Minum Kopi Hilangkan Depresi

03 Oktober 2011, 09:07 WIB

VIVAnews – Banyak dari kita yang sangat tergantung pada secangkir kopi di pagi hari. Efek kopi umumnya dirasakan sebagai suntikan energi dan semangat untuk menjalani aktivitas sepanjang hari.

Namun, tahukah Anda secangkir kopi di pagi hari tidak hanya memberikan ekstra energi, tetapi juga meningkatkan suasana hati yang berlangsung lebih lama dari yang kita sadari.

Seperti dilansir Daily Mail, sebuah penelitian membuktikan bahwa wanita yang meminum empat cangkir kopi atau lebih setiap harinya akan jauh dari depresi dibandingkan seperlima dari wanita yang tidak meminum kopi.

Dan, mereka yang meminum dua hingga tiga cangkir dapat memotong risiko depresi hingga 15 persen.

Para peneliti dari Universitas Harvard membandingkan asupan kopi dan risiko depresi pada hampi 51 ribu wanita selama 10 tahun. Mereka memang tidak meneliti pria, tetapi penelitian lainnya juga mengatakan bahwa pria memiliki efek yang sama dengan wanita.

Para peneliti menuangkan hasil penelitiannya pada Journal of American Medicine Association. Mereka berpikir bahwa kafein bekerja seperti antidepresan dengan menghentikan produksi beberapa hormon seperti serotonin.

Mereka juga mengatakan bahwa kopi dapat meningkatkan suasana hati dan memberikan energi dalam waktu yang lama. Selain kopi, para peneliti juga menanyakan konsumsi teh, coklat, alkohol setiap harinya, serta apakah mereka melakukan olahraga.

Dari sana, mereka melihat bahwa kopi memiliki dampak yang lebih kuat untuk menghilangkan depresi. Namun, kopi tanpa kafein tidak bekerja sama sekali. “Hasil kami mendukung efek protektif dari kafein, terutama dari kopi, terhadap risiko depresi,” ujar Dr Michel Lucas, dari Fakultas Kesehatan Masyarakat Universitas Harvard.

Meski demikian, menurutnya, investigasi lebih lanjut diperlukan untuk mengonfirmasi hasil temuan ini dan untuk menentukan apakah konsumsi kopi berkafein dapat memberikan kontribusi dalam pencegahan atau pengobatan depresi.

Meningkatkan Sensasi

Para ilmuwan menunjukkan bahwa kafein memiliki efek psikostimulan termasuk meningkatkan sensasi senang dan energi. Mereka berkesimpulan bahwa kopi akan digunakan sebagai antidepresan di masa depan.

Sama halnya seperti pada wanita, penelitian di Finlandia menunjukkan bahwa pria yang mengonsumsi lebih dari empat cangkir kopi setiap hari juga lebih cenderung terhindar dari depresi.

Memang, wanita lebih cenderung depresi dibandingkan wanita. Bahkan satu dari tujuh wanita mengalami depresi di beberapa titik di kehidupannya.vDan bulan lalu, peneliti asal Jerman mengklaim bahwa wanita jaman sekarang dua kali lebih mungkin terserang depresi dibandingkan 40 tahun lalu.

Tak hanya sebagai antidepresan, kopi juga bermanfaat sebagai pencegah kanker prostat, encok, dan Alzhaimer, serta meningkatkan kekuatan otak.

Namun, kopi tak sepenuhnya menguntungkan. Anda tidak dapat mengonsumsinya secara berlebihan karena kopi terbukti secara klinis dapat meningkatkan tekanan darah dan denyut jantung. Bahkan, wanita hamil tidak disarankan minum kopi lebih dari dua cangkir sehari karena dapat berpengaruh pada kehamilan. (ren)

What is Green Coffee?

Green coffee is coffee that remains unroasted. Usually, green coffee beans are picked, processed wet, dried and then milled. However, they are not roasted because that process is usually left to the end consumer. Green coffee can also refer to coffee cultivated and harvested in an environmentally friendly way, but this is a rare use of the term.

Green coffee offers several advantages to the traditional way coffee is delivered to the consumer. Green coffee is one of the freshest ways that coffee can be delivered to the consumer. The coffee beans stay fresher much longer in an unroasted state and, therefore, those coffee connoisseurs who are interested in having the freshest coffee possible will likely be more inclined to choose green coffee.

