Introduction Attention Catcher: How many of you had a cup of coffee today? How about in the past week? Coffee in America is an everyday drink for most people. It is the second most consumed beverage behind water. Thesis: I believe that we need to drink coffee and that there are many positives for consuming coffee. Preview:

Positive Information on Coffee
Coffee may counter several risk factors for heart attack and stroke.
First, there's the potential effect on type 2 diabetes risk. Type 2 diabetes makes heart disease and stroke more likely.
Besides that, coffee has been linked to lower risks for heart rhythm disturbances (another heart attack and stroke risk factor) in men and women, and lower risk for strokes in women.
In a study of about 130,000 Kaiser Permanente health plan members, people who reported drinking 1-3 cups of coffee per day were 20% less likely to be hospitalized for abnormal heart rhythms (arrhythmias) than nondrinkers, regardless of other risk factors.
And, for women, coffee may mean a lower risk of stroke.
In 2009, a study of 83,700 nurses enrolled in the long-term Nurses' Health Study showed a 20% lower risk of stroke in those who reported drinking two or more cups of coffee daily compared to women who drank less coffee or none at all. That pattern held regardless of whether the women had high blood pressure, high cholesterol levels, and type 2 diabetes.
“For Parkinson’s disease, the data have always been very consistent: higher consumption of coffee is associated with decreased risk of Parkinson’s,” Hu tells WebMD. That seems to be due to caffeine, though exactly how that works isn't clear, Hu notes.
Coffee has also been linked to lower risk of dementia, including Alzheimer’s disease. A 2009 study from Finland and Sweden showed that, out of 1,400 people followed for about 20 years, those who reported drinking 3-5 cups of coffee daily were 65% less likely to develop dementia and Alzheimer’s disease, compared with nondrinkers or occasional coffee drinkers.

Coffee can make you smarter. Active ingredient is caffeine, which is a stimulant, and the most commonly consumed psychoactive substance in the world. It blocks the effects of adenosine. It actually increases the neuronal firing in the brain and release of other neurotransmitters like dopamine and norepinephrine. Caffeine can improve mood, reaction time, memory vigilance and general cognitive function.
Coffee can help you burn fat and improves physical performance. It raises metabolism and increases the oxidation of fatty acids. Caffeine was found to increase exercise performance by 12 percent on average.
Coffee may drastically lower your rise of type 2 diabetes. The reduction risk ranges from as low as 23 percent to a high of 67 percent. A massive study of almost 500,000 people and found that the more coffee people drank decreases their risk.
Coffee may lower your rise of Alzheimer and Parkinson’s. Coffee may protect your brain in old age. Alzheimer’s disease is the most common neurodegenerative disorder in the world and a leading cause of dementia. In studies coffee drinkers have up to a 60 percent lower risk of Alzheimer’s and dementia. Parkinson’s is the second most common neurodegenerative disorder, characterized by death of dopamine generating neurons in the brain. Coffee may lower the rise of Parkinson’s by 32-60 percent. The bottom line is that coffee is associated with a much lower risk of dementia and the neurodegenerative disorders of Alzheimer and Parkinson’s.
Coffee may be extremely good for your liver. The liver is very vulnerable to excess consumptions of alcohol and fructose. Multiple studies have shown that coffee can lower the risk of cirrhosis by as much as 80 percent, with the strongest effect for those who drank four or more cups per day. Coffee may also lower the risk of liver cancer by around 40 percent.
Coffee is loaded with nutrients and antioxidants. It is also the biggest source of antioxidants in the modern diet.

coffee seeds are a major cash crop, and an important export product, counting for over 50% of some developing nations' foreign exchange earnings.[3] The United States imports more coffee than any other nation.[4] The per capita consumption of coffee in the United States in 2011 was 4.24 kg (9 lbs), and the value of coffee imported exceeded $8 billion.[5] Coffee is also a great reason to gather with friends, go out on a first time date. coffee is grown in the coffee belt. Based on climate it cant be grown in the usa. So all the coffee that we drink is from world wide locations.
Fare trade and ethical sourcing. Really important. By 2015 starbucks plans on making all of its coffee fare trade.
A study done with coffee drinkers at work, more satisfied with job and life in general. It is more of a psychological aspect of coffee.
America’s fuel is coffee.
Headaches. The strong migraine medicine is Tylenol with caffeine.

One reason why this drink is good for you is that it can ward off depression. A Harvard school of public health did this study to prove that it was factual. It actually concluded coffee consumption decreased depression by 20 percent. They also realized that the more coffee you drank could lower the risk of depression even more.
A large study with 50,000 men by the same Harvard public health realized that men who drank 6 or more cups of coffee a day could reduce their risk of colon cancer by 20 percent. If you don't like caffeine in your coffee then that's ok too, because the study proved that caffeine was not the determining factor for the decrease in colon cancer.

