Coffee is very popular as a morning drink. Many people throughout the world choose to drink a cup of coffee to start the day in order to make the body and mind fresher. Coffee is also commonly known as a companion beverage for those who want to stay up all night long. Many researches found that drank three cups of coffee or more in a day gave healthy benefits. A thirteen-year-research involving more than four hundred thousand people conducted by the National Cancer Institute and published in the “New England Journal of Medicine”, concluded that the coffee drinkers had a sixteen percent decrease in the risk of premature death. Drinking coffee may increase the stress hormone level in the body and lead to addiction to caffeine. However, the following are some of the healthy benefits of coffee, with an emphasized note that you should limit the usage of cream and sugar. Preventing Gallstone Disease In 2002, Harvard researchers found that women who drank at least four cups of coffee a day had twenty-five percent lower risk of gallstones than those who didn’t. A previous study found a similar result for men. Preventing Depression According to a 2011 report in the “Archives of Internal Medicine”, said that women who drank two to three cups of coffee a day were fifteen percent less likely to experience depression, and those who drank four cups of coffee had a twenty percent lower risk. Improving Memory Coffee may help to improve memory, both long and short-term memory. In a 2005 study presented at the Radiological Society of North America, the researchers concluded that people who drank at least two cups of caffeinated coffee would improve short-term memory and fast reaction. A study in 2007 found that sixty-five-year-old women and above who regularly drank three cups of coffee or more a day had better performance on memory tests and were less likely to show memory loss than those who drank only one cup a day. Reducing the Risk of Diabetes Many studies showed that coffee drinkers were less likely to develop diabetes type two. A report in January 2012 in the “Journal of Agricultural and Food Chemistry” explained furthermore about the reason. That was because the compounds contained in coffee would deter hIAPP (a polypeptide that produces abnormal protein fibers), which were found in people with diabetes type two. Reducing the Risk of Cancer Coffee consumption has been associated with a reduced risk of breast cancer, endometrial, prostate and liver cancer. A 2008 study in Sweden found that women who drank at least two to three cups of coffee a day might reduce the risk of breast cancer or delaying the onset of breast cancer. The other study recently published by the Harvard School of Public Health found that coffee might decrease the risk of prostate cancer. Increasing Metabolism Coffee can help you maintain or even lose weight. An old study in 1980 found that the caffeine in coffee stimulated the body’s metabolism, and it happened only in the “normal” people while the people who were obese experienced greater fat oxidation. Reducing the Risk of Parkinson’s Disease “Journal of the American Medical Association” in 2000 found that the consumption of caffeine and coffee would produce a lower risk of developing Parkinson’s. A 2010 study also found that people who drank two to three cups of coffee every day were twenty-five percent less likely to have the disease. Containing High Antioxidants A Harvard researcher, Edward Giovannucci, in “Cancer Epidemiology, Biomarkers & Prevention” wrote that coffee has more antioxidants than most vegetables and fruits. In fact, a 2005 study found that coffee was in the highest rank as a source of antioxidants in the American diet. Improving Stamina Coffee and its caffeine may improve endurance and short-term performance. A 2008 study concluded that the benefit of caffeine that was taken one hour before exercise at a dose of four milligrams per kg body weight showed remarkable endurance. Preventing Rheumatism A 2007 study involving forty-year-old men or above concluded that a long-term coffee consumption reduced the risk of having rheumatism. Both regular coffee and decaf gave a positive impact. Those who drank six cups of coffee a day had a sixty percent lower risk to avoid rheumatism.

