The Risks of Energy Drinks
Posted on Jul 15, 2014
Ads for energy drinks are plastered on the walls of sporting events and on the jerseys of leading athletes. The beverage makers sponsor models, music events and videos games. Red Bull, the market’s leading drink, even has its own TV series and printed magazine. They claim to boost your immune system, enhance your performance, and help you stay up longer.
No wonder 30 to 50 percent of adolescents and young adults say they buy energy drinks. But are they safe for young people to drink?
“No,” says Stephanie Nguyen Lai, M.D., a pediatrician at the Palo Alto Medical Foundation. Energy drinks are loaded with caffeine – often twice as much as coffee and eight times as much as a soda. They’re especially dangerous when mixed with alcohol.
“As a parent, it is important to talk with your adolescent, and explain the risks of these products,” Dr. Lai says. “Their health could be at stake.”
Hidden Caffeine in Energy Drinks
The caffeine content in popular energy drinks varies greatly. It’s not regulated by the Food and Drug Administration (FDA). Ironically, some drinks do not even list the caffeine content on their label. Instead, it’s part of their secret “proprietary blend.”
Why does the FDA regulate soft drinks, but not energy drinks? The beverage makers claim that energy drinks are “natural dietary supplements,” thus not subject to the regulations that apply to food.
So your teen may not know how much caffeine he or she is drinking, and likely it’s a lot more than they realize. A typical 16 ounce energy drink contains between 150-280 milligrams of caffeine; larger cans have up to 500 milligrams of caffeine. By comparison, a 12-ounce can of soda can contains 35 milligrams of caffeine. See this list of caffeine content in popular drinks from the Center for Science in the Public Interest.
Many energy drinks also contain guarana, which is a South American plant with a more potent form of caffeine. One gram of guaranine (a derivative of guarana) is equivalent to 40 milligrams of caffeine. In reality, these drinks can contain much more caffeine than stated on the packaging.
The Side Effects of Too Much Caffeine
The side effects of too much caffeine are well known. They include:
- increased heart rate
- high blood pressure
Caffeine withdrawal is associated with headache, marked fatigue, anxiety, tremors and irritability.
Energy drinks also contain other substances touted to improve energy, such as taurine, ginseng, Vitamin B, carnitine and bitter orange.
“Unfortunately, the safety and effects of daily consumption of these additives are not well known,” Dr. Lai says.
When Energy Drinks Are Mixed With Alcohol
Dr. Lai says she is most concerned with new products that mix energy drinks with alcohol. Many of these have packaging that’s similar to non-alcoholic energy drinks. Although you must be over 21 to buy the drinks, teens can often get them through friends or with fake IDs. It’s also becoming more common for teens to create their own cocktails by mixing energy drinks with hard liquor.
Combining high-caffeine energy drinks with alcohol may give a teen the perception that he or she isn’t as drunk as she really is. And when teens feel fewer effects from alcohol, they tend to drink more. This problem became apparent as early as 2010, where teens have been hospitalized – and nearly died – due to consumption of the alcoholic energy drinks.
The Bottom Line on Energy Drinks
In 2011, a clinical report published by the American Academy of Pediatrics (AAP) stated that, “rigorous review and analysis of the literature reveal that caffeine and other stimulant substances contained in energy drinks have no place in the diet of children and adolescents.”
Take time to talk this over with your child. If you have further questions, call your child’s pediatrician.
