INTRODUCTION
Coffee has been a part of the lives of humans actively living in the society for at least 1200 years. Because of this it is also known as the second most valuable produce worldwide next to oil, which has become a regular part of the daily life of people worldwide (Bonita, Mandrano, Shuta & Vinson, 2007 as cited by Bae, Park, Im, & Song, 2014). One of its best known constituents is caffeine, but it also contains carbohydrates, lipids, nitrogenous compounds, vitamins, minerals, alkaloids and phenolic compounds (Bonita et al., 2007 as cited by Bae et al., 2014). As presented by Cornelis & El-Sohemy (2007) in their work, the act of drinking coffee is an impetus which motivates socialization in social activities or can even

The intensity of a person’s alertness is different throughout the 24-hour day according to Jensen (2015). There are means to quantify a person’s alertness using the Optalert Alertness Monitoring System or OAMS and from this we can apply the results into both Johns Drowsiness Scale (JDS) which is an objective scale and the Karolinska Scale, compared to JDS this is subjective, to further understand the accumulated results from OAMS (Aidman, Chadunow, Johnson & Reece, 2015).
This study intends to recognize the value of the constituents of coffee by analyzing the effects and functions it has on second year biology students. It is tantamount to be enlightened about the effects of coffee since it is consumed by most of students and for working adults. Knowing the effects of caffeine on the human bodily functions could prove to be advantageous to its consumers based from past research and

The consumers will be able to know exactly the effect and role of coffee in relation to alertness. This study will also provide information about the individual regarding the amount of consumption and number of times of consumption. This is relevant, especially to the youth, because the youth are primary consumers of coffee as they always consume coffee in order to accomplish tasks related to academics and knowing its effects on alertness and health is beneficial for the students as they can adjust their levels of consumption or look for alternatives base from the results of this
The objective of this experiment was to perform extraction. This is a separation and purification technique, based on different solubility of compounds in immiscible solvent mixtures. Extraction is conducted by shaking the solution with the solvent, until two layers are formed. One layer can then be separated from the other. If the separation does not happen in one try, multiple attempts may be needed.
Caffeine, a central nervous system stimulant, is the main psychoactive ingredient in energy drinks, which enhances alertness and mood, and counteracts symptoms of sleep. There is no doubt ...
Caffeine is a mild stimulant that occurs naturally in at least 63 plant species. Caffeine can be found in the leaves, stems, seeds, and roots of these various plants. Caffeine is part of the methylxanthine family. It consists of a xanthine molecule with three methyl groups attached to it. Caffeine can be found in many products like sodas, tea, and coffee, but it also occurs in several other products such as prescription medications, diuretics, and pain relievers. Caffeine’s widespread use and popularity have caused many people to view the substance as an addictive drug. Thus making caffeine the most inexpensive and readily available drug known to man. Then on the other hand there are people who view caffeine as a helpful stimulant that increases the individual’s concentration and awareness as well as many other physical traits. The important thing to remember is that caffeine’s affects vary based on the person, the amount ingested, the frequency of consumption, and individual metabolism.

