The popularity of ice creams, yogurts, and even jelly beans with high caffeine levels is causing experts to call for labels listing how much a product contains. Manufacturers aren't currently required to disclose caffeine levels, and advocates for stricter labeling say this makes it difficult for people to cut back on caffeine and for pregnant women to adhere to the FDA's recommended maximum.
Coke and Pepsi agreed to voluntarily disclose caffeine levels—23 and 25 milligrams per 8-ounce serving, respectively—but a study found other sodas contain anywhere from 5 to 75 milligrams per serving. Some candy bars and ice creams can contain far more caffeine than a can of soda. "It turns up in unexpected places," one advocate tells the Los Angeles Times. "There's no way to keep count."
