A new government study has found that one in three American adults eat fast food on any given day. That's comes out to about 85 million people.
This is the first federal study to look at how often adults eat fast food. An earlier study found a similar number of children have fast food on any given day.
The Centers for Disease Control and Prevention put out the numbers today. It's based on a survey of about 10,000 adults over four years.
The study did not find a difference between men and women. But higher-income families ate fast food more often than lower-income families, and African Americans ate it more than other racial or ethnic groups.
Health officials say too much high-calorie fast food can lead to obesity, diabetes, heart disease and other health problems.
