It seems that the majority of American children aged 5-12 years old are hooked on caffeine coming primarily from soda; and it’s keeping them awake at night. According to the Journal of Pediatrics, kids ages 8-12 are consuming up to 109 milligrams of caffeine a day. That’s the equivalent of nearly 3 cans of soda or one cup of coffee. Unfortunately, researchers don’t know much about the health effects of caffeine in children since most studies have been done in adults. We do know that caffeine is a stimulant and soda consumption is linked to childhood obesity, so it’s not recommended. Parents are advised to limit their kids to an occasional cup of soda.
