Years of research identified various serious health risks associated with a reduction in the number of energy drinks, such as liver damage, increased blood pressure, tooth erosion and much more.

Despite warnings, energy drinks are still among the most widely used additives in the United States. In fact, according to the National Center for Complementary and Integrative Health, "almost one third of teenagers between 12 and 17 years of age drink regularly."
Now, a new study to be presented at the American Heart Association in Chicago next week suggests that taking only one drink can lead to negative effects on the function of the blood vessel.
For research, scientists at McGovern Medical School in Houston examined 44 young and healthy medical students in their 20s. They tested the baseline function of the endothelium (or blood vessel function), and then tested it again 90 minutes after the participants consumed an energy drink of 24 ounces. Endothelial function is a potent indicator of cardiovascular risk.

The researchers also recorded an arterial flow dilatation using ultrasound which revealed the overall blood vessel's ability to heal before and after a 90-minute rating.
What they found was acute damage to the vascular function after just one drink. Initially, the expansion of the ship was an average of 5.1 percent in diameter. After 90 minutes and one drink later, the ship's dilatation dropped to 2.8 percent in diameter.
According to leading researcher John Higgins, reduction can limit blood flow and delivery of oxygen.

"It's more work for the heart and less supply of oxygen for the heart, which could explain why there were cases when children had a heart failure after an energy drink," he told HealthDai.
The reduction effects may eventually lead to an increased risk of high blood pressure, coronary heart disease, stroke, or rheumatic heart disease, in addition to other vascular diseases.
Although the study is small and only examines the acute effects of energy drinks, Higgins and his colleagues consider that the combination of caffeine, taurine, sugar and other ingredients is responsible for any adverse effects.

As the American Heart Association has previously noticed, "added sugars contribute to zero-nutritional ingredients, but many add calories that can lead to extra pounds or even obesity, which reduces heart health."
And while caffeine is associated with health benefits, the recommended daily limit is 400 milligrams for adults. However, some energy drinks contain more than 200 milligrams per ounce, including concentrated so-called "energy footage".

However, industrial groups claim that their drinks are safe.
"The main energy drinks contain about half a caffeine of similar coffee coffee of a similar size and have been widely studied and confirmed for consumption by government security authorities around the world," said Villiam Dermodi, a spokeswoman for the American Drinking Association. study. "Nothing in this preliminary study does include this well-established fact."
The researchers will present their findings on Monday, November 12, which are considered preliminary until they are published in the journal.
