An energydrink is a beverage that contains ingredients to increase the drinker’s energy.They may or may not be carbonated. Most of the popular energy drinks containingredients such as caffeine, B vitamins, and various types of sugars whilesome may contain certain ingredients like taurine, glucuronolactone, guarana,ginseng, ginkgo biloba extract and L-carnitine. Caffeine stimulates neurons inthe brain to keep us alert, releasing adrenaline, which sends a signal to theliver to pump more glucose into the bloodstream.
With more glucose in thebloodstream and body, our brain is tricked into believing that we have moreenergy than we really do. Adrenaline makes heart beats faster and dilates theeyes. Energy drinks can cause some people to miss sleep since caffeine blocksthe effects of adenosine, a brain chemical that helps us sleep and that canlead to insomnia, interfering with the ability to perform concentration heavytasks. Consuming too much caffeine can produce a diuretic effect, which is alsoa cause of dehydration, anxiety, and irritability from too much of thestimulant. Also panic attacks and migraine headaches can occur from thecaffeine withdrawal. Taurine, an amino acid, regulates skeletal musclecontraction and may reduce exercise-induced damage thus encouraging improvedathletic performance. Also normal people who drink many energy drinks will haveincreased heart rates up to an hour later.
People with certain heart problemscan undergo cardiac arrest after having too many energy drinks. There is a studywhich shows the connection between energy drinks and cardiac problems. Anothercomponent, glucuronolactone claims to favor the body’s natural defensemechanism but little research has been done and so it is still unknown whetherthis compound is harmful or beneficial .B vitamins are water-soluble vitaminsrequired as coenzymes for proper cell function.
Because of the large amounts ofsugar in these energy drinks, B vitamins are needed to transform those sugarsinto energy. Guarana is a tropical fruit rich in caffeine and it is used toincrease energy. However, since guarana contains caffeine adding it willincrease the overall amount of caffeine in the energy drinks. Ginseng, apopular herb, is also included in some energy drinks. Like guarana, the amountof ginseng in the energy drinks is not enough to cause a striking effect.Ginkgo biloba extract has been reported to have antioxidant properties.
However, no well-conducted research has shown that it has important clinicaleffects on healthy or ill persons. L-Carnitine, a compound made in the liverand kidneys, increases metabolism. It also increases maximal oxygen consumptionand lower the respiratory quotient, increasing lipid metabolism and affectsrecovery from exercise stress. Sugars are the basic currency of energy in thebody, with glucose being the main carbohydrate that can easily be oxidized bythe muscles for energy synthesis.
However, long-term exposure of the body toexcesses of simple sugars is associated with obesity and insulin resistance. Overtime, cells become unable to secrete sufficient insulin to maintain normalblood glucose levels eventually wearing out the insulin-producing cells of thepancreas, which leads to type 2 diabetes. Heavily consuming these energy drinksmay result in liver or nerve injury, various cardiovascular problems, seizuresand ultimately death. While energy drinks may provide short and rapid effects,they are not actually good for our body in the long run.
