Coffee reduces risk of type 2 diabete

Coffee reduces risk of type 2 diabetes

Reuters 1NOV2006

Coffee drinkers have a substantially lower risk of developing type 2
diabetes than people who abstain from the beverage, a new study shows.

This "striking" protective effect was seen in former coffee drinkers as
well, Besa Smith and co-investigators at the University of California
San Diego in La Jolla report.

"The growing body of literature definitely suggests strongly...that
there is something there," she told Reuters Health in an interview.
Just what that something is isn't clear, but it's probably not
caffeine, she said, because the effect has also been observed with
decaffeinated coffee.

Smith and her colleagues investigated 910 men and women, all of whom
were 50 or older and free of diabetes when the study began.

When the subjects were followed-up about 8 years later, the former and
current coffee drinkers were about 60 percent less likely to have
developed type 2 diabetes.

The protective effects were still seen after the researchers adjusted
the data for variations in physical activity, weight, blood pressure,
smoking and sex among the subjects.

Coffee's protective effect was seen even among people who had impaired
glucose tolerance, an early warning sign of diabetes, at the beginning
of the study.

The researchers were unable to determine how much coffee people needed
to drink to produce the protective effect. But study participants were
generally not heavy coffee drinkers, Smith said.

"Given the increasing prevalence of obesity, impaired glucose
tolerance, and diabetes, and the fact that the majority of adults in
most of the Westernized world drink coffee daily, a coffee benefit
could have widespread impact," she and her colleagues conclude.
"Further investigation is warranted."

I have been a heavy coffee drinker since High School. It didn't keep me
from diabetes, which does not seem to run in my large, extended family.

I was drinking really strong coffee from fresh ground beans everyday for
years. It didn't help me, at least I don't think it did.

Love these studies. You drank it from the wrong side of your
mouth or at the wrong time of the month - they didn't test
those hypotheses.

I still drink my two or three strong mugs a day - and I
doubt it affected any of my ailments one way or the other.

It has been suggested that the contradictory findings with respect to
diabetes and cardiac problems might be explained if the kind of coffee
mattered, e.g. arabica was good and robusta was bad. There is also a
lot if suggestive evidence that method of preparation is important,
e.g., how well the formation of the oxidative by-products found in
stale coffee is avoided. In the opinion of coffee connoiseurs, most
packaged supermarket coffee is stale, and most methods of preparation
allow too much oxidation to happen before your lips reach the cup.

I agree, because I long ago discovered that a small cup of weak
restaurant coffee from the filtered beaker on the hot plate gives me
unpleasant indigestion and angina, whereas a big mug of toe-curlingly
strong coffee prepared by me or one of a very few carefully selected
cafes does not.

I developed this sensitivity to stale coffee, even if weak, at about
the same time as I developed a number of allergies and food
intolerances, along with an expanding waistline, angina, high blood
pressure, and other symptoms of metabolic syndrome. Since shifting to
a much healthier diet I've lost most of the allergies and
intolerances. My low tolerance of wheat products and stale coffee are
the two that have remained.

Unfortunately, a "reduced risk" doesn't mean "zero risk". It would be that
coffee has some slight protective affect that you just can't see. Also,
genetic factors are likely to be a much greater bearing on your present
disposition than coffee.

Obviously, daily coffee drinking is not doing much to stop a lot of people
from becoming diabetic, though. It seems like a pretty useless line of
inquiry to pursue.

When I see reports like this I try to find the original. In
this case I failed - but I did come across some other
supporting references which those fond of the black brew may
like to read.

Unlike some of the researchers, I have no funding support
from coffee producers - I just like my java (and I'd
probably still drink it in moderation even if the reports
were heading in the other direction:-)

Several prospective epidemiologic studies over the past 4 y
concluded that ingestion of caffeinated and decaffeinated
coffee can reduce the risk of diabetes. This finding is at
odds with the results of trials in humans showing that
glucose tolerance is reduced shortly after ingestion of
caffeine or caffeinated coffee and suggesting that coffee
consumption could increase the risk of diabetes. This review
discusses epidemiologic and laboratory studies of the
effects of coffee and its constituents, with a focus on
diabetes risk.

