Implementation of the Healthy Hunger-Free Kids Act of 2010 will provide an opportunity for school nurses to intervene in the serious childhood obesity problem in the United States. Major changes in the management of the National School Lunch Program (NSLP) will likely challenge schools yet may provide the impetus for a collaborative effort by the interdisciplinary school staff and parents to make a real difference for children. School nurses must use this occasion for a change to promote healthy eating habits and increased physical activity levels for students to carry into adulthood.
