If you’re a coffee drinker and your cup of choice is decaf, you might be surprised to learn there’s probably caffeine in that java. W-G-C-U’s Russell Lewis reports on the latest findings by University of Florida researchers. The U-F study found low-levels of caffeine in virtually all decaf coffees they analyzed. This included drinks purchased at Starbucks and brands you can buy at the supermarket. U-F Toxicology Director Bruce Goldberger co-authored the study. He says doctors order many people to limit their caffeine because of health reasons like high-blood pressure.

“There are people out there that do drink five and ten cups of decaf coffee a day. So that amount of caffeine can add up even to be the same as say as a pill of no-doze or equivalent to one, or two or maybe three cups of regular coffee depending on the strength of the caffeine in those coffees.”
