One billion people in the world were undernourished in 2009, according to a new report.
The 2010 Global Hunger Index shows that child malnutrition is the biggest cause of hunger worldwide, accounting for almost half of those affected.
Countries in sub-Saharan Africa and South Asia were shown to have the highest levels of hunger.
The report's authors called on nations to tackle child malnutrition in order to reduce global hunger. (Thanks Muna)
