MONTGOMERY, Ala. - Looking for a quick pick-me-up to get through a long afternoon? Forget that cola. A fizzy citrus drink could provide even more of a boost. A new study shows that citrus-flavored sodas often have a higher caffeine content than the most popular colas. The research also found that caffeine content can vary widely from brand to brand, and even within a brand.
The Food and Drug Administration does not limit the amount of caffeine in foods. FDA spokeswoman Veronica Castro said a 0.02 percent caffeine content is generally recognized as safe for cola-type beverages.
For a 12-ounce soft drink, that's about 72 milligrams of caffeine.
The study by Bell and co-author Ken-Hong Chou found caffeine content in 12-ounce sodas ranged from 4.9 milligrams for a store brand of cola to 74 milligrams in Vault Zero, a citrus drink.
Caffeine content of well-known national brands include: Coca-Cola (33.9 milligrams), Diet Pepsi (36.7 milligrams), Pepsi (38.9 milligrams), Dr Pepper (42.6 milligrams), Diet Dr Pepper (44.1 milligrams), Diet Coke (46.3 milligrams), Mountain Dew (54.8 milligrams) and Diet Mountain Dew (55.2 milligrams).
By comparison, according to the American Beverage Association Web site, a 12-ounce cup of coffee has between 156 and 288 milligrams of caffeine, and the same amount of tea has 30-135 milligrams.
Bell said the data provided by manufacturers of national brand soft drinks was consistent with the findings of his study. He said the caffeine data for store brand drinks is not easy to find and often isn't available at all.
