But please with sugar: Limos in the light version make the alcohol rise more quickly. Image: Thinkstock
Reading aloud Anyone who likes mixed drinks such as whiskey-cola or vodka-lemon should keep their fingers off the light versions of the soda pop portions. If you have to blow after that, you will experience its blue miracle in the low-calorie limos: In combination with light drinks alcohol goes much faster into the blood than the same combination with the sugary variant - without you noticing. That's what US researchers have discovered. Their conclusion: Although light saves calories, but could cost money - or even the driver's license. There have been repeated reports from bar operators, after which mixed drinks with light lemonades affect the guests faster than the same drinks with the normal soda. A previous study also proved that light fans have an average higher blood alcohol level than those who drink long drinks with sugary sodas. These observations, which come from the "wild" as it were, inspired them to their current study, reports the psychologist Cecile Marczinski of the Northern Kentucky University. Their goal was to systematically test the previously anecdotal reports and tests in the laboratory.

For this she and her colleague Amy Stamates invited 16 volunteers - eight men and eight women - to the university for three different drinking tests each. Each of them received one of three drinks at each test and was then asked to state how he felt, whether he felt the effect of the alcohol and how he would assess his ability to drive. An alcohol determination in the breath followed, as well as a reaction test on the computer. The drinks were a mixture of vodka and a citrus lemonade, the latter once in the sugary version and once in the light version, which contained the sweetener aspartame. The third was an alcohol-free placebo drink.

Normal Limo: Driving allowed, Light version: Driving prohibited

Result: Although the subjects felt the same after sugary and artificially sweetened long drink, they did worse after the light version in the reaction test. In addition, the concentration of alcohol in their breath and thus in the blood was higher: in the normal lemonade, the researchers measured a value of 0.77 and the Light-Limo ​​of 0.91 per thousand - despite the exact same alcohol content of the drinks. In the former, driving at a limit of 0.8 per thousand, as it prevails in the US, would be legal, but not more in the US, the researchers emphasize. display

However, they find it particularly problematic that the test participants did not feel the difference. This can lead to greater problems in assessing their own driving ability and increase the risk of an accident on the road, they admonish. However, what causes the measured difference, they can not say yet. The digestive tract may treat the sugary soda more like a meal, they speculate. And one knows that food delay the absorption of alcohol into the blood. Thus, the result of the study would be more attributable to a dampening effect of the sugar than to any kind of accelerating effect of the sweetener, they conclude.
