Can energy drinks cause long-term damage?
Energy drinks: Serious side effects possible
Energy drinks promise higher performance and better concentration. The sweet drinks are particularly popular with young people: According to a survey, every fifth person between the ages of 10 and 16 regularly drinks energy drinks. But those who drink the stimulating drinks frequently and in large quantities increase their risk of a heart attack or even sudden cardiac death. Several deaths associated with energy drinks are already known from the USA.
Additives in energy drinks: maximum dose reached quickly
What distinguishes energy drinks from other sugary drinks is a mixture of additives - mainly caffeine, taurine, vitamin B, L-carnitine or ginseng extract. Caffeine and taurine are said to increase alertness and performance. But with energy drinks you quickly ingest too high amounts of these substances.
The European Food Safety Authority (EFSA) considers a maximum of three milligrams per kilogram of body weight per day for caffeine to be harmless. According to this, a young person weighing 50 kilograms exceeds his daily limit with just two small doses of an energy drink.
Side effects of caffeine: danger to the heart and circulation
Too much caffeine can have dramatic side effects:
- shortness of breath
- sleep disorders
- Muscle tremors
- epileptic attacks
- Cardiac arrhythmias
Energy drinks can put a strain on the cardiovascular system, especially in combination with alcohol. Because alcohol and caffeine increase the heart rate. The caffeine ensures that the body can tolerate more alcohol. If physical exercise such as dancing or sports is added, the heart is quickly overwhelmed. In the worst case, this can lead to a heart attack.
tip: At www.checkdeinedosis.de the Federal Ministry of Food and Agriculture (BMEL) provides a caffeine calculator that anyone can use to calculate whether the amount of caffeine consumed is acceptable.
Combination of active ingredients puts a strain on the heart
A study commissioned by the Federal Institute for Risk Assessment has shown: The combination of several active ingredients in energy drinks puts more strain on the heart than caffeine alone. In the study participants who had drunk one liter of the stimulant mix, the blood pressure rose more than in participants who had only consumed caffeine. An important ECG value, the QT time, also changed - a sign that cardiac arrhythmias can occur.
Who should do without energy drinks
Experts advise against the following consumers of energy drinks:
- People with cardiovascular diseases
- People taking ADHD drugs, sleeping pills, or sedatives
- People who are sensitive to caffeine
Do B vitamins damage the liver?
There is ample evidence that consuming more energy drinks can also damage the liver. This is probably due to the addition of B vitamins, which in high concentrations can lead to liver damage.
Lots of sugar in energy drinks
A small can of energy drink contains 54 grams of sugar. That is more than twice the maximum daily dose recommended by the World Health Organization (WHO). A permanently increased consumption of the drinks can also lead to obesity and diabetes.
Sales ban requested
Despite the health risks, the manufacturers of energy drinks only have to warn against excessive consumption in the small print on the can: "Increased caffeine content. Not recommended for children and pregnant or breastfeeding women."
Consumer advocates and the WHO are calling for a sales ban to children and young people. The Federal Ministry of Food has so far relied on education and has commissioned information material for schools, for example.
