Sugar The amount of sugar in energy drinks is excessive. Sugar equates to calories. If you are looking to lose weight and are using these drinks for hydration, you may be in for a surprise. Even in sports drinks, the sugar levels are high. For example, one common sports drink advertised for electrolyte replacement contains 280 calories in a 32 ounce bottle. An average adult running three miles in thirty minutes would burn around 360 calories. Other Ingredients A number of ingredients in energy drinks have been shown to be unhealthy or to have no value at all. One that is preva- lent (although banned by the Food and Drug Administration in the late 1980s) is ephedra, often in the form of ephedra alka- loids. Ephedra has been associated with seizures, strokes, hypertension, arrhythmias, myocardial infarctions and death. What the manufacturers claim (Table 1) and what the scientific evidence says (Table 2) generally differ. The next time you pick up an energy drink, examine what is in it and compare it with the scientifically-based benefits. You may be surprised at the results of the comparison. 50 AIRBEATMAGAZINE l JanuaryFebruary l 2012.

  • Energy Drink Consumption in Adolescents
    Energy Drink Consumption in Adolescents "Are energy drinks good for children? Raising Parent Awareness" Tag Words: Energy Drinks; caffeine; stimulant; Red Bull Authors: Rahul Vasudeva & Richard P. Moses with Julie M. Fagan Ph.D Summary Gorilla marketing and lack of regulation of energy drinks has resulted in an increase in consumption of energy drinks high in caffeine in adolescents. In fact, children below the age of 19 account for 60% of those purchasing energy drinks. On average, about 45% of patients each year admitted to an emergency room for caffeine overdose are adolescents. The hazardous effects associated with consumption of energy drinks in adolescents are discussed. These include alterations in neurological development, an increase in blood pressure and the possibility of addiction. To get the word out, answers to such questions as: are energy drinks good for children, what is a safe consumption of caffeine for adolescents; what effects do energy drinks have on children; are there healthier alternatives; and what can parents do to prevent their child from drinking energy drinks; were put on the web site Ask.com and a Parenthood website. Video Link Energy Drinks: The Effects on Adolescents: http://www.youtube.com/user/DRJULIEFAGANSTUDENTS#p/u/11/1sYWna06u9Q Part I: Energy Drinks Exposed Introduction Page 1 (RV) Energy drinks have created a huge craze in the last past decade amongst consumers. More and more people daily are consuming energy drinks in order to function optimally throughout the day. As more people begin to work longer hours, study longer and take on more responsibilities, the need for energy drinks has become an immense necessity for most people in working America.

  • Synthetic Energy Drink (Burn) Effects on Life Span of Drosophila Melanogaster
    International Journal of Scientific Research and Review ISSN NO: 2279-543X SYNTHETIC ENERGY DRINK (BURN) EFFECTS ON LIFE SPAN OF DROSOPHILA MELANOGASTER Amrutha M.R and *Krishna M.S Stress Biology Lab, Department of Studies in Zoology, University of Mysore, Manasagangotri, Mysore, Karnataka- 560006, India. Email: [email protected] , [email protected] Contact No. : +919480252830 ABSTRACT Quality and quantity of components found in the diet has a significant influence on health benefits. Different varieties of synthetic energy drinks are in use; however the quality and quantity of components found in these synthetic energy drinks are different. Present study has been undertaken in Drosophila melanogaster (D. melanogaster) to evaluate the effect of synthetic energy (Burn) on longevity. It was found that larval feeding rate was significantly greater in natural energy drinks compared to larval feeding rate in synthetic energy drinks. Further it was also noticed that flies live significantly longer in natural energy drinks than those flies lived in synthetic energy drink (Burn). Thus it was noticed from the study that consumption of synthetic energy drink (Burn) has detrimental effect on longevity in D. melanogaster. Key words: Drosophila melanogaster, Longevity, Synthetic energy drinks, Natural energy drinks. *Corresponding author M S Krishna Assisstant professor Stress biology laboratory, Department of Studies in Zoology, University of Mysore, Manasagangotri, Mysore, Karnataka- 560006, India.

