An article that appeared on TIMES, says that doctors are concerned about the health effects of energy drinks because of a new research that reveals that consuming energy drinks may increase blood pressure and modify the heart rhythms of healthy humans.
The findings of the research, which was presented at a meeting of the American Heart Association in Phoenix, last Tuesday, adds to growing concern over energy drinks that combine ingredients like caffeine, guarana and ginseng into a potent stimulant.
Researchers tested 27 healthy adults under age 40 in the small study. Participants who consumed two energy drinks saw a statistically significant increase in abnormal heart behavior and a rise in blood pressure when compared to a control group given a placebo. Both of these conditions lasted two hours.
The new research is far from the first study to caution that energy drinks may lead to adverse health effects. A 2015 study in the journal JAMA found that energy drinks raised blood pressure and caused a stress hormone in young people.
In the study, the researchers had 25 healthy men and women drink a 16-ounce Rockstar energy drink on one day, and a placebo drink on another day. The researchers then measured the men and women’s blood pressure and their levels of the stress hormone norepinephrine before the trial and 30 minutes after they drank the beverage. They found that blood pressure levels went up and norepinephrine levels rose twice as much after people drank the energy drink compared to when they drank the placebo beverage.
Specifically, they found that mean blood pressure increased 6.4% after drinking the energy drink compared to the 1.0% increase seen with the placebo. Norepinephrine levels increased 73.6% after drinking the energy drink compared to 30.9% after drinking the placebo beverage.
Researchers behind the new study recommended that consumers, particularly young people, await further research before regularly drinking energy drinks.
