The United Nations Nutrition Report 2020 warns of a likely doubling of hungry people as a result of the COVID-19 crisis. Their number would increase from 130 million to 265 million. The first reason for this disaster is containment. In poor countries, nearly half of the 1.6 billion people living in small-scale informal economy jobs risk losing their main source of income. The second reason is the state of health of the hungry. Malnutrition weakens their immune systems and exposes them to co-morbidities such as diabetes and obesity. The nature of the diet is also involved. The diet of poor countries is too rich in cereals to the detriment of fruit and vegetables.
