Individual Differences Affecting Caffeine Intake Essays

About 80% of American adults consume 200 mg of caffeine a day. “A 12-oz. (tall) coffee from Starbucks will run you about 260 mg, while a 14-oz. Dunkin’ Donuts coffee contains 178 mg.” The daily intake of caffeine differed between products; one should always check the amount before consumption. There are no limits on how many energy drinks a person can purchase, which make it easy to abuse. Especially in younger children the addiction rate outstandingly high. Which may lead to other drug usage in the future and the committal dependence on stronger drugs.

This article discusses the affects caffeine has on several aspects of human health. These included toxicity, cardiovascular effects (arrhythmia, heart rate, cholesterol and BP), bone/calcium balance, behavior, and reproductive and developmental effects. It also discussing the affect caffeine intake has on children and reproductive-aged women.

Caffeine is the most widely used drug in the world and the consumption in humans is constantly growing. Caffeine is found in a lot of the consumables that are ingested on a daily basis (Nawrot P., et al). Research claims that an appropriate and healthy daily intake of caffeine is approximately 400 milligrams. Research also shows that a large amount of caffeine intake a day has been proven to lead to several cardiovascular

Caffeine is a psychoactive drug and potentially deadly in large amounts, especially for adolescents (Hershorin, Lipschulz, Schaechter & Seifert, 2011). Caffeine is one the most common energy drink ingredients and one of the most widely consumed substances in the world. According to the National Institutes of Health (NIH), caffeine is a chemical stimulant compound found in various plants that acts as a central nervous system stimulant. Caffeine is produced naturally and artificially. Caffeine is found mainly in coffee, tea, soda, chocolate, energy drinks and some over-the-counter medications. Due to the increasing demands placed on teenagers today, caffeine is becoming more prevalent in adolescents. While the American Academy of Pediatrics recommends children have no more than 100 mg of caffeine a day due to unknown medical conditions, the fact a teenager’s brain is still in a developmental stage, and the importance sleep plays in the developing brain. Table 1, shows the amount of caffeine for the energy drinks in this report. (Note-this does not include the caffeine from blend ingredients)

Symptoms that follow caffeine consumption are: anxiety, panic attacks, increased heart palpitations, trembling, stress, heartburn, and the deprivation of sleep (Driedger, Doyle par 2). Over time these symptoms can become more severe and eventually will become a major disturbance in one’s life. The anxiety that comes from this can be especially harmful to those who suffer from anxiety disorders, such as GAD-General Anxiety Disorder and Panic Disorder as the caffeine can stimulate a panic attack (Human par 3). The most apparent concern of caffeine consumption, is its effects on teen life. Dr. Jim Lane, a researcher at Duke University stated, “Teens are chronically sleep deprived. Caffeine use might be a consequence of that, and also a cause. Drinking coffee could lead to sleep-onset insomnia, or a delay in going to bed, that contributes to sleep deprivation” (Teens par 7). This shows that as the caffeine trend among teens continue, the link to teen sleep deprivation strengthens. Not only does it prevent the continuation of sleep, but also the process of even falling asleep is delayed. The more deprived of sleep these

2. Diabetes, Researchers at Duke University Medical Center found that consumption of caffeine raised the average daily sugar levels by 8 per cent.

Even though I do not possess a caffeine produced disease, I have experienced the consequences of drinking high amounts of caffeine which includes anxiety, insomnia, gastritis, colitis, mild tremors, and irritability. Although small quantities of caffeine may not substantially cause serious problems, if consumed in high quantities (>400mg.), it might worse the conditions of an anxiety disorder, diarrhea, bipolar disorder, bleeding disorders, heart conditions, diabetes, glaucoma, osteoporosis, epilepsy, irritable bowel syndrome, and high blood pressure (webmd, 2009). In addition to the consequences of caffeine mentioned above, new studies have linked caffeine to psychotic symptoms (Grimson, 2011). At the moment, I do not suffer any of the diseases previously mentioned, but I do have a family history of diabetes, depression, and anxiety disorders. Thus, the predisposition to any of the risks of a high caffeine intake increases. In summary, the consequences of consuming high doses of caffeine vary from person to person, and it may elicit different effects, which may range from a mild change of mood to a complex psychotic break; therefore I considered quitting caffeine an optimum choice for a healthier

The primary literature article is titled, Dose–response study of caffeine effects on cerebral functional activity with a specific focus on dependence. This article consists of many parts including an abstract, introduction, materials and methods, and results. The articles aim is to explain the physiological functions of caffeine and how it affects the brain. The language used in this article is very specific and scientific. It consists of very precise word choice and both quantitative and qualitative information. In the introduction, this article mentions that the average daily caffeine consumption for all adult consumers and from all sources reaches 2.4–4.0 mg/kg for a 60–70 kg subject in the United States, UK and Canada (Nehlig and Boyet, 2000). This excerpt from the

It has been estimated that almost half of 18-24 year olds in Australia have consumed AmEDs and 10% consume them weekly. 90% of adults, 83% of 13-17 year olds and 63% of 6-12 year olds consume caffeine daily. Caffeine is naturally occurring in drinks such as coffee and tea, as well as in foods such as chocolate, but it is also a food additive in carbonated beverages and energy drinks (Catherine W. Striley and Shivani R. Khan Purpose,

Specifically, John Hopkins explains, ¨Around 90 percent of Americans consume caffeine every single day in one form or another. More than half of all American adults consume more than 300 milligrams of caffeine every day, making it America's most popular drug by far.¨ (Bryant, 2015, para 3). Therefore, this quote explains how many people consume caffeine on a daily basis without knowing some basic statistics about caffeine. Coffee is a day to day routine for many people's lives, but an idea that does not cross some people's minds is that coffee has a high quantity of caffeine. The caffeine in the coffee has several side effects like an increases their heart rate, and depending on how sensitive a person is to caffeine, it can cause them to be

Caffeine use has been correlated with people who have a tendency toward addiction such as smoking as well as ingesting more alcohol. The study challenged previous research that believed caffeine users were different than non-users. They used

One on the beneficial effects on caffeine, two the negative effects, and finally on trends in caffeine consumption

Caffeine consumption was associated with fewer cognitive failures. This effect was apparent when non-consumers were compared with consumers which suggest that caffeine withdrawal did not underlie these effects (Smith 2001).

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
