Doctors have called the drinks, "killing" the vessels

Even one energy drink can harm blood vessels.

Energy drinks have been associated with a host of health problems, including conditions that relate to heart, stomach, and nerve function. But, Katz said, "this is a small study looking only at acute effects and can not be considered proof that energy drinks injure the cardiovascular system over time". New research comes to explain how such beverages interact with our cardiovascular systems.

According to Cedars-Sinai Medical Center in Los Angeles, endothelial dysfunction has been shown to be an indicator of heart attacks because the arteries are unable to dilate fully.

According to a new study, young, healthy men and women experienced notably diminished function soon after consuming a single regular 24 U.S. oz can - equivalent to almost three 250ml cans of Red Bull cans or one-and-a-half 500ml cans of Monster Energy.

The team checked the participants' artery flow-mediated dilation, a measurement that indicates the overall health of blood vessels. At the initial stage of expansion vessels averaged 5.1% in diameter. This negative effect on blood vessels may be related to ingredients in the energy drink, such as caffeine, taurine, sugar and other herbals, the researchers suggested.

These drinks also have 80 milligrams of caffeine per 250 milliliters - about the same as 2.5 cans of Coca-Cola.


It also releases extra stress hormones - such as adrenaline - which can temporarily increase blood pressure.

According to the National Center for Complementary and Integrative Health, nearly one-third of American teens between 12 and 17 years old consume energy drinks regularly.

To investigate, John Higgins from the McGovern Medical School at UTHealth in Houston and colleagues recruited 44 healthy, non-smoking individuals, all in their 20s and tested their endothelial function before they had consumed an energy drink.

In the last few years, scientists have been shedding light on several ill effects that energy drinks can cause.

The American Heart Associating in a study carried out recently, has said that consuming just one energy drink may be detrimental to blood vessel function. "This could explain why there have been cases where kids have had a cardiac arrest after an energy drink", he said.

They found that within 90 minutes, the internal diameter of blood vessels had been reduced by half.
