study: It's the first federal study to look at how often adults eat fast food, according to CTV. An earlier study found a similar proportion of children and adolescents ate it on any given day. That's about 85 million people. The Centers for Disease Control and Prevention released the numbers Wednesday. The study did not find a difference between men and women. It's based on a survey of about 10,000 adults over four years. (www.immigrantscanada.com). As reported in the news.
