Red Bull and Co: What a can of energy drink does to the body
Energy drinks like Red Bull are becoming increasingly popular. Not only young people want to keep awake with it. They are also often consumed mixed with alcoholic beverages. Experts have long warned of the health risks posed by energy drinks. A website now shows what effects a can already has on the body.

Blind to large amounts of Red Bull
For years, doctors and nutrition experts have been warning that energy drinks are dangerous to your health. After high consumption, this can lead to a rapid heart rate or high blood pressure. Only recently has there been a case of a young woman from Northern Ireland experiencing temporary vision loss and massive intracranial pressure after consuming 28 cans of Red Bull. But much smaller quantities also have an enormous impact. A website now shows what the consumption of a 250 milliliter can does in our body.

What a can of energy drink can do
A blogger recently showed what happens in the body after drinking a can of cola. Now the website "" adds and explains in a graphic what effects the consumption of a can of an energy drink like Red Bull has. The information comes from Red Bull, LiveStrong, Starbucks, Medical Study and the U.S. authorities National Health Service (NHS) and Food and Drug Administration (FDA).

More alert and focused
About ten minutes after drinking an energy drink, the body has absorbed around 80 milligrams of caffeine and 27.5 grams of sugar. This corresponds approximately to the amount of nine sugar cubes. Blood pressure and pulse increase due to the caffeine. The concentration increases within the first 15 to 45 minutes - depending on how fast you drink. After around 20 minutes, you feel more awake and more focused or stimulated. The blood sugar level is then at its peak.

Caffeine intoxication quickly subsides
About 40 minutes after emptying the can, the body has completely absorbed the caffeine. More sugar is pumped into the bloodstream by the liver, and blood pressure continues to rise. The messenger substance dopamine is released by the brain, the reward center is stimulated and after about an hour there is a “sugar crash”. Then the short caffeine high dies down again. The sugar is processed by the body and partly converted into fat. As a result, you get tired again, feel irritated or nervous.

Consume only in moderation
Half of the caffeine is broken down after about five to six hours and all of it after twelve to 24 hours. Those who regularly consume such drinks can then experience withdrawal symptoms. Headaches, restlessness, nervousness or constipation may occur. The operators of the website come to the conclusion that energy drinks should only be enjoyed in moderation, if at all. The Federal Office for Risk Assessment (BfR) could probably also sign that. On its website, the Office warns in particular of the dangers of combining alcohol and energy drinks. According to the experts, this mixture could lead to cardiac arrhythmias. In addition, the high sugar content is problematic. The BfR also says that you should not consume more than 200 milligrams of caffeine a day. However, many regularly exceed this amount. Young people in particular consume too much caffeine, as a study by the European Food Safety Authority EFSA recently showed. (ad)