They said "reduces risk," not "prevents."

Here's what "60 percent less likely" probably means:

Out of 910 let's just assume half were coffee drinkers.
That's 455 each. Now, what if twenty percent non-coffee
drinkers developed diabetes? That would be 91.

Sixty percent of 91 is 55. So if _36_ of 455 coffee drinkers
compared to 91 of 455 non-coffee-drinkers, that would be sixty
percent less likely.

Another way to look at the same numbers is 20% vs. 8%

Yet another way would be to say that twelve percent
of people could be protected from diabetes by coffee.

All three descriptions actually mean the same thing,
but sixty sounds a lot better than twelve, doesn't it?

Anyone have the numbers from the actual study report?

Here is the abstract.

Does Coffee Consumption Reduce the Risk of Type 2 Diabetes in
Individuals With Impaired Glucose?

Besa Smith, MPH, Deborah L. Wingard, PHD, Tyler C. Smith, MS, Donna
Kritz-Silverstein, PHD and Elizabeth Barrett-Connor, MD

>From the Division of Epidemiology, Department of Family and Preventive
Medicine, University of California San Diego, La Jolla, California

OBJECTIVE-The purpose of this study was to investigate the
association between coffee intake and incident diabetes based on an
oral glucose tolerance test (OGTT) and examine coffee habits in those
with impaired glucose separately from those with normal glucose at
baseline.

RESEARCH DESIGN AND METHODS-In this prospective study, 910 adults
aged =50 years without diabetes at baseline in 1984-1987 were
followed to 1992-1996, an average of 8 years after assessment of
coffee intake. Logistic regression models were adjusted for sex, age,
physical activity, BMI, smoking, alcohol, hypertension, and baseline
fasting plasma glucose.

RESULTS-Past and current coffee drinkers had a reduced risk of
incident diabetes (odds ratio 0.38 [95% CI 0.17-0.87] and 0.36
[0.19-0.68], respectively) compared with those who never drank
coffee. The 317 participants with baseline impaired glucose who were
past or current coffee drinkers were also at reduced risk for incident
diabetes (0.31 [0.11-0.87] and 0.36 [0.16-0.83], respectively).

CONCLUSIONS-This study confirms a striking protective effect of
caffeinated coffee against incident diabetes and extends these findings
to incident diabetes based on OGTT independent of multiple plausible
confounders.

Hi Wendy and Roger,

I have been a "hard core" coffee drinker since about 1969.... Most
days 6-7 cups, or more. I was diagnosed in 2005. All's I can say is
that maybe I would have become diabetic years before, had I not been
fond of coffee... Who know?

Hey Will,

I was a drinking about that for good ten years from age 30 to 40. Never
slept well at night. It was also the time the kids were young and would
need plenty of mid night help in sleeping well so I attributed my
"light" sleep to kids waking me up.

Later I switched over to tea. My sleep quality has dramatically
improved. I still sleep like a baby! Other than bio-breaks 2/3 times a
night I am still a good sleeper. I don't think coffee played any role
in giving me this prestigious membership. And I would much rather have
my sleep! I am also much more relaxed person now even though my
responsibilities are significantly higher!

Wishing you a very good night sleep :-)

Hi Anil,

I rarely drink coffee after about 3:00 P.M., so I don't think that it
interferes with my sleep so much, although I could be wrong about
that. Also, I did not develop my chronic insomnia until about two
years ago....

You do sound like a very relaxed person, and judging from the tone and
content of your posts, I am sure those around you must really enjoy
your company. If we ever have that asd party someday, you are among
those I would most like to meet. :-)

Wishing you a great day, likewise...

Will, T2
