Ten (Really Good) Reasons to Drink Coffee
I have good news for a lot of you out there: coffee is not just good for
you, it's great for you. In fact, it's not too much of a stretch to
call it a legitimate anti-aging tonic according to the latest research. Think
that's an exagerration? Well, ready below and judge for yourself.
So, yes, there is such a thing as a healthy addiction. Dark Chocolate
and green tea are other examples. Marijuana,
smoking and fast food are all addictions that will kill you,
but coffee according to the latest research is a true friend. And let's
face it: it's hard to find a healthy friendship that will last through the
CAUTION: Coffee and caffeine have their scary side. For more
information, read about The Potential Dangers of Coffee and Caffeine.
1. All Cause and Cardiovascular Mortality. Coffee is one of
those rare factors that can actually reduce your risk of dying. The
reason: it is close to neutral or maybe slightly positive with regards to
cancers deaths but significantly reduces cardiovascular death rates. For
example, a 2008 study followed over a 100,000 men and women for 18 years and
found a clear dose dependent decrease in all cause (overall) and cardiovascular
mortality.  Remember: dose dependence is the gold standard of such
studies and adds more weight to the evidence, because it meant that the more
coffee that was consumed the less the risk of dying. Previous studies had
found the same thing by the way. NOTE: Decaf coffee showed the same
results but to a lesser degree. 
2. Cancer Reduction. The mortality studies mentioned above do not
show significant overall cancer reduction among coffee drinkers. However,
coffee does appear to decrease the risk of certain specific types of cancer,
including cancer of the colon, kidney and non-melanoma skin.  Still
other studies have shown that coffee offers signficant protection against
prostate cancer, especially the most agressive kind.  And, interestingly
enough, the same benefits were found for decaffeinated coffee, indicating the
results came from coffee's phytochemicals and not the caffeine itself.
3) Diabetes. Another mystery of coffee consumption is the fact that it
seems to, in the short term, negatively affect glucose metabolism and insulin
sensitivity yet very significantly reduces the risk of diabetes according to
multiple studies. In fact, those who drank seven or more cups per day had only
one half the risk.
4) Weight Loss and Weight Maintenance. Coffee, both through caffeine and
some of its consituent ingredient, has been shown to help keep those
pounds off. 
5) Dementia and Alzheimer's Reduction. Several studies have shown
that coffee reduces the risk of dementia and Alzheimer's, unlike tea. 
3-5 cups/day confers optimal protection according to one study. In
fairness, one study did not find such a reduction.  However, the reason
is likely the dose as yet another study found that too much coffee resulted in a
loss in cognitive gains.  Again, right around 3 cups appears to be the
6) Alertness and Mental Performance. It's no secret that coffee
boosts your mental sharpness, endurance and acuity. The studies show
alertness and mental performance are enhanced with coffee consumption. 
It may not turn you into Einstein, but it can give you a decided edge. One
study found a dose dependent response where the more coffee that was consumed,
the better the cognitive performance.  NOTE: Decaf coffee did
not have nearly the same benefit.
7) Exercise and Athletic Performance. Coffee boosts lipolysis, the
ability of your body to burn fats and rates of nerve impulse transmission. 
This means greater endurance and, therefore, performance in most exercise and
athletic conditions. One study of middle distance runners showed that it improved
overall race time, final stretch run speed and VO2.  What else
is there, eh? By the way, coffee does this without exclusively relying on
caffeine's epeniphrine-boosting properties. For example, one study showed
that coffee actually dampened the effects of epinephrine. 
8) Reduced Blood Pressure. This one has researchers scratching their
Some initial studies showed that coffee increased blood pressure and thus the
risk of hypertension. However, follow-up work showed clearly that heavy,
"chronic" coffee drinkers actually had lower blood pressure.  The threshhold
is about 5 cups/day and has the strongest correlation in males.
9) Parkinson's Disease. A 2002 meta-analysis shows "strong epidemiological
evidence that smokers and coffee drinkers have a lower risk of Parkinson's
disease".  (This is just about the only disease where smoking is
protective.) The reduction in risk for 3 cups/day is in the range of
25-30%. A previous study from a few years prior had arrived at the same
10) No Fluoride. This is just an apologetic argument to use with your
tea-drinking friends. Green tea is similar to coffee in the sense that it
is a caffeinated beverage that strongly reduces the risk of cardiovascular
disease, some cancers and all cause mortality. However, green tea has a
big disadvantage: an abundance of flouride. Flouride can be hard on the
brain and your precious neurons. Black tea has a lot of flouride and green
tea double that.
11. Prostate Cancer. One recent study found that heavy coffee drinkers,
decaf or regular, had a 20% reduction in all kinds of prostate cancer and a 60%
reduction in the most aggressive form of prostate cancer. 
NOTE: Tell your woman about the wonders of coffee as well. Most of
the benefits above apply to her as well!
