What happen to the caffeine when it is ingested, and what are its consequences? In addressing these questions, there have been many contributors spent much time to prove that caffeine has been shown to behave as an adenosine antagonist to stimulate motor activity, mood and behavior. This antagonist behavior is the basis for an increase in cholinergic and dopaminergic behavior after caffeine intake. Beside of that, the acute administration of caffeine has been reported by several laboratories to elevate brain level of serotonin (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA). This increase of serotonin may be associated with the improvement in good mood. Recent studies also show the higher caffeine intake to a lower suicide risk. In this paper, I will investigate the caffeine at a biochemical level and relate its effects on physiological behavior of human with information from the recent research.
The exact process by which it affects the body is unknown. It is suspected that caffeine affects the nervous system by altering the perception of effort and exciting the neurons responsible for contracting muscles. It may also be accountable for causing more fat and less...

Caffeine is the most popular and most widely used stimulant in the world. In Canada, the average person drinks 2.6 cups of coffee a day; that is equivalent to 949 cups of coffee a year. (Van Houtte) Caffeine is a central nervous system stimulant that improves ones attention, focus, and fatigue. When caffeine is ingested it causes your neurons to move at a faster rate, increasing alertness. (Fit Day) Caffeine also binds to the neural receptors, which blocks the adenosine, which prolongs tiredness. Caffeine is a white odorless powder that is most commonly found in coffee, tea, energy drinks, and pops. Caffeine can also be considered and ergogenic aid. Ergogenic aids are external influences that enhance/ improves ones strength, endurance, reaction time and speed of recovery. (Healthline) The three theories that make caffeine an ergogenic aid during exercise is the effect it has on the central nervous system, skeletal muscles, and metabolic changes. (Sheila G. Dean) Caffeine also has a positive effect on an individual’s health, some positive effects include: reduces risk of developing liver cancer, Parkinson’s disease, and Alzheimer’s. (Chawala) Caffeine has been proven to have positive effects on an athlete’s performance, and ones overall health.
Have you ever wondered where the most common thing we see every day comes from? Or how it came to be? After oil, coffee is found to be the most common thing traded in the entire world. Coffee is known everywhere and developed in different ways depending on where you are. According to www.pbs.org “ it is estimated that 2.25 billion cups of coffee are consumed each day worldwide.” Ever wondered why New Yorkers live a very fast paced life and never seem to rest? Its probably because they drink seven times more coffee than any other U.S. city. There are many cool facts about coffee, but the true interesting information is found where coffee comes from and how it got traded throughout the world over time. Every place has adapted coffee and has made it their own.
Caffeine, commonly found in coffee and many other beverages, and containing certain chemicals compounds leading to the constant necessity of fidgeting, jitters, sleepless hours, and health hazards as though being tormented by a hobgoblin with the irresistible sweet aroma and multiple flavors trapping you into a path, not being able to truly quit as desired or consequences attached, but is it the world’s most used legal drug addiction or something enjoyable, you decide? “The delicious chemical in caffeine is 1,3,7-trimethylxanthine”(Linn). “Caffeine is made by pressuring cooking beans with CO2 to produce the drug in powder form”(Linn). “In caffeine the consumption breakdown in Coffee is 54%, Tea it’s 43%, Food and misc it’s 3% and used as a common mood-altering drug in the world, most popular way of ingesting is through coffee”(Linn). The issue with drinking coffee is due to the fact that caffeine can cause some troubling effects like insomnia activity in the brain that prevents sleep, constant need to urinate leading to dehydration due to the lack of fluids in the body, and diarrhea causing the food right out because it accelerates the digestion in the stomach. The consumption of too much caffeine can cause damage in human health also causing an overdose leading to death. The impact in society is through how much caffeine Americans consume daily, and the effects it causes in human health and sleep patterns. Throughout the years past caffeine consumption in America has increased jarasicaly, about 90% in some form daily. “On average Americans have been known to consume 280 mg of caffeine per day or 2-3 cups of coffee”(Linn). Strangely enough, caffeine is still contained and found in decaffei...
