High amounts of sugar and caffeine can
aggravate underlying heart issues, causing fatal arrhythmias

Energy drinks the
cause of many sudden cardiac deaths in young people, researchers find.
To many
adolescents and young adults, energy drinks have become essential for getting
through the day. But they carry a serious risk of sudden death, a new study
finds.
An
international research team, led by Dr. Fabian Sanchis-Gomar of Madrid,
Spain, has concluded that energy drinks are the cause of many sudden cardiac
deaths in young, healthy individuals.
The main
concern is that these beverages can easily aggravate underlying heart issues.
Because of
their high amounts of caffeine and sugar, dangerous arrhythmias can easily
develop in the hearts of young people who drink them.
Many people
already balk at the high amounts of labeled caffeine on these drinks.
The problem is
that there are many additional sources of caffeine that are “masked” by the
labeling.
"Masked" caffeine
Ingredients
such as guarana, ginseng, and taurine have caffeine concentrations that are
equal to, or higher than, caffeine found in coffee.
Ingesting high
doses of any of these substances can be very dangerous.
Roughly 31% of
adolescents from ages 12 to 19 consume energy drinks on a regular basis.
An even higher
number of people use alternatives to these beverages, such as gums or inhalers.
The high
amounts of caffeine in all of these products is causing serious harm, the study
found.
Of the 5,448
caffeine overdoses reported in the United States in 2007, 46% of them occurred
in people under the age of 19.
The question
is, how can we halt this trend of overconsumption by young people?
Dr.
Sanchis-Gomar and his team came up with several guidelines to keep young people
from over-indulging. They caution that:
· One can (250
mL) of an energy drink per day is safe for most healthy adolescents.
· Energy drink
consumption before or during sports practice should be avoided.
· Adolescents
with clinically relevant underlying medical conditions should consult
cardiologists before drinking energy drinks.
· Excessive
energy drink consumption together with alcohol or other drugs, or both, may
lead to adverse effects, including death.
In the study
published in the Canadian Journal of Cardiology, Dr. Sanchis-Gomar goes on to say
alerting physicians to the dangers of energy drinks is extremely
important.
“It is important for physicians to
understand the lack of regulation in caffeine content and other ingredients of
these high-energy beverages,” he said. Knowledge and awareness are key to providing safety for young
people.
