Where is malnutrition most common in the world?

Malnutrition is most common in low- and middle-income countries, particularly in regions such as Sub-Saharan Africa and South Asia. These areas often face challenges like poverty, food insecurity, and limited access to healthcare and education, which contribute to high rates of undernutrition and micronutrient deficiencies. Additionally, conflict and climate change exacerbate these issues, leading to increased vulnerability among populations. Addressing malnutrition requires comprehensive strategies that tackle both immediate needs and underlying causes.
