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.

Soy Products Can Reduce Sperm Counts!

By: Heather Hajek Published: Friday, 25 July 2008 www.healthnews.com C alling all men who want to become fathers! Soy products may reduce a man's sperm count. Based on a recent study, men who consume soy products may have lower sperm counts than those who don't. The study was based on a small group of men who visited the Massachusetts General Hospital Fertility Center from 2000 to 2006. Even though the study found that some of the men who ate soy products on a regular basis had lower sperm counts, the researchers conducting the study are not saying that soy products were the cause of the lower sperm concentrations. The men who had soy products in their diets recorded lower sperm counts than those that didn't, but their counts were still within the normal range. Researchers don't deny that during the study men who consumed soy products had lower sperm counts, but they want people to realize there are other factors other than soy products that may have played a role in th...

Obesity linked to quantity of sleep!

P eople who sleep fewer than six hours a night - or more than nine - are more likely to be obese, according to a new US study that is one of the largest to show a link between irregular sleep and big bellies. The study also linked light sleepers to higher smoking rates, less physical activity and more alcohol use. The research adds weight to a stream of studies that have found obesity and other health problems in those who don't get proper shuteye, said Dr Ron Kramer, a Colorado physician and a spokesman for the American Academy of Sleep Medicine. "The data is all coming together that short sleepers and long sleepers don't do so well," Kramer said. The study is based on door-to-door surveys of 87,000 US adults from 2004 through 2006 conducted by the National Centre for Health Statistics, part of the Centers for Disease Control and Prevention. Such surveys can't prove cause-effect relationships, so - for example - it's not clear if smoking causes sleeplessn...

Biggest explosion!

Thu Feb 19, 3:58 pm ET WASHINGTON (AFP) – The US space agency's Fermi telescope has detected a massive explosion in space which scientists say is the biggest gamma-ray burst ever detected, a report published Thursday in Science Express said. The spectacular blast, which occurred in September in the Carina constellation, produced energies ranging from 3,000 to more than five billion times that of visible light, astrophysicists said. "Visible light has an energy range of between two and three electron volts and these were in the millions to billions of electron volts," astrophysicist Frank Reddy of US space agency NASA told AFP. "If you think about it in terms of energy, X-rays are more energetic because they penetrate matter. These things don't stop for anything -- they just bore through and that's why we can see them from enormous distances," Reddy said. A team led by Jochen Greiner of Germany's Max Planck Institute for Extraterrestrial Physics deter...
