The Low Down On Caffiene THE LOW DOWN ON CAFFEINE A Statement of the Problem Caffeine is on trial, I am the judge. My verdict? I do not know but I will. I am determined to find truth, and accomplishing that task will be difficult, but very fulfilling. To determine whether caffeine is guilty of its charges, I will develop an intense experiment packed full of the scientific method.
Accompanied by this experiment will be extreme background knowledge to guide me to my verdict. Strap in and enjoy the ride; here is caffeines story: I grew up in an environment that was very hostile toward the compound caffeine. It was tough.I recall being in numerous situations where my buds would be sipping on a cold Mountain Dew, or another soft drink which obtained caffeine, and I would be sipping a warm glass of V8 Juice. That stuff is terrible, it really is. I felt isolated, for I was limited to only so many beverages, none of them that were cool either. After awhile, my ashamed secret was let out to my entire school, and for 4 years my peers ostracized me for being the square baby bottle boy who could not drink the cool caffeine soda. My social life ceased to be; this forced me to deeply concentrate on the subject of caffeine and caffeine products.
I still do think about caffeine. I now question my fathers fervent belief that caffeine was a drug that chained its users into a lifetime of addiction; a tool used by greedy corporations to capture more consumers. I also question the horrible effects my dad claims caffeine has on the nervous and digestive system. I keep thinking, could this compound really be that bad? By using the opportunity given to me by this project, I will fulfill my curiosity about caffeine and design a scientific experiment. With this experiment, I will answer the questions: 1) Does increased amounts of caffeine form dependency? 2) How does caffeine affect the speed of our bodies? 3) How does caffeine affect our systems digestive process? Many factors may influence this topic.My biased view which has generated from years of brainwashing by my father influence my interpretations of research and influence my hypothesis.
Physiological biases may influence the way in which I shape my experiments. However I have researched and designed an experiment which reflect little to no bias by me, I have kept open minded in my quest for truth. I am happy I chose this problem; I have learned not to blindly except the theories and ideas of my father but thoroughly investigate them myself and establish a closer truth through research and through the scientific method. Review of Literature -Caffeine in its molecular form The compound Caffeine (C8H10N4O2) is recognized by a plethora of other names, from 1,3,7-Trimethylxanthine and 1,2,3,6-tetrahydropurine to just plain No-Doz (Britannica 1999).Caffeine is a white powder substance or silky needle substance. The compound is very soluble in hot water, and when it cools, the solution deposits crystals of caffeine monohydrate (Britannica 1999).
Caffeine is used as an additive in certain food products; it is a central nervous system stimulant and a diuretic (Powers SK). Caffeine is an alkaloid. There are numerous compounds called alkaloids, among them we have the methylxanthines, with three distinguished compounds: caffeine, theophylline, and theobromine, found in cola nuts, coffee, tea, cacao beans, mate and other plants.These compounds have different biochemical effects, and are present in different ratios in the different plant sources. These compounds are very similar and differ only by the presence of methyl groups in two positions of the chemical structure. They are easily oxidized to uric acid and other methyluric acids that are also similar in chemical structure (Caffeine Blues). Caffeine is consumed very often. An average cup of coffee contains about 100 mg (.
003 ounce) of caffeine.Tea also incorporates caffeine into its solution. In a 12-ounce glass of carbonated cola beverage, there is about 40 mg of caffeine (Britannica 1999). Caffeine is present in many of our beverages and foods.
People probably drink a lot more than they realize. According to the National Soft Drink Association, the following is the caffeine content in mgs per 12 oz can of soda (Caffeine Consumed Miller): 1. Afri-Cola 100.0 (?) 2.Jolt 71.

After absorption, it passes into the central nervous system. Caffeine sensitivity refers to the amount of caffeine that will produce negative side effects.This amount will vary from person to person. Caffeine does not accumulate in the bloodstream nor is it stored in the body. It is excreted in the urine many hours after it has been consumed (Caffeine Blues Cherniske). Caffeine may be used as a treatment for migraine headaches and in relieving, for a short time, fatigue or drowsiness. Caffeine may be used for medicinal reasons.Caffeine is a pharmaceutical drug.
It helps blood flow to the brain in a more fluid fashion and helps prevent migraines (article 1). It improves motor performance, decreases fatigue, enhances sensory activity, and increases alertness (Britannica 1999). It also has been thought to improve endurance exercise (Endur.
Powers). Caffeine will not reduce the effects of alcohol, although many people still believe a cup of coffee will sober up an intoxicated person (Chronic Temples). Caffeine has become very popular because of these reasons.However, there is a down side to this drug.
Caffeine intake may also produce irritability, nervousness or anxiety, jitteriness, headaches, and insomnia (Britannica 1999). Excessive caffeine intake can lead to a fast heart rate, dieresis (excessive excretion of fluids), nausea and vomiting, restlessness, anxiety, depression, tremors, and difficulty sleeping (Kids Walmer). The effect of caffeine on health has been widely studied. In particular, the effects of caffeine on fibrocystic breast disease, cardiovascular disease, birth defects, reproductive function, and behavior in children have been closely examined.
A 1984 statement from the American Medical Association Council on Scientific Affairs stated, Moderate tea or coffee drinkers probably have no concern for their health relative to their caffeine consumption provided other lifestyle habits (diet, alcohol consumption) are moderate as well.(Chronic Temples).This statement puts caffeine use in perspective. Caffeine increases the level of circulating fatty acids.
This has been shown to increase the oxidation of these fuels, hence enhancing fat oxidation. Caffeine has been used for years by runners and endurance people to enhance fatty acid metabolism (Endur Powers). It’s particularly effective in those who are not habitual users. It does affect metabolism, though it is a good question whether its use truly makes any difference during a diet.The questionable rationale for its original inclusion in diet pills was to make a poor man’s amphetamine-like preparation from the non-stimulant sympathomimetic phenylpropanolamine and the stimulant caffeine.
(That you end up with something very non-amphetamine like is neither here nor there.) The combination drugs were called Dexatrim or Dexa-whosis (as in Dexedrine) for a reason, namely, to assert its similarity in the minds of prospective buyers. However, caffeine has not been in OTC diet pills for many years per order of the FDA, which stated that there was no evidence of efficacy for such a combination (Endur Powers).Caffeine has been proven an effective stimulant that speeds the body up (Endur Powers).
Because of all these qualities, caffeine has become very popular. Nevertheless, there a downside to using it every day, do people fool themselves into thinking that theyre not addicted to the stuff when they really are? Caffeine is the most widely consumed behaviorally active substance in the world. Chronic caffeine intake only appears to have minor negative affects on health and that is why government regulatory agencies do not impose restrictions on it (Chronic Temples). However, some years ago it was pointed …
