“Pros and Cons about Consuming Coffee”

Caffeine addict, It feeling of “hanging out” with a cup of coffee can be described and understood only by those who consume this hot and precious beverage. The habit of drinking coffee cannot be compared to anything else. This habit is especially experienced every time, over and over, each time drinking coffee. Besides that coffee gives a sense of satisfaction, its consumption has certain advantages very positive effect on health compared to other ingredients in our daily intake. Coffee also has negative consequences in terms of health are closely screaming with the inserted daily amount of coffee in the body. But then, there are a number of undeniable advantages to come across us should we decide to throw the coffee out of our life.

First, it'd be better for diet. Some medicines and dietary supplements for weight loss. Caffeine is a primary ingredient in many over the counter diet pills, but whether this actually has any effect on weight loss (the theory is that metabolism in increased) remains undemonstrated in any rigorous fashion. “Coffee consumption fits into a very healthy diet and, if anything, may have a beneficial effect,” Dr. Eileen Madden, a toxicologist and food-safety expert, told a symposium on coffee and health last fall at the New York Academy of Sciences. There’s a good reason for that caffeine is one of the very few natural substances that have actually been proven to aid fat burning. Several studies show that caffeine can boost the metabolic rate by 3-11% (10, 11). Other studies show that caffeine can specifically increase the burning of fat, by as much as 10% in obese individuals and 29% in lean people

Second, the other benefit of consuming coffee is coffee can improve energy levels and make you smarter. Coffee can help people feel less tired and increase energy levels. This is because it contains a stimulant called caffeine, which is actually the most commonly consumed psychoactive substance in the world. After you drink coffee, the caffeine is absorbed into the bloodstream. From there, it travels into the brain. In the brain, caffeine blocks an inhibitory neurotransmitter called Adenosine. When that happens, the amount of other neurotransmitters like nor epinephrine and dopamine actually increases, leading to enhanced firing of neurons. Many controlled trials in humans show that coffee improves various aspects of brain function. This includes memory, mood, vigilance, energy levels, reaction times and general cognitive function.

On the other hand, Caffeine Is Highly Addictive. About 68% of Americans in 2006 said they were hooked on coffee, according to the National Coffee Association. This one has some truth to it, depending on what you mean by "addictive." Caffeine is a stimulant to the central nervous system, and regular use of caffeine does cause mild physical dependence "Caffeine exaggerates the stress response," says James D. Lane, PhD, professor of medical psychology at Duke University Medical Center in Durham, N.C., and a long-time caffeine researcher. "At the cellular level, caffeine locks the receptor normally used by adenosine, a brain modulator that provides feedback to avoid overstimulation of nerve cells. If adenosine is locked up, nothing keeps the nervous system from getting too excited at a cellular level." And Roland R. Griffiths, PhD, professor in the departments of psychiatry and neuroscience at Johns Hopkins University School of Medicine in Baltimore and a veteran researcher in the area. Caffeine is addictive for some people, he says. “There’s no question that caffeine does produce dependence, and caffeine withdrawal is a real syndrome."

According to the other sources, coffee consumption has also negative health effects. Caffeine is such a powerful stimulant, people are known to have overdosed on espressos, and drinking too much has been associated with negative health effects, such as insomnia, jitteriness, dieresis and headaches. The Mayo Clinic state that consuming more than 500-600 mg of caffeine a day may lead to insomnia, nervousness, restlessness, irritability, an upset stomach, a fast heartbeat and even muscle tremors. However, previous research has linked even moderate amounts of caffeine to   health effects. Last year, Medical News Today reported on a study suggesting that consuming 300 mg of caffeine a day during pregnancy may increase the risk of low birth weight babies, while other research suggests that drinking four cups of coffee a day may increase the risk of early death.

            For example, A wrongful-death lawsuit filed last week against the makers of Monster energy drinks claims that 14-year-old Anais Fournier drank two 24-ounce cans of Monster in the day before she unexpectedly died late in 2011. The coroner's report described "caffeine toxicity" as contributing to her death. Just what does it take to ingest a lethal dose of caffeine? The answer is hard to pin down, in part because it happens so rarely, but it's clearly a hell of a lot. In an email, Jack James, the editor-in-chief of the Journal of Caffeine Research, says that overdose for adults requires roughly 10 grams of caffeine. (People typically ingest just 1 to 2 mg/kg of caffeine per beverage.) A 2005 Forensic Science International article on two fatal caffeine overdoses in New Mexico pegs the figure closer to about 5 grams--an amount that would still require drinking more than 6 gallons of McDonald's coffee. Whereas a normal cup of coffee might bring the concentration of caffeine in your plasma to 2.5 to 7 mg/L, the two people who died in New Mexico--a woman who might've used caffeine to cut intravenous drugs, and a man whose family said he ingested a bottle of sleeping pills--both had concentrations 100 times higher. (A web application called "Death By Caffeine" uses a benchmark around 6 grams per hundred pounds of body weight to estimate death, but it's "for entertainment purposes only.")

So if a true caffeine overdose is so rare, why has caffeine--perhaps the most widely used drug in North America--been blamed for contributing to a handful of deaths over the years? Perhaps because it almost always works in concert with other far more nefarious factors such as alcohol or heart conditions. Indeed, the suit filed in California points out that Fournier suffered from Ehlers-Danlos syndrome. According to the autopsy report, the cause of death was a cardiac arrhythmia that the caffeine brought on. But the arrhythmia was also complicated by "mitral valve regurgitation in the setting of Ehrlers-Danlos syndrome," which affects collagen synthesis and thus multiple body systems, including the cardiovascular system.

"Caffeine toxicity of the kind experienced by Ms. Fournier (if, indeed, that is what she experienced) is not well understood," James says. "There is speculation in the literature regarding the possibility of some individuals having a peculiar sensitivity to caffeine, but there is no clear definition or understanding of what such sensitivity might be.

"One thing is clear: Anais's caffeine intake simply would not be harmful for most people. Two cans of Monster each contain 240 mg of caffeine, which the lawsuit equated with the caffeine of 14 12-oz. cans of Coca-Cola. While drinking 14 Cokes sounds positively disgusting, the caffeine therein is actually well within the bounds of what many people consume in a day. For instance, Starbucks Pike Place coffee would deliver that 480 mg of caffeine with just 24 ounces of Joe. As Mark F. McCarty, an applied nutritionist in San Diego, said: "I don't see another case of a child who died from acute exposure to the equivalent of four coffee cups of caffeine. That strikes me as extremely rare. I can't imagine that Monster was worried about this, because there's nothing in the literature to suggest this would happen."

            It is concluded that the facts are clear. The good things happen for a reason and some times, with a risk. When we love someone, we take it/him/her the way it/him/her is. We love coffee. It would perhaps shorten the healthy side of our life span but I guess that would be the risk we have to endure.
