Proper nutrition is a powerful good: people who are well-fed are generally healthy. Healthy women can lead more fulfilling lives; healthy children learn more in school and out. Good nutrition benefits families, their communities and the world as a whole. Malnutrition is, by the same logic, devastating. It plays a part in more than half of all child deaths worldwide. It perpetuates poverty. Malnutrition blunts the intellect and saps the productivity of everyone it touches, says a new report released by Unicef for the World Economic Forum.
