There's no doubt: Americans love soda.
The Centers for Disease Control and Prevention says half of all Americans drink soda or sugary drinks each day.
The report finds one in 20 people drinks the equivalent of more than four cans of soda a day. Sugary beverages are most popular among teenage boys. 70 percent drink one a day.
"They like soda, so one cup a day cause it has a lot of sugar, so that's fine," said John Bellini, Parent.
But health officials warn its not fine. Sugary drinks are linked to the explosion of obesity in the U.S, which goes hand in hand with heart disease and diabetes.
Now health directors from the country's biggest cities are teaming up with the Center for Science in the Public Interest to try to help Americans cut back. They're launching a new ad campaign that hopes to cut the average consumption of sugary drinks to three a week by 2020.
"What we know is, if we want to decrease these preventable causes of premature death and disability and disease, this is one of the places to start," said Dr. John Fielding, Dir. LA County Health Dept.
But with sugary drinks the single largest source of calories in the American diet, health officials admit it's going to be difficult to curb America's addiction .