Coffee is no longer thought to be a risk factor for coronary heart disease.[128] A 2012 meta-analysis concluded that people who drank moderate amounts of coffee had a lower rate of heart failure, with the biggest effect found for those who drank more than four cups a day.[129] Moreover, habitual coffee consumption is associated with improved vascular function.[130][131] Caffeine acts as an acute antidepressant.[132] A review published in 2004 indicated a negative correlation between suicide rates and coffee consumption.[133] It was suggested that the action of caffeine in blocking the inhibitory effects of adenosine on dopamine nerves in the brain reduced feelings of depression.[133] Coffee consumption is also associated with improved endothelial function.[134] Coffee extracts have been shown to inhibit 11beta-hydroxysteroid dehydrogenase type 1, enzyme which converts cortisone to cortisol and is a current pharmaceutical target for the treatment of diabetes type 2 and the metabolic syndrome

Only about 1 percent of coffee exported is considered fair trade. A 2005 study done in Belgium concluded that consumers' buying behavior is not consistent with their positive attitude toward ethical products. On average 46% of European consumers claimed to be willing to pay substantially more for ethical products, including fair-trade products such as coffee.…...

...A Happier and Longer Life with Coffee Coffee is one of the most popular drinks in the world for its great aroma, smooth taste, and energizing effect. Coffee is drink in virtually all countries in the world. Coffee is actually a drink that brings all kinds of health benefits. This article lists all of the health benefits you can get from enjoying a cup of coffee daily. Coffee is known for its health benefits as it contains antioxidants. These antioxidants are known to provide anti-aging properties and protection against degenerative diseases such as cancers. In fact, research has found that some people get their main antioxidant fix from coffee. For Americans, coffee is the number one source of antioxidants. Although there are other sources of antioxidants, such as fresh fruits and veggies, the human body is able to absorb more of these beneficial substances from coffee. Coffee contains caffeine which is a natural stimulant. It helps sports men and women recover from extreme exercise. "If you give an athlete more petrol in the tank, they will go further. What we've done is to give them 50-60 per cent more petrol," said Professor John Hawley, head of the exercise metabolism group at the Royal Melbourne Institute of Technology in Victoria, Australia. In the study, athletes cycled to exhaustion before eating a carbohydrate sports drink, bar or gel with a high caffeine dose immediately after the exercise, and then two hours later.

...Coffee is consumed by many individuals to aid with energy and alertness. Coffee is hot, aromatic, and considered enjoyable by many. The first documented use of coffee was in the 15th century in the Sufi monasteries in the part of the world that is now Yemen. The Sufis used the beverage to aid in concentration and to keep themselves alert while performing night time devotions. While most will have no problem drinking one or two cups of coffee a day, drinking too much coffee can cause health problems and lead to coffee dependence. Caffeine in coffee is the drug that causes many of the effects of coffee. Caffeine is a stimulant which many people use to wake up in the morning and stay mentally alert throughout the day. Studies show that 30 milligrams or less of caffeine can alter mood and affect behavior and 100 mg per day can lead to physical dependence and withdrawal symptoms upon abstinence. The most common withdrawal symptoms: headache, fatigue, drowsiness, difficulty concentrating, decreased motivation, irritability, depression, anxiety, flu-like symptoms, and impaired cognitive performance. Students in college, for example, can easily become dependent on coffee. Classroom hours are demanding and students must be alert. College also requires many hours of concentration and focus to complete assignments, and prepare for test. Students must also find time for activities of daily living, and......

...Healthy Coffee Alternatives In the Hungry For Change Book we discuss the addictive nature of caffeine and when consumed in large quantities, can lead to adrenal fatigue. Coffee is also a diuretic, meaning it purges water from your body. That said, if you want to function at a high level and remain well hydrated, then it would be a better choice to replace coffee with a natural alternative. The list below provides some great tasting substitutes. Teeccino Caffeine-free Herbal Coffee This coffee alternative is popular among those who have removed regular coffee from their diets because it tastes very similar to coffee but is caffeine free. A mix of carob, barley, chicory nuts and other flavors (there are all kinds of varieties) it is truly tasty, can be brewed like coffee (in a French press, via tea bags or in an espresso machine), and mixes nicely with milk, soy milk or just plain honey if you’re more of a black coffee/milk-free person. Yerbe Mate If you're not necessarily seeking a coffee taste, this herbal tea with numerous health benefits is a great choice. Not only does Yerbe Mate taste great hot or cold but it has powerful antioxidant properties, and it can also accelerate weight loss as it revs up the metabolism. Green Tea Green tea has less caffeine than a cup of coffee but enough to give you a boost without any of the coffee jitters.

...Compare and contrast essay Coffee Everyone has heard or seen, at least a couple, quips about mornings and coffee. “Coffee-the jet fuel for the morning impaired.” “Sure I’m addicted. But, the life my morning coffee saves today, might just be yours.” There are several options when it comes to getting a morning caffeine jolt, espresso, latte, cappuccino, and plain brewed coffee. Two popular choices are the latte and brewed coffee. A latte is an espresso drink with steamed milk, while a brewed coffee is hot water that has been ran through coffee grounds and a filter. The cups look the same; the substance looks similar; and they both give you a caffeine jolt. Even though they may look similar, and they have some of the same ingredients, there are a few important facts to consider when choosing a morning pick me up. Four major differences are the taste, caffeine content, cost, and nutritional value. First, taste is a major deciding factor. A latte is made with equal parts espresso and milk, so it has a sweet flavor, and because it is made with milk it has a creamy texture that makes people feel all fuzzy inside, like a favorite pair of slippers. Also, flavors like mocha, vanilla, caramel, and mint, can be added to Lattes to give it a unique taste. Meanwhile, brewed coffee has more the consistency of water and is bitter, but, at the same time, it still has the unique flavor that many have come to associate with their morning rituals. To counter the bitterness, flavors,......
