Who We Are

1,000 Days promotes action and investment in nutrition to build a strong foundation for children, their families and their nations to thrive.


“We need to change the way we all look at nutrition, childhood obesity and what causes a lack of good health — from the earliest days. That will help us prevent the worst diseases and health outcomes for the newest generation.”
