Studies reporting a link between sugar-sweetened beverages and weight gain have garnered a lot of attention but actually research on the issue has yielded mixed results, researchers note in a new report.
"The purported link between soft drinks and other beverages and obesity risk is unclear and complicated, especially in youth," Dr Mark A. Pereira, at the University of Minnesota in Minneapolis and an author on the report, told Reuters Health.
In a study Pereira and colleagues conducted, they found no link between weight gain over 5 years and teens' drinking of sugar-sweetened beverages. According to report in the American Journal of Clinical Nutrition, Pereira's team assessed diet, lifestyle, and weight in 2,294 ethnically-diverse boys and girls in the Minneapolis/St. Paul school system. Initially, when the teens were about 15 years old, 1,289 reported drinking 7 or more servings of white milk weekly, while 1,456 said they drank sugar-sweetened punch and 1,325 said they drank sugary soft drinks up to 6 times a week.
Additionally, about 1,300 of these teens said they drank up to 6 servings of apple juice or orange juice weekly. The investigators saw no overall association between consumption of sweetened beverages and the teens' weight gain over 5 years after allowing for other behaviours tied to beverage drinking habits and weight status.