Nema dvojbe - kava je sigurno jedan od najpopularnijih napitaka, a potvrđuje to i podatak da se proizvodnja tog crnog zrna u četrdesetak godina udvostručila. U Hrvatskoj kavu svakodnevno pije 80 posto starijih od 15 godina, a na zagrebačkoj špici svake se subote popije barem desetak tisuća šalica kratke, duge, macchiata ili obične s mlijekom... No, kad se govori o kavi i zdravlju, obično se ističu negativne strane ovog popularnog napitka. Ipak, u posljednjih nekoliko godina pojavile su se i ozbiljne studije koje sve češće pozitivno govore o kavi. Nema veće smrtnosti Prije četiri godine bilježi se prva studija koja je skinula krimen s kave. Znanstvenici s Harvarda na čak 130.000 ljubitelja crnog napitka dokazali su da nema povezanosti redovitog konzumiranja šest šalica kave s povećanjem smrtnosti kod muškaraca i žena pa čak niti za rizik od kardiovaskularnih bolesti i raka kako se dugo vjerovalo. Nemojte pušiti Neke kasnije studije i u Europi i SAD-u potvrdile su ovo otkriće koje je napokon umirilo kavopije. Naime, stručnjaci s Mayo klinike tvrde da prijašnja istraživanja po kojima je kava opasnost za zdravlje nisu uzela u obzir da oni koji ne mogu bez kave nerijetko pretjerano puše i nisu ljubitelji tjelesnih aktivnosti, a sve su to rizici za zdravlje očito veći od onih koji bi mogla izazvati kava. Dapače, veći dio studija posljednjih nekoliko godina dokazao je da kava može imati vrlo povoljan učinak na zdravlje. Kako kava utječe na bolesti poput raka, dijabetesa, Alzheimerove ili Parkinsonove bolesti, pokazale su novije studije. Bolesti srca i moždani udar Studija Američkog kardiološkog društva, objavljena prije dvije godine, pokazala je da su oni koji su pili jednu do tri šalice kave dnevno rjeđe hospitalizirani zbog poremećaja srčanog ritma negoli oni kojima kava nije previše dragi napitak. I jedna ovogodišnja studija pokazala je da umjerene količine kave mogu štititi srce. Desetogodišnje istraživanje pokazalo je da su žene koje su pile više od jedne šalice kave na dan imale manji rizik za moždani udar i to za 22 do 24 posto, a rezultati su bili isti čak i ako su ispitanice bile pušačice, ili pile alkohol, imale visoki tlak ili dijabetes. Rak Agresivni rak prostate, endometrija, estrogenski neovisan rak dojke, rak jetre ... samo su neke od zloćudnih bolesti za koje bi kava mogla smanjiti rizik. Znanstvenici s Harvarda smatraju da su razlog antioksidativne i protuupalne tvari kojih u kavi ima više nego u većini voća i povrća. Boljitak od kave je jednak bez obzira na to sadrži ili kofein ili ne. U tijeku su ispitivanja koja bi pokazala ima li kava utjecaja na smanjenje rizika od raka jetre jer su dva istraživanja u Finskoj i Italiji pokazala da povezanost postoji. Dijabetes tipa 2 Što se pak tiče utjecaja kave na pojavnost dijabetesa tipa 2, još prije desetak godina neka su istraživanja govorila o više koristi negoli štete. Hardvardska studija u koju je ukupno bilo uključeno gotovo 200.000 osoba pokazala je da oni koji dnevno popiju od 6 do 7 šalica kave imaju 35 posto manju vjerojatnost da će oboliti od dijabetesa tipa 2 u odnosu na one koji popiju jednu ili dvije šalice dnevno. Zanimljivo je da isti učinak ima i kava bez kofeina. Alzheimerova bolest Znanstvenici iz Finske i Švedske u studiji od prije tri godine izvjiestili su da oni koji su pili od tri do pet šalica kave dnevno u svojim srednjim godinama imali 65 posto manji rizik od demencije pa tako i Alzheimerove bolesti u usporedbi s onima koji nisu uopće pili kavu ili su to činili povremeno. Znanstvenici kažu da se umjerenim ispijanjem kave može smanjti rizik od demencije. Ključ je u kofeinu, ali i nekom drugom sastojku kave. Parkinsonova bolest Čini se da postoji veza između veće konzumacije kave i smanjenja rizika za neurovegetativne poremećaje, uključujući i Parkinsonovu bolest. Znanstvenici sa Sveučilišta u Lisabonu utvrdili su da sa svakih 300 miligrama kofeina dnevno za 24 posto smanjuje rizik od ove teške bolesti. No, to se odnosi samo na muškarce jer kod žena rizik pada za samo 14 posto. Znanstvenci za sada ne mogu za sad objasniti ovu povezanost kave i manjeg rizika.
