Epidemiology of malnutrition
There were 685.6 million malnourished people in the world in 2024, a decrease of 112.7 million since 2005, despite the fact that the world already produces enough food to feed everyone (8 billion people) and could feed more than that (12 billion people).
Reducing malnutrition is key part of Sustainable Development Goal 2, "Zero hunger", with a malnutrition target alongside reducing under nutrition and stunted child growth. Because of the Sustainable Development Goals, various UN agencies are responsible for measuring and coordinating action to reduce malnutrition. According to the World Food Programme, 135 million suffer from acute hunger, largely due to manmade conflicts, climate changes, and economic downturns. COVID-19 could double the number of people at risk of suffering acute hunger by the end of 2020.
