16.Food and drink makers are adding caffeine to a growing number of products.Is it safe for kids to consume these products?You may have heard adults say they can't get going in the morning without a cup of coffee.One reason why they may feel that way is that coffee contains caffeine,a substance known to improve and increase energy.Caffeine occurs naturally in coffee,tea,and cocoa beans,which are used to make chocolate.But now food makers are adding caffeine to many products,from popcorn and potato chips to water."It's possible for all of this caffeine consumption to add up and become dangerous,"says Virginia Stallings,a doctor at the Children's Hospital of Philadelphia.

So,what can be done to protect young people from the harmful effects of caffeine?Michael Jacobson of the Center for Science in the Public Interest,says the FDA needs to set limits on caffeine,especially in energy drinks.The amount of caffeine should be printed on food labels to warn consumers.Doctors say kids should avoid caffeine.If you need extra energy,try these natural methods instead:eating right,exercising,and getting plenty of sleep.
