WHO-FAO: International Conference on Nutrition: What is the double burden?

The ‘double burden’ is when hunger and obesity affect people within the same population.
The double burden of malnutrition is a situation where overweight and obesity exist side-by-side with under-nutrition in the same country. We see this a lot in countries that are going through fast economic growth, also known as the nutrition transition.
More than 800 million people go hungry yet half a billion people are obese.
While undernutrition still kills almost 1.5 million women and children every year, growing rates of overweight and obesity worldwide are driving a rise in diseases like cancer, heart disease, stroke and diabetes.
Ensuring access to a healthy diet and reducing exposure to foods high in fat, sugar and salt helps prevent malnutrition.