Once a consumer receives green coffee, they must then choose a way to roast the beans in order to make it suitable for creating the beverage. Green coffee can be roasted in a number of ways, many of which are very simple. Specialty equipment is available for green coffee roasting. However, there are other methods that can be used which do not require special equipment.

Roasting can also take place in a number of ways using equipment not necessarily intended for roasting coffee, but that can be adapted for that purpose. For example, green coffee can be roasted in a stove top popcorn popper, an air popcorn popper or even an oven. In many cases, it may take no longer than 10 minutes to suitably roast the coffee beans, and many say the aroma it provides simply is one of the best smells coffee lovers could ever experience.

Green coffee can be purchased from a variety of locations. Specialty coffee shops may offer the best selection and the employees may be very knowledgeable on roasting green coffee for personal use. Thus, those who are roasting green coffee beans for the first time may feel more comfortable buying their beans from such a location. The Internet is also full of online retailers offering green coffee for sale. Some local supermarkets may also offer a small selection.

It should be noted that because green coffee maintains its freshness much easier in its native form, the best advice may be to not roast any more than may be consumed in a day or two. Therefore, the consumer is always guaranteed of having the freshest coffee possible. Green coffee will stay fresh in its unroasted form for months. However, once it is roasted, the beans have a much shorter time before they become noticeably less fresh. For the experienced coffee drinker, this will lead to a substandard coffee-drinking experience.

Caffeine: How much is too much?

If you rely on caffeine to wake you up and keep you going, you aren’t alone. Caffeine stimulates the central nervous system, alleviating fatigue, increasing wakefulness, and improving concentration and focus.
When to consider cutting back

For most healthy adults, moderate doses of caffeine — 200 to 300 milligrams (mg), or about two to four cups of brewed coffee a day — aren’t harmful. But some circumstances may warrant limiting or even ending your caffeine routine. Read on to see if any of these apply to you.
You drink 4 or more cups a day

Although moderate caffeine intake isn’t likely to cause harm, too much can lead to some unpleasant effects. Heavy daily caffeine use — more than 500 to 600 mg a day — may cause:

Stomach upset
Fast heartbeat
Muscle tremors

Even a little makes you jittery

Some people are more sensitive to caffeine than are others. If you’re susceptible to the effects of caffeine, just small amounts — even one cup of coffee or tea — may prompt unwanted effects, such as restlessness and sleep problems.

How you react to caffeine may be determined in part by how much caffeine you’re used to drinking. People who don’t regularly drink caffeine tend to be more sensitive to its negative effects. Other factors may include body mass, age, medication use and health conditions such as anxiety disorders. Research also suggests that men are more susceptible to the effects of caffeine than are women.

Sooner or later, any self-respecting coffee connoisseur is going to have to pucker up and discover the taste of the infamous Kopi Luwak (civet coffee). It even has Oprah Winfrey’s seal of approval.
And like much that goes all the way to the top – after all, how much higher than The Big O can you go? – debate rages about just how much is quality and how much is hype.
Some coffee experts in Jakarta dismiss the brew as merely another overhyped, commercialized fad. Others, such as culinary legend William Wongso, believe quality Kopi Luwak exists and should be valued.
Even those who aren’t interested in coffee will pause for thought once learning about the extra step in the Kopi Luwak production process – before it passes into your cup, it passes through the bowels of a furry animal.
The Asian palm civet (Paradoxurus hermaphroditus) is a cat-like mammal that lives in coffee plantations in Sulawesi, Java and Sumatra.
The civet is unable to digest coffee beans properly; when it eats them, they pass through its digestive system, ending up back on the ground at the other end, more or less intact.
But not untouched – as the bean makes its journey through the civet’s insides, it is exposed to the animal’s stomach acids and enzymes, which give it a special kind of fermentation. The excreted beans thus take on an unusual taste.
Brewing these beans (after washing, one hopes) produces an unusual drink. The beans are hard to come by, given the specialized harvesting techniques required, which makes it boutique and hard to come by and therefore, to some, very high class.
At the Kopi Luwak café in Mal Kelapa Gading 2, you can try both “pure” Kopi Luwak, or a mere hint in a blend of Luwak (3%) and standard coffee beans.
A 10 gram sachet of the unadulterated variety costs around Rp 75,000 (US$8).
So it’s not just its origin that raises eyebrows. It is reportedly the most expensive coffee in the world.
The high price is a simple matter of supply and demand, says Indonesian coffee expert Alun Evans.
“Is it worth the price? Well I guess that is all in the eye of the beholder.”
Nevertheless, Yudhi, 26, is still eager to try the Indonesian drink.
After all, what does he have to lose – it wouldn’t be the first time someone pays too much for a coffee that tastes like it’s come out of an animal’s rear end.
But 24-year-old Filipe Campos Michel just can’t stop thinking about where it came from.
“I don’t think I could drink it,” he says. “I just don’t think I could.”
Others see it as a special coffee experience, endorsed not only by Oprah but by a civet as well.
“The civet finds a good quality of coffee bean,” Yudhi says. “That’s why people like to drink it.”
The Kopi Luwak is served black, so it is at its richest. It has a deep chocolate color, with a rich, sweet flavor. It is also a little more grainy than standard coffee.
Yudhi, at least, liked it.
“It tastes sort of creamy,” he says. “It has a very strong aftertaste.”
He won’t make it a habit, though, with its designer price tag.
“It is good to try it, but not to drink it all the time.”

