Today's "coffee culture" and the widespread availability of caffeine-containing foods and beverages fuel the ongoing study of caffeine and its subsequent coverage by the media. Although the media has become influential in communicating health and nutrition information to the public, coverage of emerging science, such as the study of caffeine, does not necessarily bring clarity or improved understanding for consumers. This article highlights the current knowledge of caffeine's effects on health, with emphasis on the most common areas of interest and confusion. To address persistent misperceptions about caffeine, this article also accentuates the need for nutrition professionals to help put the findings of caffeine research into perspective and suggests practical ways to do this.
