Energy Drinks Research Essay Example for Free

Energy Drinks Research Essay Many energy drinks are found in the market and many people are consuming them without knowing the bad effects on their health, having the misconception that they help in enhancing and boosting the body energy. Ingredients: Other than the caffeine and carbohydrates energy drinks contain: B vitamins: Energy drinks contain B vitamins that exceed the daily-recommended amounts. Gingko: German pharmacological studies suggest that this herb increases blood flow to the brain and may be effective in treating depression and short-term memory loss. Guarana: An herbal stimulant popular in Brazil. The reason guarana is so stimulating is that it contains two to three times the caffeine of coffee. Carnitine: A compound generally found in animal foods thats theorized to enhance fat burning and improve endurance performance. Mechanism: Energy drinks cause many things that include: Insomnia and alertness: Most energy drinks contain caffeine and herbal stimulants that stimulate the central nervous system, giving a sense of alertness. This stimulation can cause a person who is sleepy to wake up. However, it can also prevent a person desiring to sleep from dozing off. In addition, the caffeine in energy drinks blocks the effects of adenosine, a chemical in the brain involved in sleep. This in turn activates neurons in the brain as though there were an emergency, often preventing sleep and causing insomnia. Increased heart rate: When caffeine blocks adenosine and the neurons are activated, the pituitary gland releases adrenaline. This hormone makes the heart beat faster and consuming the large dosage of caffeine found in energy drinks can lead to high blood pressure and heart palpitations. Increased blood sugar: When adrenaline is released into the system, this causes the liver to release extra sugar in to the bloodstream for energy. In addition, energy drinks contain high amounts of sugar, which can be digested easily and also used as a quick source of energy. When consumed, the body experiences a sugar high then often crashes. The sugar enters the bloodstream, provides a blast of energy and when the sugar is burned up, 30 to 45 minutes later, the body usually experiences a sugar crash. At this time feelings of dizziness, slowed reflexes and decreased performance may occur. Dehydration: Caffeine is a diuretic or a substance, which causes urination. The caffeine in energy drinks causes the kidneys to move extra fluid into the urine, which can lead to dehydration if done while sweating during exercise. The high levels of sugar in energy drinks slow the absorption of water that dilutes the sugar in the bloodstream, enhancing dehydration. Also, consuming a drink with a high sugar concentration before an athletic performance can cause gastric distress and diarrhea, resulting in dehydration. Energy: Most energy drinks contain large amounts of caffeine, which can provide a temporary energy boost. Some energy drinks contain sugar and other substances. The boost is short-lived, however, and may be accompanied by other problems. Side Effects: Energy drinks can cause inflammation in the stomach; bleeding and ulcerations in the duodenum. While consuming energy drinks alone will not damage your liver immediately, prolonged consumption of certain ingredients in popular energy drinks may have ill long-term effects on your liver. For example, many energy drinks contain herbal concentrate products like kava kava or taurine. An overabundance of either of these herbal supplements can lead to liver damage or liver failure. For example, consuming large amounts of taurine may lead to complications in individuals with type-2 diabetes. Caffeine and Guarana affect the adenosine receptors in the brain. Caffeine also cause dopamine to be released in greater amounts which makes you feel more alert and energetic and happy though it does not provide any energy.
