FDA will investigate added caffeine in foods

The Food and Drug Administration says it will launch a new investigation into foods with added caffeine and their potential impact on the health of children and adolescents.

The FDA's new look at added caffeine is in response to a caffeinated gum introduced this week by Wrigley. Called Alert Energy Gum, it promises "The right energy, right now."

Michael Taylor, FDA's deputy commissioner of foods, said in a statement Monday that the proliferation of caffeine added to foods is "beyond anything FDA envisioned."

Taylor said the agency will look at the potential impact these "new and easy sources" of caffeine will have on children's health and will take action if necessary. The agency previously launched an investigation into the safety of energy drinks.
