Meeting the Millennium Development Goals (MDGs) requires immediate action on nutrition. At this time a quarter of all children are undernourished. This increases their chance of death, undermines their potential to learn in school and reduces their capacity to earn a living. Proven solutions are available and nations want to act on this knowledge. Investments in Scaling-up Nutrition will yield immediate returns. They will save lives, enable children – and their mothers – to have a better future, contribute to livelihoods, reduce poverty and contribute to the economic growth of nations.
