CARIBBEAN360 – Just one energy drink can cause potentially harmful spikes in both stress hormone levels and blood pressure in healthy young adults, according to a new study published in the Journal of the American Medical Association (JAMA).
Lead researcher Dr Anna Svatikova, a cardiologist at the Mayo Clinic in Rochester, Minnesota, said that after drinking a 16-ounce can of “Rockstar Punched,” young adults had a 74 percent increase in blood levels of the “fight-or-flight” hormone norepinephrine.
That’s more than double an average 30 percent increase in norepinephrine that the same participants experienced when they consumed a sham energy drink, according to Svatikova.
The fake energy drink contained the same amount of sugar and nearly the same calories, but did not include natural stimulants found in the Rockstar drink, she said.
The stimulants in the real energy drink included caffeine, the amino acid taurine, and extracts of guarana seed, ginseng root, and milk thistle.
