A relatively new phenomenon, energy drinks have become incredibly popular, with from just 2002 to 2008 alone. And despite bans on the drinks on , in , and on sales to minors, the downsides may not be well-known— or at least not well-known enough to curb sales Malinauskas, B.M., Aeby, V.G., Overton, R.F., et al.

Sugar High — The Need-to-Know

Dangerfood: Energy Drinks

Though often marketed separately, energy drinks are basically amped-up soda with some potentially Arria, A.M., O'Brien, M.C. Center on Young Adult Health and Development, Department of Family Science, University of Maryland School of Public Health, College Park, MD. Journal of the American Medical Association, 2011 Feb 9;305(6):600-1.. Super-sized energy drinks are often — one brand even has as much sugar as ! And it looks like the dentist was telling the truth: All that sugar actually could — more than standard sodas, even Kitchens, M., Owens, B.M. Journal of Clinical Pediatric Dentistry, 2007 Spring;31(3):153-9..

But it’s not just sugar that makes energy drinks a dangerous choice. Many also contain higher-than-healthy doses of caffeine, anxiety, insomnia, irregular heartbeat, and increased blood pressure. All that caffeine also acts as a diuretic, which can lead to dehydration Riesenhuber, A., Boehm, M., Posch, M., et al. Department of Pediatrics, Medical University of Vienna, Vienna, Austria. Amino Acids, 2006 Jul;31(1):81-3.. About 400-450 mg of caffeine per day is considered safe for most adults, but it’s easy to overdo it with energy drinks Knight, C.A., Knight, I., Mitchell, D.C., et al. Knight International, Chicago, IL. Food and Chemical Toxicology, 2004 Dec;42(12):1923-30.. Though 8-ounce cans typically keep the caffeine many manufacturers also have super-sized versions (sometimes nearly !) and concentrated energy “shots” that often contain over 200 mg.

Energy drinks allegedly owe their stamina-boosting powers to more than just caffeine, though. One popular addition is taurine, an amino acid naturally found in foods like meat and fish and a necessary component in our diets Birdsall, T.C. Thorne Research, Inc., Dover, ID. Alternative Medicine Review, 1998 Apr;3(2):128-36.. While some research supports the use of , long-term studies haven’t proven its safety (or usefulness) as a supplement. Other herbs (like ), and . Often, the supplements’ reps are shaky at best, and a healthy diet likely — no need to pack in the extra sugar. Plus, while labels may tout the magical contents of these cans, the additions may not even be in high enough concentrations to yield the intended results Clauson, K.A., Shields, K.M., McQueen, C.E., et al.

Jitter Bug — Your Action Plan

While energy drinks can be problematic for many, they can be especially troublesome for certain groups of people. While 30 to 50 percent of adolescents and young adults indulge, this population is more likely to experience negative side effects— including seizures, diabetes, cardiac abnormalities, or mood and behavioral disorders— than adults Seifert, S.M., Schaechter, J.L., Hershorin, E.R., et al. Department of Pediatrics and Pediatric Integrative Medicine Program, University of Miami, Leonard M. Miller School of Medicine, Miami, Florida. Pediatrics, 2011 Mar;127(3):511-28.. And while the increase in blood pressure caused by energy drinks isn’t usually a problem for healthy adults, those with existing heart problems are for dangerous side effects.

Add alcohol, and there’s an even bigger chance for disaster. Red bull and vodka might be , but the stimulants in the energy drink can mask the effects of the alcohol, consumption like impulsive behavior Arria, A.M., Caldeira, K.M., Kasperski, S.J., et al. Center on Young Adult Health and Development, Department of Family Science, University of Maryland School of Public Health, College Park, MD. Alcoholism, Clinical and Experimental Research, 2011 Feb;35(2):365-75. doi: 10.1111/j.1530-0277.2010.01352.x..

With energy drinks off the table, try turning to caffeinated black coffee and green tea for a healthier energy boost. Plus, they even offer additional health benefits like high doses of antioxidants. Other sources of a natural jolt include high-protein, high-fiber (though beware of those with high sugar content), , and even a quick run on the treadmill Williams, G., Noakes, M., Keogh, J., et al. CSIRO Human Nutrition, Adelaide, Australia. Asia Pacific Journal of Clinical Nutrition, 2006;15(4):443-50.. And then, of course, there’s always catching a few zzz's.
