Recommended: Research on caffeine
Have you ever wonder what does soft drinks, coffee, and medication all have in common? Well I will tell you, they all contain caffeine. Today I will be talking about the health effects of caffeine in your daily diet. I drink coffee daily and I was speculating how that might affect my health. How many of you believe you are caffeine addicts? Or how many cups of coffee do you drink a day? Furthermore, I did some research on the topic and I found that caffeine is prevalent in our society and that there has been many studies that show how caffeine is either good or bad for our well-being, therefore what should we believe?
Granted that I would like to start by sharing the beneficial effects of caffeine and discuss the safe quantities of caffeine

It is mostly known as the life source of most college students, it is a chemical that can drastically improve alertness and concentration. This is a beneficial effect for people who are studying, driving long distances or just people who have monotonous work.
Presently there’s this controversy regarding caffeine and its effects on people’s performance and alertness. Certain people say that energy boosting effects of coffee are in the mind and that only people who don’t drink coffee regularly will get this boost. Although according to British Coffee Association they claim that even regular coffee drinkers will get this boost. Supporting research shows that primary caffeine doesn’t influence someone alertness more than someone who didn’t consume coffee.
Not only but also it is a nervous system stimulant that will affect a myriad of sources of energy inside your body. In fact, studies have shown that increased caffeine consumption can cure the worst of fatigue and keep you motivated and alert throughout your day. Moreover, caffeine also contains antioxidants, which have indicated to have preventive cancer abilities as well as substances that are able to fight a variety of infections building a stronger immune
Caffeine raises your blood pressure when you drink/eat it, raising your blood pressure in general is not a good thing but imagine drinking and/or eating caffeine daily, and your blood pressure constantly rising. Another negative aspect is that caffeine can have a disruptive effect on your sleep. The most obvious effect of the caffeine is that it can make it hard for you to fall asleep. It can help you stay awake during the day but can also make you stay awake during the night when you are trying to fall asleep. You can also have withdraws from caffeine, going back to the story “Java Man” the author Malcolm Gladwell considered it a drug and remember you can get addicted to drugs (you can really get addicted to anything). There are plenty more negative ways caffeine can disrupt your lifestyle but you know what they say for every negative thing you can say there can be some
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.

Vinson, Joe MD. Study: Drinking Coffee has Health Benefits. Retrieved 28 August 2005 from ABC NEWS website: http://abcnews.go.com/GMA/Health/story?id=1074559
Several people rely on caffeine to wake them up or give them a boost of energy when they feel down. Acting as a stimulant, caffeine not only improves concentration and focus, but also stops fatigue (Staff 1). Considered the most commonly used psychoactive drug in the world, approximately 90 percent of adults consume it daily (“MedicineNet.com” 1). But do caffeine buyers really stop to evaluate the possinle harmful effects on their body? Health scares similar to this are not recent. In fact, they have been going on for over 100 years. In 1911, the US Government sued the Coca-Cola company for making their drinks hazardous to other’s health (Lovett 2). Although the Coca-Cola company won, it proves that people worry about what they put into their bodies, even if it does help them stay up to finish their homework. Not everybody will experience the same effects from caffeine. Some people seem more sensitive to caffeine than others (Staff 1). While some will express unwanted effects after only one cup of coffee or tea, others will not notice these same effects until after maybe four or five cups. Although caffeine does include benefits, many downfalls exemplify the stimulant as well. Drinking even small amounts of caffeine daily develops harmful effects on most people’s body and health.
A lot of people often wonder what caffeine is. When isolated in pure form, caffeine is a white crystalline powder that tastes very bitter. The chief source of pure caffeine is the process of decaffeinating coffee or tea. Caffeine is used to provide“boost energy” or a feeling of heightened alertness. 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. If you feel like you have to have caffeine everyday and cannot live without it, then you are considered addicted to caffeine.
...ease of calcium, and reduction of lactic acid is a result of glycogen sparing. In endurance exercise, caffeine allows athletes to exercise for a longer duration through glycogen- sparing, burning fats as fuel, increase calcium production, and increase in alertness and adrenaline. Caffeine is also proven to improve reaction time by the increase amount of adrenaline the caffeine provides. Caffeine also aids in post-work out pain an athlete may experience after a rigorous workout. Caffeine also has its health benefits. Caffeine reduces the risk of: liver cancer by improving enzyme activity, Alzheimer’s by blocking the progression of the disease as a result of the A2A antagonist, and Parkinson’s disease by protecting dopamine- producing cells. Ultimately, caffeine is shown to have a positive effect on an athlete’s performance, and also has positive health benefits.
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
By this definition, and after knowing the effects of caffeine upon the human body, I have come to the conclusion that drinking caffeine is a sign of a lack of respect for oneself, and of an unappreciative attitude toward the life that each of us has been blessed with. Furthermore, it shows of either our inability, or unwillingness to learn to think clearly.
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.
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.
Focus: Many research studies have examined how coffee affects the brain and its functions, and with a healthy diet coffee has many benefits – but also disadvantages.
Caffeine is a chemical found in coffee, tea, soft drinks and various easy to get foods and drinks. Like all drugs, caffeine has its good and bad side. Caffeine’s categorized as a stimulant, meaning it temporarily increases alertness and energy. With this stated, you may ask yourself, what’s so bad about a little high associated with coffee or chocolate? I mean it’s practically harmless, right.
It has been proven to prevent diseases and improve physical and mental ability. Fruits and vegetables also have tons of antioxidants but our bodies seem to absorb the most from coffee. Nutrients from the coffee bean are infused into the drink such as, Riboflavin (Vitamin B2), Pantothenic Acid (Vitamin B5), Manganese and Potassium, Magnesium and Niacin. These beneficial elements can help boost athletic performance, if taken at the right time before a workout. Caffeine increases the number of fatty acids in the bloodstream, which allows athletes' muscles to absorb and burn those fats for fuel, therefore saving the body's small reserves of carbohydrates for later on in the exercise.
