Do teenagers drink too many energy drinks?

A 2015 survey by the World Health Organization found that 14% of 11–15 year olds in England consumed energy drinks two to four times per week. Drinks companies make big bucks from these products. Questions about the health impacts of energy drinks on young people are growing, too. The recently launched ‘sugar tax’ hopes to address one issue: the vast amounts of sugar in each can. But awareness of a second health concern – high doses of caffeine – is lagging behind.
