A new study finds that if you consume just one energy drink could increase your risk of heart attack and stroke in just 90 minutes.
Researchers from the University of Texas at Houston claim the drinks narrow blood vessels, which restricts blood flow to vital organs.
Studies in the past have linked energy drinks – such as Red Bull, Monster and 5-Hour Energy – to problems with the stomach, nerve and heart.
Among the findings the team are the first to shed light on the possible mechanism linked to high consumption of energy drinks with an increase in risk metabolic syndrome.
Consuming energy drinks can narrow blood vessels, restricting blood flow and increasing the risk of heart attacks and strokes according to a new recent study.
The team looked at 44 students from the McGovern Medical School at UTHealth for the study.
All of the participants were in their 20s, non-smoking and classified as ‘healthy’.
Researchers tested the function of the endothelium, a layer of cells that line the surface of blood vessels.
Endothelial dysfunction has been an indicator of heart attacks because the arteries are unable to fully dilate, according to Cedars-Sinai Medical Center in Los Angeles.
Each of the students drank a 24 ounce energy drink before the team tested the participants’ endothelial function and again 90 minutes later.
The researchers looked at the students’ artery flow-mediated dilation, an ultrasound that measures overall blood vessel health during the test.
The internal diameter of blood vessels, on average, had been cut by nearly half in almost 90 minutes.
A negative effect on blood vessels could be related to the effects of ingredients in the energy drinks – including caffeine, taurine, sugar and other herbals – on the endothelium according to the team.
The majority of energy drinks contain a high level of sugar. Look at one 12-ounce can of Red Bull which contains 37 grams of sugar – that the equivalent of almost nine teaspoons.
Research has indicated that high blood sugar levels can make bloods vessels contract more than normal, reducing the amount of blood that reaches vital organs.
Which means these drinks contain 80 milligrams of caffeine per 250 milliliters – about the same as 2.5 cans of Coca-Cola.
Caffeine also causes blood vessels to contract and releases adrenaline, a hormone that temporarily increases blood pressure.
Almost one-third of American teens between 12 and 17 years old consume energy drinks regularly, according to the National Center for Complementary and Integrative Health.
‘As energy drinks are becoming more and more popular, it is important to study the effects of these drinks on those who frequently drink them and better determine what, if any, is a safe consumption pattern,’ said Dr John Higgins, a professor of medicine at the McGovern School.
Scientists have been shedding light on many ill effects that energy drinks cause in recent times.
A study back in April 2017 from the David Grant USAF Medical Center in California found the following:
One 32-ounce energy drink can trigger an arrhythmia, a condition in which causes the heart beat to become irregular or abnormal rhythm.
In February 2018 another study from the University of Waterloo in Ontario, Canada, concludes this:
Half of Canadian teenagers who consumed energy drinks experienced health problems, including rapid heartbeat, nausea, and in rare cases, seizures.
These new findings will be presented in Chicago at the American Heart Association’s Scientific Sessions 2018, from November 10 to November 12.
