A recent study found that the intake of coffee and energy drinks among kids has increased in the past year, while soda consumption has gone down. The study, conducted by the National Center for Health Statistics, found that kids getting their caffeine from coffee has gone up from 10 percent to 24 percent in the past 10 years, while caffeine intake from soda has decreased from 62 percent to 38 percent in the same time period.

The Food and Drug Administration has yet to set a safe caffeine consumption level for children, but it warns parents that excessive consumption can increase heart rate, blood pressure, hyperactivity, and anxiety. (PopSugar
