I. Introduction A. I would venture to say that most of us in this room like to start our day with a cup of coffee. It’s delicious, energizing, and relatively convenient with the campus Starbucks at our disposal. In our culture, this is nothing uncommon. The United States Food and Drug Administration reports that around 80 percent of adults in America consume some form of caffeine every day. For those that do, however, many fail to consider

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.
This informative speech is talking about the effect of caffeine on human body. At the beginning, the speech explains that caffeine can be absorbed by human body in only 30 to 35 minutes after consuming. Then, the speech explains that caffeine can be found not only in coffee but also in energy drink, chocolate, candy bar, and some certain medicine. On the next part, the speech describe that caffeine can affect the three major systems in human body. The first one is the nervous systems. Consuming caffeine can increase the rate to send impulses in the nervous system. In the other word, the process of sending messages can be done quicker. This is one of the good effects of caffeine in our body. The second one is the cardiovascular systems. Caffeine gives a bad effect in our cardiovascular systems by raising the blood pressure and takes a part in building up fatty acid in the heart. That fatty acid can cause blood clot that occurs when blood hardens from liquid to solid. The third one is the urinary systems. Caffeine can disrupt or increase our urinary frequency. In this case, caffeine on...

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 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 raises adrenaline levels and heavy coffee consumption can lead to a state of adrenal gland exhaustion where the adrenal glands are no longer able to adequately respond to stress by releasing enough adrenaline. Adrenal insufficiency can then lead to a host of other problems, including a weakened immune system response, anxiety and panic attacks.
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
General Purpose:To inform about eating disorders Specific Purpose: To inform my audience about eating disorders and the different types. Central Idea: Eating disorders are very common and they cause many people to go through hard things. They can affect anyone and once you develop an eating disorder you will have it for the rest of your life it doesn't just go away.
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.
Caffeine is one of the most popularly used psychoactive substance across the globe, easily found in various products in significant amounts, like coffee, tea, cola drinks and so on. The role of caffeine and its effects on one’s health can be described simply by the word, ‘psychoactive’. This drug, mostly consumed for its positive effects like increasing alertness and boosting one’s energy has gained much popularity amongst various generations, from adults to children. The most commonly used form of caffeine amongst adults is coffee, while the most popular source amongst children are soft drinks like coco - cola, pepsi, red bull etc. 70% of all soft drinks contain caffeine.
Lastly, a common side effect of coffee we all may have experienced is the staining of teeth and dehydration. After a while, without proper care coffee can permanently stain and damage your dental. Also the caffeine in coffee is a mild diuretic and can increase the volume of urine excreted. However, this effect can be easily counteracted by the drinking of an extra glass of
“Fasting is an effective and safe method of helping the body detoxify itself.” Quote by: James F. Balch, and Phyllis A. Balch. When you begin fasting, toxins are created in your body, mostly because of food and water. During your fast your body is provided resting time, most importantly, it gives your organs a rest which could potentially prolong your life. To prepare yourself for a fast you should try to eat mostly fruits, and vegetables. Intermittent fasting means fasting for certain hours of a day. While periodic fasting is when you fast for three days or longer for two or more weeks. The description of hunger is when your bodies respond to lack of food, then your body begins searching for food. If you get hungry during your fast it’s advised that you eat watermelon (if you absolutely need it), drink lemon juice or coffee. While giving organs rest and creating longevity, fasting is a controlled medical regimen.
Caffeine is considered to be a psychostimulant along with other stimulants such as amphetamines, methamphetamines, ephedrine, nicotine, cocaine, and alcohol. Understanding the effects of caffeine can be difficult because it is most commonly associated with keeping humans aroused and awake. However, there are other effects of being exposed to caffeine that are not considered a benefit from the intake. I chose caffeine as the topic of discussion because I am not well educated on caffeine consumption and the effects of it. I find it interesting to learn more about it being that it is in the same category as illicit drugs.
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 is 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.
