Caffeinated drinks can cause problems controlling glucose in adolescents
04 Dec 15
Study showed that consumption of caffeinated drinks caused increase of glucose and insulin levels over several hours.
Adolescents who consume caffeinated energy drinks may experience an increase of insulin levels and problems with blood sugar control. This is suggested in a Canadian study presented at the "World Diabetes Congress" of the International Federation in Vancouver (Canada). These types of drinks may therefore contribute to increased metabolic risk.
Researchers at the University of Calgary included 20 adolescents (ages 13 to 19, and an equal number of males and females) in their experiment. They were asked to drink a caffeinated and a decaffeinated energy drink (both sugar-free) while fasting. Forty minutes later, they underwent a standard two-hour oral glucose test. Blood samples were collected before consuming the drink, at the beginning of the test and again at 30, 45, 60, 90 and 120 minutes.
Findings showed that blood glucose levels increased by 25 per cent during the two-hour measurement period after ingestion of the caffeinated energy drink when compared with the control group. The increase was accompanied by a 26 per cent increase in levels of insulin. Since the half-life of caffeine is four to six hours, the researchers assume that consumption of caffeine could affect glucose regulation for several hours after ingestion.
Study author Jane Shearer voiced her concern saying "elevated glucose and insulin responses may contribute to increased metabolic risk including type 2 diabetes and cardiovascular disease in susceptible individuals later in life".

Poster's note - "After several damaging episodes with seizures accompanied by fractures I gave up consumption of all caffeine containing beverages ...I think this has helped me to control Hypos as I haven't experienced a repeat for more than 10 years". GW
09/12/2015 Addendum - I should have said that I have never again experienced loss of consciousness with concomitant seizure; but I do still get milder hypo's if I exercise too soon after eating - the two hour period seems to be critical. GW