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.
In the United States, coffee is the second largest import (Roosevelt, 2004). Furthermore, the United States, consumes one-fifth of all the worlds¡¦ coffee (Global Exchange, 2004). The present industry is expanding. It is estimated that North America¡¦s sector will reach saturation levels within 5 year (Datamonitor. n.d.). According to National Coffee Association (NCA), 8 out of 10 Americans consume coffee. In addition, it is estimated that half of the American population drinks coffee daily. The international market remains highly competitive. It is estimated that 3,300 cups of coffee are consumed every second of the day worldwide (Ecomall, n.d.). The latest trends included dual drinkers, an increase in senior citizens...
As the vast majority of Americans are addicted to caffeine, studies show that the effects during post-consumption, can be positive or negative depending on the amount and frequency of caffeine intake. As the demand for caffeine has increased, the caffeine industry has increased its amount of marketing and establishments to help aid this demand. Caffeine addiction can lead to serious health and physiological detriments. It is evident that the primary reason for consumption of caffeinated beverages is due to positive effects, such as alertness. The media has an abundance of marketing to continue to illustrate this main effect.
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). If nicotine was as acceptable to people as caffeine is, cigarettes would be more heavily used and might not even have a law on how old you should be before you smoke. One study showed that 75-98% percent of youth intake at least one beverage containing caffeine each day. 31% of the same youth consume 2 or more beverages containing caffeine daily (Morgan, Stults, Zabmick, NFS, 2008). If caffeine wasn’t so socially acceptable, these numbers would be drastically different. When youth were polled on when they consumed the most caffeine during the week, the results showed that after midday Wednesday, the consuming of caffeine begins to rise. Sometime on Saturday is when it reaches its height, and begins to go back down (Pollack, Bright, 2008). There are many opinions on why this is happening, such as stress relating to school, getting through the week, or less sleep during the week. When scientist Hoidrup lo...
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.
The following study will examine and provide research methods, results and conclusions about college students who consume caffeine, energy drinks, alcohol or both to get an energy boost for one reason or another. Coffee, which used to be the highlight of boosting energy and staying up late nights to complete homework assignments or study, has taken a fall in the 20th century. The study will also point out the effects of the energy drinks and alcohol and the harm and health concerns that contribute to the students behaviors when consumed. The first study examines energy drinks and alcohol among college students and the fact that more students are consuming the product. The study is a web-based questionnaire.
Open with Impact: How much coffee do you drink? How is that cup of coffee affecting your brain, thinking skills, alertness, sleep, and overall health?
Millions of Americans begin each day by consuming the most widely used drug in the United States: Caffeine. Over 90% of United States adults consume caffeinated food or beverages on a daily basis and over 50% take more than the recommended amount. Our innocent daily ritual can turn into an addiction for some because many do not realize that caffeine is even a drug let alone the effects it can have on their bodies. Its use it becoming more and more prominent in our society. It’s not uncommon to walk outside and see a Starbucks or coffee shop on each corner. Innovative foods are coming out infused with coffee, and energy drinks are being pushed at every angle. Caffeine to many is a necessity to wake up in the morning and for others to stay up all night. This is dangerous because people are not only becoming more and more dependent on coffee drinks and energy drinks but they are beginning to ingest more of it each day and are now mixing it with other drugs that can be life threatening. Proper knowledge is important when taking any drug including one that the FDA considers to be a safe multi-purpose food substance and education is the key.
Teenagers who are used to consuming in excess of six cups of coffee during the past month are more likely to use alcohol or tobacco. This is according to a study that was done on more than five thousand seventh graders. Energy drinks combined with alcohol comes with dire potential for abuse and harm. These uses lead to diminished intensity responses that in turn lead to tolerance. As a result, alcohol of higher does will be required for attaining the initial effect ( Miller 74). The consumption of caffeine by children and teenagers should not go beyond 100mg and 2.5mg/kg in a day. For instance, 8 oz of Red Bull has 77 mg of caffeine, 2.2 mg/kg for a 35-kg preteen and 1.1mg/kg for 70-kg male. Adults and teenagers experience different effects of caffeine. While it is true that there is no clear line of separation for the effects, boys exhibit more speech rates, motor activity and reduced times of reaction as compared to men. On the other hand, blood pressure effects are similar for both adults and teenagers. Although caffeine can improve attention, it also contributes to disturbance of sleep and increase in pressure among the teenagers. When teenagers who are used to energy drinks consumption abandons their behavior, their reaction time rises as the attention decreases. On the other hand, reaction time decreases with every increase in the dosage of caffeine among teenagers. Habitual caffeine
Caffeine is one of the most widely consumed stimulants in the world (Evans and Griffiths, 1999). Caffeine in itself comes in many forms, such as coffee, tea, soda, energy drinks and other supplements that are all meant to aid in energy depletion and focus. Caffeine’s practicality and ease of consumption have lent itself to becoming a well-studied stimulant in regards to how it impacts the health of users after extended periods of use. Caffeine is considered an addictive substance with around 100 mg a day leading to dependency (Evans and Griffiths, 1999). In addition to that many substances in which caffeine is consumed have been seen in conjunction with obesity and other health problems (O’Connor, Yang, & Nicklas, 2006). Studies on caffeine
The coffee and the tea are the two most popular and consumed beverage after water. Centuries before, coffee and tea have been less in amount than food, but they were much frequently and were only in pharmacy available. In 16-the century British Doctors described the health benefits of coffee as “help digestion, accelerate the mind, makes the heart light, and relieves cough and headache.” The now days statistics shows that coffee is mostly consumed in the USA, in the countries of South America and in North of Europe. Tea is more preferable in Asia and in Australia. The popularity is due to the effects of caffeine, an ingredient in the both plants. Caffeine has several effects in our body.
