As we move into the post-2015 era of the sustainable development goals (SDGs), the world faces many seemingly intractable problems. Malnutrition should not be one of them. Countries that are determined to make rapid advances in malnutrition reduction can do so, and the incentives to improve nutrition are strong. Good nutrition provides a vital foundation for human development, central to meeting our full potential. When nutrition status improves, it leads to a host of positive outcomes for individuals and families. Many more children will live to see their fifth birthdays, their growth will be less disrupted, and they will gain in height and weight. They will learn more in school because their brain function is not impaired. As a result of this positive early environment, as adults they will have better jobs and get ill less often. Older adults will age more healthily and live longer.
