Caffeine Science at IAFNS

The IAFNS Caffeine Committee mobilizes members from government, industry and academia to drive, fund and lead actionable science

Caffeine and Public Health

Through its tripartite model—bringing together scientists from government, academia, and industry—the The Caffeine Committee promotes scientific evaluation of health and safety issues related to caffeine consumption and serves as a resource for reliable, peer-reviewed science on caffeine to support the advancement of public health.

 

Why is this Research Valuable?

Caffeine is one of the most widely consumed food components and its ability to act as a stimulant is the primary reason for its consumption. Consumed by solid majorities of the population both in the U.S. and globally, levels of caffeine exposure are of considerable interest. The predominate source of caffeine is from beverages but caffeine can also be found in cocoa or chocolate-containing foods, dietary or herbal supplements, and medications. Caffeine is naturally occurring in coffee and tea but added to soft drinks and energy drinks.

The caffeinated beverage marketplace is continually evolving, resulting in considerable interest in understanding the impact caffeinated beverages have on levels of intake and exposure. Therefore, estimates of caffeine intakes are informative to public health.
