US consuming less fast food, says CDC

According to the CDC, U.S. adults consumed about 11 percent of their daily calories in fast food during the time span, a slight drop from the roughly 13 percent consumed between 2003-2006.

The survey asked about 11,000 adults about their eating habits over the past 24 hours. It revealed that, in general, young people and African-Americans consume the most calories in fast food (15 percent for each group).

People who are obese also consume more fast food than their normal-weight peers, the CDC found.

In a separate study released Thursday, the CDC reported that young people consumed fewer calories between 2000-2010. The share of calories from carbohydrates, fats and proteins fell within recommended ranges, the agency said.