  • His Mother Became Medicine: Drinking Problems, Ethical Transformation and Maternal Care in Central Uganda China Scherz and George Mpanga
    Africa 89 (1) 2019: 125–46 doi:10.1017/S0001972018000736 His mother became medicine: drinking problems, ethical transformation and maternal care in central Uganda China Scherz and George Mpanga ‘It was a sign of love.’ This unexpected interjection came from our driver, Noah, who until then had been sitting quietly on a plastic chair at a wooden coffee table drinking a tall ceramic mug of smoky sweet milk tea. ‘Other ghosts just keep quiet and kill someone, and you never know the reason why. What she did was a sign of love,’ he continued, trying to help us understand. ‘Since September [2015], Kato has not been drinking,’ Jjajja Nalunkuma said. ‘He is even looking better now. He was like an old man before … His siblings had been collecting money [to take him to a herbalist for treatment] because they were so worried about him; he has children.’ We had come to visit Jjajja Nalunkuma1 in the hope that she would be willing to tell us the story of what had happened to her grandson, Fred Kato, some nine months earlier. Jjajja Nalunkuma had been expecting us and readily agreed to retell the story that my friend Sr. Jane had first told us over Skype in February 2016 and which was the cause of our visit. Sr. Jane was among the siblings who had contributed to the project of saving the money that they would need to visit the local herbalist to buy a commonly used herbal emetic that they planned to put in Kato’s beer. This technique for inducing vomiting and a life-long aversion to the smell of alcohol is frequently employed by families looking to end a loved one’s problematic alcohol use.

DETRIMENTAL EFFECTS OF ENERGY DRINK CONSUMPTION ON ADOLESCENTS Background: In recent years the consumption of readily available energy drinks has increased significantly with young adults forming the largest part of the consumers. Commercial energy drinks are made up of mainly caffeine and many other ingredients many of which have not adequately researched and are little understood, especially excessive consumption of these combinations. Objective: The objective of this project is to enumerate the detrimental effects of energy drink consumption on adolescents, and present to youth centers through digital storytelling. The project is aimed at increasing the level of awareness of the risk associated with energy drink consumption by adolescents. Methods: The method used in the study was literature review. We searched scientific articles from the following academic databases: CINAHL, PUBMED AND SCIENCE DIRECT. Articles were also retrieved from Google scholars. The data search was carried between September 2011 and March 2012.Set of criteria were developed to guide the study to the right path. One of the criteria used is to include only the articles published in the year 1987 and above; academic databases, google scholars and books written by health professionals; articles in English language related to health effect of energy drinks or energy drink ingredients on adolescents, and the risk behaviors associated with consuming energy drinks mixed with alcohol.

  • Energy Drinks: Help, Harm, Or Hype?
    GSSI Page 1 of 11 Print Article SSE #84: Energy Drinks: Help, Harm, or Hype? Leslie Bonci, M.P.H., R.D. 08/27/2006 Sports Science Exchange 84 VOLUME 15 (2002) NUMBER 1 "ENERGY" DRINKS: HELP, HARM OR HYPE? Leslie Bonci, M.P.H., R.D. Director, Sports Medicine Nutrition Department of Orthopedic Surgery and the Center for Sports Medicine University of Pittsburgh Medical Center Nutritionist, Pittsburgh Steelers Pittsburgh, Pennsylvania KEY POINTS Many products marketed as energy drinks contain high concentrations of carbohydrate and some caffeine. Some energy drinks contain herbs, amino acids, protein, and other substances, usually in such small amounts that they are unlikely to have any noticeable effect on performance. The content of some of these products may result in inefficient absorption of fluid and nutrients from the intestine, with the possibility of gastrointestinal distress. Many energy drinks are quite costly and, because of their composition, are not suitable for use by athletes. Athletes should be educated about these products and guided towards other foods and fluids that will not pose potential risks. INTRODUCTION Athletes who train hard and frequently often complain about "energy drain" and fatigue. Because they are regularly reminded to consume adequate fluids and fuel to minimize early fatigue and to maximize performance and recovery, the concept of an "energy" drink—fluid and energy together in one bottle—is very appealing. Having more energy can improve one's capacity for work, a very desirable characteristic for all and especially for active individuals. However, in addition to good hydration and sufficient food energy, an athlete needs adequate rest, frequent meals or snacks, and optimal consumption of carbohydrates to help feel energized.
