An energy drink can even be plain water, which is actually the best hydrating drink for most people. However, sports and energy drinks are advertised to appeal to those who play sports or need a surge of energy.
Although sometimes confused with sports drinks, energy drinks are a completely different product. They are available on the market to increase alertness and energy levels, by containing significant amounts of caffeine and as much or more sugar as in carbonated drinks.
Many energy drinks contain about 200 mg of caffeine, which is approximately the amount in two cups of brewed coffee. Other energy-boosting substances, such as B vitamins and herbs such as ginseng and guarana, may be added.
The most worrying part is the lack of regulation on the safety of these drinks, as well as aggressive marketing tactics aimed at adolescents. The Centers for Disease Control and Prevention reported that in 2007 1145 adolescents aged 12 to 17 years (energy drink is usually used by adolescents or students who drink it in excessive amounts for exams at night, or by young athletes before an important match) went to the emergency department, the reasons being related to energy drink consumption. In 2011, this number increased to 1499.
After water, sugar is the main ingredient in energy drinks. 360 milliliters of coca cola contains about 39 grams of sugar and there are 41 grams of sugar in an energy drink.
Studies have shown that drinking high-sugar beverages of all kinds can lead to weight gain and increased risk of type 2 diabetes, cardiovascular disease and gout.
Due to the amount of sugar and stimulants, there are assumptions, that these drinks may not be healthy and even worse - they may be harmful to adolescents and people with certain health problems.
