The strength and ingenuity of America’s people and communities have driven America’s success. A healthy and fit nation is vital to that strength and is the bedrock of the productivity, innovation, and entrepreneurship essential for our future. Healthy people can enjoy their lives, go to work, contribute to their communities, learn, and support their families and friends. A healthy nation is able to educate its people, create and sustain a thriving economy, defend itself, and remain prepared for emergencies. The Affordable Care Act, landmark health legislation passed in 2010, created the National Prevention Council and called for the development of the National Prevention Strategy to realize the benefits of prevention for all Americans’ health. The National Prevention Strategy is critical to the prevention focus of the Affordable Care Act and builds on the law’s efforts to lower health care costs, improve the quality of care, and provide coverage options for the uninsured. Preventing disease and injuries is key to improving America’s health. When we invest in prevention, the benefits are broadly shared. Children grow up in communities, homes, and families that nurture their healthy development, and people are productive and healthy, both inside and outside the workplace. Businesses benefit because a healthier workforce reduces long- term health care costs and increases stability and productivity. Furthermore, communities that offer a healthy, productive, stable workforce can be more attractive places for families to live and for businesses to locate.
