About 27 percent of the beverages consumed by Americans are soft drinks, the study notes. Overall soft drink consumption has steadily increased over the years and remains on the rise, contributing to an increase in oral health problems, namely cavities. In 1977, 12- to 19-year-olds drank 16 ounces of soda a day. In 1996, this same age group consumed an average of 28 ounces a day.

Soda consumption has increased from approximately 20 gallons per person per year in 1970 to more than 50 gallons per person per year in 2004. The American Beverage Association has stated that soft drinks account for 28 percent of overall beverage consumption. 

Soft drinks and canned beverages are constant features of daily life, and the approximately $50 billion the industry rakes in each year suggests it won't go away anytime soon. However, soda can be enjoyed in limited quantities. J. Anthony von Fraunhofer, MS, PhD, FADM, FRSC, lead author of the study, says that soda consumed "at meal times is less injurious than when consumed alone and continuous sipping is more harmful than the whole drink taken at one time."
