Energy drinks destroy the arteries in 90 minutes

Scientists at the University of Texas at Houston have said that energy drinks have narrowed blood vessels, which limits blood flow to vital organs in the body.

Previous studies have linked energy drinks such as "Red Bull", "Monster" and "5 Hour Energy" with problems in the stomach, nerve and heart.

But the Texas University team says his findings are among the first to illustrate a potential mechanism that combines energy consumption with increased metabolism.

During the study, the team looked at data from 44 students at the McGovern School of UTHealth. All participants were 20 years old and classified as health and non-smoking.

Scientists wanted to test the function of the membrane lining, a layer of cells lining the surface of the blood vessels.

According to the research team, the endothelial function has failed, which is a sign of heart attacks because the arteries are not able to fully expand.

The team tested the endothelial function of the participants before each of them drank an energy drink, which is about 700 ml, and then tested again after 90 minutes.

Thereafter, scientists looked at the expansion of the arteries as the blood flow, which is known as "flow-mediated dilation".

Only 90 minutes after the energy drink, the blood flow in the inner diameter of the blood vessels was reduced by half.

The team suggests that a negative effect on blood vessels may be associated with the effects of energy drinks, including caffeine, taurine, sugar and other herbs, on the membrane lining.

Most energy drinks contain high levels of sugar, and research has shown that high blood sugar levels can cause blood vessels to decrease more than usual, reducing the amount of blood that interferes with vital organs.

Energy drinks also contain 80 mg caffeine per 250 ml, and this component may cause adrenaline excretion in the blood vessels, a hormone that can temporarily increase blood pressure.

"As energy drinks become more popular, it is important to study their effects on those who are often drunk and to see if there is a safe pattern of consumption," said Dr. John Higgins, McGovern School of Health Scientist.
