Many parents are unaware their children are consuming too much caffeine, University of Nebraska Medical Center researchers found, and it is not good for their health, according to a post on the "contributed news" website All Voices.
The medical center surveyed the parents of more than 200 children 5 to 12 years old during routine clinical visits at an urban pediatric clinic. The researchers found that 75 percent of the children consumed caffeine on a daily basis, and the more caffeine the children consumed, the less they slept.
Children as young as 5 years old were consuming the equivalent of a can of soda a day. Children between the ages of 8 and 12 years consumed an average of 109 mg of caffeine a day, the equivalent of almost three 12-ounce cans of soda.
The All Voices post referred readers to a UC Davis nutrition and health info sheet titled "Some Facts About Energy Drinks," written by project scientist Karrie Heneman and Cooperative Extension nutrition specialist Sheri Zidenburg-Cherr.
The fact sheet said the caffeine content of a single serving of energy drink (8 to 12 oz.) can range from 72 to 150 mg, however, many bottles contain 2 to 3 servings, raising the caffeine content to as high as 294 mg per bottle. In comparison, the caffeine content in an 8-ounce serving of brewed coffee, tea and cola ranges between 134-240 mg, 48-175 mg and 22-46 mg respectively.
Other stimulants such as guarana and ginseng are often added to energy beverages and can enhance the effects of caffeine. Guarana, in particular, contains caffeine (1 g of guarana is nearly equal to 40 mg caffeine) and may substantially increase the total caffeine in an energy drink.
