Please comment on the impact of kids' caffeine intake.

With increased consumption of energy drinks among adolescents (concentrated "boosts" + coffee concoctions, heart attacks on sports fields, etc), could you give a definitive medical recommendation in terms of caffeine intake and/or safe consumption (short-long term impact concerns w/kids?)

Dr. Paolo Angeliniby Texas Heart Institute cardiologist, Paolo Angelini, MD    

The effect of caffeine is indeed the major worry about the use of caffeine in such drinks. Caffeine can make a person jittery, nervous, impulsive, anxious, and also increase blood pressure, increase the probability of arrhythmias and, in some patients with unusual predisposition, even induce cardiac arrest/sudden cardiac death. 

The basic message: a usual coffee cup has about 100 mg of caffeine. These drinks offered to sportspeople have a variable amount, and one needs to be aware. Such drinks have many more chemicals than caffeine and one needs to be knowledgeable. The FDA does not regulate similar drinks, neither for content nor for action...but this may come to be sometime in the future.
