Barriers and Challenges to Estimating Caffeine Intake

There is a need for peer-reviewed literature that provides good guidance on how to determine caffeine intake in individuals consuming caffeine and for research where caffeine intake is a factor that needs to be accurately assessed. The IAFNS Caffeine Committee will leverage high-resolution caffeine consumption data from the recent extensive survey sponsored by the committee, along with other published data, to develop a novel paper on the topic. The paper will include caffeine intake variables such as method of preparation, gender, and individual habits. The paper will be a resource for stakeholders seeking more accurate caffeine intake estimates in the US including beverage companies, government regulators and dietitians.
