Caloric intake from fast food among adults: United States, 2007-2010.

An earlier report by the U.S. Department of Agriculture found that the percentage of adults eating fast food increased from the early 1990s to the mid-1990s (1). Moreover, previous studies have reported that more frequent fast-food consumption is associated with higher energy and fat intake and lower intake of healthful nutrients (1,2). This report indicates that for 2007–2010, on average, adults consumed just over one-tenth of their percentage of calories from fast food, which represents a decrease from 2003–2006 when approximately 13% of calories were consumed from fast food. During 2007–2010, the highest percentage of calories from fast food was consumed among adults who were aged 20–39 or non-Hispanic black or obese. Among young non-Hispanic black adults, more than one-fifth of their calories were consumed from fast food.
