Malnourishment is a serious threat to the health and wellbeing of many people across the planet. Also known as undernourishment, it can lead to both long term and short term health issues, and is often a self-sustaining cycle closely linked to poverty. The Food and Agriculture Organization estimated that there were close to a billion people -- 925 million -- who went undernourished at some point in 2010.
Two thirds of those people can be found in just seven countries: China, India, Ethiopia, Bangladesh, Indonesia, Pakistan and the Democratic Republic of Congo. In terms of how many people in a region are undernourished compared to the general population, sub-Saharan Africa ranks first. About 30 percent of the people who live there do not get enough food to be healthy.

According to the United Nations, more than 1 billion people go without enough food to be healthy. This has prompted the U.N. to declare world hunger as the worst health risk worldwide. While the global production of food might be enough to meet the needs of the globe's population, complicated issues such as transportation, politics and economics can prevent those in need from receiving what is otherwise excess food.