Scrutiny of caffeine and its effects has increased dramatically in the last 20 years, due in part to an increase in consumption of caffeine. In fact, coffee consumption among young adults rose to 3.2 cups per day in 2008 from 2.4 cups per day in 2005 (Rokerya 1). For instance, in a one hour period, on Richland College’s on-campus Starbucks, the author took note of how many customers arrived and purchased a cup of coffee. Between 8:00 and 9:00 AM, there were 51 customers, implying that – especially at college - many people are dependent on coffee in the mornings. However, the results from these studies are inconclusive and often somewhat contradictory – many studies (such as that by Tetsuya Ohara et al.) show that caffeine is a great boon to

In general, people usually wonder whether the consumption of caffeine is beneficial or harmful to their health. There some benefits and risk of consuming caffeine but based on the different studies that have been conducted over the years, more importance are given to benefits of caffeine (Hensrud, 2014). According to Gunnars (2013), caffeine is good for health as it contains antioxidants and beneficial nutrients which may improve human health. Plus, Gunnars (2013) also stated that studies show that coffee drinkers have a much lower risk of several serious diseases and have proven to have some health benefits. First and foremost, caffeine help people feel less tired, increases memory and increases energy levels. This is because, when caffeine is consumed, it is absorbed into the bloodstream which then travels to the brain and caffeine blocks an inhibitory neurotransmitter in the brain. Then, the amount of other neurotransmitter such as dopamine and noradrenaline increases which leads to enhanced firing of neurons. Therefore, this improves various aspect of brain function such as memory, mood, reaction time, alertness and energy levels (Gunnars, 2013).
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 plays an enormous role in society today, from coffee to cokes to candy bars. Companies have made billions off the desire for that extra kick. Caffeine is the most widely consumed behaviorally active substance in the world making it one of the world’s most popular drugs. It’s known for the ability to stimulate the brain and central nervous system. The Chemical structure of caffeine is C8H10N4O2. Before the popular use of caffeine one can assume that people were sleepier, and less alert.
The media fails to project the negative effects of excessive caffeine intake. This literature review will illustrate how excessive caffeine consumption can be detrimental to one’s life, and how problematic caffeine use derives from conditioning by the caffeine industry. Caffeine is the single most widely consumed psychoactive substance in the United States (Einöther & Giesbrecht, 2013). According to Einöther and Giesbrecht (2013), 80% of the world’s population consumes caffeinated products every day, with coffee and tea being the primary sources. In the recent years, the demand for coffee has increased, causing the caffeine industry to create an expansion of coffee shops, new caffeinated beverages (Bailey, Saldanha, Gahche, & Dwyer, 2014), and mass-media advertising.
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. This is partly because of the amount consumed each day. Some of the antioxidants that coffee has are quinines and chlorogenic acid. It also contains trigonelline, an antibacterial compound. This is where coffee acquires its delicious aroma. Now let’s step back for a minute and just think about how much caffeine people consume. In an 8oz cup of coffee it has about 85 milligrams of caffeine. This is about double the amount that tea contains. Studies have shown that caffeine stimulates the brain and nervous system. This is where you get that energized feeling. After about the third cup, knees start to bounce, pens are clicking and people start running laps around the office. Caffeine can become addicting if you drink too much. Coffee can become that addictive habit people are unable to shake.
Caffeine has been used widely by our modern society to keep up with their hectic lifestyles. One of the many benefits of caffeine is that it increases alertness and prevents fatigue. The main source of caffeine is in the form of coffee, tea, coke and much more. However, due to its addictive characteristics, caffeine is now the most consumed drug all around the globe. Caffeine abuse results in many negative effects such as insomnia, increases blood pressure and heart rate (Pollick, 2010).
