According to researchers at the Mayo Clinic, energy drinks increase risk of cardiac trouble in young people, by raising blood pressure. This is particularly true of those who are not used to caffeine.
“We know that energy drink consumption is widespread and rising among young people. Concerns about the health safety of energy drinks have been raised,” says lead author Anna Svatikova, M.D., Ph.D., cardiovascular diseases fellow at the Mayo Clinic.
The study participants informed the team of their usual caffeine consumption. Thjose who consumed less than one cup of coffee a day were considred caffeine-naive.
Researchers gave 25 healthy young adults between the ages of 19 and 40 a can of a commonly available energy drink or a can containing a placebo. They then assessed blood pressure and heart rate before consumption and at 30 minutes later. All those who drank the energy drink experienced a marked elevation in blood pressure.
