Are Energy Drinks Actually Dangerous?

Are Energy Drinks Actually Dangerous?

There’s no doubt that many of us live very fast-paced lives. “Too much to do in too little time…” It’s this common complaint that’s helping to drive the popularity of energy drinks. After all, who couldn’t use a little boost to help get through another busy day? And it’s not only adults who are fueling the craze. Teenagers are among the biggest users of energy drinks when they need to be awake for morning classes after staying out late or studying all night.

So what’s the problem? Energy drink-related visits to the emergency room have doubled over the past four years, and most of these cases have involved teens and young adults.

Energy drinks such as Red Bull, Monster, Full Throttle and Rock Star are starting to attract the attention of medical researchers and public health officials alike. This is leading to some troubling discoveries about what the ingredients in these drinks can do to our bodies. It’s also putting a spotlight on how these products are marketed. It turns out that energy drinks—unregulated and usually sold right alongside soft drinks in the supermarket—may be dangerous for our health.

What’s in the can? In addition to large amounts of caffeine and sugar, other ingredients commonly include taurine, glucuronolactone and guarana, as well as B-vitamins and a variety of herbal supplements such as ginseng, milk thistle and gingko biloba. The primary concern so far is the effect the combined stimulants in these drinks have on the heart. A typical energy drink contains up to three times as much caffeine as an equivalent amount of coffee or soda.

Energy drinks have been shown to produce arrhythmias (which are potentially life-threatening changes in your heart rhythm) and to raise blood pressure. Heart palpitations, seizures and sudden death can be caused when someone with an arrhythmia consumes an energy drink.

A study conducted by Dr. Jonas Dorner and colleagues from the University of Bonn in Germany found that energy drinks increase heart contractions. Dorner said “Until now, we haven’t known exactly what effect these energy drinks have on the function of the heart. There are concerns about the products’ potential adverse side effects on heart function, especially in adolescents and young adults, but there is little or no regulation of energy drink sales.”

The study involved 18 healthy volunteers, most of whom were male, who consumed an energy drink containing caffeine and taurine. They underwent an MRI an hour after taking the drink, and the results showed a significant increase in peak strain in the left ventricle of the heart.

Although these results may not cause problems in the short term for those who are young and healthy, these drinks may be a problem for anyone with heart disease. There are also no studies yet measuring the long-term effect that these energy drinks have on heart health.

Experts advise that children and anyone with a heart condition such as arrhythmia avoid consuming energy drinks due to the potential risks they pose.

Children and Caffeine: What Parents Should Know

Children and Caffeine: What Parents Should Know

girlThe next time you pass a Starbucks, pause for a moment and imagine that the customers inside drinking their lattes and Grande Espressos are your children. Then imagine them ingesting a drug (caffeine) that is known as a powerful stimulant with a proven history of producing nervousness, restlessness, irritability, high blood pressure, insomnia, headaches and heart palpitations. Finally, consider that this exercise in imagination may not be all that far off the mark.

That is the key finding of the Centers for Disease Control and Prevention (CDC) in a 2014 study published in the journal Pediatrics. The researchers found that nearly three out of four children and young adults in America (73%) consume some caffeine a day, mostly from soda, tea, and coffee, but also from an alarming number of “energy drinks.”

This study comes as part of an investigation undertaken by the U.S. Food and Drug Administration (FDA) into the safety of foods and drinks that contain caffeine—especially their effects on children and teens. In response to numerous reports of hospitalizations and even deaths after the consumption of highly caffeinated drinks or “energy shots,” the investigators analyzed health surveys containing data on over 22,000 subjects aged 2 to 22.

Many foods contain caffeine (including chocolate, candy bars, some jelly beans, and marshmallows), but most of the caffeine ingested by small children comes in the form of soda. The rise in the use of energy drinks—although they account for only 6% to 10% of children’s daily caffeine intake—is seen as particularly alarming, because many of these drinks contain even higher amounts of caffeine than soda.

The FDA study found that the average caffeine intake among participants was about 60-70 milligrams—roughly the same amount of caffeine present in a six-ounce cup of coffee or two sodas. However, this finding does not necessarily mean that this level of caffeine consumption is safe for children. In fact, while the FDA has classified caffeine as GRAS (generally recognized as safe), that classification is based solely on its use by adults. There is actually no current body of research analyzing its possible detrimental effects on children. Nakia V. Williams, M.D., a pediatrician at the Henry Ford Health System, says, “There haven’t been a lot of studies of caffeine in young children, but we do know that children suffer from similar side effects as adults, and that on average these side effects can occur at lower doses given the smaller body sizes.” The American Academy of Pediatrics (AAP) recommends against caffeine consumption for children and teens because of possible harmful stimulant effects as well as the possibility of it worsening anxiety in children already suffering from anxiety disorders. The AAP holds the clear position that “stimulant-containing energy drinks have no place in the diets of children and adolescents.”

So if you have kids, think twice before allowing them to consume soda and other drinks that contain caffeine. Pediatricians are unanimous in suggesting that they would be better off drinking water, reasonable amounts of fruit juices, milk, and other non-caffeinated beverages.
