A new report finds that a large cup of Starbucks coffee contains more than three quarters of the maximum daily dose of caffeine recommended for healthy adults and nearly double the recommended limit for pregnant women. How does your favorite energy drink, cup of espresso, or even hot chocolate stack up?
"People often don't understand the potential risk of these beverages," University of Florida's director of forensic toxicology, Bruce A. Goldberger, told Chemical and Engineering News. "Caffeine is a stimulant and, when consumed at high enough levels, can have negative effects."
"Whereas low-dose caffeine effects are wakefulness, a little bit of arousal, and slight euphoria," Bertil B. Fredholm, emeritus professor of pharmacology at Sweden's Karolinska Institute, said in the report, "high-dose effects are anxiety, irritation, and general mental discomfort -- a completely different kettle of fish."
Yet scientists say that tolerance levels for caffeine can vary widely between individuals. Drug use can also affect caffeine tolerance. Women who take contraceptive pills break down caffeine more slowly, while smokers tend to process the stimulant at a faster pace than non-smokers.
