While the average coffee lover drinks 23 gallons of coffee every year, a tea enthusiast would generally drink 10.3 gallons a year. With this amount being consumed each year, what effect does it have on the human body? Coffee is the first thing that people associate with instant energy on a groggy morning. “In the U.S., coffee is king of beverages” (Reinke) Research has been done that has named coffee as an addiction to the people who consume large quantities of it. Coffee was named the top source of antioxidants.
Caffeine, also known as methyltheobromine, is a central nervous system stimulant that humans consume on a daily basis. Found in coffee, tea, and other caffeinated beverages, caffeine has many side effects. While caffeine can make the consumer feel more alert, there are health concerns such as dependence and hypertension. Caffeine has a specific chemical structure that enables it to be absorbed easily into the stomach and intestines. It is derived from purines, and is hydrophobic, which allows easy passage through cell membranes.
Coffee and Energy Drinks both are common sources of a “caffeine buzz” in the early morning or late night to awaken the body and brain. The caffeine stimulates the central nerve system. Millions of Americans are looking to cut out about 90 minutes of sleep or more and compensate it with caffeine, therefore increasing the need for Coffee and Energy Drinks. Though drinking one cup of Joe after the other may seem like no big deal and easy to handle, the recommended intake of caffeine is approx. 400 mg. One 16 oz.
Caffeine has many negative effects on humans, such as increased heart rate (Lane, J.D., 2002), depression (Goldstein, 2008), and addiction to this “drug.” You may be asking yourself, “What is caffeine?” Well, caffeine is actually a stimulant (Barone, Roberts, 2008) that is found in beverages such as tea, coffee, and soft drinks. In fact, caffeine is the highest grossing and most used stimulant in the United States (Barone, Roberts, 2008). It is estimated that 85% of adults living in the United States consume caffeine on a daily basis (Barone, Roberts, 2008). That means for every 100 adults, 85 of them have had a drink that contained caffeine on any given day. One reason caffeine is so widely available compared to other stimulants is because caffeine is socially acceptable (Brice, Smith, Sutherland, Chistopher, Childs, deWit, 2008).
When a person drinks coffee, the caffeine is absorbed into the bloodstream and then travels to the brain where it blocks an inhibitory neurotransmitter called Adenosine. When this happens, the amount of other neurotransmitters actually increases. “You usually drink coffee when you are sleep-deprived, right? Well, that much-needed jolt not only keeps you awake, it makes you sharper. CNN reports that coffee allows your brain to work in a much more efficient and smarter way.
For a lot of people drinking coffee has to be on their daily to-do list. While a fluid ounce of typical coffee has 18 milligrams of caffeine, a fluid ounce of Rockstar or Monster only pack 10 milligrams of caffeine. I believe we should all be concerned on the amount of sugar or caffeine that our favorite daily products contain. Clearly, not much research has been done on energy drinks, coffee on the other hand has been researched or the past 100 years. Just like anything else,
INTRODUCTION ‘Caffeine is a naturally occurring compound also called Trimethylxanthine.’ (Cavellier, 2014). Caffeine is also a stimulant drug, a drug, which temporarily accelerates various vital processes. Caffeine is commonly found in beverages such as soft drinks and coffee, but it can also be found in coco beans and many other plants. The Kola nuts, for examples are used to, produce the Coca Cola flavour and is also used and found in medicines. Numerous people rely on caffeine as an effective way to "wake up" in the morning however, studies have shown that it is addictive, can cause depression and have pregnancy risks.
It is often used to stay awake longer and late into the night. Many people feel as though they “cannot function” in the morning without a cup of coffee to provide caffeine and the boost it gives them. Caffeine is an addictive drug. It operates using the same mechanisms that amphetamines, cocaine, and heroin use to stimulate the brain. Caffeine effects are more mild than amphetamines, cocaine, and heroin, but it is manipulating the same channels, and that is one of the things that gives caffeine its addictive qualities.
Secondly, caffeine may lower the risk of type II diabetes in humans. Particularly, type II diabetes is caused by high blood sugars in the context of insulin resistance or the failure to secrete insulin. According to Gunnars (2013), studies illustrate that people who consume caffeine have a 23-50% lower risk of getting type II diabetes while one study showed a reduction as high as 67%. In addition, each daily cup of coffee was associated with a 7% reduced risk of developing type II diabetes based on a massive review that looked at data from 18 studies with a sum of 457 922 individuals... ... middle of paper ... ...unnars, 2013). Lastly, caffeine could drastically improve physical performance.
It is also a stimulant, meaning it has the ability to increase activity.

Excessive amounts of caffeine are considered over 833 milligrams which compares to ten eight ounce cups of coffee (Dugdale). If the amount of caffeine taken is controlled, the negative effects of caffeine will not be experienced. Even though caffeine does produce some negative effects, its benefits are numerable, especially for college students.
