It's a worldwide first: Today, eating too much is more of a health threat than food shortages. On a global scale, overeating costs more years of healthy life than does undernutrition, according to a massive new study. The Global Burden of Disease 2010 report compares illnesses and causes of death in 1990 with those in 2010, and it's "the most comprehensive assessment of human health in the history of medicine," says the editor of the journal publishing the study.
