ABILENE, Texas -

Americans are consuming less fast food, according to a Centers for Disease Control and Prevention study.

The study is based on adults’ daily caloric intake from 2007 to 2010 and found that, during that time period, 11.3 percent of adults’ total daily calories came from fast food. From 2003 to 2006, 12.8 percent of adults’ total daily calories came from fast food.

Dietitian Ansleigh Mills said the 1.5 percent decrease is not good enough.

“I think it's not a very significant decrease. I think we need to rely on our own selves for food sources instead of restaurants because we have more opportunities to choose what's in our foods when we prepare them ourselves,” Mills said. “Fast food contains a lot of calories simply because it's very high in fat and fat packs a lot of calories and very little food. It also contains a lot of sodium. So when we eat out we're getting a lot more fat, a lot more sodium, a lot more calories than if we would choose foods from home.”

According to the report, people between the ages of 20 and 39, non-Hispanic blacks and obese adults ate the most calories from fast food. Also, eating fast food on a regular basis contributes to weight gain and more than one-third of adults are classified as obese.
