Studies Link Sugary Drinks, Weight Gain

Three new studies strengthen links between sugar-sweetened drinks and excess weight. The New England Journal of Medicine published them online September 21. Two studies involved children. One included 224 overweight and obese teenagers. They were randomly divided into 2 groups. One group received water and diet drinks delivered to their homes for a year. They were urged to avoid sugar-sweetened drinks and got regular pep talks. The other group got no drinks or advice. After a year, teens who got the free drinks had gained less weight than those in the other group. But a year after the program ended the difference had disappeared. A second study involved younger children who drank sugar-sweetened beverages regularly. Researchers gave each child a canned drink daily. One group got sugar-sweetened drinks.
