Barriers and Challenges to Estimating Caffeine Intake

/in /by

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.

Beverage Caffeine Intake Study

/in /by

A large variety of new caffeinated beverage products have entered the market in recent years, including new types of energy drinks, cold brew and ready-to-drink specialty coffees and teas, and caffeinated waters and sports drinks. With shifts towards remote work and learning, online food and grocery ordering, and rapid pickup and delivery options for consumers, an updated evaluation of beverage consumption patterns and caffeine intakes in the U.S. population is warranted. The study will provide a current perspective on caffeinated beverage consumption patterns and caffeine intakes from a nationally representative sample of the U.S. population.
