Energy drinks - who needs them?
Consumption of energy drinks is growing all the time. What kind of effects do energy drinks really have? Who needs them?
Energy drinks are suitable as sports drinks.
False. Energy drinks contain caffeine and taurine, which are diuretics, that is, they remove liquid and salts, such as sodium. This can impair performance in a long-lasting stress. Energy drinks as a usual sports drink has too much carbohydrates (10-15 g / dl), and their light versions do not have any carbohydrates. In addition, the right sports drinks include sweat-out salts.
In some studies, energy drinks have been found to improve reaction time and alertness as well as aerobic performance. Energy drink can be enjoyed, for example, before gym workouts, which may improve performance, but as a real sports drink it is a bad option.
Two cans of energy drinks per day is too much.
Caffeine-sensitive even cans can cause restlessness, heartburn and insomnia. Especially caffeine sensitive, it is best to avoid energy drinks.
Any excessive caffeine intake may cause unpleasant symptoms such as palpitations, nervousness and abdominal distress. But the effects are very individual. An excessive single dose of caffeine is considered to be 600-1000 mg, which accumulates over two liters of energy drink.
There is no information on the safety of the long-term use of energy drinks. However, use is very common and no serious adverse effects have been demonstrated.
Continuous use of energy drinks results in dependence and discontinuation of withdrawal symptoms.
True. The caffeine contained in energy drinks is more easily addictive than the same amount of caffeine as a coffee. The coffee contains ingredients that reduce the onset of caffeine dependence. The light versions of energy drinks do not differ from the normal versions of energy drinks.
One cup of coffee with sugar gives as much power as energy drink.
False. In studies, pure caffeine has been found to increase the performance more than the same amount of caffeine in a cup of coffee. The taurine contained in energy drinks may slightly enhance the effect of caffeine.
The amount of caffeine contained in coffee cup varies between 50 and 150 milligrams. Energy drinks contain caffeine about the same amount as a cup of coffee.
Children should not be given energy drinks.
True. Because of its high caffeine content, energy drinks are not recommended for children, expectant mothers or caffeine-sensitive people. Because of the high amount of caffeine contained in energy drinks, packaging and labeling are subject to caution and caffeine labeling as well as recommendations for daily use.
Energy drinks contain stimulant compounds such as caffeine, guarana or taurine. In addition, they have quite a lot of B vitamins.
True. Caffeine has a stimulant effect that can be enhanced by taurine, but there is no scientific evidence for the stimulating effect of other substances.
Guarana, glucuronolactone, inositol and pantothenic acid, vitamin B5, niacin, vitamin B3 and other vitamin B vitamins have also been added to many energy drinks. Beverages are based on carbonated water and generally contain sucrose, glucose or maltodextrin. In lighter versions of energy drinks, carbohydrates have been replaced by energy-free artificial sweeteners such as aspartame, acesulfame K or sucralose.
Guarana of energy drinks is the real miracle material: it improves performance, burns fat, prevents diseases, increases potency and refreshes brain activity.
False. Guarana is a caffeine-containing plant, whose addition to energy drinks has no basis other than acting as a source of caffeine. There is no scientific evidence for Guarana's other alleged effects.
Caffeine, including guarana, stimulates and influences favorably, including reaction time, concentration ability, and near memory. It has been shown to have a positive effect on physical endurance. Caffeine may also enhance anaerobic performance.
Energy drinks contain taurine which, together with alcohol, can cause poisoning.
False. The interactions between the substances contained in energy drinks and alcohol have been studied in a number of studies. No adverse drug interactions have been observed. Energy drinks, however, increase the amount of dehydration caused by alcohol consumption, so energy drinks should be reasonably enjoyed with alcohol.
Taurine's effects on physical performance have been studied scarcely, but it appears to enhance the effect of improving the caffeine's performance. Taurine has also been found to have a positive effect on the mood.
Taurine is indispensable only in infants. It is also dietary, for example, fish, meat and crustaceans, with an average intake of about 100 mg per day. One pack of energy drinks may contain up to 2,000 mg of taurine.
Energy drinks are as damaging to teeth as soft drinks.
True. Energy drinks have harmful carbohydrates (sugars) harmful to the teeth roughly the same as in soft drinks. Energy drinks are also as acidic as soft drinks.
Energy drinks have more energy, ie sugar than other soft drinks.
False. Energy drinks have about the same amount of energy as soft drinks, and they also have lighter versions. Invoking non-energy drinks to energy drinks is misleading. Energy drinks are, in this case, beverages containing stimulant substances, which, according to manufacturers, increase the user's energy.
Energy drink helps to stay up and in control.
True. Energy drink stimulates and relocates the need for sleep momentarily.
