Childhood Obesity: Backing projects that help reverse the childhood obesity epidemic by improving access to affordable, healthy food and providing more opportunities for children to play and exercise in their schools and communities. The Robert Wood Johnson Foundation's grants are focused on driving public policy initiatives and changing community environments. These include programs that encourage supermarkets to return to low-income communities and that improve nutrition, physical activity, and staff wellness in schools nationwide. The foundation partnered with The Food Trust, a non-profit in Philadelphia that helps make fresh, affordable food accessible to the underprivileged and educates children about healthy eating.
