Study: Only one energy drink will degrade blood function



DALLAS – Energy drinks remain very popular among young adults, but a new study finds that drinking only one leads to markedly impaired blood vessel function, even in healthy people.

The authors believe that energy drinks, which usually contain caffeine, taurine and other herbal supplements along with a high amount of sugar, may be detrimental to the lining of the blood vessels.

For the study, students from McGovern Medical School in Texas at Houston Health Science Center watched 44 students of healthy medical studies at their age of 20. Participants tested blood vessel function before 24-ounce of energy drink and then 90 minutes after drinking.

The authors used ultrasound technology to measure dilatation mediated by artery flow, the reading used to determine the overall blood vessel status. The results showed that vessel dilation declined from an average of 5.1 percent before participants consumed an energy drink at 2.8 percent 90 minutes later. Such reduction suggests acute damage to the vascular function or blood flow in the arteries.

"Since energy drinks are becoming more and more popular, it is important to study the effects of these beverages on those who often drink them and to find out what it is if there is a safe way of eating," the authors wrote.

The results of the study will be presented at the American Heart Association 2018 Scientific Sessions in Chicago.

In 2014, the World Health Organization warned that energy drinks may pose a threat to public health, and studies published last year in the journal Boundaries in public health found that they can cause kidney damage, increased blood pressure and even mental health problems.
