Caffeine common in kids, young adults; mainly soda

CHICAGO — Nearly 3 out of 4 U.S. children and young adults consume at least some caffeine, mostly from soda, tea and coffee. The rate didn’t budge much over a decade, although soda use declined and energy drinks became an increasingly common source, a government analysis finds.

Though even most preschoolers consume some caffeine-containing products, their average was the amount found in half a can of soda, and overall caffeine intake declined in children up to age 11 during the decade.
