Researchers used new technology that measured participants' glucose (sugar) levels on a constant basis throughout the day. Dr. James Lane, a psychologist at Duke and the lead author of the study, says it represents the first time researchers have been able to track the impact of caffeine consumption as patients go about their normal, everyday lives.
The findings, appearing in the February issue of Diabetes Care, add more weight to a growing body of research suggesting that eliminating caffeine from the diet might be a good way to manage blood sugar levels.
