Drinking Coffee Can Be Good For You

Study: Female Coffee Drinkers Less Likely to Die From Heart Disease
Esther Lopez-Garcia, assistant professor of preventive medicine at Autonoma University of Madrid, Spain, and colleagues analyzed data from 84,214 and 41,736 men. Coffee consumption was assessed first in 1980 for women and in 1986 for men and then followed up every two to four years through 2004.
Study participants completed questionnaires on how frequently they drank coffee, and were asked about other dietary habits, smoking, and health conditions. The researchers then compared the frequency of death from any cause, death due to heart disease, and death due to cancer among people with different coffee-drinking habits.
While accounting for other risk factors, the researchers found that people who drank more coffee were less likely to die during the follow-up period. This was mainly because of lower risk for heart disease deaths among coffee drinkers.

Specifically, women who drank two to three cups of caffeinated coffee per day had a 25 percent lower risk of death from heart disease and an 18 percent lower risk of death caused by something other than cancer or heart disease compared to non-coffee drinkers during the follow-up period. Men had a neither higher nor lower risk of death regardless of coffee consumption, according to the study, which was published in the Annals of Internal Medicine.

Even the Smell of Coffee Can Wake You Up

An international group of scientists reports that inhaling the rich, warm aroma of a hot cup of joe may alter the activity of some genes in the brain, reducing the effects of sleep deprivation — no drinking required. Coffee has been a part of the human diet for more than 1,000 years, and is now the most widely consumed beverage worldwide.

Scientists have conducted numerous studies that investigate both the beneficial and adverse effects that coffee can have on health, from the antioxidants it possesses to the possible detriments of too much caffeine. Much of coffee's lift has been attributed to its caffeine content.

But "there are few studies that deal with the beneficial effects of coffee aroma," said study leader Han-Seok Seo of the Seoul National University in South Korea.
Seo and his colleagues allowed lab rats, some of which were stressed by sleep deprivation, to inhale the aroma of coffee. The researchers then compared the expression of certain genes and proteins in the rats' brains.
Some of the genes expressed in the coffee-sniffing, stressed rats expressed proteins that have healthful antioxidant properties known to protect nerve cells from stress-related damage. Their stressed-out counterparts who weren't allowed to smell coffee didn't show these gene expressions. Their findings are detailed in the June 25 issue of the Journal of Agricultural and Food Chemistry. The study was partially funded by the Winter Institute Program of the Korea Science and Engineering Foundation and the Japan-Korea Industrial Technology Foundation.

No higher death risk in long-term coffee drinking

WASHINGTON (Reuters) - Long-term coffee drinking does not appear to increase a person's risk of early death and may cut a person's chances of dying from heart disease, according to a study published on Monday.
Previous studies have given a mixed picture of health effects from coffee, finding a variety of benefits and some drawbacks from the popular drink. The new study looked at people who drank caffeinated or decaffeinated coffee.
Researchers led by Esther Lopez-Garcia of Universidad Autonoma de Madrid in Spain followed 84,214 U.S. women from 1980 to 2004 and 41,736 U.S. men from 1986 to 2004.
They found that regular coffee drinking -- up to six cups a day -- was not associated with increased deaths among the study's middle-aged participants. In fact, the coffee drinkers, particularly the women, experienced a small decline in death rates from heart disease.
The study found no association between coffee consumption and cancer deaths.
"Our study indicates that coffee consumption does not have a detrimental effect," Lopez-Garcia, whose research appears in the journal Annals of Internal Medicine, said in a telephone interview. "It seems like long-term coffee consumption may have some beneficial effects."
There has been a debate among scientists about the health effects of drinking coffee, which typically contains the stimulant caffeine and a number of other important compounds.
The people who took part in the research completed questionnaires on how frequently they drank coffee, other diet habits, smoking and medical conditions. The researchers then studied the mortality risk over the period of the study among people with different coffee-drinking habits.
The study found that women who reported drinking two to three cups of caffeinated coffee per day had a 25 percent lower risk of death from heart disease than women who did not drink coffee. The researchers saw a smaller decreased risk for men but it was not statistically significant.
Drinking decaffeinated coffee was associated with a small reduction in overall mortality risk, the researchers said.
The people in the study had no history of cardiovascular disease or cancer when they entered it. The women were nurses and the men doctors, dentists and other health professionals.
Some studies have indicated coffee is a great source of antioxidants, substances that may protect against the effects of molecules called free radicals that can damage cells and may play a role in heart disease, cancer and other ailments.
Recent studies have offered a mixed picture on the health effects of coffee.
A study that came out in January found that pregnant women who drink two or more cups of coffee a day had twice the risk of miscarriage as those who avoid caffeine. Another study appearing in January found that drinking caffeinated coffee lowered a woman's risk of ovarian cancer.
“…The caffeine in coffee (and tea) acts as a cognitive stimulant and also helps reduce levels of beta amyloid protein in the brain. Accumulations of this protein underlie Alzheimer’s disease,” (http://health.yahoo.com/experts/weilhealthyliving/2952/coffee-can-it-keep-your-brain-in-shape/).
“…Caffeine reduces the risk of dementia by blocking the damage cholesterol can inflict on the body,” (http://www.foxnews.com/story/0,2933,345531,00.html).
“…Caffeine has been shown to prevent skin cancer in laboratory studies… The caffeine was provided in the drinking fluid for the mice and the research found it inhibited ultraviolet light-induced tumors and cancers in this case…,” (http://news.bio-medicine.org/medicine-news-2/Rutgers-research-shows-caffeine-may-prevent-skin-cancer-7240-1/).
