ATLANTA (AP) -- Health officials say half of Americans drink a soda or sugary beverage each day -- and some are downing an awful lot.

A new study found that one in 20 drinks the equivalent of more than four cans of soda each day. The Centers for Disease Control and Prevention research also showed teenage boys drink the most soda, sports drinks and other sugary liquids.

Sweetened drinks have been linked to the U.S. explosion in obesity, and health officials have been urging people to cut back. Many schools have stopped selling soda or artificial juices.

The CDC report released Wednesday is said to be the first to offer national statistics for adults and kids. Past studies have focused on certain groups, particularly school kids.
