    A cold drink may be just the thing. But be carefu "I what you pour down your throat; something that looks

         There are plenty of so-called energy drinks on the market. Most of them have an attractive color and
    cool name.
         But after a careful check you may find that most energy drinks have high levels of caffeine. These drinks
    are specially aimed at young people, students, busy people and sports players. Makers sometimes say their
    drinks make you better at sports and can keep you awake. But be careful not to drink too much.
         Caffeine raises your heartbeat. Because of this, the Intemational Olympic Committee has limited their use.
    The amount of caffeine in most energy drinks is at least as high as in a strong cup of coffee or strong tea.
         Research by Australian scientists has found that many teenagers are affected by caffeine. The results of
    their study show that 27 percent of boys aged 8-12 take in more caffeine than their parents. There are hidden
    health problems connected to energy drinks. Just one can of energy drink can make you nervous, have
    difficulty sleeping and can even cause heart attacks.
         "Teenagers should not be encouraged to have drinks with high level caffeine in them," a scientist from
    the Australia Nutrition Foundation said.
