A. Attention Getter- Do you guys know that Caffeine is the most widely used psycho active chemical in the world? Caffeine is a central nervous system stimulant substance found in foods and beverages such as coffee, tea, soft drinks, energy drinks and chocolates which helps to restore mental alertness or wakefulness during fatigue or drowsiness and improve concentration and focus. According, to the stats published by Health Research Funding Organization, The United States is the country with the highest amount of caffeine consumption (971 tons) followed by Brazil (969 tons). (HRFnd)
B. Significance- Caffeine is a growing trend in our society, specially among the younger crowd like us. European and North American statistics report that 90% of adults consume caffeine on a daily basis, with an average intake of 227 mg. (Persad, Leeana Aarthi Bagwath). Although it has an sufficient amount of properties to assist with maintaining a high level of energy, caffeine is extremely addictive and an excessive amount of consumption can be physically damaging. (HRFnd)
C. Credibility- I, myself used to consume a lot of caffeinated drinks. When, I worked as a bar back few years ago, I had to work late night busy weekend shifts. So one night I consumed about 8, 12o.z red bull energy drink as I was feeling tired because of the amount of work I had to do that night. But, it was not a pleasant experience afterwards at all. Consuming that amount of caffeine obviously gave me extra energy boost while working but after work my body became more tired, my heart rate spiked and I couldn’t go to sleep until 6 or 7 am in the morning.
D. Thesis- Learning about the effects that caffeine can do to our body will help us be more aware of our consumption, so that we can maintain a healthier lifestyle.
