A Canadian study has linked energy drink shots and diabetes risk in teens. Higher blood sugar levels and insulin levels were found in those teens who consumed the drinks, indicating insulin resistance.
The researchers believe that the effect may be an indication that type 2 diabetes could develop later in life.
For the study, teens drank a bottle of 5-hour Energy, which has 208 milligrams of caffeine but no sugar. They also drank a decaf version of 5-hour. They were not able to metabolize sugar as efficiently after drinking the caffeinated version as they were when they drank the decaf.
They experienced a 25 percent increase in their blood sugar levels and their blood insulin levels.
“It’s the caffeine,” said senior researcher Jane Shearer, an assistant professor and diabetes researcher at the University of Calgary in Canada. “The elevated caffeine content in energy drinks is what causes this response.”
