Ever chug a can of let鈥檚 say, Brand E, energy drink and not only feel that good-as-advertised jolt of extraness but experience a skip or two in your chest as well? Even though most of the evidence is anecdotal and the studies鈥攚hich continue to pile up鈥攄on鈥檛 yet know exactly why, the link between energy drinks and a racing heart (or worse) seem pretty incontrovertible.
The latest report to make this connection concluded that energy drinks can cause 鈥渁ngina, cardiac arrhythmia (irregular heartbeat) and even sudden death.鈥 This finding confirms that of a similar report from a year ago鈥攁nd confirms some people鈥檚 popular conceptions (or misconceptions) that energy drinks should be imbibed with caution鈥攁nd most probably in moderation, and almost definitely not right before or during any sort of trying physical activity.
鈥淢ost 鈥榚nergy drinks鈥 have contents that can be good or bad, depending upon the dose鈥攕ugar, caffeine, and taurine,鈥 says Dr. Kim Williams, chief of cardiology at Chicago鈥檚 Rush University Medical Center. 鈥淎t this time, though, there is no definitive way of determining which if any ingredient is the most harmful or under what circumstances.鈥
But with over 30 deaths allegedly related to consumption of energy drinks, adds Dr. Williams, 鈥渢hese incidents suggest that the ingredients, alone or in combination, may not be safe for all consumers if taken in large quantities, quickly, or if combined with alcohol or exercise in a heated environment.鈥澨
Most of Williams鈥 colleagues agree. Last year, for instance, The American Medical Association鈥檚 house of delegates voted to ban sales of energy drinks to those under age 18, suspecting that the high caffeine levels were harmful. Partly in response, no doubt, to the news that hospitalizations associated with energy drinks doubled from 2007-11, hitting 20,000, according to a report from the Substance Abuse and Mental Health Services Association.
鈥淲e don鈥檛 have enough data to conclusively state what in energy drinks may pose an increased cardiovascular or other risk,鈥 says Sachin Shah, associate professor of pharmacy at the University of the Pacific. 鈥淚t does seem that the adverse effects are more prominent in those consuming multiple beverages鈥攈igh volumes鈥攐r in combination with other drugs of abuse.鈥
Banned in France, Norway, and Denmark, and considered a prescription drug in Sweden, energy drinks appear to have been unleashed on U.S. consumers before an adequate number of studies could gauge all their possible effects. Particularly when individuals drink more than they should (which is, of course, vague鈥攁nd problematic when no one has established exactly how much is too much).
Most contain caffeine (source of all that 鈥渆nergy鈥) and while ingesting up to 400 milligrams a day is generally considered safe, there鈥檚 really no cutoff point for ingredients like taurine, which is also in most of these drinks.
Basically, more data is needed. 鈥淪o for now,鈥 says Shah, 鈥淚 tell my friends to limit their use to when necessary only, not to drink high volumes of it, not to confuse them as sports or electrolyte replacement beverages, and to stay away from them if having any underlying cardiac conditions.鈥
