Coffee has always been a controversial subject as far as health goes. Many people look at coffee and think “caffeine.” They define the long and short term effects of coffee on what they know about caffeine, not knowing that there are many other components to coffee that can both positively and negatively impact their health. Coffee can diversely affect many different aspects of people’s general health. It can impact anything from the digestive system and the reception of neurochemicals, to sleep patterns and post-workout soreness.
One of the most well-known effects that coffee produces is increased alertness. This effect is different between regular and irregular coffee drinkers. For irregulars, the caffeine will actually give them a boost in energy. Once people get into a pattern of drinking coffee regularly, they feel more alert for different reasons. Caffeine blocks adenosine, a chemical that induces drowsiness, increasing concentration and reaction speed. The long term effect is that brain starts depending on caffeine as a stimulant, and without it, a neural lethargy arises.

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.

In this year there were products that the average person used that had amounts of cocaine in it. The products that had cocaine in it were the beverage coke cola and medicine for numbing your gums. But before manufactures’ were using cocaine in things we use, three thousand years before the ancient Inca people use to chew coca leaves, which is one of the ingredients of making cocaine. They chewed coco leaves to get there heart racing and to speed up their breathing so they can work longer hours and because they lived where there was thin air.

Fifty-four percent of Americans over the age of eighteen drink coffee daily, and it seems that over the past 100 years, humans have gradually increased in height. Supposedly, there’s an old wives’ tale that claims “coffee stunts your growth.” The exact origin of the myth rests unknown, but it thought to have originated from the Europeans (Grabinski et al. 2). Over several decades, multiple studies have concluded that coffee actually does not stunt growth, helping to diminish previous ideas that it did.

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.
As side from that, excess caffeine can also overstimulate the central nervous system, disrupting sleeping patterns. High amounts of caffeine produce negative effect on sleep onset and quality. However, there are large individual differences in the effects of caffeine on sleep. Many people consume coffee during the evening and have no problems falling asleep, while others find that the mild stimulation of caffeine consumed shortly before a bed time delays the time to fall asleep.
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.
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 it 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. Innovative foods are coming out infused with coffee, and energy drinks are being pushed at every angle. Caffeine to many is a necessity to wake up in the morning and for others to stay up all night. This is dangerous because people are not only becoming more and more dependent on coffee drinks and energy drinks but they are beginning to ingest more of it each day and are now mixing it with other drugs that can be life threatening. Proper knowledge is important when taking any drug including one that the FDA considers to be a safe multi-purpose food substance and education is the key.
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.
When a person drinks coffee, the caffeine is absorbed into the bloodstream and then travels to the brain where it blocks an inhibitory neurotransmitter called Adenosine. When this happens, the amount of other neurotransmitters actually increases.
