Soft drinks advertised as flavored with fruit juices may contain as little as 5 percent real juice, according to a study by the Reebok Aerobic Information Bureau.

None of the more than a dozen brands examined contained more than 50 percent fruit juice, the study found. The balance was mostly sugar, water and artificial flavorings.If you want a refreshing drink made with fruit juice, you can make your own from juice and seltzer water at a lower cost than most soft drinks, the study concluded.
