The study showed canadian experts from the University of calgary (University of Calgary), adolescents who use kodeinsoderjaschie “energy shots”, have a higher level of sugar and insulin in the blood due to insulin resistance caused by short term that, according to the researchers, could lead to further development of diabetes type 2.
For the experiment were selected in 20 adolescents aged 13 to 19 years who were randomly given either a regular energy drink “5-hour Energy”, or “5-hour Energy” without caffeine. Forty minutes later they passed the standard oral glucose tolerance test (PGTT).
The researchers found that adolescents who drank an entire bottle of energy, contains no sugar, but with 208 milligrams of caffeine, were unable to metabolize sugar as efficiently as they do when drinking the same drink without caffeine. Glucose tolerance test showed that in case of the use kodeinsoderjaschie “5-hour Energy” level of sugar and insulin in the blood were 25 per cent higher than when drinking the same drink without caffeine.
Senior research fellow Jane Shearer (Jane Shearer) is sure that the high content of caffeine in energy drinks causes the body’s response. This is alarming, because even after the pancreas Teens start to secrete insulin, a hormone, its main function is the regulation of carbohydrate metabolism, blood sugar has not decreased. Experts have suggested that it is contained in energetico caffeine is a cause of insulin resistance, as it is known, the first step in the development of diabetes mellitus type 2.
“The half-life of caffeine (the time it takes the liver to process half finished quantity – approx.) is four to six hours, causing high levels of glucose/insulin can stay most of the day,” Jane Shearer.
Although the study did not investigated the effect of long-term kodeinsoderjaschie effects of energy drinks on the body, but scientists are alarmed by the increase in the risk of diabetes type 2 in people susceptible to this disease.
Experts noted that the findings do not apply to those who consume traditionally prepared coffee, as the standard portion of the contained caffeine is lower than in energetiko, and approximately 133-178 mg. This means that a Cup of coffee a day is not only harmful, but also useful, being for most the main source of antioxidants.
