Even Excessive Coffee Drinking Does Not Increase
Risk of Coronary Heart Disease
April 25, 2006 – The latest study of coffee
consumption did not find any evidence that coffee consumption, at any
volume, increases the risk of coronary heart disease. In fact, the
heaviest coffee drinkers in the study had the lowest risk. This
certainly challenges studies that many senior citizens have read about
for years, saying the stimulant in caffeine is bad for your heart. It
still has not stopped many seniors from drinking coffee - research in
2004 said seniors would not give up coffee for sex.

one source of antioxidants in the American diet.

Coffee is a major source of caffeine, which is the
most widely consumed stimulant in the world and has been implicated in
the development of cardiovascular diseases such as heart attack in
previous studies.
The new study, published online at the Journal of
Circulation, was massive in scope – it looked at 44 005 men and 84 488
women without history of cardiovascular disease or cancer. The study of
women was over 20 years and for men over 14 years.
In the study, men and women were categorized by the
amount of coffee they consumed. Amazingly, the study found the heaviest
coffee drinkers, who drank six or more cups of coffee on a daily basis
for up to two decades, actually had a slightly lower risk of developing
coronary artery disease than those who drank a cup or less each day.
The authors documented 2173 incident cases of
coronary heart disease (1449 nonfatal myocardial infarctions and 724
fatal cases of CHD) among men and 2254 cases (1561 nonfatal myocardial
infarctions and 693 fatal cases of CHD) among women.
Among men, after adjustment for age, smoking, and
other CHD risk factors, the relative risks of CHD across categories of
cumulative coffee consumption were:
● less than 1 cup per mo = 1.0,
● 1 cup per mo to 4 cups per wk = 1.04 (95% confidence interval 0.91
to 1.17),
● 5 to 7 cups per wk = 1.02 (0.91 to 1.15),
● 2 to 3 cups per day = 0.97 (0.86 to 1.11),
● 4 to 5 cups per day = 1.07 (0.88 to 1.31), and
● 6 or more cups per day) = 0.72 (0.49 to 1.07).
Among women, the relative risks were:
● less than 1 cup per mo = 1.0,
● 1 cup per mo to 4 cups per wk = 0.97 (0.83 to 1.14),
● 5 to 7 cups per wk = 1.02 (0.90 to 1.17),
● 2 to 3 cups per day = 0.84 (0.74 to 0.97),
● 4 to 5 cups per day = 0.99 (0.83 to 1.17), and
● 6 or more cups per day) = 0.87 (0.68 to 1.11)
Stratification by smoking status, alcohol
consumption, history of type 2 diabetes mellitus, and body mass index
gave similar results.
The researchers were led by Dr. Esther
Lopez-Garcia of the School of Medicine at Universidad Autonoma de Madrid
in Spain.
For all levels of coffee consumption reported, the
results of the team’s analysis, after adjusting for age, smoking, and
other coronary heart disease risk factors, showed no significant
difference in the relative risks of developing coronary heart disease.
Habits associated with people who are heavy coffee
drinkers include smoking, alcohol consumption, and the use of aspirin
were also examined. The smoking connection was found to be strong and
some say may explain why another study found a link between coffee
drinking and the risk of developing coronary heart disease.
People who consumed large amounts of coffee were
found to drink less tea, were less likely to use multivitamins or
vitamin E, and shunned exercise.
The researchers pointed out that individual
“genotypes” might not follow the general pattern suggested by the study
and could actually exhibit an increased risk of developing coronary
heart disease.
The findings were limited to standard percolator or
drip coffee and not to unfiltered methods of brewing that produce much
stronger coffee. That type of “French press” coffee has been
consistently linked to an increase in LDL (bad) cholesterol.
As in the conclusion of almost all research, the
authors say further study is needed.

Coffee consumption linked to increased risk of heart attack for persons
with certain gene variation
March 7, 2006 - Individuals who have a genetic
variation associated with slower caffeine metabolism appear to have an
increased risk of non-fatal heart attack associated with higher amounts
of coffee intake, according to a study in the March 8 issue of JAMA.
Studies examining the association between coffee
consumption and risk of myocardial infarction (MI – heart attack) have
been inconclusive. Coffee is a major source of caffeine, which is the
most widely consumed stimulant in the world and has been implicated in
the development of cardiovascular diseases such as heart attack,
according to background information in the article. However, coffee
contains a number of other chemicals that have variable effects on the
cardiovascular system. It is not clear whether caffeine alone affects
the risk of heart attack or whether other chemicals found in coffee may
be responsible.

Coffee and tea can reduce the risk of chronic liver disease
Bethesda, Maryland (Dec. 1, 2005) – A study
published today in the American Gastroenterological Association (AGA)
journal Gastroenterology found that people at high risk for liver injury
may be able to reduce their risk for developing chronic liver disease
significantly by drinking more than two cups of coffee or tea daily.
This preventative effect was only seen in people at higher risk for
liver disease due to heavy alcohol intake, being overweight or having
diabetes or iron overload. This is the first study to take a prospective
look at the relationship between coffee and tea consumption and chronic
liver disease in the general U.S. population.

Coffee jump-starts short-term memory
CHICAGO (Nov. 30, 2005) - For the first time,
researchers have demonstrated that caffeine modulates short-term working
memory. The study was presented today at the annual meeting of the
Radiological Society of North America (RSNA).
"We were able to show that caffeine modulates a
higher brain function through its effects on distinct areas of the
brain," said the paper's lead author, Florian Koppelstätter, M.D.,
Ph.D., radiology fellow at Medical University Innsbruck in Austria.

Drinking decaffeinated coffee may be harmful to heart health
Nov. 16, 2005 - Decaffeinated -- not caffeinated --
coffee may cause an increase in harmful LDL cholesterol by increasing a
specific type of blood fat linked to the metabolic syndrome, hints a new
study presented at the American Heart Association's Scientific Sessions
2005.
The Coffee and Lipoprotein Metabolism (CALM) study
included 187 people, randomized to three groups: one that drank three to
six cups of caffeinated coffee a day; another that drank three to six
cups of decaffeinated coffee a day; and a third, the control group, that
drank no coffee.
Some studies have linked coffee drinking to heart
disease, but others have suggested that it is not harmful.
