Edari energetikoak eta haien eraginak

Abstract

Energy drinks are caffeine containing drinks, and are commercialized to reduce fatigue, increase concentration and improve physical and mental performance. Depending on the type of drink, the amount of caffeine can vary from 50 mg to 505 mg. The consumption of these drinks has increased significantly in recent years due to its free sale and different marketing campaigns. When advertised as food supplements, some countries are not obligated to indicate the exact amount of caffeine or to warn of the possible risk of its consumption, which increases the possibilities of caffeine poisoning. As well as caffeine, energy drinks are also compounded of taurine, carbohydrates, vitamins, minerals and other bioactive substances, although caffeine is the main responsible for most of the effects that these drinks produce in our organism. Caffeine is the most consumed psychostimulant in the world and although in the past it was related to arrythmias, hypertension, anxiety and insomnia, there are many clinical trials that deny the above statements. Finally, a maximum amount of caffeine per day has been established for the consumption of children, adolescents and pregnant women, as these are considered sensitive groups. Several studies have shown that a consumption below these maximums doesn’t produce any risk. In adults, there is no evidence to forbid energy drinks consumption, but in children it should not be the source of caffeine, as several studies show that this is related to different complications.
