antenatal care, immunization, micronutrient supplementation, and prevention and treatment of childhood diarrhoea, infections, and acute malnutrition — toward combating COVID-19. The COVID-19 economic crisis will also affect diets primarily through declining demand for vegetables, fruits, and animal-sourced foods, which are the main sources of essential micronutrients in diets. Policymakers and researchers alike are operating in a unique state of uncertainty, and those working on nutrition may struggle to get their voices heard in the fog of this war against COVID-19. And it is now more critical than ever that multisectoral nutrition groups advocate and support key actions to protect nutritionally vulnerable groups with many of these actions also contributing to poverty reduction.
