It seems like a no-brainer. Since about 75 percent of healthcare spending in the United States is for largely preventable chronic illnesses such as Type 2 diabetes and heart disease, providing more preventive care should cut costs. If only. In a report released on Tuesday, the non-profit Trust for America's Health outlined a plan "to move from sick care to health care" by putting more resources into preventing chronic disease rather than treating it, as the current system does. There is a strong humanitarian justification for prevention, argued Trust Executive Director Jeffrey Levi in an interview, since it reduces human suffering.
