The initiative highlights the cost of chronic diseases一the leading causes of death in the United States——and outlines ways that people Can prevent them，including better diet and increased exercise．“In the United States today,7 of 10 deaths and the vast majority of serious illness，disability and health care costs are caused by chronic diseases,"the Health and Human Services Department said in a statement．The causes are often behavioral——smoking，poor eating habits and a lack of exercise．“I am convinced that preventing disease by promoting better health is a smart policy choice for our future，”Thompson told a conference held to launch the initiatiative. “Our current health care system is not structured to deal with the escalating costs of treating diseases that are largely preventable through changes in our lifestyle choices."