Coffee Tied to Lower Stroke Risk in Women

Women who enjoy a daily dose of coffee may like this perk: It might lower their risk of stroke.

Women in a Swedish study who drank at least a cup of coffee everyday had a 0.22 to 0.25 times lower risk of stroke, compared to those who drank less coffee or none at all.

“Coffee drinkers should rejoice,” said Dr. Sharonne Hayes, a cardiologist at Mayo Clinic in Rochester, Minn. “Coffee is often made out to be potentially bad for your heart. There really hasn’t been any study that convincingly said coffee is bad.”

“If you are drinking coffee now, you may be doing some good and you are likely not doing harm,” she added.

But Hayes and other doctors say the study shouldn’t send non-coffee drinkers running to their local coffee shop. The study doesn’t prove that coffee lowers stroke risk, only that coffee drinkers tend to have a lower stroke risk.

“These sorts of epidemiological studies are compelling but they don’t prove cause,” said Dr. David S. Seres, director of medical nutrition at Columbia University’s College of Physicians and Surgeons in New York.

The findings were published online Thursday in the American Heart Association journal Stroke.

Scientists have been studying coffee for years, trying to determine its risks and benefits. The Swedish researchers led by Susanna Larsson at the Karolinska Institute in Stockholm said previous studies on coffee consumption and strokes have had conflicting findings.

“There hasn’t been a consistent message come out,” of coffee studies, said Dr. Cathy Sila, a stroke neurologist at University Hospitals Case Medical Center in Cleveland.

For the observational study, researchers followed 34,670 Swedish women, ages 49 to 83, for about 10 years. The women were asked how much coffee they drank at the start of the study. The researchers checked hospital records to find out how many of the women later had strokes.

There were 1,680 strokes, including those who drank less than a cup or none.

Cup a day enough

Researchers adjusted for differences between the groups that affect stroke risk, such as smoking, weight, high blood pressure and diabetes, and still saw a lower stroke risk among coffee drinkers. Larsson said the benefit was seen whether the women drank a cup or several daily.

“You don’t need to drink so much. One or two cups a day is enough,” she said.

Larsson, who in another study found a link between coffee drinking in Finnish men who smoked and decreased stroke risk, said more research needs to be done to figure out why coffee may be cutting stroke risk. It could be reducing inflammation and improving insulin sensitivity, she said, or it could be the antioxidants in coffee.

Since study participants were asked about their past coffee consumption and then followed over time, there is no way to know if they changed their behaviour.

Women in the study were not asked whether they drank decaf coffee, but most Swedes drink caffeinated coffee, the researchers said.

Larsson and others point out that those who want to reduce their chances of a stroke should focus on the proven ways to lower risk:

  • Don’t smoke.
  • Keep blood pressure in check.
  • Maintain a healthy weight.

Last year, British researchers also reported a link between any coffee drinking and reduced risk of stroke in a general population.
