Aug. 31, 2011 -- Half of the U.S. population age 2 or older indulges in sugary drinks on any given day, new research finds.

"Men drink more than women, and teens and young adults drink the most," says Cynthia L. Ogden, PhD. Ogden is an epidemiologist at the CDC's National Center for Health Statistics.

The American Heart Association recommends drinking no more than 450 calories a week of sugar-sweetened drinks. That's less than three 12-ounce colas. In 2010, U.S. dietary guidelines recommended limiting the intake of both foods and beverages with added sugars.

Overall, men and boys drink an average of 175 calories from sugary drinks a day. That is more than one can of cola. Women and girls drank about 94 calories a day. That is less than one cola a day.

Sugary drink intake in the U.S. has increased over the last 30 years. Sugared beverages have been linked with weight gain, obesity, poor diet, and, in adults, type 2 diabetes.

The CDC report, "Consumption of Sugar Drinks in the United States, 2005-2008," was issued today.
